Abstract

An elevator has a first setting speed that is set according to a position of an elevator car (70) and a second setting speed that is set higher than the first setting speed wherein a first brake device (11) is actuated when a speed of the car (70) becomes higher than the first setting speed and a second brake device (13) is actuated when the speed of the car (70) becomes higher than the second setting speed. The elevator further has a third setting speed that is set higher than the second setting speed; and a vibration detector (8) that detects a change in the speed of the car (70) when the speed of the car (70) exceeds the first setting speed and the first brake device (11) is actuated wherein the second brake device (13) is actuated based on the change in the speed of the car (70) and on the second setting speed or the third setting speed.
