Abstract:

With the increase of the power of the onshore wind turbine, the height of the tower increases,and the difficulty of the tower hoisting construction increases accordingly. Taking the construction of awind farm in Subei County, Jiuquan City, Gansu Province as an example, this paper focuses on thefoundation bearing capacity of the hoisting platform, the lifting and unloading of the tower auxiliary craneand the installation and checking calculation of the main and auxiliary cranes during the hoistingconstruction of the wind power tower. The dynamic monitoring of the hoisting performance of the maincrane during the tower hoisting process is carried out,which effectively guarantees the safety andconstruction accuracy of the hoisting construction of the wind power tower.
