Tower crane is one of the vertical transport machinery widely used in the construction at present. Due to its own structure and safety management defects, accidents often occur and have serious consequences [1]. Therefore, it is of great significance to study the safety accidents of tower crane. In this paper, through a large number of accident statistical analysis and expert interviews, from the analysis of the entire process of tower crane installation, use and disassembly stage, the accident tree with the tower crane safety incident as the top event is established. Through the qualitative analysis of the accident tree, the minimum cut (diameter) set is obtained, on this basis, the structural importance of all basic events is sorted, the main factors affecting the safety accident of the tower crane are determined, and the corresponding management and control are proposed, and provide a basis for preventing tower crane accidents and controlling tower crane risks.
