To provide a renewal method of an elevator, which includes a control device in a hoistway, capable of operating a car even in a state where a work building for performing renewal work with respect to the control device is installed.SOLUTION: When starting renewal work for a control device, a temporary limit switch for sensing excessive movement of a car with respect to a prescribed floor above the lowermost floor is installed. A shock absorber is moved upward so as to absorb the shock generated when a car passes the prescribed floor. A work building for carrying out renewal work with respect to the control device is installed. The setting for operating a car is performed at a floor at or above the prescribed floor. When finishing the renewal work for the control device, the work building is removed and the setting for operating the car between the uppermost floor and the lowermost floor is performed.SELECTED DRAWING: Figure 4

    【課題】昇降路内に制御装置を含むエレベータにおいて、制御装置についてリニューアル作業するための作業用建築物が設置されている状態であってもかごを運転し得るエレベータのリニューアル方法を提供する。【解決手段】制御装置についてリニューアル作業を開始する際、最下階よりも上方の所定の階に対してかごの行き過ぎた移動を感知する仮設リミットスイッチを設置し、かごが所定の階を行き過ぎたときの衝撃をやわらげるように緩衝器を上方に移動し、制御装置についてリニューアル作業するための作業用建築物を設置し、所定の階以上の階においてかごを運転するための設定を行い、制御装置についてリニューアル作業を終了する際、作業用建築物を撤去し、最下階と最上階との間においてかごを運転するための設定を行うようにした。【選択図】図4
