Abstract
A light weight, quiet and emergency safe, portable 'jaws of life' spreading tool actuated by an electric motor. Full high torque at any position, with spreading or cutting motions under high loads is achieved by the use of a rotary, multiple stage, speed reducing gearbox driven by the motor. The gearbox contains an input stage from the electric motor running on a 12 volt DC power supply, and a compound planetary output stage. The arms or jaws of the device are separately driven by the planetary or spindle gears and, for convenience, are attached to external rings on the gears, by heavy duty pins.
