There are no problems in front of us.
The problem: Because of the incorrect preload after mounting, the blades of the wind turbine vibrated when it worked in bad weather, reduced wind turbine's life.

CHG's solution: Our technicians had a long-time technical exchange with foreign design experts of wind turbine, and then they found the relationship between preload and load moment, as a result, they solved the problem of blades vibration; prolong the life of wind turbine.
