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 a system and method for lifting and/or removing a rotor blade to and from a wind turbine. In one embodiment, the system includes an up-tower pulley mounted on an up-tower location of the wind turbine, first and second ground winches, a pulley cable from the first ground winch over the up-tower pulley and attached to the rotor blade, a guide line attached between an up-tower location of the wind turbine and the second ground winch, a guide pulley mounted on the guide line, and a guide cable from the guide line over the guide pulley to the rotor blade. Thus, the guide pulley is configured to move along the guide line during lifting and removing of the rotor blade so that the guide cable can control an orientation of the rotor blade relative to the tower during lifting and removing of the rotor blade.

Abstract: A method and associated system are provided for removing a drive train component, such as a gearbox, from a rotor shaft uptower in a wind turbine, wherein the component is supported by transversely extending mounting arms at mount locations on the wind turbine frame. The drive train component is supported from above or below and the mount locations. At each mount location, a removal fixture is installed that includes an actuator that moves linearly essentially parallel to the rotor shaft. The mounting arms are simultaneously engaged with the respective actuators, which are controlled to linearly push the mounting arms until the drive train component disengages from the rotor shaft.

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.
