Abstract:
A drive system for a movable crossover box on the body of a pickup truck having a forward wall, with rearwardly extending side walls to form a truck box with upper forward corners and rearward corners, comprising:a pulley system comprising a single first and second pulleys at each rearward corner mounted for rotation about a horizontal axis, a first and second pair of upper and lower pulleys at each forward corner for rotation about a vertical axis, a continuous cable threaded from the first pulley at one rearward corner to the upper pulley at one forward corner, and thence to the upper pulley at the other forward corner, and thence to and around the second pulley at other rearward corner, and thence to the lower pulley at the other forward corner, and thence to the lower pulley at the one forward corner, and thence back to and around the first pulley at one rearward corner, to form upper and lower strands of cable substantially parallel to each other throughout the pulley system, a crossover box extending laterally across upper portions of the side walls for longitudinal movement thereon, the crossover box being secured by its ends to the cable to one of the upper or lower strands of cable, and power means on the truck for selectively moving the cable in one of two directions to longitudinally move the crossover box in forward or rearward directions on the side walls of the truck box.
