摘要： An elevator includes a compensating sheave, a compensating rope, a guide, a holder, a driver, a lateral vibration detector, and driver controller. The compensating rope is looped around the compensating sheave to be bent back upward in a hoistway, and has a first end connected to a car and a second end connected a counterweight, the compensating rope suspended from the car and the counterweight. The guide guides the compensating sheave in a vertically displaceable manner. The holder holds the guide to be displaceable in a horizontal direction. The driver drives the holder in the horizontal direction. The lateral vibration detector detects lateral vibration of the compensating rope. The driver controller controls the driver based on a result of detection by the lateral vibration detector and accordingly drive the holder in the horizontal direction so as to dampen lateral vibration of the compensating rope.

摘要： A damping device for a main rope suspending a car of an elevator includes a coupled, a first pulley and a drive. The coupler is attached to the main rope above the car, and is configured to be pulled, in response to vibrations of the main rope, with a damping rope so as to suppress vibrations of the main rope. The first pulley is supported at a same height as a height of the coupler. The drive is configured to suppress vibration of the main rope by pulling a first damping rope coupled to the coupler and passing over the first pulley.
