Specific embodiment 1:
[0038] The present invention will be described in detail below by taking the hoisting of a large generator stator as an example.
[0039] Figure 1 to Figure 8 It constitutes the specific embodiment 1 of the present invention.
[0040] Reference Figure 8 The present invention uses a hydraulic jacking system to lift the stator from the inspection port of the main building, transport it horizontally and lower it to the top of its installation foundation to make it in place; it is characterized by the following steps:
[0041] 1) The hydraulic lifting device of the hydraulic jacking system is erected above the hydraulic jacking tower through a lifting beam, and connected to the hook by a steel rope. The hydraulic jacking tower is arranged above the two rails to form a whole Framework;
[0042] 2) After the stator is raised to the height of the platform by the hydraulic lifting device, the walking hydraulic jacking tower will send the stator to the top of the fou...
