PROBLEM TO BE SOLVED: To provide a main rope unbalance compensator of an elevator capable of suppressing an ascent of a tension wheel without biting into a rail when the tension wheel jumps up following a sudden stop of the elevator while detecting an ascent of the tension wheel and stops an operation of a hoist before a jumping-up prevention part suppresses an ascent of the tension wheel.SOLUTION: A main rope unbalance compensator 30 includes a compensation rope 36b, one end of which is connected to the bottom edge of a car 14, and the other end of which is connected to a lower side of a counter weight 16, a tension wheel 36 for importing tension to the compensation rope 36b, a jumping-up prevention part 40 provided above the tension wheel 36 that includes an elastic stopper 44 on the lower surface side, a safety switch 50 provided at a predetermined position on the lower end side of the elastic stopper 44 that detects the tension wheel 36, and a control part 20 for controlling an operation of the hoist 12. The control part 20 stops an operation of the hoist 12 when the safety switch 50 detects the tension wheel 36.SELECTED DRAWING: Figure 1

    【課題】跳ね上がり防止部が張車の上昇を抑制する前に張車の上昇を検知して巻き上げ機の運転を停止させつつ、エレベータの急停止に伴って張車が跳ね上がったときにはレールに食い込むことなく張車の上昇を抑制することができるエレベータの主ロープアンバランス補償装置を提供する。【解決手段】主ロープアンバランス補償装置30は、一端が乗りかご14の下端に接続され、他端がカウンタ錘16の下側に接続される補償ロープ36bと、補償ロープ36bに張力を付与する張車36と、張車36の上方に設けられ下面側に弾性ストッパ44を有する跳ね上がり防止部40と、弾性ストッパ44の下端側の所定位置に設けられ、張車36を検出する安全スイッチ50と、巻上機12の運転を制御する制御部20とを備え、制御部20は安全スイッチ50が張車36を検出したときに巻上機12の運転を停止させる。【選択図】図1
