Since the generator 1 has a heavy weight which is even much larger than the weight of the spreader itself, by connecting the lifting lugs 2121 to different connecting positions 23, the position of the center of gravity of the spreader 2 in the loaded state and the unloaded state can be adjusted to maintain stable and smooth lifting. For example, when the center of gravity of the spreader 2 is changed after the generator 1 is unloaded, the lifting lugs 2121 can be connected to the unloaded lifting positions 232, so as to avoid that the generator 1 cannot be unloaded due to the change of the center of gravity.

After the generator 1 is installed, the lifting lug 2121 moves to the no-load lifting position 232 from the load lifting position 231, and the generator 1 is detached from the lifting appliance 2 after being fixed, so that the adapting structure 22 of the lifting appliance and the generator 1 do not interfere and collide during detachment, and the generator 1 is turned over and installed on the front support.

In some embodiments, the shackle bracket 2124 includes a runner 2126, the runner 2126 communicates with each shackle limiting end 2127, i.e., the load lifting position 231 and the empty lifting position 232, and the shackle 2121 moves along the runner 2126 from the load lifting position 231 to the empty lifting position 232.

Therefore, the installation position of the lifting lug 2121 on the lifting lug support 2124 can be adjusted according to the requirement of the installation angle of the generator 1, so as to meet the requirement of the turning angle of the lifting appliance 2 and the generator 1. In one embodiment, the first angle may be 90 °, and the second angle may be 96 °, but is not limited thereto.
