The article represents modeling and calculation of reliability and durability of an existing element of a mechanical system-the load-carrying structure of the main beam of a metallurgic traveling crane. It is admitted that the criterion determining the reliability and durability of the equipment is the value of the permanent elastoplastic distortion and the external and internal parameters of the system are subject to the normal distribution law. Based on the theory of runs, the values of distortion and durability of an active metallurgic traveling crane were calculated in relative units. The results of calculations are provided in the form of charts. The received data allow estimating the actual technical state of equipment at any lifecycle stage and taking appropriate managerial decisions aimed to provide industrial safety and decrease the construction risks.
