ABSTRACT:
A truss boom attachment for mounting on a fork assembly operatively mounted on a material handling truck. The fork assembly includes a rigid upright frame which receives a pair of load carrying forks. The truss boom attachment comprises a generally longitudinally elongated rigid truss frame which has an upright rigid rear end and a front end. Detachable hooks are defined on the rear end of the truss frame for detachably securing the truss boom on the rigid fork assembly of the material handling truck. A cable assembly, including a load carrying drop block, is operatively carried on the material handling truck and the cable is guidably carried on the truss boom with the drop block passing downwardly from the front end of the truss boom so the material or load being handled by the truck can be readily moved from one location to another.
