Abstract: When assembling,a large enough lifting platform is needed.Some mountainous construction is affected by the actual site of the construction site,and it is difficult to adopt the conventional ground assembly and overall lifting scheme.Special lifting tools have been used to carry out the air connecting and direct installation process of blades in a wind farm located in Qingyuan,Guangdong province.This paper has systematically summarized the technological process and operation points in the blade installation process for the wind turbine generator in the wind farm,and the high-altitude combination installation technology of blades is introduced.
