Abstract
Abstract An input shaft is provided with circumferentially spaced ramps which confront opposed ramps on a coaxially aligned ramp shaft. The ramp shaft is provided with a sun gear which can rotate only through a one-way clutch and brake discs. The sun gear drives a drum through a planetary drive system. The ramps each are provided with a shoulder, balls being trapped between the ramps. Rotation of the input shaft in a hoisting direction drives the ramp shaft by passing the brake through the one-way clutch.
