To compensate for load fluctuations during the turning operation of a circulation type multi-car elevator and suppresses car speed fluctuations in the turning section.SOLUTION: A circulation type multi-car elevator comprises: a speed controller that controls the rotation speed of a hoisting machine and outputs a torque command; a load measuring device that measures the load of an elevator car; a car position measuring device that measures the position of a pair of the elevator cars in the ascending and descending directions; either one or both of a speed detector that measures the rotation speed and an angle detector that measures the rotation angle of the hoisting machine; and a car position estimation unit that estimates the position of the pair of the elevator cars from the output of the car position measuring device and the speed detector or the angle detector during a turning motion in which the pair of the elevator cars moves from one hoistway to the other at the upper and lower ends of a circulation type hoistway. The output of the speed controller is compensated on the basis of the elevator car position obtained by the car position estimation unit and the measurement result of the load measurement value.SELECTED DRAWING: Figure 9

    【課題】循環式マルチカーエレベーターの転向動作時の負荷変動を補償し、転向部でのかごの速度変動を抑える。【解決手段】巻上機の回転速度を制御しトルク指令を出力する速度制御器と、乗りかごの荷重を測定する荷重測定器と、乗りかご対の昇降方向の位置を測定するかご位置測定器と、巻上機の回転速度又は回転角度を測定する速度検出器又は角度検出器のいずれか一方又は両方と、乗りかご対が循環式の昇降路上端及び下端において一方の昇降路から他方の昇降路に移る転向動作の際に、乗りかご対の位置をかご位置測定器と速度検出器又は角度検出器の出力から推測するかご位置推定部と、を備える。そして、かご位置推定部によって得たかご位置と、荷重測定値の測定結果から、速度制御器の出力を補償する。【選択図】図9
