To provide a renovating method of a hydraulic elevator to a non-hydraulic elevator capable of reducing waste disposal and also of reducing man-hour of a renovating construction and of shortening a construction period.SOLUTION: A renovating method of a hydraulic elevator to a non-hydraulic elevator has steps of: extracting hydraulic oil to drive a hydraulic jack from an oil tank of a hydraulic power unit installed in an engine room; extracting hydraulic oil from the hydraulic jack; extracting hydraulic oil from a hydraulic oil pipeline one end of which is connected to the oil tank and the other end of which is connected to the hydraulic jack; forming the first opening in the hydraulic oil pipeline arranged between the oil tank and the inner wall of the engine room; forming the second opening in the hydraulic pipeline arranged between the hydraulic jack and the inner wall of a hoistway; and passing a power cable of the non-hydraulic elevator in the hydraulic pipeline via the first and the second openings.SELECTED DRAWING: Figure 3

    【課題】改修工事の工数を減らして工期を短縮するとともに廃棄物の量を削減することのできる、油圧式エレベーターの非油圧式エレベーターへの改修方法を提供する。【解決手段】機械室に設置された油圧パワーユニットのオイルタンクから、油圧ジャッキを駆動する作動油を抜き取る工程と、油圧ジャッキから作動油を抜き取る工程と、オイルタンクに一端側が接続され、他端側が油圧ジャッキに接続される作動油配管から作動油を抜き取る工程と、オイルタンクと機械室の内壁との間に配置された作動油配管に、第1の開口部を形成する工程と、油圧ジャッキと昇降路の内壁との間に配置された作動油配管に、第2の開口部を形成する工程と、第1の開口部及び第2の開口部を介して、作動油配管の中に非油圧式エレベーターの電源ケーブルを通す工程とを有する。【選択図】図3
