Description
Technical Field
[0001] The utility model relates to the technical field of wind power installation, in particular to a rotating hook used for wind power installation. Background Art
[0002] Wind turbine installation refers to the transportation of wind power equipment (such as blades, towers, generators, converters, etc.) to the designated location, and the installation of the wind turbine on a pre-prepared foundation through a series of processes such as hoisting, electrical installation, and debugging.
[0003] The installation process needs to strictly follow the operating procedures to ensure the safety of personnel and equipment. After the installation is completed, grid connection testing and acceptance are required to ensure that the wind turbine can be normally connected to the grid for power generation.
[0004] During the entire process, operation and maintenance work is also required to ensure the stable operation and efficient power generation of wind turbines.
[0005] The wind power installation rotating hook is a special lifting device used in the installation process of wind turbines. It is usually installed on the boom of a crane and can rotate 360 degrees. The main function of the rotating hook is to provide more flexible positioning and adjustment capabilities when lifting the various components of the wind turbine.
