Abstract:
A handling system (11) for a wind turbine nacelle (3) in connection with self-loading or self -unloading of the nacelle (3) to or from a vehicle. The system (11) comprises two or more lifting means (15, 16) for displacing the nacelle (3) substantially vertically during the self-loading or self -unloading of the nacelle (3). The lifting means (15, 16) further comprises displacing means (28) for displacing the lifting means (15, 16) or apart of the lifting means (15, 16). Furthermore a method for transport of a wind turbine nacelle (3), a method for vertical displacement of a wind turbine nacelle (3) and use of a handling system (11) are disclosed.

A handling system (11) for a wind turbine nacelle (3) in connection with self-loading or self -unloading of the nacelle (3) to or from a vehicle. The system comprises to or more lifting means (15), where the lifting means (15) are engaged with lifting areas (14) of a load carrying structure (10) of the nacelle (3). The lifting areas (14) are a part of the load carrying structure (10) or are integrated in the load carrying structure (10), and where the lifting means (15) lifts by applying linear force to the load carrying structure (10) of the nacelle (3). Furthermore a method for vertical displacement of a wind turbine nacelle (3) and a wind turbine nacelle (3) prepared for self-loading or self-unloading to or from a vehicle are disclosed.

Abstract:
Mounting device for mounting or demounting a wind turbine blade (14) to or from a hub which is located on a nacelle at the top of a wind turbine tower (12). The mounting device comprises a sledge which comprises a support structure and a gripping structure. The support structure is adapted to releasably grip the wind turbine tower and adapted to guide the sledge along an outer surface of the wind turbine tower between a bottom end position and a top end position of the tower. The gripping structure is adapted to provide a releasable fixation of the wind turbine blade in a fixed orientation relative to the gripping structure. The sledge is adapted to be moved along the tower by a combination of the support structure and a cable connection to the top end. A tilt device (17) is arranged between the support structure and the gripping structure to facilitate tilting of the gripping structure relative to the support structure.
Abstract:
The invention relates to a support system for a wind turbine component with a rigid structure such as a wind turbine nacelle or a section of a wind turbine tower. The support system comprises a plurality of engagement mechanisms (6, 7, 8, 9) defining at least three corners, possibly at least four corners, of a surface. The surface, in case of the support system comprising at least four engagement mechanisms, is capable of forming a curved surface, and the surface, in case of the support system comprising at least three engagement mechanisms, is at least capable of being tilted in relation to e.g. a vertical orientation. Further, the invention includes a method for operating the support system by simultaneously operating the lower and upper telescopic actuator on each of the support systems, so that the wind turbine component can be lifted or lowered.
Abstract:
In order e.g. to increase safety, flexibility and simplicity when handling a wind turbine nacelle 104 compared to known solutions and devices there is disclosed a wind turbine nacelle 104 including a supporting structure 206, a nacelle housing 202 and at least four handling devices 501, 702 to be used when handling the wind turbine nacelle 104. The at least four handling devices 501, 702 are connected to supporting structure, and each of the at least four handling devices includes an integrated moveable part304. The integrated moveable part 304 is moveable between a first position 308 and a second position 402,and the integrated moveable part is inside or is flush with the nacelle housing in the first position 308 and is extending out of the nacelle housing in the second position 402.
Abstract:
According to the present invention is provided a wind turbine connected to a utility grid, said wind turbine comprising a nacelle, at least one transformer for feeding generated power to the utility grid, and a flexible suspension arrangement connected to a load carrying structure of the nacelle and suspending said transformer above a floor level of the nacelle.
Abstract:
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.
