PROBLEM TO BE SOLVED: To provide a brake diagnosis method for an elevator capable of performing feedback to clarify mechanism and causes of deterioration to suppress occurrence of failure and to improve a product.SOLUTION: A brake diagnosis method for an elevator for diagnosing a deterioration of a brake braking a motor driving a car 1 and a balancing weight 2, comprises: collecting brake releasing (braking) time data as brake deterioration information; collecting, every time the elevator starts, loads within the car 1 at a start floor and a stop floor, and loads within the car 1 at traveling time and starting time as elevator operation data; and diagnosing the brake deterioration according to the brake deterioration information data and the elevator operation information.SELECTED DRAWING: Figure 2

    【課題】劣化メカニズムや劣化原因の明確化による故障抑止、及び製品改善へのフィードバックを図ることができるエレベータのブレーキ診断方法の提供。【解決手段】本発明は、乗かご1および釣合い重り2を駆動するモータを制動するブレーキの劣化状態を診断するエレベータのブレーキ診断方法であって、ブレーキの釈放(制動)時間をブレーキ劣化情報として収集し、エレベータの起動毎に、起動階及び停止階における乗かご1内の負荷、また走行時及び起動時における乗かご1内の負荷をエレベータ稼働情報として収集し、ブレーキ劣化情報とエレベータ稼働情報とに基づいて、ブレーキの劣化状態を診断するものである。【選択図】図2
