Calculation of gantry crane flexible leg

   1, the car load stop at the side of the flexible cantilever leg end. Calculate the maximum support flexible leg reaction force. If there is no full stop at the car boom is flexible leg center.

      2, a flexible leg channel formed by the two sets of uprights. Struts its stability calculation in both directions. The maximum of  bridge gantry crane  load is flexible leg supporting forces.

      3, for the two directions of single limb strut slenderness ratio calculation. Allowable slenderness ratio: 150.

      4, calculated on the single-piece parts: such as: battens; connecting rod; plate;

      5, manufacture weld; installation welds.

      6,   hoist gantry crane   walking carts breaking legs when conditions force OK. The bending strength calculation.
