PROBLEM TO BE SOLVED: To enable detection of a load inside an elevator car before activation of an elevator device without using a load detecting device, and to prevent an increase in the number of devices.SOLUTION: In an elevator device disclosed in the invention, for achieving a purpose described above, a control board which detects a position and a speed of an elevator car from a detection signal of an encoder for detecting rotations of a governor where a governor rope is wound includes: a load inside an elevator car estimation section for estimating a load inside the elevator car from travel torque of the elevator device; and a load inside an elevator car fluctuation estimation section during a halt of an elevator device for acquiring a fluctuation amount of the load inside the elevator car during the halt of the elevator device. The load inside the elevator car during the halt of the elevator device is estimated by adding an estimation value of the load inside the elevator car that is estimated by the load inside an elevator car estimation section from the travel torque of the elevator device and the fluctuation amount of the load inside the elevator car during the halt of the elevator device that is acquired by the load inside an elevator car fluctuation estimation section during a halt of an elevator device.

    【課題】荷重検出器を用いることなく、エレベータ装置起動前の乗りかご内の荷重を検出でき、装置数が増大しないこと。【解決手段】本発明のエレベータ装置は、上記目的を達成するために、ガバナロープが巻き掛けられたガバナの回転を検出するエンコーダの検出信号から乗りかごの位置及び速度を検出する制御基板が、エレベータ装置の走行トルクから乗りかご内の荷重を推定する乗りかご内荷重推定部と、エレベータ装置停止中の乗りかご内の荷重変動量を求めるエレベータ装置停止中の乗りかご内荷重変動推定部とを備え、乗りかご内荷重推定部で推定されたエレベータ装置の走行トルクからの乗りかご内荷重推定値と、エレベータ装置停止中の乗りかご内荷重変動推定部で求められたエレベータ装置停止中の乗りかご内の荷重変動量とを足し合わせることで、エレベータ装置停止中の乗りかご内荷重を推定することを特徴とする。【選択図】図1
