Huge projects with large-scale , high- investment , long construction period , technical complexity , uncertainty factors to ensure that the schedule for completion of the project , control investment to ensure the quality of the project , and the rapid formation of production capacity , thereby increasing the economic benefits of the project is the main objective of the project construction . Tower crane is a commonly used construction machinery in China 's industrial and civil construction , huge projects , the group tower construction is very popular due to its inherent risk , the construction site of the tower crane caused an accident occurs . Both in theory and practical work , our tower crane safety risk management , the lack of a comprehensive summary and in-depth analysis , therefore , the safety management of the tower crane control important in the whole process of construction projects . -Depth study of the construction work in the tower crane accident risk and its mechanism and frequency to minimize and avoid the occurrence of the tower crane accident , reduce the construction industry casualties , to speed up the progress of the project , the key to improve the quality of the project . Relying on this article Hongqiao integrated transport hub in the West Terminal project quality and safety management \the risk factors , the use of accident causation theory model of the causal chain , starting from the identification of sources of risk , by statistical analysis of the number of engineering case to identify the cause of the accident tower crane , abstract commonalities , identify tower crane construction may occur significant risks , to establish tower crane construction risk classification table , and a variety of risk characterization and risk analysis , come to a variety of factors led to the construction injury accident frequency of various risk factors for causal analysis . And then , depending on the risk category , to study the appropriate risk control countermeasures . Thesis accident causal chain \the subsequent huge engineering construction provides case reference.
