Using the spreader tool:
The spreaders are used to spread out the structures of an accident vehicle. The spreaders are also hydraulically powered and provide abundant power to quickly and easily rip off or pullout sections of the car. The cutters and spreaders are provided with power units that supply a powerful hydraulic pressure that is at the heart of Jaws of Life system. Currently, combination tools are also available that combine the functions of cutters and spreaders.
The spreader tool is pincer type equipment and is available in several sizes. The edges of the spreaders arms are made of special steel to resist heat and also to provide maximum strength for tearing apart a vehicle. The body of the spreader is connected to a portable engine that pumps oil through hoses into the body of the spreader. A valve switch is used for making the oil flow and is used to close or open the spreader arms. These tools are powerful and typically provide upwards of 12,000 pounds of spreading or pulling force and can create opening distance over 30 inches. The exact power and opening distance depend on the model of the tool being used.
To use the spreader, it is inserted with closed spreader arms into an opening in the automobile and then the spreaders are made to expand out. Alternatively, the spreader can also be used to crush any materials between its arms.
Using the rams:
The rams are hydraulic equipment used to push apart sections of the car or other crushed structures. In a ram, the piston rods visible on the outside are pushed in or out by piston heads inside the body cylinder. There is fluid on either side of the piston head that is fed by different hoses. If there is more pressure on one side off the piston head it moves the piston rods in one direction and vice versa. The rams are put to work at emergency situations to push apart sections of the accident vehicle for example to push outwards a dashboard that has collapsed inwards after an accident.
