PROBLEM TO BE SOLVED: To provide a safety device of a hydraulic elevator that is enforced on 1st April 2014 and applied to the Building Standard Law enforcement ordinance Article 129, 10 Term 4.SOLUTION: When a pump 6 is activated, the power source of an electromagnetic on-off valve 8 is in an on state, and the electromagnetic on-off valve 8 is in an opened state. Pressure oil in a pressure oil tank 5 is suctioned through a suction port 4 by the pump 6, and circulates toward a hydraulic cylinder 1 in a pressure oil route 2. Pressure oil supplied to the hydraulic cylinder 1 elongates the hydraulic cylinder 1, and thereby a lifting base lifts. When the lifting base lifts up to an uppermost position, the pump 6 is stopped. When the pump 6 is stopped, the power source of the electromagnetic on-off valve 8 is in an off state, and the electromagnetic on-off valve 8 is in a closed state.

    【課題】簡単な構成で、平成26年4月1日に施行された建築基準法施行令第129条の10第4項に適合する油圧式昇降機の安全装置を提供する。【解決手段】ポンプ6が起動すると、電磁開閉弁8の電源がオンとなり、電磁開閉弁8は開いた状態となる。ポンプ6によって、圧油槽5内の圧油が吸込口4を介して吸引され、圧油経路2を油圧シリンダ1に向かって流通する。油圧シリンダ1内に供給された圧油は、油圧シリンダ1を伸ばし、これにより、昇降台が上昇する。昇降台が最上位置まで上昇したら、ポンプ6を停止する。ポンプ6が停止したら、電磁開閉弁8の電源がオフとなり、電磁開閉弁8は閉じた状態となる。【選択図】図1
