The following tooling is specially designed to avoid major safety hazards to customer equipment such as main shaft drops, hub drops, blade damage, tower crash, and even casualties. After the installation of the main shaft special tools, the customer can remove the shutdown or power curtailment requirement of the turbine with primary and secondary defects and recover production loss.

This special tools can meet the following objectives during the daily operation and maintenance of the turbine:

The center of gravity nacelle and tower vibration frequency change is limited, do not affect other main components;

Reliability and safety: It can withstand the impact load 

caused by main shaft broken at full rated power;

The impact load generated when the main shaft is broken

 can ensure the safety of the tools and the connecting 

structure of nacelle (bed plate, bearing housing)

No major modifications will be made to the nacelle ;

Modular design;

Lightweight design;

The design of other tools for nacelle inside installation 

is considered;

Reduce labor intensity and improve installation efficiency

Take into account the operation requirements of normal temperature and low temperature wind farm (-30℃)
