Abstract: In order to improve safety management level of tower crane installation and dismantling operation in construction, STAMP method was used to establish a model of such operation. Then, STPA method was adopted to analyze the model's safety from three aspects, namely component failure, interaction between components and external influence of the system, and 60 hazards were obtained and divided into 15 items of 6 aspects, including documents, personnel, mechanical equipment, management, external environment and process. Based on this, accident causes in 70 reports of tower crane installation and dismantling accidents were classified and analyzed. The results show that the hazards that should be paid attention to in safety management of tower crane installation and dismantling operation include lack of on-site supervisors or their neglect of duties, operation without license, lack of or unreasonable operation scheme, insufficient safety training and technical disclosure and incorrect process execution.

Key words: tower crane, installation and dismantling, systems-theoretic accident modeling and process (STAMP) method, system-theoretic process analysis (STPA) method, safety analysis
