ABSTRACT:
A chainless drive winch is provided having a cable cylinder meshing with an orthogonal, cylindrical reduction gearing member. The reduction gearing member may be driven by, for example, an electric motor. A brake is provided operable only when the reduction gearing member is rotated is a direction to lower a load. Limit switches may be provided which are adjustable to alter the distance between them. A trigger finger moving between the limit switches is driven from the cable cylinder. The cable cylinder may be provided with a generally parallel roller to hold turns of cable on the cylinder. The roller may be independently biased at each end so that, when cable is partially unwound from the cylinder, the bias of the roller is enhanced on the remaining turns.
