Abstract
A method for mounting a rotor to a drive shaft of a wind turbine, the method comprising placing a hub on a surface, attaching a first, a second, and a third rotor blade to the hub to thereby make a rotor in situ. To protect the blades and to avoid fixed lifting lugs on the rotor, the method includes the step of wrapping a sling about each of the blades, attaching each sling to a fitting, lifting each fitting to thereby raise the rotor from the surface, and attaching the rotor to the drive shaft while the position and orientation of the rotor is controlled by the slings.
