AI Technical Summary
Technical Problem
Existing methods for hoisting wind turbine towers are prone to problems such as deformation of the top of the tower or insufficient hoisting height during the hoisting of large wind turbine generators.
Method used
The wind turbine tower is hoisted from the top using a balance beam. By combining upper and lower hoisting supports, multiple upper and lower hanging shaft sleeves are added, the position of the slings is adjusted, and anti-loosening bolts and sleeve structures are used to improve the safety and applicability of the hoisting process.
Benefits of technology
This reduces the risk of deformation during the hoisting of wind turbine towers, ensures the required hoisting height, and enhances the applicability and safety of the hoisting equipment.
