Abstract
A lifting frame for lifting a transformer or reactor is provided that includes a frame wall section. The frame wall section extends within a frame wall section plane. A lifting opening is formed within the frame wall section, wherein a lifting opening axis is oriented normal with respect to the frame wall section plane. The frame wall section immediately surrounding the lifting opening has a thickness that increases with decreasing distance to the lifting opening axis. This construction allows for providing an edge of the lifting opening 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 generally reduces a contact pressure.
