<p>An elevator device in which a car damper is installed at the inside bottom part of a hoistway. A brake device for a hoist for braking the movement of a car is installed on the hoist. When the speed of the car is abnormal, a safety device controls the operation of the brake device for the hoist so that the speed of the car can be reduced to the allowable impact speed of the damper or less before the car reaches the position of the damper. When the speed of the car exceeds an overspeed detection level, the safety device starts to operate the brake device for the hoist. The value of the overspeed detection level in a predetermined district starting at the position of the damper is set according to the position of the car so that the speed of the car can be reduced to the value of the allowable impact speed of the damper at the position of the damper by braking applied by the brake device for the hoist to the car.</p> |
