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 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 detaching or installing a rotor blade from or to a hub of a wind turbine includes positioning the rotor blade toward a ground location between a three o'clock position and a nine o'clock position. The method also includes mounting a mechanical arm to an uptower location of the wind turbine. Further, the mechanical arm includes a torqueing tool at a distal end thereof. Thus, the method also includes removing or installing, via the torqueing tool, each of the plurality of hub fasteners so as to detach or attach the rotor blade from or to the hub.

Abstract: A rotor turning device for balancing a rotor secured atop a tower of a wind turbine during installation and/or repair of one or more rotor blades of the wind turbine includes a hydraulic drive mechanism for operably engaging with a brake disc of the wind turbine. The brake disc is positioned adjacent to a gearbox of the wind turbine. The rotor turning device also includes a mounting device for securing the rotor turning device adjacent to the brake disc of the wind turbine. Thus, when the hydraulic drive mechanism engages the brake disc, the rotor is rotated to a desired position so as to position one or more rotor blades of the wind turbine in a balanced configuration.

Abstract: A method for replacing an existing generator frame that supports a generator of a wind turbine includes removing the generator from atop the existing generator frame. The method also includes dismounting a control cabinet of the wind turbine from the existing generator frame. More specifically, the control cabinet is electrically connected to one or more wind turbine components via a plurality of cables. The method further includes relocating and securing the control cabinet to an uptower location within a nacelle of the wind turbine with the plurality of cables remaining electrically connected. As such, the method includes removing the existing generator frame from within the nacelle. Moreover, the method includes installing a new generator frame in place of the removed existing generator frame. Thus, the method also includes remounting the control cabinet to the new generator frame.
