Abstract
The results of research and a development retrospective of the regulatory framework for the design and calculation of crane metal structures are presented. The cause-and-effect complex of bridge crane failures is considered, as well as research directions within the framework of the computational and experimental complex in the field of strength, reliability, dynamics, and analysis of the stress-strain state of fatigue strength are analyzed. The results of experimental fatigue studies of samples and models of crane structures are presented. The methodology of calculations for crack resistance and reliability is given on the example of the support unit of the end beam of a bridge crane
