Theoretical and experimental analysis of the main girder double girder bridge cranes
Delić et al. · International Journal of ADVANCED AND APPLIED SCIENCES · 2019
When designing cranes, it is necessary to analyze the value of the contraction of the construction, as well as the values of the maximum stresses occurring in the crane construction.Precisely, in this paper, the theoretical and experimental analysis of the contraction and stress condition of the main crane girder in accordance with the standard of crane-general design has been done.The analysis of mechanical appearance in the main girder of the crane is carried out on the basis of the analytic solution of equilibrium equations.The results obtained by the theoretical analysis of the main crane girder were verified by experimental tests on the model of a double girder bridge crane with a capacity of 250 kg.At the end of the work an analysis of the obtained results was performed, on the basis of which specified conclusions were made.
