Justification of the Number and Type of Tire Size for a Dump Truck with a Lifting Capacity from 90 to 130 Tons

Abstract

The article substantiates the quantity and type of tire size for a dump truck with a carrying capacity from 90 to 130 tons. Types of tire sizes for dump trucks are given, as well as an analysis of applicable tires for dump trucks. An example of tire configuration for a dump truck is described, as well as the differences between projects and dump trucks with the traditional arrangement of large tires. The working productivity of large tires was cal- culated using the TKH “tons per kilometer per hour” technique. The general tasks that need to be addressed when designing a dump truck are highlighted. The conclusion is made on the relevance of the development of scientifically based approaches when designing dump trucks. The above data indicate that when surface mining, it is possible to solve the economic problem of reduc- ing the operating costs of transporting minerals by applying the proposed arrangement and number of large tires when designing new dump trucks, including robotic and unmanned ones.

Algorithm for hydraulic system parameters of a dump truck

“…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.…”

The concept of technogenic risks of a mining transport complex as a tool of lowering the level of its ecological load

“…While estimating the probability of impermissible harmful emissions into the atmosphere, in the first instance, the emission data of a mine dump truck, as the main source of harmful emissions, are to be determined [16], [17]. To a first approximation, the emission data of mine dump trucks TKA can be presented as functional FT with a sum vector of original variables in the following form [17], [18] TKA=FT{XD, XA, XG}, (6) where XD is the original vector of variables, determined by engine parameters; XA is the original vector of variables, determined by the design of a dump truck, in general; XG is the original vector of variables, determined by geometric parameters of mining transport communication lines.…”

“…Original vector XG is determined by geometric parameters of mining transport communication lines (longitudinal gradients, radius of curves, length of tangent level tracks, and etc. ), and it exerts direct influence on the mode of dump truck driving [16], [17], [19], [20]. At a given volume of transportation, the more unstable truck driving becomes, the higher harmful emission is.…”

Justification of the Need to Create Heavy Platforms for Open-Pit Mining

“…Автономная тяжелая платформа будет иметь ключевые отличия [7][8][9][10][11][12][13][14][15], от существующих карьерных самосвалов, в том числе по конструктивному исполнению:…”

“…Рама автономной тяжелой платформы будет рассчитанна на большие нагрузки, а элементы несущей системы, будут иметь отличительные от других карьерных самосвалов, способы крепления к раме. Кроме того, будет применена другая схема расположения колес [9,11], что также будет являться значительным отличием конструкции автомобиля. В конструкции тяжелой платформы будут применяться как унифицированные, так оригинальные изделия, узлы и агрегаты Российского и зарубежного производства (табл.…”
