According to the present disclosure a lifting frame for lifting a transformer or reactor is provided that comprises a frame wall section 100. The frame wall section extends within a frame wall section plane P. A lifting opening 104 is formed within the frame wall section 100, wherein a lifting opening axis x1 is oriented normal with respect to the frame wall section plane P. The frame wall section 100 immediately surrounding the lifting opening 104 has a thickness t that increases with decreasing distance to the lifting opening axis. This construction allows for providing an edge 106 of the lifting opening 104 with a comparatively large surface or contact area, while avoiding an overdesign of the frame wall section thickness. An increase in the surface of the edge 106 generally reduces a contact pressure.
