Abstract: A nacelle for a wind turbine and a method for erecting a wind turbine are disclosed. The nacelle comprises a main unit arranged to be connected to a wind turbine tower, via a yawing arrangement, and at least one side unit mounted along a side of the main unit in such a manner that direct access is allowed between the main unit and the side unit(s), each side unit accommodating at least one wind turbine component, and at least one side unit being capable of carrying the wind turbine component(s) accommodated therein. The main unit and at least one of the side unit(s) are distributed side by side along a substantially horizontal direction which is substantially transverse to a rotational axis of a rotor of the wind turbine. A sufficient interior space of the nacelle is obtained while allowing the nacelle to be transported due to the modular construction. The weight of the wind turbine components is arranged close to the tower due to the transversal arrangement of the side unit(s) relative to the main unit.

Abstract: A more efficient and simple wind turbine generator with a lifting device and method of using the lifting device is disclosed. A wind turbine generator comprises a tower, a nacelle supported by the tower, the nacelle comprising a foundation supporting components of the nacelle, a yawing system comprising a yaw bearing enabling rotation of the nacelle relative to the tower, a lifting device internally in the wind turbine generator and capable of moving an item, a support supporting the lifting device, and wherein the lifting device is moveable in a horizontal direction from a first position to a second position, and at least one of the positions is, in a vertical direction, between a lowermost level of the foundation, such as just above the yaw bearing, and an uppermost level of the tower, such as just below the yaw bearing.

Abstract: A nacelle (2) for a wind turbine (1) and a method for erecting a wind turbine (1) are disclosed. The nacelle (2) comprises a main unit (8) arranged to be connected to a wind turbine tower (3), via a yawing arrangement, and at least one side unit (9a, 9b, 9c, 9d) mounted along a side of the main unit (8) in such a manner that direct access is allowed between the main unit (8) and the side unit(s) (9a, 9b, 9c, 9d), each side unit (9a, 9b, 9c, 9d) accommodating at least one wind turbine component (13, 14, 15, 16, 17), and at least one side unit (9a, 9b, 9c, 9d) being capable of carrying the wind turbine component(s) (13, 4, 15, 16, 17) accommodated therein. The main unit (8) and at least one of the side unit(s) (9a, 9b, 9c, 9d) are distributed side by side along a substantially horizontal direction which is substantially transverse to a rotational axis of a rotor of the wind turbine (1).

Abstract: A handling system for a wind turbine nacelle in connection with self-loading or self-unloading of the nacelle to or from a vehicle. The system comprises two or more lifting apparatus, where the lifting apparatus are engaged with lifting areas of a load carrying structure of the nacelle. The lifting areas are a part of the load carrying structure or are integrated in the load carrying structure, and where the lifting apparatus lifts by applying linear force to the load carrying structure of the nacelle. The invention further relates to a method for vertical displacement of a wind turbine nacelle and a wind turbine nacelle prepared for self-loading or self-unloading to or from a vehicle.
