Abstract: The article presents the methodology and results of statistical modeling of vertical impacts from two four-wheeled overhead cranes on the crane beams of industrial buildings. For modeling, the materials of long-term experimental studies conducted in the storage spans of finished products of rolling shops were used as initial data. The simulation was carried out using Excel programs for calculating bending moments in crane beams and constructing histograms. The statistical characteristics of loading of crane beams of typical spans located in the zone of intensive crane operation are obtained. The actual load of crane beams in comparison with the calculated assumptions is revealed. Recommendations for the study of vertical impacts from multi-wheeled overhead cranes operating mode 7K on crane beams and columns of industrial buildings have been developed.
