The system of the preventive maintenance (PM), accepted at production association LLC KINEF, taking into account safe operation and health assessment, is analyzed. Statistical data of results of diagnostics are processed; options of the increase of the integrated reliability indicator of the system of pipeline transport are offered. The trend lines of a condition change of the pipeline in time and the approximate curves of diagnostic data of nondestructive inspection technique with creation of the long-term forecast of its technical condition was constructed. The option of correction of the accepted PM system with the analysis of quantitative change of an indicator of reliability was developed, by which application of the percentage of uptime will increase from 0.909 to 0.957.

Modern industry in the XXI century requires high-performance and fully automated technology. The best way to meet these requirements is the introduction of new progressive technologies in the process of transportation. One of the possible ways to increase productivity, as well as automate the process of transportation, is the transition from cyclic machines to continuous transport, namely to belt conveyors. However, with the increase in the length of the conveyor there is a need for stronger belts. This can be avoided by using intermediate drives of various designs. The article describes the principle of operation of the intermediate linear drive with transverse partitions, provides formulas for calculating the values of the tractive effort, gives comparative graphs showing the effectiveness of the use of an intermediate drive in various conditions. The possibilities of increasing the capacity of an intermediate linear drive are described.

This paper analyzes the possibility of using electric vehicles as a controlled distributed generator. Aggregation of demand and supply for electric power with the participation of batteries allows us to solve the problem of the development of the electric grid infrastructure of megacities. The absence in some areas of the city of opportunities for technological connection of consumers and significant deterioration of the network infrastructure is solved by the integration of electric vehicles in the city's power system. The article shows that information technology allows you to control the energy curve over time. At the same time, the power schedule in the loaded power centers will be deprived of pronounced highs and lows, which favorably affects the loading of generating capacities. Informatization of electric transport and the use of a digital platform will eventually become part of the concept of "smart city".
