To accurately assess the deterioration status of anti-vibration rubber in an elevator car so that the ride quality can be kept constant.SOLUTION: An elevator system comprises: a loading error amount estimation unit 15 that estimates a loading error amount of an elevator car based on the load amount of the elevator car and the vibration amount detected by a vibration detection sensor of the elevator car when the hoisting machine is started; a resonance frequency derivation unit 14 that derives the resonance frequency of the elevator car; and a spring constant estimation unit 16 that calculates a spring constant of an anti-vibration rubber installed in the elevator car based on the vibration amount detected by the vibration detection sensor, the loading error amount estimated by the loading error amount estimation unit 15, and the resonance frequency derived by the resonance frequency derivation unit 14 to estimate the deterioration status of the anti-vibration rubber.SELECTED DRAWING: Figure 2

    【課題】エレベーターの乗りかごの防振ゴムの劣化状況を正確に把握して、乗り心地を一定に保てるようにする。【解決手段】乗りかごの荷重量と、巻上機を起動した際の乗りかごの振動検出センサが検出した振動量から乗りかごの荷重量の誤差量を推定する積載誤差量推定部15と、乗りかごの共振周波数を導出する共振周波数導出部14と、振動検出センサが検出した振動量と、積載誤差量推定部15が推定した荷重量の誤差量と、共振周波数導出部14が導出した共振周波数に基づいて、乗りかごに設置された防振ゴムのばね定数を算出して、防振ゴムの劣化状況を推定するばね定数推定部16とを備える。【選択図】図2
