Abstract (en)
[origin: EP1939125A1] In an elevator apparatus, running of a car is braked by a first brake device and a second brake device. Operations of the first brake device and the second brake device are controlled by a brake control portion. When a sudden stop command to make a sudden stop of the car is issued, the brake control portion first causes the first brake device to perform braking operation. When the deceleration of the car is equal to or smaller than a predetermined value after a lapse of a predetermined time, the brake control portion causes the second brake device to perform braking operation.
