Objective: a numerical model of a rail-mounted mobile boom crane was developed to determine the stress- strain state of the main load-bearing components of the metal structure within a three-dimensional non- stationary framework. Methods: computer-based simulation and numerical experimentation. Results: the dynamics of crane loading regimes associated with oscillations of a flexible load suspension induced by uneven settlement of ground supports and by transformations in the core of the support contour. Practical Significance: the proposed mathematical model of the rail-mounted mobile boom crane facilitates numerical investigation of the stress-strain behaviour of its structural elements in a three-dimensional non-stationary framework.
