Title: Dump-hoist conversion system

Abstract: A dump-hoist conversion system particularly suited for providing a dump capability in pick-up trucks. A modified scissors hoist is utilized having transversely spaced lower channel members as well as lift members. These components mutually nest when the bed of the truck is down and are located on either side of the differential gear housing in such down position. A dump pivot hinge is provided having a hinge axis lower than the upper surface of the side rails of the undercarriage frame. This provides a safety aspect against rear-end collisions. Hydraulic drive is provided through the utilization of a 12 volt d.c. motor which operates from the battery circuit of the vehicle.
