ABSTRACT:
The present invention is a retractable cargo box extension assembly for a cargo box having an area therein for hauling material. The invention includes a plurality of lift arm assemblies connected to a cargo box and to a top frame for selectively raising the top frame upwardly to an extended position and lowering the top frame to a retracted position. An interior wall connected to the top frame and extending down to the cargo box is provided for increasing the area in the cargo box when the lift arm assemblies are in the extended position. A closed loop drive system is connected to each of the lift arm assemblies and to one or more actuator means for simultaneously operating each of the lift arm assemblies when raising or lowering the top frame.
