An analytical estimates of plasto-elastic deformation of the bearing construction of the metallurgical crane. In these uses probabilistic method of synthesis of conversion probabilities for the mechanical system, in which the main processes determining its durability, are the processes of fatigue and plastic and elastic-plastic deformation and buckling. Are the factors influencing the process of fatigue in metallurgical of bridge cranes. The proposed method is brought to the numerical results for the existing пятидесятитонных cranes of metallurgical production. Obtained failure of a mechanical system due to the growth of residual deformation and increase the deflections of above permitted and is equal to P(h-e)=0,457. The obtained data are consistent with the known data of risks of metallurgical enterprises of the various elements that says about the legality of this approach to the forecasting and assessment of the reliability of the load bearing construction of bridge cranes metallurgical enterprises.The assessment of elastoplastic deformation allows to Supplement the theory of structural risk analysis by the method of conversion of probability and its further development with the aim of preventing accidents and industrial safety management of complex technical systems.
