Abstract：Lifting equipment is animportant transport equipment in steel production, and workshop bridge steelstructure is one of the important structural support lifting equipments.The gnawing rail and rail abnormalphenomenon appeared to a bridge crane of 450 tons soon after its use at a steelplant. In order to explore its causes, the elevation of the track was measured firstly.The height difference between adjacent orbits was found to be 59 mm.In order to investigate the influence ofthe height difference of the adjacent track on the wheel-rail contactrelationship, the finite element method was used to analyze the full loadnormal working conditions and the height difference between adjacent rails.The results show that the stress of thecrane beam increased by 31.03% and the total deformation increased by 52.07%under different height of adjacent orbits. The quantitative analysis of thewheel-rail contact relation was presented.
