To provide a wear inspection system of an elevator capable of monitoring the operation of a hoist and a car by installing a magnet sensor and a vibration sensor, and capable of detecting the wear state of a sheave and a brake.SOLUTION: A wear inspection system of a rope-type elevator comprises a magnetic detector to detect the motor operation of a hoist, an acceleration detector to detect pulley vibration and at least one of the elevating and lowering of the car, and a wear inspection device to determine the wear state of a sheave and a brake based on the output of the magnet detector and the acceleration detector. The wear inspection device is a wear inspection system characterized by determining that the sheave or the brake is worn when the braking time is longer than the predetermined threshold, where the braking time is defined by the time from when the power supply to a running motor is stopped until the car stops.SELECTED DRAWING: Figure 5

    【課題】 磁気センサと振動センサを設置することで巻上機と乗りかごの動作を監視し、シーブ及びブレーキの摩耗状態を検出することのできるエレベータの摩耗検査システムを提供する。【解決手段】 ロープ式エレベータの摩耗検査システムであって、巻上機のモータの動作を検出する磁気検出装置と、プーリの振動と乗りかごの昇降の少なくとも一方を検出する加速度検出装置と、前記磁気検出装置と前記加速度検出装置の出力に基づいて、シーブとブレーキの摩耗状態を判定する摩耗検査装置と、を備えており、前記摩耗検査装置は、稼働中の前記モータへの給電を停止してから、前記乗りかごが停止するまでの制動時間が、所定の閾値よりも長い場合、前記シーブまたは前記ブレーキが摩耗していると判定することを特徴とする摩耗検査システム。【選択図】 図5
