It has the sharp jaws of the cutter and the moveable arms of the spreader.The spreader is used to pull pieces of the structure apart, or it can be inserted into the side of the vehicle to tear a section out. There is also a versatile “Jaws of Life” tool that is a spreader and a cutter combined together into one machine. It can also provide over fourteen thousand pounds of pulling force. Spreaders come in different sizes, too, but one certain size can provide sixteen thousand pounds of force. The spreader can also be used to tear wrecked vehicles or buildings apart. When the arms are opened by an emergency rescue worker, they spread the materials apart in order to create a larger opening. The arms are closed and then positioned into a small space. – arms that are used to separate parts of a wrecked vehicle or a toppled building. The emergency rescue worker who is operating the cutter can control the open and closed positions by changing the valve switch. When the piston is in the “up” position, the jaws open when the piston is in the “down” position, the jaws close. With the hydraulic – powered cutter, phosphate – ester oil is pumped into the cylinder of the cutter. It can easily cut through most of the materials that vehicles are manufactured with. A cutter has sharp, bladed jaws that open and close.

Cutters come in assorted sizes, and a cutter can be used to cut a roof, door, et cetera, off of a wrecked vehicle, for example, to free trapped victims. With added accessories, the ram can also be used to pull, instead of push.Ĭutters and spreaders can also be powered by hydraulics, electricity, and pneumatics. This can allow emergency rescue workers to reach trapped accident victims. For example, if the roof of a vehicle is wrecked and pushed in, a ram can be positioned so that it pushes the roof up. The ram is used to force wrecked sections of a vehicle apart in order to free trapped victims. The force of the fluid forces the piston to move the other piston up and down the cylinder. Pressurized phosphate – ester fluid is pumped into the cylinder by one of the two available attached hoses. This type of fluid is favored over the customary oil used in other hydraulic equipment because of its unique properties: it is fire – resistant and it does not conduct electricity.
The ram is a simple cylinder that has pistons and a special type of fluid inside it. These life – saving tools are powered by hydraulics, although, they can also be powered by electricity and pneumatics. To date, these tools have already saved thousands and thousands of human lives. Only trained emergency workers are authorized to use any of the “Jaws of Life” tools.
The “Jaws of Life” tools are also used to extricate victims trapped in debris resulting from natural disasters such as hurricanes, earthquakes, tornadoes, et cetera. These tools are used most commonly by emergency rescue teams to remove accident victims that are trapped in their vehicles. These tools include the ram, cutters, and spreaders. The “Jaws of Life” is actually a brand name of rescue tools that are trademarked by the Hurst Jaws of Life company. When you hear the familiar term, “Jaws of Life”, you probably think of a single life – saving device that is used by the rescue teams to free accident victims.
