Selection of Bridge Crane Beam Optimization Parameters

: This paper is focused on the suitability of the selection of the parameters of the supporting structure of the bridge crane for the needs of cross-section optimization. The cross section of the beam is analysed in terms of its rigidity and dimensions with respect to the span of the crane. When optimizing to reduce overall weight, recommendations are given to address the issue of cross-sectional stability. An iterative procedure for the design of the cross-section of the beam at the specified load capacity of the crane and its span is proposed. In the article, only a theoretical analysis of the issue for the selection of suitable cross-section parameters of the crane girder for optimization needs is made, with the indication of another possible procedure for the optimization process itself aimed at minimizing the weight of the bridge crane girder.
