ABSTRACT:
In a brake apparatus for a hoisting machine of an elevator, a field magnet and an armature of an electromagnetic actuator are mounted directly to brake arms supporting brake shoes. Therefore, members for transmitting the motion of an electromagnetic actuator into the motion of the brake arms can be omitted, whereby the number of parts and the overall size of the hoisting machine can be reduced, and maintenance operations can be performed easily at lower positions.
