The wind turbine tower is very large, usually with a diameter of more than 10 meters, and the corresponding weight is also very large. The wind turbine tower is a cylindrical cylinder with flanges coaxially arranged at both ends. There are multiple mounting holes evenly spaced along the circumference of the flange, and the distance between any point on the mounting hole and the centerline of the tower is less than the inner radius of the tower.

[0003] During production, wind turbine towers are generally produced in sections and assembled into a complete wind turbine tower at the installation site.
