The present invention relates to a lift fall preventing apparatus. Specifically, the present invention relates to a technology relates to the lift fall preventing apparatus. According to the present technology, when a main wire is cut and an elevation frame falls, the elevation frame is braked by a braking member connected to an auxiliary wire, thereby preventing the elevation frame from completely falling and causing an accident. The lift fall preventing apparatus of the present invention comprises: a fixation frame formed inside an elevation module; a pair of auxiliary wires installed at both ends of the fixation frame; a pair of braking members; and a plurality of catching grooves formed on the inner surface of a guide rail. The pair of braking members include: a fixation bracket coupled to the elevation frame; a spring installed at one end part of the fixation bracket; a pair of fixation pins formed on outer and inner sides of one end part of the spring, respectively; and a clamp formed in close contact with one side of the spring and rotationally coupled to the fixation pin formed outside the spring and having a stopper formed on the outer surface of the spring.

    본 발명은 리프트 추락방지 장치에 관한 것으로서, 상세하게는 메인와이어가 절단되어 승강프레임의 추락이 발생할 때 보조와이어와 연결된 제동부재에 의해 승강프레임을 제동시킴으로써 승강프레임이 완전히 추락하여 사고가 발생하는 것을 방지할 수 있는 리프트 추락 방지 장치에 관한 기술이다. 이러한 본 발명은 승강모듈의 내측에 형성되는 고정프레임; 상기 고정프레임의 양단에 설치되는 한 쌍의 보조와이어; 상기 승강프레임에 결합되는 고정브라켓과 상기 고정브라켓의 일단부에 설치되는 스프링과 상기 스프링의 일단부의 외측과 내측에 각각 형성되는 한 쌍의 고정핀과 상기 스프링의 일측에 밀착되어 형성되고 상기 스프링에 외측에 형성되는 고정핀에 회전 가능하게 결합되고 외면에 스토퍼가 형성되는 클램프를 포함하는 한 쌍의 제동부재; 상기 가이드레일의 내면에 형성되는 복수의 걸림홈;을 포함한다.
