technical field

The utility model belongs to the technical field of fan hoisting, in particular to a wind power generation tower translational hoisting system.

Background technique

Wind energy is an important resource to help humans reduce carbon dioxide emissions and reduce dependence on fossil fuels. To make better use of wind energy, wind turbines are the foundation. In recent years, my country has paid more and more attention to wind power projects, and the number of new power generation towers is increasing every year. The height of wind turbines is generally more than 80 meters, and a single piece of equipment is relatively heavy. At present, the hoisting method of wind turbines generally adopts large-tonnage crawler cranes or truck cranes, and cooperates with small-tonnage truck cranes to hoist the fan nacelle and blades. It is difficult to transport these large cranes to the site, and the requirements for the roads along the line are also high. The assembly cycle is relatively short. It is long, the workload is heavy, and the rental fee is also quite expensive. With the development of wind power generation to the Gobi Desert, mountainous areas, and seas, its construction is more difficult. Therefore, the call for automation in wind turbine assembly is getting higher and higher.
