PROBLEM TO BE SOLVED: To provide a method for modifying a direct connection type hydraulic elevator in which the direct connection type hydraulic elevator can be modified into a non-hydraulic elevator without decreasing the size of an elevator car.SOLUTION: The present invention relates to a method for modifying a direct connection type hydraulic elevator in which the direct connection type hydraulic elevator is modified into a non-hydraulic elevator, the method comprising: a cylinder detaching process of detaching a cylinder from an underground pipe 1 provided below a hoistway 100; a screw rod fitting process of coupling an upper end part of a screw rod 2 to an elevator car 3 after the cylinder detaching process and inserting a lower end part of the screw rod 2 into the underground pipe 1; and a drive device installing process of installing a drive device 4 for moving up and down the screw rod 2 in the underground pipe 1 in the hoistway 100.SELECTED DRAWING: Figure 1

    【課題】かごのサイズを小さくすることなく直結式油圧エレベータを非油圧エレベータに改修することができる直結式油圧エレベータの改修方法。【解決手段】直結式油圧エレベータを非油圧エレベータに改修する直結式油圧エレベータの改修方法であって、昇降路100よりも下方に設けられた地中管1からシリンダを取り外すシリンダ取外工程と、シリンダ取外工程の後、ねじ棒2の上端部をかご3に連結し、ねじ棒2の下端部を地中管1に挿入するねじ棒取付工程と、ねじ棒2を地中管1に対して上下方向に移動させる駆動装置4を昇降路100に設置する駆動装置設置工程とを備えている。【選択図】図1
