RWE has signed a Letter of Intent (LoI) with WindSpider. The Norwegian based company is developing a new modular self-erecting crane system, which surrounds the wind turbine tower like the web of a spider, and can be used on land as well as at sea.
The WindSpider solution uses the tower of the wind turbine as part of the crane and has an effective lifting capacity of more than 1,200 metric tons. The solution also has the potential to allow maintenance of floating wind turbines and the replacement of major components at sea.
