Zusammenfassung:PROBLEM TO BE SOLVED: To provide a mechanism for compensating eccentric load of an elevator car, capable of suppressing noise and vibration transmitted to the car without weight increase of a car frame.SOLUTION: A compensation rope 6 is divided to N sets (N is an integral of 2 or more) and one ends of respective sets of compensation ropes 6a-6d are attached to positions on a bottom surface of a car 1 of an elevator, the positions are separated from each other. A load measurement device 12 measures load which guide devices 8a-8d receive from a guide rail, and a tension adjustment device 16 applies tension for every set of the compensation ropes. A control device 17 controls the tension adjustment device 16 on the basis of a measured value of the load measurement device 12. 【課題】エレベータのかごの偏心荷重を補償する機構において、かご枠の重量増加がなく、かごへ伝達される振動や騒音を抑制すること。【解決手段】エレベータは、補償ロープ6がN組(Nは2以上の整数)に分割されて、各組の補償ロープ6a〜6dの一端がかご1の底面の互いに離れた位置に取り付けられる。荷重計測装置12は、ガイド装置8a〜8dがガイドレールから受ける荷重を計測し、張力調整装置16は各組の補償ロープ毎に張力を付与する。制御装置17は荷重計測装置12の計測値に基づいて張力調整装置16を制御する。【選択図】図1
