ABSTRACT:
Hoist mechanism for a truck vehicle of the type having a pivotally movable load support frame. Opposed piston hydraulic cylinders are carried by the load support frame. Each of the hydraulic cylinders has a piston rod to which is attached a rotatable sheave. Another sheave is rotatably attched to the load support frame. A cable has one end thereof attached to the load support frame. The cable has portions in engagement with the sheaves and has a free end adapted to be attached to a load. A load is thus drawn upon the load support frame as the hydraulic cylinders are operated.
