The present invention relates to a trolley system having a safety ratchet arm for maintenance of rail mounted quay crane (RMQC) trolley rails. According to the present invention, the trolley system having a safety ratchet arm for maintenance of RMQC trolley rails has a main configuration comprising a maintenance trolley body (100), trolley wheels (200), safety ratchet arms (300), and jack modules (400). The trolley system is improved in structure so that the safety ratchet arm automatically turns by its own weight without power, and then returns and sits on the running rail, so that when installing and dismantling the maintenance trolley body, shaking or tilting is prevented to ensure the safety of work at height.

    본 발명은 안전 래칫암을 구비한 RMQC 트롤리 레일 정비용 트롤리시스템에 관련되며, 이는 안전 래칫암이 무동력으로 자중에 의해 자동으로 선회작동 후 복귀되어 주행레일 상에 안착되도록 구조 개선되어, 정비용 트롤리본체를 설치 및 해체시 흔들림이나 기울어짐이 방지되어 고소작업의 안전성을 확보할 수 있도록 정비용 트롤리본체(100), 트롤리휠(200), 안전 래칫암(300), 잭 모듈(400)을 포함하여 주요구성으로 한다.
