Problems of modelling of dynamic loads acting on cranes caused by driving over uneven rails

The article reviews the standards and literature describing the issue of determining dynamic loads acting on crane caused by travelling on uneven surfaces, the knowledge of which is essential for proper dimensioning of the supporting structures of cranes, in particular cranes for working at high movement speeds. It presents the factors significantly affecting the value of these dynamic loads. The article also demonstrates selected dynamic models of cranes and methodology of their building. Presented are the similarities and differences in the modeling of dynamic loads. Calculated values of the dynamic coefficients as well as discussion of the results are presented.
