PROBLEM TO BE SOLVED: To provide a method for installing a control valve for a hydraulic elevator to which additional functions can be easily added.SOLUTION: An arbitrary part of a fluid feed pipe 4 provided between a power unit 3 and a hydraulic jack 2 is removed and then an additional control valve with pipes 10 that have the pipes on both ends is installed. The length (distance between the end of one pipe and the end of the other pipe) of the control valve with pipes 10 is same as the length of the removed part of the fluid feed pipe 4. An additional control unit 11 for controlling the control valve with pipes 10 is provided independently from the existing control unit 9. Only a cable required to control the control valve with pipes 10 and a cable, which is required for the purpose of control, between the additional control unit and the control unit 9 are connected to the additional control unit 11.

    【課題】付加機能の追加を容易に行なうことができる油圧式エレベーターの制御弁取り付け方法を提供する。【解決手段】パワーユニット3から油圧ジャッキ2の間に設けられている油送管4のうち、任意の箇所を取り外し、代わりに、追加制御弁の両端側に配管を有する配管付き制御弁10を取り付ける。この配管付き制御弁10の長さ(一方の配管の端部と他方の配管の端部との距離)は、取り外した油送管4の長さと同じである。また、配管付き制御弁10を制御するための追加制御部11を、既存の制御部9とは独立して設ける。追加制御部11は、配管付き制御弁10を制御するための配線と、制御部9との間で、制御上必要な配線のみ接続する。【選択図】図2
