ABSTRACT:
A wrecker assembly is combined with a pick up truck or cab and chassis having a frame, a rear axle, a cab and/or a floor, side walls, and a battery. The wrecker assembly comprises a sub-frame assembly mounted upon the floor or frame and is secured to the frame. The boom including a pair of forwardly diverging side plate ends is pivotally mounted upon the sub-frame adjacent the cab. A tower mounting plate spans the boom side plates and projects thereabove. A hydraulic power cylinder including a reciprocal piston rod is pivotally mounted upon the sub-frame assembly with the end of the piston rod pivotally connected to the tower plate at its upper end. A power pack including a motor, pump, valve and a fluid reservoir is mounted upon the boom and a pair of flexible conduits respectively interconnect the pump valve and opposite ends of the cylinder. An electrical circuit includes a manual "forward and reverse" switch interconnecting the battery with the motor and valve for selective raising and lowering of the boom.
