Abstract
The invention is a frame for carrying a load in a wind turbine. The frame comprises a first and a second beam extending in a lengthwise direction, a third beam extending in a transverse direction between a first joint on the first beam and a second joint on the second beam. The third beam is configured for carrying the load. The frame further comprises a stress-inducing cross-shaped structure forming four legs joined at an intersection and extending therefrom towards four ends, where two of the four ends are attached on opposite sides of the joint on the first beam and the other two of the four ends are attached on opposite sides of the joint on the second beam. To prevent excessive deflection of the third beam and of the cross-shaped structure, the cross-shaped structure is decoupled from the third beam and therefore allowed to move e.g. without touching the third beam.
