1, the car load stop at the side of the rigid leg cantilever end. Calculate the maximum rigid leg support reaction force. If there is no boom is fully loaded car parked in the center of the rigid leg.
2, a rigid leg channel formed by the two sets of uprights. bridge gantry crane recommends either of two directions of a group strut stability calculation. The maximum load for the rigid leg support reaction force. Bending moment and shear by another group of columns to balance (can not be counted). This is a simplified calculation method is convenient and safe.
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.
