Method for inspecting operation of actuator and actuator operation inspector
摘要:
An actuator used in a safety stop device for an elevator has: a movable portion displaceable between an actuation position where the safety stop device for the elevator is actuated and a normal position where the actuation of the safety stop device is released; and an electromagnetic coil for displacing the movable portion when a current flows through the electromagnetic coil. A device for inspecting operation of the actuator has a feeder circuit for supplying an amount of electricity required for a semi-operation which is less than that required for a full operation for displacing the movable portion from the normal position and the actuation position to the electromagnetic coil.
