An objective of the present invention is to provide an electrically-driven rail lift which can be easily used even by a weak worker. According to the present invention, the electrically-driven rail lift comprises: a main body having a rail wheel installed on a lower portion thereof to be moved on a rail, and a lifting support post erected upward and installed on both sides thereof; a lifting rod bar installed on the main body to be vertically lifted while the upper end thereof protrudes, elastically supported upward by an elastic member, and provided with a moving wheel installed on the lower end thereof; a lifting plate installed on an upper portion of the main body to be vertically lifted along the lifting support post, and formed to allow a worker to ride on an upper portion thereof; and a lifting driving unit which is installed to lift or lower the lifting plate, positions the moving wheel lower than the rail wheel with respect the ground while the lifting plate presses the upper end of the lifting rod bar to lower the lifting rod bar when lowering the lifting plate, and positions the moving wheel higher than the rail wheel while the pressing operation on the lifting rod bar is stopped and the lifting rod bar moves upward by the elastic member when lifting the lifting plate.
본 발명의 전동레일리프트는, 레일 상에서 이동 가능하도록 레일바퀴가 하부에 설치되고, 승강지주대가 양측에 상부로 직립 설치되는 본체와, 본체에 상단부가 돌출된 상태에서 상하로 승강 가능하게 설치되고, 탄성부재에 의해 상향으로 탄성 지지되며, 하단부에 이동바퀴가 설치되는 승강로드바와, 승강지주대를 따라 상하로 승강 가능하도록 본체의 상부에 설치되고, 작업자가 상부에 탑승할 수 있도록 형성되는 승강판과, 본체에 설치되어 승강판을 상승 또는 하강시키되, 승강판을 하강시키면 승강판이 승강로드바의 상단부를 눌러 하강시키면서 지면에 대하여 이동바퀴가 레일바퀴 보다 하부에 위치하도록 하고, 승강판을 상승시키면 승강로드바에 대한 누름동작이 해제됨과 아울러 탄성부재에 의해 승강로드바가 상부로 이동하면서 이동바퀴가 상기 레일바퀴 보다 상부에 위치하도록 하는 승강구동부를 포함할 수 있다.
