Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention. It is to be understood that the described embodiments are merely a few embodiments of the utility model, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

In fig. 4, above the spreader 7, there are arranged counterweight assemblies 7-8, and by adjusting the positions of the counterweight assemblies 7-8 on the spreader 7, an adjustment of the centre of gravity of the spreader 7 can be achieved.
The utility model discloses a wind turbine generator system cabin hoist device's theory of operation as follows:
referring to fig. 2, 3 and 5, the nacelle 1 includes three parts, namely a rear nacelle roof 1-1, a lower nacelle roof 1-2 and a front nacelle roof 1-4, and four openings 1-3 are respectively arranged on two sides of the front nacelle roof 1-4;

a rear frame lifting lug 3-1 is arranged on a rear frame 3 of the engine room 1 and is used for being connected with a lower hanging strip 7-5;
when the engine room is integrally hoisted, the integral hoisting of the engine room can be completed only by opening the openings 1-3 on the engine room top cover 1-4 at the main transmission chain component 4 and matching with the hoisting tool 7. At this time, 8 is the center of gravity position of the integral hoisting of the engine room;
the front lifting point at the position 2 of the cabin split lifting appliance is the same as the whole lifting appliance of the cabin, and the rear lifting point at the position 2 of the cabin split lifting appliance is connected to the position of a lifting point 5-1 of a frame 5 in the cabin;
