Abstract
PURPOSE: To shorten the rescue time of an elevator cage in emergency by automatically elevating tha cage by releasing an electromagnetic brake via an emergency power supply at malfunctioning time to elevate the cage to the nearest floor upon driving of the cage via an auxiliary motor when the cage does not reach the floor even after predetermined time is elapsed.
CONSTITUTION: Assuming that an elevator cage has small unbalanced load, an electric power is interrupted during downward elevation of the cage, and the cage idly elevates with small unbalanced load, a time limit relay 13 is operated to close its contact 13a when time T1 is elapsed after the interruption of the power. Accordingly, an inertial elevation stop relay 17 is energized to close its contact 17b to self- hold so as to thus brake the cage to stop it. When predetermined time T2 is elapsed, a time limit relay 16 is reset to release the brake. When an auxiliary motor 6 is driven upon closing of the contact 16a to start the cage to cause the cage to arrive at the nearest door openable zone, the brake is operated to stop the cage so as to thus rescue passengers in the cage on the nearest floor.
