Abstract (en)
A shock absorber for a car is provided at a bottom within a hoistway. A hoisting machine is provided with a hoisting machine brake device for braking a movement of the car. A safety device controls an operation of the hoisting machine brake device when there is an abnormality in a speed of the car such that the speed of the car becomes equal to or lower than an allowable collision speed of a shock absorber before the car reaches a position of the shock absorber. The safety device starts the operation of the hoisting machine brake device when the speed of the car exceeds an overspeed detection level. A value of the overspeed detection level in a predetermined interval from the position of the shock absorber is set in accordance with a position of the car such that the speed of the car becomes equal to the allowable collision speed of the shock absorber at the position of the shock absorber through braking of the car by the hoisting machine brake device.
