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 a plurality of brake discs. The sun gear drives a drum through a planetary drive system. The ramps each are provided with a shoulder. Balls are trapped between the ramps. Rotation of the input shaft in a hoisting direction drives the ramp shaft bypassing the brake through the one-way clutch. Thus the drum is rotated by the torque through the balls and shoulders. The brake discs are set by springs so that the load remains braked when hoisting is stopped. In the power down condition the input shaft rotates relative to the ramp shaft so that the balls move along the ramps spreading the shafts and compressing the springs so that the brake discs are released.
