ABSTRACT:
A hub for a wind turbine with a first end facing a nacelle of the wind turbine and a second end facing a direction opposite the nacelle. The hub has at least one opening between the first and second end, which opening is adapted for receiving a wind turbine blade, and the hub is adapted to rotate in relation to the nacelle by means of the wind turbine blade. A self-supporting front structure is connected to the second end of the hub, the front structure extending from the second end of the hub and away from the nacelle and being arranged to support a spinner module, the spinner module being adapted to house the front structure and hub. The front structure has a projecting part, which is part of the self-supporting structure and can extend from the front structure and away from the nacelle and has a connection point.
