发明名称 CABLE RIGGING ARRANGEMENT FOR HOIST
摘要 An improved system for single or double rigging a load sustaining device, such as a cable hoist, to permit selective alteration of the load capacity thereof. A load sustaining element, such as a wire cable, is operatively connected with the operating mechanism of the hoist and passes through a hook and pulley structure to be engaged with a load. The cable end is provided with a collar structure which precludes separation of the cable from the hook and pulley structure when single cable rigging is desired. The hoist housing is provided with slotted recess structure which permits easy insertion of the collar structure into the housing when double cable rigging is desired.
