ABSTRACT:
A cable hoisting system primarily used to raise and lower dump body tailgates has two cables attached to each eyelet of a tailgate at one end and attached to a frame mounted, spring loaded reel at the other end. Locking the reel and raising the dump box causes both cables to be pulled through a series of channels and cable guides until tailgate is pulled firmly into a closed position so that hinge pins can be easily inserted from the ground. Tailgate closing can be fully automated by the addition of a air actuated and dash controlled reel locking and unlocking device. Each cable series has a spring of sufficient strength to forgive either erroneous reel locking or excess tension.
