  • Understanding Overhead Crane Deflection and Criteria -

    2014-12-23u2002·u2002Horizontal deflection is a maximum deflection ratio allowed for a bridge crane or runway. For regular bridge cranes, this value is usually L/600. For a Workstation Bridge Crane, the value is greater (L/400). In the absence of more detailed calculations, it is acceptable to assume that the top flange resists the whole horizontal force.
