Abstract:
A method for enabling servicing of a wind turbine rotor includes coupling a support cable to the blade root, the support cable extends from the blade root to a hub of the wind turbine. A lowering step lowers a rotor blade relative to the hub using the support cable so the rotor blade is spaced apart from the hub by an initial vertical distance. An installing step installs a rotor blade sling on the rotor, the rotor blade sling supports the rotor blade. Other steps are used for coupling the rotor blade to the rotor blade sling, lowering the rotor blade such that the rotor blade is spaced apart from the hub by a distance greater than the initial vertical distance, de-coupling the support cable from the blade root, and interposing a rotor servicing fixture between the rotor blade and hub. The rotor servicing fixture is configured to transport a rotor part.
