Hydraulic canal project completed in Herkimer

2011-12-07T04:17:00.001-08:00

Herkimer, N.Y. —

Anthony Carlisto, an engineer with Ward Associates, announced at Monday’s Herkimer Village Board of Trustees meeting the hydraulic canal project is finished — and $6,000 under budget.
“It’s been a long haul,” he said.
Trustee Katie Nichols said she is concerned vehicles parking on the grass in the north end of the street will cause problems once snow begins to fall.
There will probably not be room to get a plow through the area, she said.
The board considered putting “No Parking” signs in the area.
Carlisto also updated the board on construction of the port projects, for which he is now “personally responsible.” “We’re going through a transition,” he said
Despite earlier delays, progress on the project has accelerated, he said, crediting favorable weather and the willingness of the construction team.
“I just want to make sure you know we’re doing a good job,” said Carlisto.
Also at Monday’s meeting:
•The board discussed any possible action they could take regarding an ongoing code violation on West Smith Street. The property contains asbestos, they said, and is in need of abatement.
However, said Trustee Mark Netti, due to the current condition of the property, “they’re not going to allow anybody to go in there.”
Village Attorney Nicholas Macri advised the board to send a certified letter to the owner stating the structure is unsafe and must be taken down.
If no action is taken, he said, the board can pursue it with the Supreme Court.
•Mayor Mark Ainsworth proposed the possibility of hiring a new insurance broker. “With the costs that are affecting this village going forward next year, we have to be really aggressive,” he said.
The board suggested contacting the current broker to let them know they will be soliciting a new proposal from them, as well as proposals from other brokers.
The contracts for all village employees will be re-negotiated in June, Ainsworth said.
“They’re going to have to play ball or go home,” he said.
•A public hearing on possible zoning changes was scheduled for 7:05 p.m. on Monday, Dec. 19, in the Herkimer Village Hall meeting room.

Hydraulic Hybrid Trucks Hit the Road

2011-12-07T04:16:00.001-08:00

Hydraulic hybrid technology is moving ahead on a series of fronts, building on its commercial successes with garbage trucks and parcel delivery vehicles.

Now the focus is on proving actual day-to-day performance in these heavier vehicles, where the high power density of fluid power technology shines the best, while laying the groundwork to move the technology into lighter vehicles.

Saving fuel is the obvious benefit of using hydraulic hybrid systems in refuse trucks, along with fewer brake repairs due to regenerating braking energy, but now productivity gains are starting to take the leading position in the value proposition.

This year, the big news for hydraulic hybrid technology came when Environmental Protection Agency administrator Lisa Jackson and Chrysler CEO Sergio Marchionne announced a cooperative agreement to develop and adapt the technology for the light-duty auto market. Using the EPA's own patented technology, the partnership's goal is to move the technology from the lab to the street and design a Chrysler minivan as a demonstration vehicle.
Expectations are that hydraulic hybrid technology can increase fuel efficiency 30-35 percent overall and up to 60 percent in city driving, and reduce overall greenhouse gas emissions by 25 percent.
The EPA is a leader when it comes to developing hydraulic hybrid technologies, specifically series hydraulic hybrid systems. The EPA has been working on them since the late 1990s, teaming with manufacturers such as Eaton and Parker Hannifin.

Hydraulic Leak Delays Test Ahead Of 'Static Kill'

2010-08-03T21:02:00.001-07:00

This is MORNING EDITION, from NPR News. Good morning. I'm Renee Montagne.
STEVE INSKEEP, host:
And I'm Steve Inskeep.
This could be the day that BP plugs its damaged well in the Gulf of Mexico. The oil company says it plans to pump heavy fluid down into the well, and in the lingo of the gas and oil industry: kill it. Also today, BP has a better idea of the scope of the disaster and the fines it will have to pay.
We're going to catch with all of this with NPR's science correspondent Richard Harris, who's been covering this story from the beginning. He's in our studios.
Richard, good morning.
RICHARD HARRIS: Good morning, Steve.
INSKEEP: Okay, the plan to kill the well, as it's put - how's that going to work?
HARRIS: Well, you start with a huge pile of heavy fluid called drilling mud, and it's up on a ship. You take pumps - they're giant pumps on a ship, also. You pump it down 5,000 feet through the water column, and it plugs right into -these pipes plug right in to the blowout preventer, which is down on the seafloor. You very gently turn up the volume of this pressure, and the mud gets - very slowly starts to push in. And...
INSKEEP: Basically, it's like clogging a drain, pretty much.
HARRIS: Like clogging a drain. They call this bullheading, which is a great term, because you can just think of bull's head pushing against something. And they basically want to push the oil that's in the well right now down gently, but firmly and continuously, till it get all the way to the reservoir - 35,000 feet below the seafloor. And if they can do that with the mud, then think about it, you have 13,000 feet of mud stacked up there.
It's heavy enough that, basically, it neutralizes the pressure that's been up in the well all the time. And so the well stops flowing. And that's it. It's killed.
INSKEEP: How is that different from the effort to kill the well with drilling mud that was used back earlier in the summer, with no successful result?
HARRIS: Yeah, the so-called top kill...
INSKEEP: Yeah.
HARRIS: ...which was an utter failure. It is the same principle, pretty much. You want to put heavy stuff in the well and push the oil back down. The difference is now they have this cap on top of the well, so with the top kill, essentially, the mud they put in was just immediately spewed out of the well by the oil that was in there, and it just ended up on the seafloor.
INSKEEP: Like a volcano.
HARRIS: Yeah, exactly. And so basically, that didn't work because there was nothing to hold it in. Now they have this cap, they can hold the mud in place. And so this seems to be something that has a very high degree of likelihood of success.
INSKEEP: Are there still some risks here, though?
HARRIS: There are always risks, although they seem to be pretty calm about this one, because they only have to turn the pressure by just a little bit in order to move the mud down. And so they're not terribly concerned about doing damage to the well.
INSKEEP: And then having gotten the mud in there, you put cement on top of the mud?
HARRIS: Yup, there are a couple of plans for putting in the cement, 'cause that's what you ultimately want to do to make sure it's sealed permanently. The mud will sit there, but you obviously want cement caps. And one way you can do it is you can do the same thing. You can put a slug of cement on the top of the well and gradually push it down. And again, you would want to push it all the way down into the bottom of the well, if you could do that.
Or, remember, we have that relief well that's within like a hundred feet of intercepting at the very bottom of the well. And the original plan, actually, was to pour cement down, pump cement down the relief well and plug using the relief well. They might actually do a combination of both, or one or the other. That remains to be seen.
INSKEEP: We're talking with NPR's Richard Harris on this day when BP might be able to plug this well, permanently, in the Gulf of Mexico.
And, Richard, I'm glad you're here, because a few months ago, you assembled some scientists, independent scientists, to try to estimate how much oil was actually coming out of this well. And now we have from the government a little better idea of how much oil really did come out. How close were you?
HARRIS: Actually those scientists turned out to be remarkably accurate. They estimated about 70,000 barrels of oil and gas a day coming out of the well. The new federal estimate is that something like 62,000 barrels of oil were coming out of the well at the time. They were really almost right on the money. It's quite remarkable. And this was just looking at really raw video that was not high quality. They just had some pretty sophisticated ways of looking at that and figuring out how much oil was flowing.
So let's put these numbers in a little bit of perspective. Now, if you add up over the 86 days, the amount of oil has gradually decreased coming out of the well. But the federal government now estimates that over the entire time, about five million barrels of oil came out the well. BP captured about one million of it - well, not quite. But that left about four million that went into the Gulf. And that's a pretty big number from the standpoint of the ecosystem, but it only represents about five hours of oil consumption in the U.S.
INSKEEP: Wow. Two quick questions, though. How much do have to pay when you spill that many millions of barrels of oil in the ocean?
HARRIS: Well, it's - the fines started at $1,000 per barrel, up to $4,300 per barrel, depending upon negligence, and so on, like that.
INSKEEP: Billions of dollars.
HARRIS: Billions of - so it could be $18 billion, something along those lines.
INSKEEP: Eighteen billion dollars. Well, that raises another question having to do with money, Richard Harris, and also having to do with oil. There are still millions of barrels underneath the Gulf in this well that's being plugged as soon as today, right?
HARRIS: That's correct. And there's been a lot of speculation about whether BP would go back in and try to get it. They do have - they've drilled these two relief wells that are tantalizingly close to this reservoir. But yesterday, somebody at BP, a vice president was asked: Are you going to go after that oil with those relief wells? He said, absolutely not. We're going to seal it up, and we're going to leave them alone.
INSKEEP: Not worth the PR costs or...
HARRIS: Apparently not.
INSKEEP: ...or the risk. Or the risk.
Richard, thanks very much.
HARRIS: My pleasure.
INSKEEP: That's NPR's science correspondent Richard Harris this morning.

Hydraulic drive trencher

2010-07-14T05:36:00.001-07:00

The improvements made as a result of the experience of the 300P series 1 to 3 have made it possible for the UNAC research department to design and produce the UNAC series 4 300P, equipped with a new generation 300hp Caterpillar diesel engine. The UNAC 300P carrier is versatile. Changing from one tool to another - saw, chain orvibrating ploughshare - can be done in an average time of one hour. This makes it possible for the same carrier to be available for all types of worksite. Thanks to the tilt corrector and hydraulic offset, the tool remains permanently vertical.

The 300P also exists in a 500hp version. On the same basis as the 300P carrier, UNAC has developed the 300C carrier, on caterpillar tracks. It has been studied for work in all conditions, and is equipped with a chain and vibrating ploughshare.

Hydraulic fracking spells disaster

2010-05-07T21:01:00.000-07:00

Despite industry claims that the rapidly expanding practice of hydraulic fracturing to extract natural gas from deep underground shale layers is “perfectly safe,” on April 15 the Pennsylvania Department of Environmental Protection fined Houston-based Cabot Oil and Gas $240,000 for causing the contamination of 14 residential water wells in Dimock Township, Pa.
The company was also ordered to plug three gas wells it was operating in the town, which sits atop the Marcellus Shale formation, and was banned from drilling in the area. One water well in Dimock exploded last year, and DEP inspectors witnessed gas bubbling up at the base of eight other wells in March. Despite the ruling, Cabot has plans to drill 100 new wells in Dimock this year.
Independent newsroom ProPublica has reported on 50 similar cases across Pennsylvania, including reports of fish kills, water and air pollution, fires, out-of-control flaring, human illnesses and animal deaths.
The concern over the safety of hydraulic fracturing has prompted calls for a moratorium on drilling in Pennsylvania. In the process, often referred to as fracking, 2 to 9 millions of gallons of water, mixed with sand and up to 250 chemicals, are pushed into underground shale layers to release natural gas.
In January the Pennsylvania state Legislature opened up 32,000 additional acres of state forest land to be leased for drilling. As a result, 692,000 acres of the 2.1 million acres of state forest land are now open for gas wells. During a recent push to expand the practice into the Delaware River basin, the Philadelphia City Council was pressured to pass a resolution on March 25 calling for an environmental impact statement before any new permits are issued.
Fracking has been in use for a number of years throughout the U.S., particularly in the Southwest. Five natural gas sites border the town of Dish, Texas, in a quarter-mile complex. In nearby Fort Worth, Texas, 1,400 wells have been drilled in urban areas, many near schools and residential centers.
Speaking at a meeting at Temple University’s Department of Civil and Environmental Engineering on April 16, Dish Mayor Calvin Tillman described how carcinogenic air pollution from natural gas drilling has damaged the quality of life in his town of 180 residents. The town sits atop the Barnett Shale, a geological formation similar to the Marcellus Shale.
Using his own money, Tillman has been traveling to Pennsylvania and New York to warn about the dangers of the gas boom. In his small town, trees are dying on a 30-acre farm that adjoins a labyrinth of small underground pipelines used to transport fuel from the fracking wells to outside markets. Horses have also fallen ill. Residents report problems with frequent nausea, severe headaches, breathing difficulties, chronic eye irritation, allergies, throat irritations and even brain disorders.
When Texas state inspectors, who are usually linked to the drilling companies, reported they could not find any problem with the wells, Dish town officials hired an environmental firm to collect one-day air samples near the compressors. Their study found high levels of 15 chemicals, including benzene, a known carcinogen. As a result the Texas Commission on Environmental Quality conducted air studies at 94 sites in the region. They found two sites with very high levels of benzene and 19 others with levels that raised concern.
In April, blood and urine testing of 28 adult Dish residents revealed that half the residents had slightly elevated levels of benzene and other contaminants. Four residents tested positive for benzene, including Tillman. Tillman noted that no testing was done on children, pregnant women or the elderly — groups likely to be most susceptible to the contaminants. Tillman’s water also tested positive for traces of styrene, ethyl benzene and xylene.
Growing concern over the danger of fracking has led to a push for legislation in Pennsylvania that would require drillers to disclose chemical ingredients in hydraulic fracturing fluids. Other proposed legislation calls for a moratorium on drilling until environmental impact studies can be performed. Both bills have yet to be passed and face mounting opposition from the natural gas industry.
Nationally, the oil and gas industry won exemption from major provisions of the Safe Drinking Water Act, the Clean Water Act and other federal environmental laws with the passage of the 2005 Energy Bill. The bill’s “Halliburton loophole” protected the company from having to reveal the composition of their fracturing fluid, despite the fact that the list of hazardous substances compiled by the Environmental Protection Agency’s Superfund — the program established to address abandoned hazardous waste sites — includes toxic profiles on benzene, styrene, toluene and other agents known to be in the mix. Efforts are also underway to challenge this legislation.
The EPA announced it will spend $4.4 million to start a study on the impact of fracturing in October, but Dr. Michel Boufadel, director of the Environmental Hydrology and Hydraulics Laboratory at Temple University College of Engineering, expressed concerns that the EPA’s study does not go far enough.
Speaking at the April 16 meeting, Boufadel noted that very few scientific studies on fracking have been conducted by researchers not connected to the drilling industry. He also pointed out that most studies assume that any leak of water contaminated by fracturing fluids would spread horizontally from a holding tank and be detected by ground level monitors.
Boufadel explained that the 250 chemicals contained in the fracturing fluid create “gooey, high density water” — a gel that suspends the sand particles needed to work into cracks in the shale layers. The result is “radioactive water six times more saline than sea water and containing known carcinogens.”
“If you don’t account for this heavy density you would expect water to move outward, but the reality is that it moves down,” Boufadel stressed. “If you only use existing traditional models of monitoring wells at ground level, you won’t detect contamination until it’s too late.”

D*1FP servo valves enhance large hydraulic systems

2010-03-14T04:53:00.001-07:00

Parker Hannifin has brought out the D*1FP range of pilot-operated servo proportional valves.

These are based on the company's direct-operated DFplus hydraulics control valve, which features Parker's Voice Coil Drive (VCD) technology.

The control behaviour of the Parker Hannifin D*1FP series valves ensures high stability in operation and easy, time-saving installation and set-up.

The VCD is based on the same principle used to vibrate loudspeaker diaphragms.
Parker is using it to control the high forces within hydraulic valves.
By producing dynamics on a par with modern servo valves, the VCD technology results in a much simpler valve structure.
The new pilot-operated D*1FP series has transferred the advantages of the VCD to larger frame sizes and higher flow-rate valves.
The high dynamics and precision of each new pilot valve deliver optimum control of the main spool, resulting in servo-class performance from the complete valve.
The control behaviour of the valves ensures high stability in operation and easy, time-saving installation and set-up.
Whether in the direct or pilot-operated valves, the VCD technology offers the same benefits of robust design and long life.
A new safety concept with the pilot valve can also reduce the need for additional shut-off valves in hydraulics systems.
It ensures the main stage is hydraulically balanced at power down and the main spool is in a safe position.
The D*1FP range is available in four sizes: NG10 (CETOP05), NG16 (CETOP07), NG25 (CETOP08) and NG32 (CETOP10).
With flow rates of up to 3000 litres a minute, the valves bring the advantages of VCD technology to almost any size of hydraulics system and are supported around the world by Parker's global network of manufacturing, sales and customer-support centres.

Australian Brake Controls’ air/hydraulic brakes keep tractors and trailers controlled

2010-03-03T02:48:00.001-08:00

A CONTRACTOR from Mel-Ray Industries has installed a dual-line air/hydraulic braking system from Australian Brake Controls in his tractors and trailers.

According to Ray Galdes, towing a heavy trailer around worksites can be a potentially hazardous, high maintenance undertaking.

Trucks, tractors and specialized machinery can be subjected to loads that will place unusual stresses on standard components, including high demands on braking systems in situations where operators need to selectively and powerfully apply stopping and holding power.

Examples include going down a one-in-four slope with a 90-degree turn at the bottom. Gravity will see the trailer trying to push straight ahead, off the road. Galdes says he helped increase the responsiveness and control over the vehicles with the Australian Brake Controls system.

His latest system enables the driver to simultaneously control both the tractor’s hydraulic brakes and trailer’s air brakes from the same brake pedal. The operator can also operate the trailer brakes separately using an in-cab hand control.

Galdes says air brakes are the most effective, as other types of brakes get burned out quickly on slopes.

Australian Brake Controls engineered a system which incorporates a tractor-mounted half horsepower electric compressor feeding a nine litre pneumatic holding tank linked by airlines to the trailer brakes.

This pneumatic system is synchronized with the tractor’s hydraulic system via a reaction valve that automatically senses the amount of pressure being applied to the hydraulic system and turns this into an air signal for the trailer’s air system when the brakes are applied.

Hydraulic fracing dominates ExxonMobil-XTO merger hearing

2010-01-26T08:03:00.000-08:00

A congressional hearing that ostensibly was supposed to consider a proposed merger’s market impacts quickly became a forum for debating whether to federally regulate hydraulic fracturing.

Chairman Edward J. Markey (D-Mass.) convened the Jan. 20 hearing of the House Energy and Commerce Committee’s Energy and Environment Subcommittee to examine energy market impacts of ExxonMobil Corp.’s proposed $41 billion purchase of XTO Energy Corp. “This merger heralds a fundamental long-term shift in US energy markets, and one that deserves our close attention,” he said in his opening statement.

But the discussion quickly turned to hydraulic fracing because the proposed combination’s agreement includes a termination provision if Congress enacts legislation making hydraulic fracing too costly and uneconomic.

“This country has a propensity to regulate. We need to protect our shareholders,” ExxonMobil Chief Executive Officer Rex W. Tillerson told the subcommittee.

ExxonMobil wants to acquire the Fort Worth, Tex., independent because XTO’s US unconventional gas resource base and technical expertise would go well with the major’s global reach, research and development capabilities, and financial capacity, Tillerson said.

“The development of our combined resources will create the opportunity for more jobs and investment in the production of natural gas across many parts of the United States,” Tillerson said. “It will support our nation’s economic recovery, strengthen [its] energy security, and help meet [its] environmental goals.”

Focus on gas
Bob R. Simpson, XTO chairman and founder, said the company’s management decided soon after it started to focus not only on gas, but also on long-lived, high-producing reserves. That led it to tight shale gas, where it eventually became an industry leader, he indicated.

“In reviewing our future path, we realized that we needed to look at options to take what we have achieved and bring it to a new level,” he testified. “We recognized that the opportunities before us could best reach their potential if we could find an organization that could bring additional scale, technology, and financial capacity to the work we have been doing. We found that organization in ExxonMobil.”

Markey suggested that the proposed merger has positive aspects, including the signal that another multinational oil company is willing to invest in developing unconventional US gas resources. But he also said that Congress wants to make certain those resources are developed safely, which is why it asked the US Environmental Protection Agency to study hydraulic fracing’s operating record.

Republicans on the subcommittee said the technology is safe. “It is well known that gas will play a more prominent role in a carbon-restrained world,” said ranking minority member Fred Upton (R-Mich.). “In fact, the success of any climate-change policy will need to rely heavily on gas. Yet some members of Congress are seeking policies that would take a majority of our domestic gas off the table.”

Several Democrats said the process uses toxic substances that would create serious problems if they entered drinking water supplies. Rep. Diana DeGette (D-Colo.), who is not a member of this subcommittee, was allowed to participate because she introduced a bill last year to federally regulate hydraulic fracing under the Safe Drinking Water Act.

“I support hydraulic fracturing,” she said. “My bill would not make it illegal or impractical. It simply would require disclosure of ingredients in an emergency situation while protecting proprietary information.”

Fluid confined
Tillerson and Simpson both said they would not have a problem as producers disclosing ingredients in hydraulic fracing fluid, which is primarily water. They also pointed out that the process occurs several hundred feet below drinking water supplies, and that concrete casing keeps hydrofrac fluid confined while it’s pumped below the surface.

States already regulate hydraulic fracing aggressively, they continued. DeGette immediately challenged that idea, noting that only four states have regulations that specifically deal with the process. The executives responded that several others have water-management regulations that serve similar purposes.

They also contended that federally regulating hydraulic fracing simply would add another layer to a process that states already regulate well. Restricting its use would harm conventional production too, Tillerson added. “A lot of conventional wells use hydraulic fracturing to make production commercial,” he said.

When DeGette asked them how much they think having to comply with SDWA regulations in using hydraulic fracing would cost their companies, the ExxonMobil and XTO executives said they did not know. “Much of it would depend on how EPA decided to implement its regulation,” Tillerson told her. “I don’t know what would be in it, and neither do you.”

Markey concluded the hearing by stating, “There is no secret plot on this side of the aisle to ban hydraulic fracturing.” But when he was asked by reporters afterward if he planned to schedule DeGette’s bill for markup, the subcommittee chairman replied, “I’m going to have to have further discussions with her on it before I decide.”

Away in a manger - or a hydraulic shop

2009-12-25T19:58:00.000-08:00

Eight years ago, I set up a CNN e-mail alert for "Osama Bin Laden." It was to alert me when he'd been caught or killed, you see.

View LargerDue to the lack of suitable Christmas tree specimens in Afghanistan, B Co 603rd ASB had to make do with what they had: Hydraulic line, a printer and goodies/decorations from home. (courtesy Staff Sgt. Paul Ramus)

The info in the forwarded articles is always very mundane, and I feel stupid whenever I receive one. Still, I haven't canceled them.
I keep receiving them for sentimental reasons, I guess, to remind me of a time when such dramatically positive developments seemed possible - redemptive even.
Meanwhile, the war in Afghanistan continues, and may have another eight years on the way on top of the eight we've already seen.
I have a child who is eleven. The war's been going on since she was three. She'll likely be in college before it's over.
I'm lucky, though. I can't imagine what it must be like to leave your young children behind while you go off on yet another tour of duty.
Frankly, I'm not sure I'd be able to go through with it. I'm glad I've never had to test that theory.
A couple of years after 9/11, when the Iraq war started, I spent a lot of time feeling sorry for American soldiers on the basis that they and their families were being abused and misused by their elected leaders.
I still feel that way to an extent, but I've long since stopped feeling sorry for them - for the simple reason that they don't feel at all sorry for themselves.
The servicepeople I know, and almost certainly the ones you know as well, don't consider themselves particularly unfortunate. Sure, they gripe about bureaucracy and politicians and regulations, as soldiers the world over have since the beginning of standing armies.
But they continue doing what they want to do, living the lives they've chosen to live, proudly, patiently, and largely without regret.
So when I relay to you the accompanying photo of a makeshift Christmas tree in a hydraulic shop on a U.S. base in largely treeless Afghanistan - reprinted with permission from my friends in the Ramus family - it's not to make you feel sorry for anyone or have pity for anyone, and it's certainly not to incite any particular political opinion either way.
It's there to reinforce the notion that Christmas is what we make of it, and happens wherever it is celebrated. Like that original scene in a manger in the Holy Land, it needs no fancy trappings and has no minimum requirements other than a belief in the possibility of redemption.

GSF to distribute Interfron hydraulic power units

2009-09-22T04:08:00.001-07:00

GSF Slides has been appointed sole distributor for the UK, Ireland and Australia for the Interfron range of backpack and hydraulic power units.

The SP700 and VP700 are battery-powered backpack units that provide hydraulic power for cutting tools and other hydraulic equipment such as hydraulic jacks used by emergency services as well as in many other situations.

'The range of battery-powered backpacks gives emergency crews complete freedom from petrol-driven or vehicle-mounted power supplies,' said Jon Lye, managing director, GSF.
'No hydraulic extensions and no attachments mean no entanglements, which in low-visibility, high-risk environments, reduce accidents and increase access to enclosed and otherwise inaccessible spaces,' he added.
The SP700 and the VP700 can be fitted with the appropriate hydraulic connectors, enabling the units to operate rescue tools from all major manufacturers, including Holmatro, Amkus, Lukas, Zumro, Weber, TNT, Lancier, Nike Centaur, Resotec and Enerpac.
The units can be adjusted to use hydraulic pressure at 5,100, 9,200 and 10,500 psi.
Each unit has a total weight of approximately 18kg (40lbs).
'Our backpacks have 30 minutes of operational use and it takes seconds to refit a new battery,' said Lye.
Other key features include (on the VP700) integral control valves, which enable control of equipment extensions such as hydraulic rams.
In addition, the VP700 has been designed for varying emergency conditions.
The VP700 is water tight to a depth of 2m, meaning it is a quick, free-moving system suitable for sea and water rescues.
The Interfron range also includes three conventional, free-standing petrol-driven hydraulic pump units, which are designed with protective roll cages, scope to connect two tools at once and built-in controls.

After 30 years, hydraulic canal getting a makeover

2009-09-02T20:17:00.000-07:00

Just stand outside Jim and Barbara Gilbert’s home, at 518 Willow Ave., in Herkimer, for five minutes and the Hydraulic Canal’s impact becomes clear.
In between swats at insects swarming around her head, Barbara describes what it’s like to live next to the canal, which has been a blight in the village for decades.
“The kids can’t even be out in the yard,” she said, referring to visits by family. “They came out here the other night, but they couldn’t stay out. The mosquitos are wicked.”
Numerous residents living along the canal have for years informed village officials of similar difficulties, dealing with bugs, rodents and occasional dumping that contribute to the canal’s presence as a health hazard and eyesore.
But after over 30 years of serving no industrial or water supply purpose, as well as numerous mayors and village boards failing in their pursuit of government funds, sections of the stagnant waterway are finally scheduled to be filled.
The village’s application for state Community Development Block Grant funds was approved in the 2009 competitive round. Part of nearly $35 million in grants announced by Governor David Paterson last week, Herkimer will receive $599,000 to fill in village-owned portions of the canal.
With grant applications rejected in 2007 and 2008, village Trustee Katie Nichols attributed 2009’s success to a build up of data that outlined the blight.
“There are letters we found in the old files that went back to previous mayors and boards,” Nichols said, commenting on the process beginning before her becoming a trustee 12 years ago.
A communication from the county Highway Department in 1998 to village Department of Public Works officials detailed what could be done to address the problem back then, she added.
The approved proposal calls for installing culvert piping, filling in the canal with dirt and landscaping a green bed. Previous cost estimates put the village contribution at upwards of $100,000 to fully fund the project.
Details on actual cost and scope are yet to be determined.
The work will likely begin in 2010, according to Nichols. And the state typically allows two years for completion of a project, she added.
“It’s been a long time already,” Barbara said, “but it’ll be great when something’s finally done.”
What sections get done?
The original project proposal only called for German to Suiter streets and Folts to Green streets.
The section of Willow Avenue, which includes the Gilberts’ property and several other parcels, wasn’t added to the project until earlier this year, however.
For 35 years the Gilberts have lived on the canal’s bank, and Jim says he has struggled to get action for pretty much the duration.
Jim said he even ran a failed campaign for a village trustee seat in the 1980s in an attempt to address the problem.
So upon learning of the most recent proposal, which excluded his street, Jim approached the Telegram with his argument.
He believed the section of canal that extended past German Street along Willow Avenue was village owned.
County tax officials in interviews confirmed past documentation that showed village ownership. And following a survey that clearly defined the relationship between the property’s deed and tax maps, the village decided to add the roughly 300 feet.
After hearing the canal project gained funding, and it included his street, Jim looked at his home and yard and then glared at the canal, a mere five feet past his driveway. “This all will be so much better when they get this filled in,” he said.
Nichols said funding for the additional section was made possible in part as a result of removing a Steuben Road Bridge repair — whose completion had been sped up by state mandate.
Village officials also said portions of canal that pass through the south side of East State Street aren’t eligible for government funds, as most are privately owned.
Some sections of canal do belong to the county, which already installed a parking lot over the canal off of North Washington Street. The county office’s parking lot project — previously reported at a cost of $200,000 — was similar to the village proposal, including a culvert to allow water to flow through and filling the land.

Shoigu confirms hydraulic impact causes HPP accident

2009-08-18T02:20:00.001-07:00

SAYANO-SHUSHENSKAYA HPP, August 18 (Itar-Tass) - Russian Emergency Situations Minister Sergei Shoigu has again confirmed that a hydraulic impact caused the Monday morning accident at the Sayano-Shushenskaya hydropower plant. “The main version of the emergency is a hydraulic impact, but it is necessary to find out what caused the hydraulic impact,” he said.

RF Energy Minister Sergei Shmatko agreed with him. “It is so far early to speak about the causes,” he said.

Shoigu also said that no emergency situations took place at the aluminium smelters in Khakassia, in the Krasnoyarsk Territory, in the Kemerovo and Novosibirsk regions. “Owing to the modern equipment installed at them serious breakdowns were prevented,” Shoigu stated.

The RF emergencies minister heads efforts aimed at the elimination of the aftermath of the Sayano-Shushenskaya hydropower plant’s accident. He personally controls the progress of all operations in site. A large group of the ministry’s specialists is also working at the emergency site together with experts from the Energy Ministry, RF Federal Service of Environmental, Technological and Nuclear Supervision (Rostekhnadzor) and other services.

Bobcat launch new precision hydraulic excavators

2009-07-31T08:48:00.000-07:00

Bobcat has launched a completely new generation of 3 tonne mini-excavators, the 3.2 tonne E32 conventional tail swing and the 3.5 tonne E35 zero tail swing models.

Both excavators feature smooth and precise workgroup control, exceptional hydraulic performance, enhanced convenience and comfort for the operator, as well as increased reliability.

Designed to achieve the highest performance with exceptionally smooth movements, the E32 and E35 mini-excavators combine maximum productivity with the ability to carry out jobs with precision and fingertip control.

The load sense piston pump and the closed centre valve enable exceptionally fine metering of hydraulic flow for smooth, precise control of machine functions, while reducing hydraulic noise.

The boom and dipper arm cylinders are cushioned to provide a smooth, end-of stroke operation.

Operator comfort has always been an important feature of Bobcat mini-excavators.

In the E32 and E35, the operator area offers the latest comfort, visibility and space standards.

The canopy and cab are designed so the operator has plenty of space for their feet and legs as well as a very comfortable work environment.

The cab version is equipped standard with heating and ventilation.

Air conditioning is available as an option.

Bobcat excavators are known for their reliability, an important factor contributing to the low overall lifetime operating cost of a Bobcat excavator.

CAD techniques, endurance testing of components and assemblies under extreme conditions, and highly durable materials are used to ensure reliability.

These processes underpin the design of the E32 and E35, which have the same upper-structure, cab/canopy and workgroup.

Ritter wants study instead of regulation of hydraulic fracturing

2009-07-10T21:45:00.000-07:00

Gov. Bill Ritter is calling for a study of hydraulic fracturing in lieu of immediate federal legislation that he says could result in a potentially intrusive regulatory program for the oil and gas industry.

However, despite comments suggesting otherwise by Ritter, a spokesman for U.S. Rep. Diana DeGette, D-Denver, says she is not backing off trying to get the legislation passed.

The legislation would subject hydraulic fracturing to the federal Safe Drinking Water Act and require disclosure of chemicals used in the practice.

Fracturing involves sending pressurized fluids down wells to crack open rock formations and increase natural gas flow. It is essential to gas development in places such as western Colorado.

Advocates of the legislation say fracturing could be harming drinking water. The industry says the practice is well regulated by states, and that there have been no documented cases of it contaminating drinking water.

In comments delivered at a Colorado Oil & Gas Association convention in Denver on Thursday, Ritter indicated he thought that bill was premature and possibly unwarranted.

“I don’t for a moment discount the concerns of those who worry about protection of drinking water supplies. But I also believe that we have to understand the problems and the risks before we act,” he said.

Colorado’s new oil and gas rules, which were sought by Ritter, include a requirement for companies to maintain an inventory of fracturing substances and make it available upon request by the state. He said he talked to DeGette about Colorado’s effort “and what her amendment was likely to do in terms of trying to have a one-size-fits-all approach.”

“We believe we addressed it,” Ritter said. “The states should address this issue one state at a time and she agreed at that time to go instead to something that would be more in the way of a study instead of an amendment that would prescribe a certain way of every state having to put in place these rules. I thank the congresswoman for having done that.”

But DeGette spokesman Kristofer Eisenla said that although she agreed with Ritter that more data is needed about hydraulic fracturing, she’s moving forward with her bill.

“I do know they had a very good conversation. She understands his concerns, but this is how she’s proceeding,” he said.

Asked to clarify things, Ritter spokesman Evan Dreyer said in a statement: “This legislation won’t be heard for months and months, so undertaking a study now is the right thing to do because a study will likely be done before the legislation would even come up for hearing. (DeGette) just wants to keep all options available, and that’s in keeping with what she and the governor talked about and agreed upon.”

Ritter drew heavy industry criticism for seeking new oil and gas rules designed to produce more balance between energy development and protection of the public, wildlife and the environment. Although drilling activity has fallen sharply nationally because of dropping natural gas prices, energy companies say the new rules helped exacerbate the problem in Colorado.

However, Ritter has undertaken numerous recent efforts to help boost the industry, and he outlined them in his speech Thursday. They include helping promote expansion of pipeline capacity to out-of-state markets, seeking funding for use of compressed natural gas in vehicles, encouraging use of natural gas by utilities and opposing a proposal to repeal an industry federal tax deduction.

Ritter said natural gas isn’t just a transition fuel to what he calls his New Energy Economy, but a permanent part of it. He said the fuel is important to addressing climate change, reducing energy dependence and increasing national security.

He told industry representatives Thursday, “Natural gas is a vital part of our strategy to build a strong economic future for Colorado, and I want to work as a close-knit team to get us there.”

Nate Strauch of the Colorado Oil & Gas Association said that despite the industry’s differences with Ritter over the new rules, it’s looking forward now.

“Certainly we were very pleased to hear what the governor had to say about Colorado’s clean-burning natural gas,” he said.

As for the fracturing legislation, “We’d certainly hope that Congresswoman DeGette heeds the governor’s advice. … Certainly we believe it’s an unnecessary bill and feel very happy to hear that the governor feels the same.”

States already regulate hydraulic fracturing well, officials testify

2009-06-06T23:43:00.000-07:00

States already regulate hydraulic fracturing aggressively and effectively, and a federal law would be redundant, two officials told a US House subcommittee on June 4.

"As the head regulator of oil and natural gas development in North Dakota and an office of the Interstate Oil and Gas Compact Commission, I can assure you that we have no higher priority than the protection of our states' water resources," said Lynn D. Helms, director of North Dakota's Department of Mineral Resources.

"Within our respective states, we are responsible for implementing the state regulations governing the exploration and development of oil and gas resources. First and foremost, we are resource protection professionals committed to stewardship of water resources in the exercise of our authority," said Scott Kell, president of the Ground Water Protection Council and deputy chief of the Minerals Resources Division in Ohio's Department of Natural Resources.

But a former director of New York City's Water and Sewer System told the House Natural Resources Committee's Energy and Minerals Resources Subcommittee that current state regulations are inadequate.

"All the improvements they've talked about are welcome. What we're dealing with is good housekeeping. All that has to happen is to have 2% of the wells that are planned go south and we'll have thousands of incidents," said Albert F. Appleton, who is now an infrastructure and environmental consultant.

'Take the initiative'

"The industry could help by developing biodegradable fracking fluids. I don't understand, for the life of me, why it hasn't taken the initiative," he added.

They testified, with Douglas Duncan, associate coordinator of the US Geological Survey's Energy Resources Program, and Mike John, eastern division vice president of corporate development and corporate resources at Chesapeake Energy Corp., at a hearing called by the subcommittee's chairman, Jim Costa (D-Calif.), to examine issues associated with shale gas production.

"Shale gas actually is not new. It's been developed for almost 50 years and could play a sizable part in the US energy portfolio. A single play, the Barnett shale, produces 6% of all gas consumed in the US today," he said in his opening statement.

"While this is a great opportunity for the country to have access to a significant reserve of clean burning fuel well into the future, for some unfamiliar with the oil and gas industry, it has raised concern over the potential impact to water quality and use from the practice of hydraulic fracturing," said Doug Lamborn (R-Colo.), the committee's ranking minority member.

"Hydraulic fracturing has been used by the oil and gas industry since the late 1940s," he continued. "More than 1 million frac jobs have been completed in the US since the technique was first developed. And there have been no demonstrated adverse impacts to drinking water wells from the fracking process or the fluids used in the process."

Another subcommittee member disagreed. "This is not an issue that's newly important. It's been around for a long time," said Maurice D. Hinchey (D-NY). Congress dealt with it when it passed the Safe Drinking Water Act in 1974, but a later group of federal lawmakers exempted oil and gas drilling under the 2005 Energy Policy Act, an action which needs to be reversed, he said.

Will reintroduce bill

Hinchey and Diana DeGette (D-Colo.) said following the hearing that they plan to reintroduce a bill next week that they initially offered in 2008 which would bring oil and gas drilling back under the SDWA. "This bill would make drillers subject to the same reporting requirements as any other industry under the SDWA. They would have to file reports about what chemicals are in the fracking fluid," she told reporters during an afternoon teleconference.

"We are being contacted by people from around the country who report bad experiences from drilling near their property. We're not trying to do anything revolutionary. We're trying to restore a safe, solid piece of legislation that was passed back in 1974," said Hinchey, who also participated.

But Kell said that reports of problems have been exaggerated. "In recent months, the states have become aware of press reports and websites alleging that six states have documented over 1,000 incidents of groundwater contamination from the practice of hydraulic fracturing. Such reports are not accurate," he said.

Officials from Ohio, Pennsylvania, Pennsylvania, New Mexico, Alabama, and Texas wrote letters to GWPC Executive Director Mike Paque disproving the reports, Kell continued. A sixth official, from Colorado, did not respond because he had not been on the job long enough, he added.

In his May 29 letter to Paque, Texas Railroad Commission Chairman Victor G. Carillo said that a majority of 354 active groundwater cases associated with the oil and gas which were reported in the state in 2007 involved "previous practices that are no longer allowed or result from activity now prohibited by our existing regulations. A few cases were due to blowouts that primarily occur during drilling activity. Not one of these cases was caused by hydraulic fracturing activity."

Safely used since '40s

Mike John of Chesapeake Energy acknowledged that hydraulic fracturing has become somewhat controversial, but added that it has been safely used since the 1940s. "It is very important to reiterate that these deep shale formations exist thousands of feet below the land surface and are separated from freshwater supplies by layers of steel casing, protected by concrete barriers as well as millions of tons of hard, dense solid rock geologic formations," he said in his written statement.

He also submitted a fact sheet which listed fracturing fluid additives, main compounds, and purposes, including hydrochloric or muriatic acid, borate salts (which maintain fluid viscosity as temperatures rise), petroleum distillate (to "slick" the water to minimize friction), and ethylene glycol (to prevent scale deposits in the pipe). "Additives used in hydraulic fracturing fluids include a number of compounds found in common consumer products," the fact sheet said.

But Appleton characterized fracturing fluid ingredients as "a witch's brew of toxic chemicals, nearly all of which are intrinsically hazardous to the environment." They are dangerous, he maintained, because they don't biodegrade: "Once in the environment, they stay there. Most of them bioaccumulate. The remainder volatize, removing them from water and land, but adding them to the atmosphere where they become contributors to global warming."

Hydraulic fracturing introduces these chemicals into the environment by leaving a significant portion of the fluid underground, where it is free to migrate into groundwater, he continued. More oversight is needed to assure that wells are properly drilled so their integrity is not breached, that the fracking fluids are properly handled and not spilled, and the liquids are properly disposed, he said in his written statement.

Appleton said that shale gas drilling is inappropriate in any area that is a major drinking water source, that zoning is essential particularly in rural areas to minimize impacts of incompatible land uses, and that a system of impact payments to local rural governments will be needed to deal with community infrastructure issues.

'Inaccurate information'

That drew a strong reaction from one subcommittee member. "Mr. Appleton essentially said the oil and gas industry is making so much money it can afford to be over-regulated," said Dan Boren (D-Okla.). "Well, natural gas producers in my district are stacking rigs and companies like Frac Tech are laying off employees. I'm proud that I'm supported by the oil and gas industry because it employs a lot of people in my state, and I'm tired of people trying to shut it down with inaccurate information."

Hinchey pressed Kell for information about oil and gas industry support of the GWPC. Kell said that the group gets its main support from government agencies including the US Department of Energy, the Environmental Protection Agency, and numerous industries besides oil and gas. "Our opinions are not for sale. Our emphasis is on protection of water resources," he declared.

Quite a few states already require disclosure of ingredients in hydraulic fracturing fluids, he added. "As a member of the GWPC and an Ohio official, I don't believe any federal regulation of hydraulic fracturing is necessary," he said.

When Cynthia M. Lummis (R-Wyo.) asked what impacts federal hydraulic fracturing regulations would have on state programs, Helms responded that Alabama spent two years rewriting its regulations in the 1990s after losing a lawsuit brought by an environmental organization. "We're also concerned that requiring additional regulations will divert states' resources from other higher priority programs," Kell said.

When she was asked about this during her teleconference, DeGette replied: "The reason we passed the [SDWA] to begin with is that we decided safe drinking water is a national priority. Also, water like any resources crosses state lines. I'm very proud of Colorado for passing new stringent regulations, but other states haven't followed it. Further, the SDWA is being administered by state agencies in 34 states already for other industries so this wouldn't be an additional burden."

Research and Markets: Chinese Hydraulic Components Markets

2009-05-17T04:34:00.000-07:00

Research and Markets (http://www.researchandmarkets.com/research/e7bb4c/chinese_hydraulic) has announced the addition of Frost & Sullivan's new report "Chinese Hydraulic Components Markets" to their offering.

Construction Sector Does Some Heavy Lifting in the Chinese Hydraulic Components Market

The global economic downturn has had far-reaching effects across regions and markets but the Chinese hydraulic components market has managed to stay buoyant because of the demand from construction and industrial machinery sectors. The active real estate market and construction boom will help sustain this trend, especially with the 2010 World Exposition expected to stimulate greater construction activities. Moreover, relief work in the aftermath of natural disasters necessitate numerous excavators, loaders, bulldozers, cranes, and many other heavy construction machinery in which hydraulic components are key parts. Apart from construction, hydraulics components will find application in agricultural and farming machinery. Increased defense budgets due to the need for advancements in aircraft and fighter planes are also aiding the growth of the hydraulics component market. Additionally, the escalating investments in marine and processing industries bode well for market vendors.

The market will be gladdened by the increasing migration of manufacturing to China, since the relative low labor and material costs in the country are huge attractions for manufacturers. However, only the lower-end hydraulic components production is shifting to China, reducing the quantum of benefit. The country is a hot destination for manufacturers from other industries as well and they are not fighting shy of making heavy investments. "Due to the expanding hydraulic components market and the appreciation of Renminbi (RMB) to the U.S. dollar, many foreign investors will further increase their investment in China by setting up more sales offices and enhancing R&D budget," says the analyst of this research. "Foreign participants are expected to overwhelm the Chinese market and maintain their growth trend to increase the revenues and to raise the overall technology expertise of the Chinese hydraulic components manufacturers."

Manufacturers are hoping to pique end-user curiosity by launching many hydraulic-related projects. The flip side of building up such interest is that end users begin to have greater requirements, which tests medium- and small-sized manufacturers. Meanwhile, cost control is fast becoming a challenge due to the intensifying price wars between domestic and foreign manufacturers. "Nevertheless, with new materials and better hydraulic fluids being adopted in production, cost cutting and extended life cycle seem possible," notes the analyst. "Owing to the advanced technology, hydraulic components can better fit into the working environment and reduce the cost of installation and maintenance." The cylinder segment is the most affected by the improved technology and lower costs of domestic products. Greater demand for localization has had large companies expand their product range and indulge in mergers and acquisitions. They have also been establishing more direct trade offices in China to widen their coverage and offer better after-sales service.

This Frost & Sullivan research service titled Chinese Hydraulic Components Markets provides total market size, market and technology trend, and market segment revenue breakdown. In this research, Frost & Sullivan's expert analysts thoroughly examine the following markets: cylinders, valves, pumps, motors, and others.

Key Topics Covered:

-Chapter 2 Total Hydraulic Components Market: Impact of the Primary Challenges (China), 2007-2014

-Chapter 3 Total Hydraulic Cylinders Market: Market Drivers Ranked in Order of Impact (China), 2007-2014

-Chapter 4 Total Hydraulic Valves Market: Market Drivers Ranked in Order of Impact (China), 2007-2014

Parker to show hydraulic filtration solutions

2009-05-02T22:12:00.000-07:00

Parker Hannifin, a provider of motion and control technologies, will show three hydraulic filtration products at Hannover Messe 2009 on 20-24 April.

According to the company, the products, which have been developed considering environmental matters, simplify the filtration process and integrate filtration solutions into hydraulic system assemblies.

At 414bar maximum working pressure and flow options up to 700 litres per minute, the World Pressure Filter (WPF) series incorporates eco-intelligent performance media that are intended to reduce disposal waste and cost by more than 50 per cent.

Parker Filtration offers hydraulic system designers the possibility to integrate various system functions into single components.

This can result in cost reductions for the application in manufacturing and end-user maintenance and can realise more compact solutions and lower environmental impact by reducing leak points, for example.

Integrating high-pressure filters such as the WPF with quality media and patented elements is intended to guarantee the quality of filter performance and to maximise system component protection.

The filtration media has been designed in a patent-protected element range, whose element design is claimed to reduce time to change and eliminate oil spillage during changeover as the element remains in the bowl when removed from the filter head.

The bowl of the WPF filter can be quickly removed as no tools are necessary and the integral element requires the minimum of space for removal, allowing the filter envelope to be kept to a minimum.

The WDPF high-pressure duplex filters include a solution to allow remote switching.

Instead of the manual operation of the main duplex valve and equalising line, Parker's hydraulic solenoid valve technology makes a safe and remote operation possible with the WDPF filter.

This process can be fully automated; when one filter element gets contaminated, the filter condition indicator provides a signal to the duplex valve unit for direct switching to the other filter with a new element.

At the same time, a warning signal is provided to the local overall system controller that one filter element requires replacement.

In general, before switching the duplex valve, an equalising line needs to be activated to avoid excessive pressure peaks when putting the unused filter element into operation.

This solution overcomes the risk of the traditional manual process where correct usage of the equalising line is not guaranteed, according to the company.

Excessive pressure peaks can result in the damage of system components and seals, causing unexpected standstill and maintenance to process equipment.

By using Parker's patented filter elements, the quality of filtration is also safeguarded.

Another solution that will be on show is the company's Icount Mini-Lab, which eliminates the need for laboratory sample testing.

The Icount Mini-Lab has been developed to remove the engineer's reliance on external laboratory services for accurate solid particle contamination analysis of liquids.

Consisting of an Icount bottler sampler (IBS), a laptop computer containing the Parker analysis software with a printer and all the necessary cables mounted in a transportable trolley, the Icount Mini-Lab provides similar accuracy to the sampling carried out in a professional laboratory.

Each device is supplied with 30 Parker oil sample bottles and provides a way for both original equipment manufacturers and end users to monitor contamination in their fluid systems on site.

Testing is carried out in three steps: a hydraulic fluid sample is obtained from the system to be tested; the fluid is sampled for three minutes in the IBS; and the analysis report is printed out immediately.

A three-minute test is normally enough to confirm how contaminated the sample of hydraulic oil is.

The IBS provides onboard, laser-based, particle-counting technology, a three-minute maximum test and an oil contamination report programme in one system.

It features an interactive touch screen, a pressurised bottle chamber via an internal compressor pump, a bottle cavity aperture design, a sample tube cleaning sleeve minimising contamination crossover and an internal printer.

The Icount Mini-Lab is an onsite contamination monitoring solution for engineers and maintenance personnel and provides reproducible results performance to ISO4409:1999 and NAS1638 particle count distributions.

Installing a RAM Clutches Hydraulic Clutch Release - Moment Of Release

2009-04-24T22:51:00.000-07:00

With the introduction of the sporty '05 Mustang came something Mustang fans weren't used to-a hydraulic-clutch mechanism. Rather than having a cable connected between the clutch pedal and the fork to release the clutch disc for shifting, the S197 uses hydraulic fluid. This makes the clutch silky smooth but can cause problems in high-performance applications. So, we'll ask, is your transmission grinding and hard to shift under aggressive driving situations? If so, the transmission in your modified S197 Mustang probably isn't broken; it may be in the clutch setup instead.

We wanted to throw that out there because there have been a lot of misdiagnosed transmission problems lately. There's an epidemic in the growing S197 community-grinding gears that are hard to engage and disengage. In our search for a solution, we spoke to Justin Burcham of JPC Racing. "Everybody thinks it's a problem with the clutch or the transmission," he says. "It's actually a problem with the hydraulic clutch-release bearing, which will eventually lead to transmission problems. Ultimately, the synchro rings get beat up." Unfortunately, there's no way of knowing how many cars experience this problem.

RAM Clutches produces a heavy-duty hydraulic clutch release bearing. The piston and cylinder are hard-coated for protection.

The grinding and difficult shifting is due to the hydraulic clutch bearing that's used to control the clutch application (either in or out). The pedal isn't connected mechanically as in previous generations of Mustangs, which utilized a cable that connects the clutch pedal to a fork inside the bellhousing. The new cars feature a hydraulic unit that Ford engineers designed to make the Mustangs easier to drive. Much like the brakes, fluid is used to activate a mechanisim; in this case, the throwout bearing that presses on the pressure plate to control release and engagement of the clutch disc (or discs in a multidisc setup).

Since a clutch upgrade is a popular modification, many S197 Mustangs now have an aftermarket unit. Poor performance can result due to the OEM hydraulic clutch release system. "The car will shift fine under normal driving conditions, and the driver won't notice the issue until the engine is at a high rpm, or when racing or beating on the car," Burcham says. "When the driver goes to put it in gear or shift aggressively, the transmission will grind and, at times, not let the shifter go into gear because the clutch is still engaged.

It also features longer travel than stock: 0.510-0.525 inches compared to the stock setup's 0.430-0.450 inches. RAM says this unit is adjustable and compatible with any single- or dual-disc clutch system.

"The factory release bearing was designed for the OEM pressure plate. When you add an aftermarket clutch, there's an increase in centrifugal clamping force on the pressure plate in order for the clutch to attain a greater holding capacity. Thus, the spring that holds the clutch is stiffer, and in turn, the factory release bearing can't deal with the increased load."

According to Mike Norcia of RAM Clutches, the static clamping pressure of the clutch (at idle and low rpm) isn't that much greater than the stock one. The RAM 11-inch clutch has 2,400 pounds of pressure compared to the stock 11.5-inch unit's 2,250. As the rpm increases, however, the centrifugal force from the levers pushes the pressure-plate ring down harder. This is where the extra grip comes from, in addition to the better clutch disc material. Norcia adds, "The position of the lever in relation to the centerline of its mounting point (called the plane of rotation) is such that the upward angle promotes the lever forcing itself outwards as rpm increases. In addition, the centrifugal pressure isn't linear. It starts out shallow, around 5,000 rpm, and basically goes up by the square of the engine rpm from there. At 7,000 rpm, the pressure curve is at about a 45-degree relative angle. At 10,000 rpm, the line would be shooting almost straight up."

Hydraulic motors limit workplace noise

2009-04-18T00:04:00.000-07:00

Noise levels below 58dBA are achievable by using helical gear pumps and compact AC motors.

The Disability Discrimination Act 2005 is putting hydraulic through-floor lifts and step lifts in close proximity to people sleeping and working.

Often the hydraulic noise and vibration levels can be unacceptable, the sources of which are generally the hydraulic pump and motor.

The only solution to date being to house the hydraulics in expensive enclosures.

Hydraproducts new mini hydraulic power pack range has been designed specifically for use in low noise passenger and mobility lifts.

Noise levels below 58dBA are achievable, based on ISO4412 testing, by using helical gear pumps and compact AC motors.

Continuous-contact helical gear pumps minimise pressure ripple, give high efficiencies and quiet operation.

Flow rates are from 8 to 19 litres a minute and continuous pressures up to 275bar Compact AC motors up to 0.75kW have a single-piece body with precision roller bearings.

This gives a smooth drive to the pump, reducing mechanical noise production.

Single acting valves with a low-pressure drop have a diffusing "labyrinth" fitted to ensure smooth lowering minimising aeration, which can cause pump pulsation.

The overall reduction in noise and vibration increases efficiency and life of the hydraulic system.

Sensor handles tough hydraulic applications

2009-04-03T01:00:00.000-07:00

The new Gefran RK series position transducer uses a contactless magnetostrictive linear sensor for accurate and reliable displacement measurement in hydraulic applications.

The Gefran RK position transducer uses a contactless magnetostrictive linear sensor for accurate and reliable displacement measurement in hydraulic applications.

The RK series is designed for OEM use within hydraulic cylinders, typically for monitoring and control in mobile applications such as earth moving, agricultural and mining equipment.

Suitable for cylinder stroke lengths from 50 to 4000mm, the compact sensor has a 10mm diameter probe, with a compact, versatile head arrangement.

External connection to the head is via an IP67-rated cable connection that is up to 50m long, providing a straightforward analogue output of displacement, with linearity and accuracy of better than 0.02% of full-scale.

The robust and durable transducer relies on the interaction between a magnet on the moving piston and the magnetostrictive transducer rod element.

This enables noncontact, solid state position measurement that is not subject to mechanical wear, tolerates working temperatures up to 90C, with 20G vibration and 100G shock and is sealed against the hydraulic environment for working pressures up to 700bar.

The RK series transducer provides a direct analogue voltage output (0-10V) proportional to position, using a standard 18-30V DC power supply.

A 12V powered unit is also available, which provides an analogue 0-5V output.

The magnetostrictive timing pulses from the transducer can also be monitored by the Gefran EK series remote electronics module.

This module offers CANopen and other digital interfaces, transmitting digital position and speed of movement measurement information (up to 10m/s) to the equipment control system.

The EK series modules are also capable of monitoring the position of two or more magnets operating on the same magnetostrictive transducer rod element.

XYZ hydraulic surface grinder bought by MHV

2009-03-25T08:59:00.000-07:00

MHV Products has bought a surface grinder from XYZ Machine Tools to fulfil its requirement for a relatively large table on a compact machine.

The order that prompted the installation of the XYZ 1224 hydraulic surface grinder involved the machining of 2in-thick steel plates 700mm long by 300mm wide.

XYZ surface grinder has useful larger table

Machining had to be extremely accurate in terms of final thickness and parallelism as the plates were intended for machines that punch the centre holes in 'master' CDs.

However, they were too big to grind on the company's existing surface grinder.

The initial solution involved outsourcing the surface-grinding operation, but this resulted in turnaround times of anything up to three weeks.

The alternative was to invest in a surface grinder with a larger table, although with only a limited demand for surface grinding, Kevin Hibbert, director and owner of MHV Products, opted for a manual machine rather than one equipped with a digital readout or CNC system.

The XYZ 1224 fitted the bill, especially as it has a footprint of 3550 x 2550mm and is supplied as standard with a permanent or electromagnetic chuck, dust extraction and flood coolant, as well as power rise and fall to the wheelhead.

Available options include automatic incremental downfeed, overhead wheel dresser and digital readout.

Software upgrade eases hydraulic design

2009-03-17T08:26:00.000-07:00

Hydraulic and electrical designs are integrated through a combined design platform that has the flexibility to customise views to select only essential electrical design information.

Zuken has released the 2008 version of the dedicated fluid design module of the E3.series environment.

The new version makes the design of hydraulics and pneumatics a more cohesive part of the design process.

Hydraulics design engineers benefit from the best of both the individual and collective approaches to design.

Hydraulic and electrical designs are integrated through a combined design platform that has the flexibility to customise views to select only essential electrical design information, eliminating the unnecessary burden of irrelevant electrical complexity within the design view.

In addition, both hydraulics and electrical designers can now work within E3.series simultaneously, enabling them to work more collaboratively while improving quality and reducing development cycles.

Now fully integrated with electrical systems, the customised platform provides hydraulics engineers with a dedicated design environment complete with the ability to define their own symbols, such as tubes and hoses.

Hydraulic and pneumatic sheets are on display in the project tree and likewise, specific components appear in the components trees.

Customised views allow all users to select the level of detail of either the hydraulic or electrical data in the design view they are working on.

This is powered by the E3.enterprise edition, which enables concurrent design in a multiuser environment.

In the 2008 version, many of the advancements also have a direct advantage for the E3.fluid user.

It has improved functionality for quickly managing product variants and options and the ability to embed any file for improved project management.

BASF Expands Line with Biodegradable Hydraulic Fluid

2009-02-27T17:29:00.000-08:00

BASF Corporation is expanding its portfolio of low toxicity and biodegradable hydraulic fluids with the introduction of Plurasafe H2O-K hydraulic fluid, a new product designed for equipment used in marine and water-sensitive applications.

"High heat and pressure can cause many types of equipment to leak hydraulic fluids into the environment," said Rebecca Hollis, business manager of performance chemicals for BASF in North America. "This is especially true in marine applications, including boats and dock operations, where hydraulic leaks can affect oceans, lakes, rivers and streams."

Plurasafe H2O-K fluid is a proprietary product that is designed to protect the entire hydraulic system against wear and corrosion damage. This unique formulation has low aquatic toxicity and is readily biodegradable.

Applications for Plurasafe H2O-K hydraulic fluid can include recreational and commercial boat hydraulic systems, marine and commercial dock operations, industrial and commercial truck hydraulic systems, carwash systems, environmentally sensitive hydraulic systems, and industrial machinery.

Hydraulic fluid leaked into river from hospital elevator

2009-02-10T03:37:00.000-08:00

A spill at UT Medical Center sent up to 85 gallons of elevator hydraulic fluid into the Tennessee River.

The spill happened Saturday. Hydraulic fluid leaked from an elevator shaft into a drain, which empties straight into the river.

UT Medical Center said it found out about the spill late Monday morning, when a company on contract to repair the elevator notified the hospital.

The company called 911 Monday, said it was a non-emergency call, and notified the Knoxville Fire Department of the spill.

UT said, of the 110 gallons that leaked out, 25 gallons were pumped and recovered.

The drain from the elevator shaft runs straight to the river. UT Medical Center said the elevator and its housing were built to the existing codes in the mid 1980s.

UT Medical Center said it is working diligently on further cleanup efforts, and its hazardous response contractor expects full containment by Tuesday morning.

The Knoxville Fire Department said the fluid was in the river and gone, preventing cleanup of what was already in the water.

Latham Marine Develops New Hydraulic Lift System

2009-02-04T08:32:00.000-08:00

FORT LAUDERDALE, Fla. - (Business Wire) Latham Marine, a company that built its reputation with its hydraulic steering system and top-quality parts for the performance boat segment, is further expanding its line with a new hydraulic lift system. The lift will debut at the Miami International Boat Show, February 12-16, 2009 at the company’s new booth, # H80, at the Miami Beach Convention Center.

While Latham Marine has manufactured patented hydraulic lifts for Thunderbird (Formula) Marine for over five years, the new system was created for another customer’s 47’ sport yacht under development. The lift’s 4-bar linkage system with a port-less ram is unique, as it encloses all the hoses and fittings within the cylinder, making it corrosion- resistant and minimizing the chances of a hydraulic fluid leak. The stainless steel system is machined and built in-house to Latham’s standards for strength.

Bob Latham, president of the company, has specialized in engineering problem-solving systems for over 35 years and brought his intuitive talents to the new lift project. He and his team devised a weight-specific, integral mechanical lock that secures the cylinder in the “up” position; the lock provides back-up security and strength as boat owners seek to safely and smoothly move watercraft and dinghies aboard onto swim platforms.

“We saw other systems on the market as flawed,” said Latham. “Our commitment is to ‘over-engineer’ to make sure that our parts and systems work impeccably. We ensure that we exceed our customers’ expectations.”

In addition to the lift, Latham Marine will display its aluminum sea pump (debuted last year in brass), to accommodate smaller, lighter boats. The sea pump is important in avoiding engine over-heating and Latham’s self-priming pump was a popular addition to the company’s extensive line of OEM and after-market parts.

Latham Marine hand-crafts and machines all its parts in its Fort Lauderdale factory, where quality control and customer service are priorities. “I build every part as if it was going on my boat,” he states.

ESCO Hydraulic Coupler

2009-01-18T06:33:00.001-08:00

ESCO Corporation's new TwinLock™ Hydraulic Coupler can pick up a full range of OEM buckets within a machine's weight class.

The new coupler is designed for improved performance and safety. It has a cast body for performance and increased life over fabricated couplers. The design includes two key locking features that increase safety. The front latch acts as the first locking mechanism and is visible to the machine operator. The second locking mechanism is two gravity-operated mechanical locks that secure the attachment in the event that hydraulic pressure is lost.

Other benefits: The Coupler can be operated directly from the machine's cab without need for the operator to manually insert a pin; front latch serves as a backup locking mechanism and a visual indicator when the hydraulic cylinder has retracted; front retaining jaw catches the front pin in the event the hook is not fully engaged on the attachment pin, ensuring attachment retention; cast couplers are available for 7- to 40-ton excavators, with increased strength and less weight at the end of the stick than with fabricated couplers.

Hydraulic Boat Lifts

2009-01-18T06:32:00.001-08:00

Among a variety of technologically advanced and mechanically upgraded boatlifts, hydraulic boatlifts deserve special mention. In the search for protection that's tough on waves - but easy on the environment and community aesthetics - many have found a solution in floating wave attenuators.

Most hydraulic boatlifts are standard with non-corrosive stainless steel bolts, stainless cable and brass nuts, giving you many years of service while maintaining a clean appearance. Thick urethane sheaves are used to maximize cable life and to ensure lasting performance under heavy use. Most of the hydraulic vertical lifts offer rigid diagonal V-bracing on both sides, giving uncompromised strength on demand when your boat is raised to maximum height. There are a number of companies who offer a variety of hydraulic boats ready to give these pleasures and advantages. Certain characteristics and features of hydraulic should be highlighted:

The hydraulic cylinder is enclosed in a beam assembly. Stainless bolts, pins, and brass nuts are used on all lifts and accessories to provide years of reliable service. The hydraulic pump, motor, and battery are enclosed in a poly box that can be locked to protect your investment.

The hydraulic lift comes standard with a two-button remote for raising and lowering the lift. Additional remotes are available and are easy to program to each specific unit.

No matter which kind of hydraulic boatlift you choose, see if you can get a one-year warranty, or an even longer one if possible. That way, if it ever breaks down, you won't end up throwing away even more money than you spent in the first place. A boatlift is meant to save you money on repairing your boat; it should never become an ongoing expense unto itself.

Boat Lifts provides detailed information on boat lifts, used boat lifts, floating boat lifts, boat lift motors and more. Boat Lifts is affiliated with Boat Docks.
