Fit-Up Welding Rotator

The cylinder of the tower line is assembled by segments of a single cylinder. During the splicing process, the hydraulic assembly roller frame and cross welding operator are generally used to combine each other.

Hydraulic assembly roller frames are commonly used for welding long cylinders such as wind towers/cones. The alignment function uses four hydraulic cylinders to slightly adjust the center distance of the rollers, thereby driving the single section cylinder to tilt up and down, adjusting the height of the single section cylinder, and completing the alignment of the single section cylinder and the tower cylinder for spot welding alignment. According to the length of the cylinder, there are various combinations of hydraulic jack roller frames: fixing or moving the hydraulic jack roller frames, selecting the active and passive models and quantities of the roller frames after the assembly, and so on.

Hydraulic assembly and welding are generally completed inside the workshop, that is, the fabrication of long tower barrels is completed inside the workshop. For very high offshore wind power towers, it is sometimes necessary to conduct secondary splicing and welding at the wharf, requiring further large assembly and welding.
