Mining dump trucks are off-highway dump trucks, which are used to transport coal mines and sand in non-highway field sites, such as large open-pit mines and water conservancy projects. In civil engineering, it is often combined with excavators, loaders, belt conveyors and other construction machinery to form a loading, transporting, and unloading production line to carry out the loading, unloading and transportation of earth, sand, and bulk materials.
Due to the prone to accidents, it is often joked by netizens as the dutiful child making machine.
Off-highway mining dump trucks are mainly composed of engine, chassis, control compartment (front), generator system, body (actuation system) and auxiliary power system.
The characteristics of off-road mining dump trucks are: large tonnage, low consumption, high technical content, and expensive.
According to the transmission mode: Off-highway mining dump trucks can be divided into electric-wheeled off-road mining dump trucks and mechanical drive off-road mining dump trucks. Electric-wheeled off-highway mining dump trucks generally have light-duty tonnage under 108 tonnage, and heavy-duty mine dump trucks generally have a tonnage of 108-360 tonnage; mechanically driven off-road mining dump trucks are generally under 85 tonnage and heavy-duty dump trucks in general at 85-318 tonnage. In the 1970s, due to the lack of large hydraulic torque converters, mining dump trucks above 100 tons were completely dominated by electric drives. With the maturity of large hydraulic torque converters, Caterpillar of the United States has launched a 360-ton hydraulic drive mine dump truck. In the mid-1990s, the AC-AC direct electric drive technology began to be applied to 300-ton mine dump trucks.
Off-highway mine dump trucks have become the main means of transportation for the development and production of open-pit mines due to the advantages of good maneuverability, fast turnover speed and large load capacity. At present, only the United States, Japan, Belarus and a few industrial developed countries in China can independently research and develop the series, ranging from 100 tons to 360 tons.
In 2005, the market capacity of the international mining dump truck market was about 1,300, with a total loading capacity of about 2 billion tons. Mining dump trucks are mainly used in coal mines, gold mines, copper mines and iron mines, and users are mainly distributed in Australia and America. Among them, Australia is the world's largest user of mining vehicles. China and Mongolia are becoming the fastest-growing mining dump truck market.
Since the invention of the electric-wheeled mining dump truck in 1963, after more than 30 years of continuous improvement and the adoption of a large number of new technologies, new materials, and new processes, the heavy-duty electric-wheeled mining dump truck has matured as a new type of automobile, and its loading quality has From 77 tons of the first car to the current largest 317.5 tons. Among the transportation equipment for large-scale open-pit mines with an annual mining volume of more than 10 million tons, electric wheel mining dump trucks have occupied 2/3 of the market, and they are responsible for the mining and transportation of 40% of the world's coal and 90% of the iron ore.
In the selection process of open-pit mine dump trucks, the tonnage of the vehicle should be selected to match the supporting loading machinery. For example, the compartment volume of a mining dump truck is generally 3 or 4 times the volume of an electric bucket.
In addition, it is not that the larger the vehicle tonnage, the better. According to Australian professional statistics, 220 to 240 tons of dump trucks for open-pit mines are the best tonnage. Within this range, the unit transportation cost is the lowest. The choice of mining dump truck body is very important. Its cost is only 1/15 of the entire vehicle, but its impact on the use cost of the vehicle is as high as 1/5. The new mining dump truck body is made of bionic structure, streamlined body and high-strength alloy steel. The body weight is reduced by 20%, and energy saving is reduced by 10%. For mine dump trucks that consume 3000 liters of diesel per day, it is quite impressive. And its service life is 2-3 times that of the traditional car body.
