Abstract

To facilitate transport and assembly during the erecting of wind power plants, a two-part base frame is proposed for the azimuthal adjustment of the gondola on the tower of the wind power plant, the lower part of which 16 has the azimuthal drive device 23 and the upper part 6 of which has the drive train 1, 2, 12, 13, 14. Both parts are pre-assembled at the factory, set onto the tower, and screwed tight onto each other at their connection point 15.
