Abstract

A compact, light duty hand operated hoist having a drive train containing successive groupings of engaged pinions and wheels is characterized in that the pinions have less than five gear teeth, that such gear teeth and the gear teeth of the wheels with which they engage are helical and lengths of the gear teeth of the pinions are sufficient to provide a contact ratio of one or more.
