Problems of metallic crane structure deformability are considered. This paper contains results of experimental studies on deformability of overhead crane beam elements. These studies take into account the specific interaction between stresses arising from the product’s exposure to loads at various stages of its life cycle, from manufacturing to operation, and residual welding stresses. Recommendations are provided to help stabilize the dimensional parameters of a crane metallic structure.

“…The considered mathematical model is one of a range of the interconnected models allowing to estimate alternative options of redundancy and to choose the best one. For example, Baurova, Zorin, Prikhodko [24] suggest do this taking into account the influence of technological heredity when various materials are used for component production.…”

The main questions of ensuring reliability of cars by methods of redundancy are considered. The problematic nature of reliability factor is confirmed by the analysis. Redundancy method is reviewed as responsible for solution of the problem when opportunities offered at every stage of “car life time” are used. Three basic principles of repair arrangement based on redundancy method are presented. These principles serve to bring into effect working capacity inherent in a design. The new redundancy techniques with use of repair kits is offered. The feasibility of integrated redundancy system is developed.

In article questions of assessment of the risks arising in the course of design, production and operation of means of mechanization of construction using catastrophe theory are considered. In the course of operation of the machine malfunctions, suddenly defiant refusals of details gradually collect. The device of the theory of accidents allows to develop models of change of technical condition and operational properties of a details material for various service conditions. In the field of space of conditions of the system containing critical signs accident emergence conditions (refusal of a detail and an emergency) are created. Assessment of probability of emergence of refusal during a certain period of operation of the machine taking into account weight of consequences allows to establish risk level.
