In a maintenance driving control apparatus of an elevator, switches and other components operated at the time of maintenance are separated from a control panel and combined in a driving operation panel. A maintenance operation panel having this driving operation panel and at least one of a brake release device for remote operation, a meter for indicating a voltage of a speed generator, and car position confirmation unit utilizing movement of a rope or some other member is provided in the vicinity of an elevator hall. The maintenance driving control apparatus enables maintenance operations without directly operating the control panel or a hoisting machine.

Elevator maintenance/operation apparatus

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.
