ABSTRACT:
A hoist is constructed for powered drive by an impact tool. The hoist includes tension means for applying a force in tension to a load. Gear means are operatively associated with the tension means for producing a tension force in the tension means. The gear means include a gear element which provides a positive hold of the produced tension force when the gear means are not being driven. Impact fitting means are connected to the gear element for enabling the gear means to be power driven by an impact tool.
