Lifting equipment is an important transport equipment in steel production,and workshop bridge steel structure is one of the important structural support lifting equipments. The gnawing rail and rail abnormal phenomenon appeared to a bridge crane of 450 tons soon after its use at a steel plant. 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 of the height difference of the adjacent track on the wheel-rail contact relationship,the finite element method was used to analyze the full load normal working conditions and the height difference between adjacent rails. The results show that the stress of the crane beam increased by 31. 03% and the total deformation increased by 52. 07% under different height of adjacent orbits. The quantitative analysis of the wheel-rail contact relation was presented.
