In cases of severe weather such as strong winds, tower cranes are prone to tilting and fracturing, presenting a pressing engineering challenge regarding their repair. Taking a specific engineering project as an example, this study investigates the characteristics of repairing high-altitude tilting and fractured tower cranes, focusing on reinforcement, dismantling, and reinstallation techniques. Ensuring the safety of dismantling operations for tilted and fractured tower cranes involves initial reinforcement techniques such as reverse tensioning with steel wire ropes, rigid steel connection reinforcement, and welding reinforcement of fractured steel plates. Subsequently, the construction details of the roof hoist steel structure foundation and its connection with reinforced concrete structures are clarified, followed by the dismantling of the tilted and fractured tower crane and the installation of a new tower crane. Utilizing BIM technology enables comprehensive simulation of the entire process of repairing high-altitude tilting and fractured tower cranes, facilitating the adoption of innovative approaches to address construction challenges, thereby achieving cost reduction and efficiency improvement objectives. Additionally, attention is drawn to key considerations during construction, providing valuable insights and references for future projects aimed at repairing tilted and fractured tower cranes.
