What is the problem of jaws of life?
Jaws of Life Cause Serious Injury The jaws of life have a motor linked by two pipes through which hydraulic liquid is pumped. There had been a problem with this equipment approximately one week before Mr S’s accident but it would appear that the repair had not been carried out in a correct fashion.
How powerful are the jaws of life?
High pressure means high performance. The 10,000 PSI line of tools includes the strongest cutter manufactured today: the S 700. Plus, these high-pressure rescue tools are built a bit lighter and are faster to the point of resistance.
Why are hydraulic systems used?
Hydraulic systems are mainly used where a high power density is needed or load requirements chance rapidly. This is especially the case in all kinds of mobile equipment such as excavators and in industrial systems such as presses. In wind turbines, hydraulics is used for pitch and brake control.
What does extracted with Jaws of Life mean?
The jaws of life is a term that refers to many hydraulic rescue tools used by emergency response crews in order to extricate an accident victim from the wreckage of a rollover, car crash, or other vehicular accident.
Who invented jaws of life?
George Hurst
How much does jaws of life weigh?
48.1 pounds
What is a hydraulic cutter?
What is a hydraulic cutter? Hydraulic cutters are the biggest, meanest, sharpest pair of shears you have even seen. They have metal blades (often made of hard steel) that can cut through even the most difficult metals.
How do hydraulics works?
Hydraulic systems work by using pressurized fluid to power an engine. These hydraulic presses put pressure on a small amount of fluid in order to generate a large amount of power. That pressure forces it against a piston on the other side of the container.
What are the specifications of the jaws of life?
Spreading force: up to 57,550 lbs (256 kN). Pulling force: up to 11,500 lbs (51 kN). Spreading distance: 28.3″ (720 mm). Weight 43.2 lbs (19.6 kg)….Technical Specification.

Why was the Jaws of Life invented?
The jaws of life tool was originally developed by Hurst in the 1960s to rescue drivers in crashes at the Indianapolis Motor Speedway and then adopted by rescue agencies throughout the country, Lamerel said.
How do you remove air from a closed hydraulic system?
For dissolved air, you can remove it by raising the temperature of the fluid until the air is released. This should only be done if absolutely necessary as hydraulic oil will normally tend to be at least 10% dissolved air.
What is the difference between hydraulics and pneumatics?
Both pneumatics and hydraulics are applications of fluid power. Pneumatics use an easily compressible gas such as air or other sorts of suitable pure gas—while hydraulics uses relatively incompressible liquid media such as hydraulic or mineral oil, ethylene glycol, water, or high temperature fire-resistant fluids.
During what decade was hydraulic power first used for farming?
The Ferguson three-point hitch system was the first agricultural use of a technology that was predicted centuries ago and developed for other industries in the 1700s – hydraulic power.
What are the Jaws of Life actually called?
The term “Jaws of Life” refers to several types of piston-rod hydraulic tools known as cutters, spreaders and rams that are used to pry open vehicles involved in accidents when a victim may be trapped.
What do firefighters call the Jaws of Life?
