ABSTRACT:
The invention relates to methods of handling wind turbine blades and mounting said blades on a wind turbine, said method comprising the steps of lifting a wind turbine hub to the nacelle of wind turbine with a lifting system and mounting the hub on the nacelle. Further, the method comprises the steps of gripping at least one wind turbine blade with a lifting system including at least one gripping unit for handling wind turbine blades, lifting said at least one wind turbine blade into close proximity to said hub, and mounting said at least one wind turbine blade on said hub. The invention also relates to a gripping unit for handling a wind turbine blade during transport.
