PROBLEM TO BE SOLVED: To provide a balance device detecting a load at an end part of a main rope of a general elevator and having a detection plate and a detector without requiring adjustment of an initial position where the detection plate is displaced in a detection range of a displacement detector.SOLUTION: An elevator includes a hoisting machine, a car, a counterweight, a plurality of main ropes wound around the hoisting machine and suspending the car and the counterweight, and a balance device in end parts of the main ropes at the car side. The balance device includes a main rope receiving part for supporting the end parts of the main ropes and a main rope receiving support part for supporting the main rope receiving part and changing a deflection amount according to the load applied to the end parts of the main ropes. The balance device includes an arm 19 whose inclination is changed by the displacement of the main rope receiving part and an angle detector 20 for detecting an angle of the arm 19.SELECTED DRAWING: Figure 2
【課題】一般のエレベーターの主索の端部にて荷重検出を行う秤装置は、検出板と検出器を持つ。検出板が変位検出器の検出範囲内で変位するような初期位置の調整が不要になる装置を提供する。【解決手段】巻上機、乗りかご、釣り合い重り、巻上機に巻きかけられ乗りかご及び釣り合い重りを懸垂する複数の主索、主索のかご側の端部に秤装置を備え、秤装置は主索の端部を支持する主索受け部、主索受け部を支持し主索の端部にかかる荷重によってたわみ量を変化させる主索受け支持部を備えるエレベーターに於いて、秤装置は主索受け部の変位によりその傾きが変化するアーム19、アーム19の角度を検出する角度検出器20を有することを特徴とする。【選択図】図2
