Background In the field of wind power generation, the replacement work of a generator in a fan cabin is an important part in fan maintenance work. Currently, large lifting facilities are commonly used to accomplish this task when generator changes are performed. With the continuous development of the wind power industry, the installed capacity of the fan has an increasing trend. The increase of the installed capacity of the fan enables the height of the fan to be continuously increased. This change presents new challenges for the replacement work of the generator.
