Abstract: The article describes the regulatory requirements for extending the service life of general purpose bridge cranes, presents a numerical analysis of the stress-strain state of the span structure of the crane KM 20 and substantiates the recommendations for extending the service life of the crane. Strength analysis of the structure was carried out in the program environment APM FEM. By results of combinations of loadings of the crane the greatest concentration of stresses in an average part of span, and also in places of connection of the main beams with end beams are revealed. Calculation of deflections of the bridge at different loadings is carried out. The results showed that the classification group of the crane significantly effects the requirements for the maximum deflection of the structure, as well as the extension of the service life (final resource) of the machine, which is recommended to take into account when upgrading and reconstructing bridge cranes.
Keywords: crane, bridge, loading, stress-strain state, regime, service life.
