Abstract
A pneumatic brake assembly for incorporation into chain hoists and the like includes a planar disk slidably secured to the output shaft of a pneutmatic motor by complementary splines. The disk is biased toward a planar surface and when in contact with such surface, inhibits rotation of the motor output shaft. Compressed air is supplied to both the pneumatic motor and the brake assembly through a network of passageways and check valves. Compressed air supplied to one face of the brake disk, translates the disk, disengaging it from the planar surface and permitting output shaft rotation.
