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 selectable 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. The arms or jaws are removable for interchanging between cutting and spreading configurations, or replacement with general purpose arms capable of both cutting and spreading operations.
