ABSTRACT:
Apparatus for changing bodies on a vehicle includes a long beam platform pivotally connected at its rearward end to that of the vehicle chassis, a hoist to pivot the platform and a pair of hydraulic cylinder winches having a set of multiwrap sheaves at either end and mounted to both sides of the platform. The sheaves are multiwrapped with a cable secured at one end and securable to the truck body at the other end. The cylinders extend in the direction of loading to maximize travel efficiency and eliminate the need for an idler sheave. Retractable locking means are provided on the platform for locking the body into place. By operation of the hoist and winches, the vehicle body may be quickly and safely mounted onto or demounted from the platform whether loaded or unloaded.
