The present invention relates to a catenary trolley fall prevention device installed on both sides of a boom. The catenary trolley fall prevention device can be installed in a very narrow space formed on the boom side of a container crane by enabling a driving unit to be separately arranged from a main frame and improving the structure of the main frame in a very compact manner, can avoid interference when the catenary trolley is moved, and enables a buffer to be deployed to a catenary trolley fall prevention position by an arc motion of a main shaft. The present invention can stably prevent a catenary trolley from falling even when exposed to a strong external force such as a typhoon or an impact. A driving device is installed to be spaced at an angle of 90 degrees with respect to a direction of a force applied to a buffer and transmits power through an open gear. Therefore, a load is not transmitted to the driving device even when an impact force or a large external force is applied to the buffer. The catenary trolley fall prevention device comprises a main shaft (10), a driving module (20), and a buffer frame (30).

    본 발명은 Boom 양측면 설치형 캐트너리 트롤리 추락방지장치에 관련되며, 이는 구동부를 메인 프레임에서 분리 배치하는 것이 가능해져, 메인 프레임 부위가 매우 콤팩트하게 구조 개선되므로, 컨테이너크레인의 붐 측면에 형성되는 매우 협소한 공간에 설치 가능하고, 캐트너리 트롤리 이동시 간섭을 피할 수 있고, 메인샤프트의 원호운동에 의해 버퍼가 캐트너리 트롤리 추락방지 위치로 전개된다. 태풍이나 충격같은 강한 외력에 노출되더라도 캐트너리 트롤리를 안정적으로 추락방지 할 수 있고, 구동장치는 버퍼가 받는 힘의 방향과 90도 각도를 가지고 이격 설치되면서 open gear를 매개로 동력을 전달하므로, 버퍼에 충격력이나 큰 외력이 작용해도 구동장치에는 하중이 전달되지 않도록 구성되며, 메인샤프트(10), 구동모듈(20), 버퍼프레임(30)을 포함하여 주요 구성으로 한다.
