PURPOSE:To improve riding comfortableness by preventing a lift device, for lifting/lowering a cage through a wire rope by a hydraulic cylinder, from a rapid position change in the case of starting the device moved after a door is closed. CONSTITUTION:An actuating method in which a holding clamp, formed of a friction pad for fixing a rail, provided in a vertical direction for guiding rise/fall of the cage, and this cage, is first gradually and then quickly opened in the case of starting the rise/fall of the cage. Inn the case of a hydraulic circuit of the holding clamp formed of the friction pad for fixing the above- mentioned rail and cage, in a stop position of the cage in the above-mentioned lift device, and actuated by a clamping hydraulic cylinder (8), a throttle valve 24 is provided in a communication path between a pressure chamber 22 in the above-mentioned hydraulic cylinder and an oil tank 27, to which operating oil of this cylinder returns, in the case of opening the holding clamp. |
