Wind turbine nacelle, transport system for a wind turbine nacelle and method for transporting a wind turbine nacelle

1. A transport system for a wind turbine nacelle, comprising:

a first trailer;

a second trailer;

a first leg arrangement attached directly to a front end of the nacelle;

a second leg arrangement attached to a bottom portion of the nacelle; and

a bridge assembly interconnecting the first trailer and the second trailer and fixed to the first leg arrangement and to the second leg arrangement to define a stable frame suspended between the first trailer and the second trailer for the nacelle.

2. The transport system according to claim 1 , wherein the bridge assembly comprises a first longitudinal beam and a second longitudinal beam arranged substantially parallel to one another, and wherein at least one of the first leg arrangement and the second leg arrangement is fixed in between the first longitudinal beam and the second longitudinal beam.

3. The transport system according to claim 2 , wherein the at least one of the first leg arrangement and the second leg arrangement is fixed in between the first longitudinal beam and the second longitudinal beam by a form fit.

4. The transport system according to claim 2 , wherein at least one of the first longitudinal beam and the second longitudinal beam is a beam comprising, at least at one position in a cross section, an upper end section, a lower end section and a middle section between the upper and lower end sections;

wherein at least one of the upper end section and the lower end section has a larger horizontal extension perpendicular to the longitudinal extension of the beam than the middle section so that the at least one of the first leg arrangement and the second leg arrangement is disposed in a region of the middle section in between the upper end section and the lower end section.

5. The transport system according claim 2 , wherein the at least one of the first longitudinal beam and the second longitudinal beam is a beam with a middle section having at least one opening into which an end of one of the first leg arrangement and the second leg arrangement fits.

6. The transport system according to claim 2 , wherein the second leg arrangement is fixed between the longitudinal beams via insertion into orifices of the longitudinal beams.

7. The transport system according to claim 1 , wherein the bridge assembly comprises a cross beam orientated essentially perpendicular to a longitudinal extension of the bridge assembly.

8. The transport system according to claim 7 , wherein the cross beam is, in an assembled state of the bridge assembly, positioned such that at least one of the first leg arrangement and the second leg arrangement is positioned on the cross beam.

9. The transport system according to claim 8 , wherein the cross beam is positioned such that the first leg arrangement is positioned on the cross beam.

10. The transport system according to claim 1 , wherein the bridge assembly comprises a plurality of separate construction parts which are detachably interconnected in an assembled state.

11. The transport system according to claim 1 , wherein the first leg arrangement further includes a frame part projecting away from the front end.

12. The transport system according to claim 1 , wherein the second leg arrangement is partially inserted into an opening in the bottom portion of the nacelle.

13. The transport system according to claim 1 , wherein the first trailer and the second trailer are operably connected to a tractor for pulling of the first and second trailers.
