Abstract

See full text

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.
