Abstract: The present disclosure is directed to a lift system for a rotor blade of a wind turbine. The lift system includes a lifting device having at least one cradle. The cradle has a profile that corresponds to at least one of the exterior surfaces of the rotor blade so as to support at least a portion of the rotor blade. Further, the lift system includes a positioning assembly having at least one distance sensor mounted to the hub and at least one visual sensor mounted to the lifting device. Thus, the distance sensor is configured to identify a distance from the hub to the lifting device and the visual sensor is configured to identify a position of the rotor blade in the cradle.

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.
