ABSTRACT:
A boom assembly attaches to the fifth wheel of a tractor for towing a truck or other vehicle. The assembly has a pair of uprights and a pair of pivotally mounted legs. Hydraulic cylinders are actuated to force the legs to a pivoted position which lifts the legs and the towed truck to an elevated position for towing. The legs may be supported by a collapsable wheel assembly. The vehicle is secured by a specially configured hook and a variably positionable front wheel assembly receiver. Extensions in the legs include rollers to facilitate positioning. The boom assembly may be variably vertically positioned and is collapsable to a compact storage configuration.
