摘要

Movement of an elevator cab drive sheave is controlled by a disc brake assembly which is operably connected to the output shaft and sheave of the elevator drive machine The disc brake assembly can act as an upward or downward safety brake, and can also serve as the operating brake for normal operation of the elevator. The brake assembly can be retrofitted onto an existing elevator system, and its operation is not affected by any gear degradation in the machine drive gears.
