Abstract
A wind turbine generator nacelle (14) comprises a nacelle frame (44) having a first forward hub end and a second aft end. Dedicated transport fittings (46) are positioned at each of the ends of the nacelle frame (44). The fittings (46) are adapted to be engaged by transport frames (86) on first and second transport trailers (80) for supporting the nacelle frame (44) for transport by the trailers (80). A service platform (20) is mounted to the transport fittings (46) on the aft end of the nacelle frame (44) such that the service platform (20) is cantilevered off of the aft end of the nacelle frame (44).

A nacelle of a wind turbine generator, comprising:
- a nacelle frame having a first forward hub end and a second aft end;
- dedicated transport fittings at each of said ends of said nacelle frame, said fittings adapted to be engaged by transport frames on first and second transport trailers for supporting said nacelle frame for transport by the trailers;
- and
- a service platform mounted to said transport fittings on said aft end of said nacelle frame such that said service platform is cantilevered off of said aft end of said nacelle frame,
- wherein said nacelle includes an internal service floor and wherein a floor of said service platform is coplanar with said internal service floor.
A method of transporting a nacelle of a wind turbine generator to an installation site and configuring it for use at the installation site, comprising:
- providing the nacelle having a nacelle frame having a first forward hub end and a second aft end;
- providing dedicated transport fittings at each of the ends of the nacelle frame;
- engaging the transport fittings on the first forward hub end of the nacelle frame with a first transport frame on a first transport trailer and engaging the transport fittings on the second aft end of the nacelle frame with a second transport frame on a second transport trailer;
- supporting the nacelle above the ground with the first and second transport trailers;
- transporting the nacelle to the installation site with the first and second transport trailers;
- removing the nacelle from the first and second transport trailers;
- and
- mounting a service platform to the transport fittings on the second aft end of the nacelle frame such that the service platform is cantilevered off of the second aft end of the nacelle frame,
- wherein the nacelle includes an internal service floor and wherein a floor of said the service platform is coplanar with the internal service floor.
