| Abstract: | The saddle-shaped end beams of the trolley structure of a 150 t metallurgical crane, which had been in use for 10 years, came to have a lot of visible cracks. In light of this, the dynamic stress in the trolley structure was tested and analyzed, and the general stress condition of the trolley structure was calculated with FEM. Based on the results, a plan for the structure reinforcement is presented. |

| Keywords: | trolley structure crack stress testing reinforcement |
