A structural strength and integrity assessment method of a portal crane was proposed in this paper.According to drawings and practical measurements,a three-dimensional CAD model was built and imported into finite element software ANSYS,then based on actual working conditions reliable constraints and loads were imposed on the meshed model,afterwards structural strength was approached by static stress analysis.In order to verify the results of finite element analysis,experimental stress analysis was advanced.Non-destructive testing was applied in some important welding region to assess the structural integrity.Finally,according to these results,the safety properties was achieved,and then some recommendations was advanced to improve the safety of this portal crane.
