What are the different types of jaws of life?
Types of Jaws of Life The Jaws of Life has four main types of hydraulic rescue tools: spreaders, cutters, rams and combination tools.
What are the materials used to make the jaws of life?
Cutters typically have an aluminum-alloy housing with forged, heat-treated steel blades. The piston and piston rod are often made of heat-treated alloy steel. The cutters are used to cut or shear through materials such as sheet metal and plastic.

How is the Jaws of Life used?
The ‘jaws of life’ are a hydraulic-extrication rescue tool used in a number of difficult emergency situations, particularly car crashes. It is most often used to pull drivers and passengers out of damaged vehicles after severe traffic collisions.
Who is the first person that invented the Jaws of Life?
REDLANDS, Calif. (AP) _ George Hurst, inventor of the widely used ″jaws of life″ rescue device and four-speed transmission pioneer, has been found dead in his garage, authorities said Thursday.
Who uses jaws of life and why?
The Jaws of Life has been used in thousands of emergency situations to assist firefighters. The machines are hydraulic tools also known as cutters, spreaders and rams that are used to pry open vehicles in accidents in which a victim may be trapped.
How many lives have the jaws of life saved?
24,000 Lives
What does the jaws of life mean?

What does the phrase the jaws of death mean?
: dying or being killed He barely escaped from the jaws of death.
What mean Jaws?
noun. either of two bones, the mandible or maxilla, forming the framework of the mouth. the part of the face covering these bones, the mouth, or the mouth parts collectively: My jaw is swollen.
What is the meaning of hydraulic?

What is hydraulic stress?
Hydraulic stress is the measure of the internal force per unit area acting on the liquids. Hydraulic Stress is the restoring force per unit area when the force is applied by the fluid on the body. In the case of liquids to the hydraulic stress is defined in the same way.
What is the purpose of hydraulics?
Remember, the purpose of hydraulic systems is to create motion or force. It’s a power source, generating energy. Don’t underestimate hydraulic energy in your safety program. It is small but mighty in force.
What are the 5 basic components of a hydraulic system?
The primary components of the “plumbing” portion of the hydraulic system include the following:
- Reservoir.
- Filters.
- Shut Off Valves.
- Control Valves.
- Pressure Relief Valve.
- Hydraulic Fuses.
- Accumulators.
How are hydraulics so powerful?
Hydraulics work because you can’t make liquid smaller. So you can push a little bit of liquid a long ways into a tube, or you can push a lot of liquid a little way, and everything will be at the same pressure. Same pressure and more area means more force. Perhaps the easiest way to visualize this is with many tubes.
Which fluid is used in hydraulic lift?
A hydraulic fluid or hydraulic liquid is the medium by which power is transferred in hydraulic machinery. Common hydraulic fluids are based on mineral oil or water.
Which is thicker AW32 or AW46?
Which is thicker aw32 or aw46? AW32 is a little lighter than AW46. I would use the lighter weight if I was using it mainly in winter and the heavier if I was using it mainly in summer.
Which hydraulic oil is thicker 32 or 46?
The hotter the temperature, the thinner the oil becomes and the colder the oil, the thicker. So, for example, a hydraulic system operating in a cold climate like Tasmania would run better with a lower viscosity grade of 32. Here in Perth, 46 and 68 are better suited to our climate.
Can I mix AW32 and AW46?
Yes the numbers are the viscosity grades and in your case you are intenting to top up, and you can be sure that if the same brand and poduct type are mixed will not give any adverse reaction. even if you top up 50% of the capacity the viscosity would still be at around 38- 39 CST and should not be a problem.
Is AW 32 the same as 10w?
Your local tractor supply store handed you the correct viscosity. SAE 10 weight is equivalent to ISO 32.
Is VG 46 the same as AW 46?
AW 46 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 46. This is the thickness of the fluid tested at 40 degrees Celsius. ISO VG 46 is the most popular grade due to its middle grade flow properties with a thickness that is equivalent to a SAE 15 weight lubricant.
Is AW 46 hydraulic oil the same as ISO 46?
ISO 46 simply refers to the vicosity. AW stands for “Anti Wear”. Your AW Hydraulic Oil ISO 46 is going to be the same thing as AW-46. It’s just that the words are rearranged in a different order.
What does ISO VG 46 mean?
Determining the viscosity number Viscosity is defined as a fluid’s resistance to flow at a specific temperature. For example, for a lubricant to be considered an ISO VG “46,” it would have to have a flow speed of 41.4-50.6 cSt. The thicker the oil (the slower the flow rate) gives it a higher ISO VG number.
What is the viscosity of AW 46 hydraulic oil?
46 cSt
What is the difference between ISO 46 and ISO 68 hydraulic oil?
ISO 46 Hydraulic Oil – ISO VG 46 Hydraulic Fluid is normally required for industrial plant working under high-pressure etc. ISO 68 Hydraulic Oil – ISO VG 68 Hydraulic Fluid is designed for use in systems which require a large load-carrying ability.
Is 10W 30 the same as SAE 30?
Nope. SAE 10W30 is an oil that has SAE 10W viscosity(thickness) at low temperatures, and SAE 30 viscosity at high temperatures. In theory, they’re the same at high temperature, which is IIRC set at 100C. An engine at operating temperature has its oil temp somehwere around that temperature.
What does 10w40 mean?
In a 10w-40 for example the 10w bit (W = winter, not weight or watt or anything else for that matter) simply means that the oil must have a certain maximum viscosity/flow at low temperature. The lower the “W” number the better the oil’s cold temperature/cold start performance.
What oil is comparable to sae30?
Obviously, SAE and ISO use two different scales to measure viscosity. SAE 10W is equivalent to ISO 32, SAE 20 is equivalent to ISO 46 and 68, and SAE 30 is equivalent to ISO 100.
