Lifting of transformer's active part is performed with a load-bearing element welded to the cover. The thesis consists of two parametric models: a volume model and a shell model. For the volume model's results analysis, the HSS method was used, which finds more correct solution in locally elevated stress concentrations. In the shell model, welds were also simplified with shell elements. The comparison between models show that the shell model does not show the same stress compared to the volume model. With the help of a volume model, a catalogue of dimensions of different load-bearing elements was compiled for two different materials.
