PROBLEM TO BE SOLVED: To eliminate the need of early replacement of a lining, and to reduce damages to a rope caused by confirming operation.SOLUTION: A rope brake device of an elevator comprises: brake parts arranged in a pair and arranged at a position where a rope wound around a sheave and a pulley in a hoist, suspending a car at one end side thereof, and suspending a balancing weight at the other end side thereof, can be caught and held; and a drive part that is de-energized or energized during braking time, and which is caught and held sandwiching a portion of the rope by the brake parts. The rope brake device also comprises a controller that gradually attenuates or amplifies a voltage supplied to the drive part and controls the rope to be caught and held slowly by the drive parts when confirming operation of the rope brake device.SELECTED DRAWING: Figure 2

    【課題】ライニングを早期に交換する必要がないことは勿論、動作確認に伴うロープへのダメージを軽減することができること。【解決手段】本発明のエレベーターのロープブレーキ装置は、上記課題を解決するために、巻上機のシーブとプーリーに巻き掛けられて、一端部側に乗りかごが吊持されると共に、他端部側につり合いおもりが吊持されたロープを拘束保持できる位置に配置され、対となって配置されるブレーキ部と、制動時に消勢又は付勢され、前記ブレーキ部で前記ロープの一部を挟んで拘束保持させる駆動部とを備えたエレベーターのロープブレーキ装置において、前記ロープブレーキ装置の動作確認時に、前記駆動部へ供給する電圧を徐々に減衰又は増幅させ、前記ブレーキ部による前記ロープの拘束保持を緩徐に制御する制御装置を備えていることを特徴とする。【選択図】図2
