Abstract
With the rapid development of wind power generation technology, tower cranes, as the key equipment for wind turbine lifting, are widely used in the installation process of wind turbines due to their high lifting height and strong load carrying capacity. This paper analyzes the stability factors of tower cranes in the process of wind turbine lifting through the study of tower crane stability, the structural stability of tower cranes and the stability of the whole machine, especially the influence of wind load, lifting weight, tower foundation design and other factors on its stability. The main contents include static stability of tower crane, dynamic stability under wind load, special stability problems in the process of wind turbine lifting, and measures to prevent tower crane tipping are proposed. In addition, combined with the current research situation at home and abroad, this paper also looks forward to the development trend of tower cranes in the field of wind power lifting, such as wind load research, dynamic modeling and simulation technology, monitoring and control technology.
