Abstract: A method for making a nacelle and a nacelle for attachment to a wind turbine tower. The method comprising providing a main frame configured to form a load path from a drive train to the wind turbine tower, providing, on the main frame, a mounting structure for mounting a crane, providing a crane for mounting on the mounting structure, and mounting the crane to the mounting structure before the nacelle is attached to the wind turbine tower. The crane can then be used for assembly operation before the nacelle is attached to the wind turbine tower, e.g. at an assembly facility away from the tower where the wind turbine is erected.
