The invention relates to a method for moving a wind turbine component, such as a wind turbine hub, from a transportation position to a wind turbine assembly position. The method comprises the steps of: attaching a handling unit to a structural part of the wind turbine component, operatively connecting the handling unit to a wire of a crane system, lifting the wind turbine component with the crane system to an assembly position of the wind turbine, the handling unit and the wind turbine component being suspended from a wire of the crane system, and rotating the wind turbine component with the handling unit during the lifting of the wind turbine component in order to orientate the wind turbine component for assembly. The invention also relates to a handling unit and a wind turbine hub and use hereof.
