The biggest BelAZ - career "giant"

Humanity's Need for minerals is large. Every day on our planet is produced not only oil or gas. Problem, but at the same time developed industry is mining of coal. Main place of production of this mineral-quarry. That is, the mine is designed to develop open-cut mining. For the extraction in the earth's crust are deep recesses opening to the goal – coal.

The Main problems of the mining industry

Coal Mining – this is not only the development of a career. The other side of the coin is to transport the received material to the processing plants. To build a career in a huge conveyor that discharges coal to the top, not economically feasible, because its design is subject to constant overloads, which will become worthless after a couple months of work. To pave the way for a railway transportation is also very problematic, as access to the maximum depth of the quarry occurs on a spiral trajectory. So the only true solution to the problem of transportation is the largest BelAZ-dump truck made in Belarus.

Why the dump truck?

Why use such a large transport? This is beneficial due to its power and capacity. Just imagine what a conventional tractor of the type “rig” can carry only 20 tons of cargo, while the largest BelAZ 450 tons of moves with no problems. So, after some calculations get such a special vehicle able to replace almost 23 of the truck. If we consider not very comfortable conditions for movement of transport on the spiral way of the quarry, the dump truck of this size is simply irreplaceable.

Benefits of dump trucks

If to continue the theme of the benefits that have dump trucks, other modes of transport, they give odds on the following parameters:

1. The largest BelAZ has good maneuverability that allows to work at relatively close venues, and in places of education, hard faces.
2. Low cost of construction and maintenance of temporary road in his career. If the normal movement of the truck tractor will need a good road surface (at least the gravel road, carefully leveled with a bulldozer), the biggest BelAZ is able to climb a hill with a constant slope of 12% and temporary – 18%. The result is a quarry can be more compact.
3. Permeability of dump trucks is much superior to conventional heavy vehicles. This is achieved due to the huge size of the wheels and the elaborate design of the drive. So, the biggest BelAZ has a record wheel, which diameter is about 4 meters.
4. In conjunction with shovels dump truck to enable maximum performance of field development.

Road transport has one significant disadvantage when compared with train – the high cost of fuel. However, in view of the above-described circumstances, it is possible to close eyes. Therefore, the dump truck is indispensable in the transportation of ore rocks for short distances with the subsequent loading on the train.

Lineup

The Relevance of the design stimulates car manufacturers to develop a wide range of dump trucks. The release of such “giants” are engaged in many engineering enterprises worldwide. One of them was organized in September, 1948 the Byelorussian SSR. Left pictures, which are the biggest Trucks of that time working for the good of the Soviet socialist society on major mining companies.

Today, the plant has significantly expanded model range. Classify the vehicles at the payload:

1. 30 tons – 7540А, 7540С, 7540В.
2. 45 tons – 77547, 75473.
3. 55 tons – 7555В, 7555Е.
4. 90 tons-7557.
5. 110-136 tonnes – 75137, 75135.
6. 154-160 tonnes – 7517.
7. 200-220 tons – 75302, 75306.
8. 320 tons – 7560.

The Leader, who became the pride of the developers is the largest dump truck BelAZ 7571 capacity of 450 tons.

Case studies products

During the activities of the plant in the Belarusian city of Zhodino has significantly expanded its customer base, so that today boasts every third mining dump truck in the world with their logo on the back. With regard to the above-described record, the biggest BelAZ is successfully operating in the Kemerovo region of Russia. The dimensions of the dump truck is really amazing: length-20,6 m; width – of 9.87 meters; height – more than 8 meters. Fuel consumption at maximum load for both power plants is nearly 600 liters per hour.

There are other regions of the world where trucks from Belarus help to extract minerals. For example, in January of this year started operation of BelAZ with carrying capacity of 110 tons at the Tavan Tolgoi located in the Gobi desert (Mongolia).
