Title: ELEVATOR APPARATUS
Abstract:
This elevator apparatus is provided with a cage, a brake device that applies a brake on the driving of the cage, and a door-open driving protection device. A tolerance zone, which is a zone in which movement of the cage with the door being open is tolerated, is set for the door-open driving protection device. The door-open driving protection device stops the cage by means of the brake device when the cage with the door being open deviates out of the tolerance zone. In addition, the door-open driving protection device is capable of changing the range of the tolerance zone in accordance with the braking ability of the brake device.
