    A 100 kN electrically operated crane (EOT) is provided on the gantry girder of an effective span of 8 m in an industrial buildings.  Now, another crane of capacity 50 kN hand-operated is provided on the same gantry girder used in some other industrial building. What would be the effective length (in m, up to three decimal places) of this gantry girder (on which 50 KN crane is provided) such that maximum vertical deflection allowed in gantry girder as per the codal provisions of IS 800:2007 remains same in both cases?
