摘　　要：本文通过阐述电动葫芦桥式起重机冲顶事故,详细分析桥式起重机械冲顶的原因,以及防控措施和改进方法。当起重机械冲顶事故的诱因存在时,设法阻断起升高度限位器失效或者上升接触器熔合、吸死。这个中间关联因素或者过渡环节,是防止起重机械冲顶事故的有效手段。This paper describes the Electric Hoist Bridge Crane Jacking accident,detailed analysis of bridge crane jacking causes,as well as prevention and control measures and improvement methods.When the cause of the jacking accident of the crane is present,try to block the intermediate related factor or transitional link of the failure of the lifting height limiter or the fusion and suction death of the lifting contactor,it is an effective method to prevent jacking accident of crane.
