Eaton Announces Breakthrough in Hydraulic Hose Technology

Diversified industrial manufacturer Eaton Corporation today announced the launch of a new breakthrough technology that enables reporting of imminent hose assembly failure by means of real-time monitoring of high pressure hose assemblies used in hydraulic systems.

Eaton's LifeSense(TM) hose, a patented hydraulic hose condition monitoring system, will be introduced to the North American market at the International Fluid Power Exposition (held in conjunction with ConExpo 2011) in Las Vegas, March 22 - 26, and to the European market at Hannover Messe 2011 in Hannover, Germany, April 4 - 8.

Eaton's LifeSense hose was developed in conjunction with Purdue University and the Purdue Research Foundation's Office of Technology Commercialization to continuously monitor the health of hydraulic hose assemblies and alert users when an assembly approaches the end of its useful life. The LifeSense hose can monitor and track the health of each hose assembly in a hydraulic system. This system does not estimate or predict through arithmetic calculations when a hose is going to fail, like some products on the market today. The LifeSense hose actually detects when a hose is nearing the end of its useful life. Then an alert is sent to the user so that the assembly can be replaced to prevent downtime. A single monitoring unit can handle input from multiple hose assemblies.

"Most hydraulic maintenance programs are designed to avoid hose failures by replacing assemblies at regular intervals, using a schedule based on usage data or past experience," said Doug Jahnke, Eaton product marketing manager. "As a result, a large number of perfectly good hydraulic hose assemblies are discarded long before the end of their useful life out of fear that they might fail."

The LifeSense hose allows the user to utilize virtually all of the useful life of a hydraulic hose assembly, more than 50 percent longer life in a typical lab test, thus saving on replacement costs and associated downtime while providing peace-of-mind that productivity will not be impeded and safety not compromised by unpredicted hose failure.

"Additionally, hydraulic hose failure is one of the largest causes of unplanned maintenance events," Jahnke said. "Hose failures in the field present serious safety issues, environmental concerns and result in unscheduled system downtime, all of which have serious economic impacts."

The initial LifeSense hose offering will include the widely-used -8, -12 and -16 two-wire hose assemblies. Eaton's LifeSense hydraulic hose condition monitoring offers performance equal to industry standard 2SN pressure-rated hose and is certified to the same industry specifications as conventional hydraulic hose products. The technology is currently available for trial with factory-made assemblies including straight JIC swivel fittings.

Off-duty nurse helps save two people trapped after car smash

The two injured teenagers suffered through a long ordeal trapped in a car after it smashed into a pole in Ballarat.

Four people were on board when the accident happened in Humffray Street South, Golden Point, about 8.15pm.

But the female driver, 18, and a man in the front passenger seat were trapped from the waist down.

Sen-Sergeant Patrick Clearly told Radio 3AW all four were lucky to survive, as a result of the "quick action of passers-by", including the off-duty nurse.

"She actually got into the back of the car, while it was burning and shielded the faces of two trapped … while another neighbour used a garden hose to put the fire out."

Ambulance Victoria spokesman John Mullen said Both were given pain relief and remained conscious while emergency crews worked to free them.

Mr Mullen said the pole, which had snapped off and was resting on the car, had to be stabilised with a crane before the rescue began.

"The force of the impact had pushed the front seat right to the back of the car," he said.

Mr Mullen said the front seat passenger, also believed to be about 18, was trapped for almost five hours.

"He had 'crush injuries' – leg, pelvic – after also being trapped from the waist down," Mr Mullen said.

"He was put into an induced coma and he was flown to the Alfred hospital in a serious but stable condition."

Mr Mullen said the driver was trapped for almost two hours before being flown to the Royal Melbourne Hospital in a stable condition.

"She was treated for leg injuries and possible spinal injuries," he said.

CFA spokesman George Ellis said crews used hydraulic cutters to remove the pair.

"The last person was removed from the car at 12.40am," he said.

A police spokeswoman said officers were investigating the smash.

"It’s believed a Holden sedan was travelling along Humffray Street South when it lost control and struck a power pole," she said.

"The vehicle caught fire but was extinguished."

Two other people on board were taken to Ballarat Base Hospital with minor injuries.

Compressed Gas Equals a Bomb

Construction work often requires the use of tools powered by compressors. Both pneumatic tools and hydraulic machines use compressors as their source of energy.

By definition, a compressor is a mechanical device that is used to increase the pressure of a gas/liquid by reducing its volume in order to concentrate it under high pressure.

Compressors work in a similar way to pumps as they both increase the pressure on a fluid and both can transport the fluid through a high pressure pipe.

Compressors can also be used to transmit pressure from one point to another through oil fluids in high pressure pipes.

At construction sites, compressors are used to provide power for many of the tools and utilities used by workers, such as jack hammers, pneumatic hammers and some types of rock drills.

Air compressors and gas compressors are the most common type used in construction sites. Their use is accompanied by certain risks to workers. The major risks presented by compressors are:

Explosion of compressed fluids from weak high pressure pipes, which can cause burns, blindness and deafness to those in the vicinity.

Hose whip effect that results when a hose pipe is disconnected while still containing fluid under high pressure. This can hit a worker, damage equipment and even kill.

Fire from ignited fuel tanks that may result from the overheating of the compressor engine.

Debris flying at high speed when the compressor is used in cleaning works can cause grievous injuries.

Emissions of large amounts of dust during cleaning can cause breathing-related complications

The individual power tools each present their own kind of hazards, complicating the control measures that need to be put in place when operating a compressor.

Compressed air is a very dynamic and powerful source of energy. Most site compressors have the capacity to deliver enough pressure to send debris flying at speeds capable of penetrating human skin.

A simple activity such as cleaning oneself using a jet of compressed air can cause permanent injury and death. It is possible for compressed air to burst an eardrum, blow out an eyeball or penetrate the skin, injecting air into the bloodstream. Pointing compressed air at anyone for any reason can be extremely dangerous as the high pressure jet can cause blindness and even burst eardrums when applied directly.

Never adjust blow off or control valves without referring to the operation manuals as improper adjustments can cause air explosions from the safety valve, startling and even injuring experienced operators.

To control the risks associated with the operation of compressors and pneumatic power tools, the following measures should be put in place:

Read the operator's manual and be sure you understand it before using the equipment.

Never allow anyone to ride on top of the compressor machine when towing.

Make sure that all guards and shields are in place and in good working order.

Use the proper respirators for the job as most air tools create a lot of dust during operation.

Only use hose pipes that have been fully rated for the power output of the machine.

Protect the hose at all times as it presents a tripping hazard. It should also be kept out of the way so as not to be accidentally damaged by the tool being used.

Never use a hose that shows signs of damage.

Wear a helmet, hard toed boots, safety goggles and ear muffs during operations.

Wear protective gloves when using a rock drill, a paving breaker and a tamper but do not use gloves when using impact tools such as pneumatic hammers and impact wrenches to avoid the equipment from slipping out of your grip.

Fire wins Battle of Badges blood drive

A Memorandum of Understanding was signed between the McPherson County City
Continued from 1
mission and Heart 2 Heart Child Advocacy Center. The agreement offers Heart 2 Heart about 700 square feet of space in the McPherson Municipal Building at a monthly rate of $700, with utilities included. A similar offer has also been offered by the McPherson County Commission for space in the Bank of America building, although Mayor Tom Brown said the offer of his board was meant as an alternative and should not be viewed as competitive. Heart 2 Heart recently lost its existing lease and has been looking for options that would allow it to continue providing advocacy services to children in McPherson.

•In response to ongoing Environmental Code violations, the commission issued a 60-day notice to the owner of property at 501 E. Hancock. A previous notice to secure broken and otherwise open windows and doors on the property was not responded to, forcing the city to board up the openings themselves. Further notices are being or have previously been issued in reference to roof problems, dangerously low electrical lines, broken siding, an open and unsecured garage door, rotting sill plates, fallen privacy fencing, peeling paint, loose garbage and a dead tree trunk in need of removal. Should concerns not be tended to within 60 days, the property, which already has $9,000 due in penalties and back taxes, will be required to pay the city for repairs. The property has been recommended for condemnation by City Building Inspector John Puchosic and is in a deteriorated condition some 8 to 10 times worse than neighboring properties.

•The vacation of 350 feet of city property at the end of Maple Street was approved. Zoning Administrator Tom Stinemetze said “legally speaking, that piece of street has never actually existed,” referencing the Planning Department’s assertion it had never intended that area to be considered in the City of McPherson. But the city considers the property in its right-of-way. The vacation will be effective 30 days after its passing, unless a protest be submitted, requiring the issue be considered in a public hearing.

•The McPherson Board of Public Utilities  is considering replacing a stretch of water line running along First Street. The section, located between Grimes Street and McPherson High School, has suffered two breaks already this year, both within 50 feet of one another and each inflicting significant damage to road surfaces in the area. BPU will attempt to synchronize any such construction with road repairs to the street.
•A letter of engagement was issued by the commission with Standard and Poor’s. The letter allows the credit ratings agency to evaluate the merits of the utility’s credit standing. This will allow BPU to move forward in refinancing approximately $7 million in bonds.

•The commission issued a funding approval to the McPherson Fire Department for the purchase of new hydraulic hoses for its Jaws of Life device. The unit, purchased in 1994, was identified as having leaks in its hose during routine testing, and attempts to patch the leaks were unsuccessful. Up to $1,500 was approved for replacement hosing materials.
•An ordinance was approved designating proceeds from effluent water income to be initially deposited in the city’s general fund. Such income will later be transferred to the bonds and interest fund for payments on capital improvement projects, such as the $1 million drainage project of earlier this year.

•The appointment of Brent Christiansen to the McPherson Public Library’s Board of Directors was approved. Christiansen will fill the vacancy left by sitting board member David Harger, who is leaving the board during an unexpired term.
•Stinemetze informed the commission a public hearing will take place at 7:30 p.m. on Oct. 4 to consider the adoption of new subdivision regulations. The new regulations have been under development for almost three years.

•The State of Kansas has given the city permission to continue with floodplain modifications, providing a list of 15 specific restrictions which must be taken into consideration in the process. This will allow McPherson to proceed with modifications, which have been at a standstill pending permission to proceed from the state.
•In his weekly report, City Administrator Nick Gregory received approval for two bonds.

Garbage Trucks Pick Up Fuel Savings

Makers of hydraulic equipment are vying for some of the glamour and profit associated with green technology. They're starting with garbage trucks.

Eaton Corp. and Parker Hannifin Corp., both based in Cleveland, are pitching rival hydraulic systems designed to slash fuel consumption by refuse trucks, while reducing pollution and brake wear. And they are talking a bit of trash about each other's products. Bosch Rexroth, a unit of Germany's Robert Bosch GmbH, also has hopped on the garbage wagon.

The companies' systems can be built into vehicles made by such manufacturers as Volvo AB's Mack Trucks, Autocar LLC and Paccar Inc.'s Peterbilt.

The so-called hybrid-hydraulic technology makes use of the energy normally lost in the form of heat when drivers hit the brakes. Trucks equipped with it have two sources of power: the ordinary engine under the hood and a hydraulic contraption attached to the chassis.

When the driver brakes, hydraulic pumps push oil against a rubber-like "bladder" filled with nitrogen, creating pressure. When the truck accelerates, pressure is released, providing energy to turn the wheels.

The engine does less work, particularly during fuel-guzzling accelerations, when the hydraulic pumps kick in. Brakes get much less wear because the hydraulics help slow the truck.

The technology has been around for decades but is being rolled out now because fuel costs are up and modern electronics make it more effective. It works best on heavy vehicles that stop frequently, such as trash haulers, city buses and delivery trucks. The added cost wouldn't be worthwhile for passenger cars or long-haul trucks, some experts say.

The hybrid-hydraulic systems are competing with electric-hybrid technology, which uses the energy generated by braking to recharge a vehicle's battery. Hybrid-electric trucks, including delivery vans and buses, are far more common, with about 4,000 on U.S. roads, according to Bill Van Amburg, a senior vice president at Calstart Inc., a nonprofit group in Pasadena, Calif., that promotes fuel-saving technology. Hydraulics can produce a huge surge of energy quickly; batteries are better for releasing stored energy over a longer period.

Mack Trucks, a giant in the trash business, says it thinks electric hybrids—using technology from its parent, Volvo—have greater potential than hydraulics for cutting fuel use and emissions. But Mack installs hydraulic systems for clients who want them.

Parker Hannifin sees potential revenue from sales of hybrid-hydraulic systems of $300 million to $500 million a year within five years, up from a tiny sum today. Research firm Frost & Sullivan says that North American sales of garbage and other sorts of medium- and heavy-duty trucks with hybrid-hydraulic technology will reach 7,200 vehicles in 2016, up from 300 last year.

There are only about 115 garbage trucks with hybrid-hydraulic systems now operating in the U.S. But new registrations of garbage trucks have averaged nearly 7,000 annually in recent years, according to data provider R.L. Polk & Co. Hydraulic companies hope to capture a big share of those sales.

Eaton currently has about 100 of its systems in garbage trucks, Parker Hannifin 11 and Rexroth 34, mostly in Germany.

The hydraulic companies are taking different technological roads. Parker Hannifin's hydraulic system takes the place of a vehicle's transmission, so both the hydraulic pumps and the engine rely on a single mechanism to transmit energy to the wheels. Eaton and Rexroth have "parallel" systems, which use a separate transmission for the engine.

"Ours is like central air-conditioning," says Jeff Cullman, president of the hydraulics group at Parker Hannifin, "and theirs is like a window air-conditioning unit," bolted on to a more traditional structure.

Pine Street Tamaqua, 401-403 Pine St., Tamaqua, was cited for using or permitting the use of a loudspeaker where music or other entertainment could be heard outside Jan. 8.

All of these charges will be brought before an Administrative Law Judge, who has the authority to impose penalties ranging from $50 to $1,000 for minor offenses and up to $5,000 for more serious offenses.

In addition, the judge can also impose a license suspension or revocation based on the severity of the charge, or mandate training for the licensee in an effort to educate on the requirements of being a licensee in Pennsylvania.

2 injured in Route 895 crash

SUMMIT STATION - A Jonestown man and a Shillington woman suffered minor injuries in a motorcycle crash at 4:04 p.m. Monday on Route 895 at Manor Road.

State police at Schuylkill Haven said a 2010 Harley Davidson motorcycle driven by Walter R. Burns Jr., 65, of Jonestown, with passenger Gloria J. Urban, 67, of Shillington, was headed westbound on Route 895 nearing Manor Road when Burns was rounding a 90-degree right curve.

A piece of farm machinery that traveled through the area earlier and sprung a leak in a hydraulic hose had sprayed hydraulic oil on the roadway, troopers said.

The motorcycle hit the oil in mid-turn and slid off the roadway, troopers said.

Both passengers, wearing helmets, suffered scrapes and bruises on their left arms and legs and were treated at the scene, troopers said.

New Philly man faces charges

NEW PHILADELPHIA - Tori Wallace, 33, of New Philadelphia, was charged with harassment following an incident at 7:55 a.m. Tuesday in the area of Water Street and Federal Street.

State police at Frackville said Wallace and Vanessa Fisher, 37, of New Philadelphia, were dropping their children off at the bus stop when, after their children boarded the bus, Wallace attempted to confront Fisher by poking her and yelling at her.

Fisher ignored Wallace and walked back to her residence as Wallace threatened to harm her, troopers said.

Charges of harassment will be filed with Magisterial District Judge David A. Plachko, Port Carbon.

Tamaqua man hit by vehicle

TAMAQUA - Norman Mc-Laughlin told police he thought he could make it to his parked car in the 300 block of Pine Street, Route 309, in Tamaqua early Tuesday morning.

McLaughlin crossed the street but did not make it to his car and was struck by a tractor-trailer, police said. He struck his head on the pavement but was conscious, sitting up and talking to paramedics as they treated his head injury, according to a witness.

The accident occurred before 5:30 a.m. and backed up traffic for almost an hour on Route 309. Tamaqua police are continuing their investigation.
