Design Modification & Analysis on Girder of EOT Crane

Girder is the important component of E.O.T Crane which is used for handling and transporting the vertical loads. In RSM of BSP 13 & 26 m rails are manufactured but the end carriage is designed for 13 m rails and due to this end carriage are overloaded with 26 m rails also. Due to this causes, cracks developed on runway girder, wheel and motors. The main purpose of the present study is to avoid crack propagation in the crane girder by decreasing the stress concentration factor. To decrease the stress concentration factor, design of crane girder is slightly modified by providing fillets at the sharp edges and also load analysis performed on girder to find the load safe load bearing capacity. After preparing the 3D CAD Model of girder it is exported to Solid works software to find out the result by FEA analysis. After a comparison of the finite element analyses and the analytical calculations, the analysis was found to give the most realistic results.
