Abstract: A system for enabling servicing of a rotor of a wind turbine has a rotor blade sling with at least one strap configured to be placed over the top of a rotor blade in a ten o'clock position or a two o'clock position. One or more rigid bars extend from the hub and out away from the hub, and the one or more rigid bars are coupled to the at least one strap. One or more support straps are coupled to the at least one strap, and the one or more support straps are configured to couple and support a rotor blade in a six o'clock position.

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.

Abstract: A method of replacing a wind turbine blade includes connecting a plurality of first hoisting devices between a wind turbine support hub and the wind turbine blade, suspending the wind turbine blade from the wind turbine support hub through the plurality of first hoisting devices, connecting a plurality of second hoisting devices between the wind turbine support hub and the wind turbine blade, supporting the wind turbine support blade with the plurality of second hoisting devices, disconnecting the plurality of first hoisting devices from the wind turbine blade, and lowering the wind turbine blade to the ground.
