The present invention relates to a safety brake mounted on a wire drum of a lift for a freight vehicle. The lift comprises: a motor; a driving changing part; a wire drum connected with a power connecting shaft and having a safety brake; first and second sheaves and a main brake linked with the wire drum through a wire to be driven; and a cage connected with the wire linked with the first and second sheaves to be lifted. When the cage, on which a freight vehicle is loaded, moves up and down in a vertical underground passage of a construction site, in an emergency, or in a dangerous situation, a double brake including the main brake and the safety brake mounted on the wire drum is operated to quickly and forcedly stop lifting of the cage inside the vertical underground passage, thereby lifting the cage more safely in a plurality of guide chains mounted inside a vertical frame beam of the vertical underground passage.

    본 발명은 카리프트본체에 모터, 구동변환부, 동력연결축과 연결되어 구동되고 안전브레이크가 설치된 와이어드럼과, 이 와이어드럼과 와이어로 연계되어 구동되는 제1.2시브 및 메인브레이크와, 제1,2시브와 연계된 와이어와 연결되어 승강되는 케이지로 구성되어 화물차량을 안착한 케이지가 건설공사현장의 수직 지하통로에서 수직으로 승강시 비상상황 발생시 또는 안전을 위협하는 상황발생시 수직 지하통로내에서 케이지의 승강을 강제적으로 신속하게 정지하도록 메인브레이크 및 와이어드럼에 설치된 안전브레이크로 구성된 이중브레이크를 작동하여 수직 지하통로의 수직프레임빔내에 설치된 다수개의 가이드체인들내에서 케이지가 보다 안전하게 승강하도록한 화물차량 리프트의 메인드럼에 설치된 안전브레이크에 관한 것이다.
