Abstract
A method of handling the pitch bearing unit of a rotor blade mounted to the hub of a wind turbine, the method including the steps of providing an extension assembly at the interface between the rotor blade and the hub, moving the rotor blade outward from the hub by means of the extension assembly to open a gap large enough to accommodate the pitch bearing unit while maintaining a connection between the rotor blade and the hub, and removing the pitch bearing unit through the gap.

A method of handling a pitch bearing unit of a rotor blade mounted to a hub of a wind turbine, comprising:
- providing an extension assembly at an interface between the rotor blade and the hub;
- moving the rotor blade outward from the hub by means of the extension assembly to open a gap large enough to accommodate the pitch bearing unit while maintaining a connection between the rotor blade and the hub;
- and
- removing the pitch bearing unit through the gap.
A pitch bearing unit handling arrangement, comprising an extension assembly at an interface between a wind turbine hub and a rotor blade, configured to move the rotor blade outward from the hub to open a gap large enough to accommodate the handling of a pitch bearing unit while maintaining a connection between the rotor blade and the hub.
