However, there are certain safety risks in the process of crane lifting operation. If the quality of lifting operation is not well controlled, a large safety accident is likely to occur, and serious accidents will induce the safety of staff's life and property. Therefore, this paper focuses on the lifting operation safety risk analysis, and put forward effective control measures for reference.展开更多
