The present invention relates to a fall prevention lift which automatically recognizes abnormal lowering operation if the abnormal lowering operation occurs on one of the left and right sides of the lift after a vehicle is lifted, to prevent the lowering operation and compensate for the lowering operation by being raised by a lowering distance by hydraulic pressure control or a mechanical driving operation. More specifically, the fall prevention lift comprises: first and second plates; a pair of posts along which the first and second plates are guided; first and second actuators for raising and lowering the first and second plates; and a hydraulic pressure supply unit for supplying and recovering hydraulic pressure to and from the first and second actuators. Therefore, the fall prevention lift can adjust hydraulic pressure to maintain the balance of the vehicle when the vehicle is raised and lowered, to immediately cut off the loss of hydraulic pressure even when the loss of hydraulic pressure occurs with the vehicle raised, thereby preventing a fall or damage to the vehicle and an accident.

    본 발명은 차량을 리프트 후 좌·우측 중 하나에 비정상적인 하강작동이 발생할 경우 자동으로 인지하여 하강작동을 방지하는 동시에 유압력 조절이나 기계적 구동작동으로 하강거리만큼 상승보상하는 추락방지 리프트 장치에 관한 것으로, 더욱 상세하게는 제1,2플레이트, 상기 제1,2플레이트가 안내되는 한 쌍의 지주, 상기 제1,2플레이트를 승강 및 하강시키는 제1,2액츄에이터, 상기 제1,2액츄에이터에 유압을 공급 및 회수하는 유압공급부로 구성하여, 차량을 승강 및 하강시 정확한 균형을 유지하도록 각각 유압량을 조절할 수 있어 차량을 상승시킨 상태에서 유압력의 소실 현상이 발생하더라도 유압의 소실을 즉시 비상 차단가능하여 차량의 추락이나 파손, 안전사고를 미연에 방지하는 효과가 있다.
