Wind turbine overhaul of Nanao Island Wind Farm in Guangdong Province

Construction difficulties:Wind turbine hoisting and maintenance technology content is high, the operation is complex, offshore wind turbine maintenance is more difficult, undulating mountain roads and uncertain sea breeze is the biggest difficulty, to participate in the maintenance of lifting equipment is also a huge challenge, Nan'ao Island includes sizes37 islands, land area of 130.90 square kilometers, the island slope is steep, the road surface is narrow, the ruggedness can be seen in general, it is difficult to transfer equipment and takes a long time.

Construction process:What needs to be overhauled in this construction is the height20 storeys high, the blades are close62meters of wind turbines, passedSAC2600TRemove all the blade bolts of the wind turbine first, then remove the blades, overhaul the accessories, and then reload the blades for installation.

Testimonials:TrinitySAC2600T the lifting operation efficiency is very high, the transition is fast, the area is small, the wind power maintenance is very smooth, the original consideration is to use Zoomlion 400 tons for hoisting, but this road surface is too narrow, walking is not aspect, at the same time the construction site space is also limited, it will be very troublesome to carry out, and the cost is also larger. Considering the use of 260 tons is more convenient, at the same time, because the construction period is relatively fast, efficiency and safety are the basic guarantee for us to receive this single job, and finally the original plan takes 5 days to complete the construction period, and finally we will complete it in 4 days.
