ABSTRACT:
When a hoist is used to elevate a grain truck for dumping same, at an elevator terminal or the like, a pair of lift cables extend from the overhead hoist assembly to the cradle upon which the front wheels of the truck are engaged. As the truck is lowered after emptying the grain therefrom, the slack cables often foul the truck as it is being driven from the cradle. In the present device, each cable passes through a spring loaded arm normally urging the cables outwardly away from the sides of the truck thereby clearing same, but which are aligned against the spring pressure as soon as the lifting load is applied so that the cables run vertically from the hoist assembly.
