    Abstract: A method for removing a rotor blade from a wind turbine may generally include installing a blade sock around an outer perimeter of the rotor blade, coupling a support cable to the blade root, lowering the rotor blade relative to the hub using the support cable, coupling at least one pulley cable between the rotor blade and a winch using at least one pulley, moving the pulley cable relative to the pulley to lower the rotor blade relative to the hub, applying a force through the blade sock as the pulley cable is moved relative to the pulley in order to control an orientation of the rotor blade and further lowering the rotor blade to a location on or adjacent to the support surface.

    Abstract: The present disclosure is directed to systems and methods for removing or installing a pitch bearing of a wind turbine. The method includes installing a first pulley block at an up-tower location of the wind turbine and configuring a second pulley block with the pitch bearing. A pulley cable is routed from a ground location over the first pulley block to the second pulley block such that the second pulley block is configured to slide along the pulley cable. The method also includes rotating the pitch bearing to a tilted position. Thus, the method further includes lowering or lifting the pitch bearing in the tilted position so as to prevent the pitch bearing from colliding with the tower.

    Abstract: The present disclosure is directed to a suspension system for a wind turbine rotor blade and methods for suspending said rotor blade from a hub thereof. The method includes positioning the rotor blade in a substantially six o'clock position. Another step includes removing at least one root attachment assembly from an adjacent rotor blade and providing at least one passageway from an exterior surface of the adjacent rotor blade to the root attachment assembly. Still another step includes inserting a cable through the passageway such that the cable engages an interior surface of the adjacent rotor blade and extends from within the adjacent rotor blade to the lowered rotor blade. The method further includes securing the cable to the rotor blade at an attachment location. Next, the method includes lowering the rotor blade a vertical distance from the hub until the blade is supported by the cable.
