Tower cranes are widely used in construction engineering. However, safety accidents often occur especially in the process of installation and disassembly. The paper analyzes the cause of a tower crane collapsed accident, to ifnd the key cause resulting in the accidents. The main cause of the collapsed accident is that serious weld defect exists in the tread weld of the standard section. And it also provides corresponding precautions, such as to strengthen speciifcation to the weld quality inspection, to standard safety management of construction, and to observe the rules for safe operation. The result has important significance for preventing and reducing the occurrence of accidents.
