Abstract: A hand hoist comprises a brake support member (1) for supporting brake plates (24, 25) and firmly mounted on a driving shaft (20) detachably connected through gears to a load pulley (32). A brake biasing member (2) is threadedly engaged on the brake support member by means of a ball screw (43-45), and a retainer ring (3) is fixed to an outer surface of the brake biasing member. A friction transmission ring (5) having a frusto-conical friction outer surface (4) is non-rotatably fitted on the retainer ring, and a manually rotated member (6) for rotating the brake biasing member relative to the brake support member includes a frusto-conical inner surface (7) mating with the frictional outer surface of the transmission ring. Belleville springs (9) urge these frusto-conical surfaces against each other, and they are made of different metals, such as steel, bronze or brass.

Abstract: A resettable lockout means for an overload indicating winch lever is disclosed that automatically trips in response to overload applied to the lever forcing the lever members out of normal operating alignment and actuating an associated overload indicator. The winch operator desiring to remove the tell-tale overload indication and to restore the members of the operating lever into normal operating alignment is required to reset the lockout device through a deliberate procedure involving removal of a lockout device holder, followed by manual resetting of the lockout device within the winch lever.
