To provide a damping device and a damping system capable of effectively suppressing resonance of an elevator rope in an arbitrary direction in plane due to a long-period earthquake ground motion regardless of length of the rope.SOLUTION: A damping device for an elevator rope, in which an X-Y table device is installed on the top and bottom of an elevator car, comprises multiple stoppers to stop the motion of an X-direction moving body and a Y-direction moving body, and multiple motors to release or actuate these stoppers. A relative displacement measuring device to sense resonance of an elevator rope is installed at the multiple locations on the side walls of an elevator hoistway, and is configured such that a control device issues the command to release the stopper to the motor when it senses the resonance of the rope. A rope attachment part changes from a fixed state to a free state by this release command, and the rope gets out of the resonance state due to changes in a vibration mode and a natural frequency of the rope.SELECTED DRAWING: Figure 1

    【課題】 長周期地震動によるエレベータロープの平面内任意方向の共振を、ロープの長さに関係なく、効率よく抑制できるような制振装置及び制振システムを提供すること。【解決手段】 エレベータの乗りかごの上部及び下部にX-Yテーブル装置を設置し、そのX方向移動体とY方向移動体の動きを停止させるための複数個のストッパ、及びこれらのストッパを解除又は作動させるための複数個のモータを装備した。又、エレベータ昇降路側壁の複数箇所にエレベータロープの共振を感知するための相対変位測定装置を設置し、ロープの共振を感知した時は、制御装置によりモータにストッパ解除の指令を出すように構成した。この解除指令により、ロープ取付け部は固定の状態から自由の状態に変化し、ロープの振動モードと固有振動数が変化して、ロープは共振状態から脱することになる。【選択図】図1
