摘要
通过对桥式起重机使用环节事故类型的分析,建立其事故树,计算出桥式起重机使用环节事故树的最小割集及基本事件的结构重要度系数,并进行相对重要性排序,提出了相应的防范措施,能够为桥式起重机使用环节的事故预防提供依据。
Through the analysis of the type of accidents in the use of overhead travelling cranes,the accident tree is established,the minimum cut set of the accident tree of the overhead travelling crane and the structural importance coefficient of the basic events are calculated,and the relative importance ranking is carried out.Precautionary measures can provide a basis for accident prevention in the use of overhead travelling cranes,which helps to reduce the frequency of accidents in the use of overhead travelling cranes and the severity of accidents.
