“…When designing a dump truck (DT), the parameters and characteristics of the components of the hydraulic system (HS) are to be determined [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. The HS of a modern DT includes many elements, the characteristics of which are interrelated with each other.…”

At the initial stage of designing a dump truck it is necessary to determine the main units and assemblies of the vehicle, their parameters and dimensions. One of the systems of the dump truck is the hydraulic system. When creating new dump trucks, there is a necessity to define parameters and characteristics of hydraulic system components. The peculiarity of quarry dump trucks, in contrast to dump trucks, which are used on public roads, is that the modes of their operation are different. Therefore, when creating new dump trucks, it is necessary to develop an algorithm for selecting and justifying the parameters of the hydraulic system at the early stages of design. The article substantiates the necessity of developing an algorithm for determining the parameters of the hydraulic system. The main hydraulic consumers are defined and the requirements of each of the consumers are presented. The algorithm of justification of the parameters of the hydraulic system of the quarry dump truck is described. Determination of the required pump capacity of the hydraulic system is described. The use of the described algorithm for justification of the hydraulic system parameters of the dump truck contributes to the reduction of terms of development of design documentation at the early stages of design.

At present, Kuzbass coal strip mines pay great attention to improving quality performance of mining equipment operation, including reliability and durability of components and units. One of the ways of the performance improvement is decreasing number of unforeseen failures. To achieve this purpose a mine dump truck part diagnostics should be introduced into a maintenance service procedure. At the same time the process of diagnostics should not increase the machinery downtime, but effectively reveal a condition of motor-wheel gearboxes in the course of dump truck operation. The aim of the research is to increase the reliability and service life of motor-wheel gearboxes of large BelAZ dump trucks. Failure of a motor-wheel gearbox is a rare phenomenon, but the cost of a new gearbox can vary from 3.5 to 10 million rubles. That is why it is important to implement such methods of diagnostics, which allow revealing the condition of gearboxes in the shortest possible time and without disassembling corresponding units. Determination of the actual technical condition of motor-wheel gearboxes is possible by different methods: vibroacoustic; acoustic; thermal; physical and chemical analysis of spent operating materials. The studies showed that none of these methods can be used as a universal one. When justifying and selecting the most suitable method, different factors should be considered, including technological, or a combination of methods should be applied, which will reduce risks, but at the same time increase costs. It is necessary to develop a better diagnostic method based on the use of several methods simultaneously.
