There are several models of giant dump trucks used in heavy industry for quarrying in the world. All of these supercars are unique in their class. Therefore, it is not surprising that every year a kind of competition is held between the producing countries: whose dump trucks are the most load-bearing, fast and enduring. A separate line indicates the question "in which country the largest dump truck in the world is produced." Technological progress can no longer be stopped. Car performance has reached fantastic heights. At the same time, production technologies continue to improve. Therefore, the largest dump truck in the world may appear unexpectedly, as it happened more than once. The parameters, characteristics and dimensions of new models are regularly calculated by competent specialists in research centers. The analytical work of engineering services is international.

Mining Giants

The largest dump truck in the world, BelAZ-75710, miningthe unparalleled giant was unveiled at the test site on September 25, 2013. The machine is produced at the factories of OJSC "BelAZ", located in the city of Zhodino, not far from Minsk. The technical characteristics of the dump truck are impressive, it takes on board 450 tons of cargo, while its European and American counterparts lift only 380 tons. The giant weighs 810 tons, but at the same time it is able to reach speeds of up to 64 km / h. And although such speeds in career developments do not make sense, however, the very fact of such dynamics testifies to the unprecedented power of the car. The new machine was awarded the title of "The Biggest Dump Truck in the World 2013". Over the past year, not a single career car appeared in the world ranking, which could outstrip BelAZ-75710 in terms of its characteristics. Therefore, with every right, the Belarusian giant can bear the title of "The Biggest Dump Truck in the World in 2014". The release of the mining giant has begun, the first machines are already working in the largest mines around the world.

In working mode, the largest dump truck in the world usually moves through the mining area at a speed of 10-12 km / h. Maintenance of the machine consists in the periodic inspection of the power plant and chassis. Mechanics operate on the principle "it is easier to prevent a breakdown than to fix it later." Repair of a mining dump truck is possible only at specialized enterprises equipped with lifting mechanisms like port cranes. And from the quarry to the place of repair, the car has to be delivered on several tractors. TechnicalManufacturers try to locate service centers in the zone of greatest accessibility to a quarry or a mine where dump trucks operate. Otherwise, the issue of delivering the car to the place of repair and back can result in a large sum. Therefore, there are special intermediary firms that are engaged in optimizing the location of service centers. In addition, practice shows that the owners of large industrial developments in the field of extraction of raw materials and minerals purchase mining equipment from the same manufacturer. This allows you to work for years according to a well-established scheme with the least losses. Maintenance of the material part is usually carried out by the manufacturer's specialists, who arrive at the site according to a certain schedule.

Fuel consumption - 500 liters per hour. Is it a lot or a little?

The largest dump truck in the world has, accordingly, a heavy-duty power plant, which consists of two diesel generators that produce a total thrust of 8500 hp. with., and supplies energy to four electric drives that ensure the rotation of the wheels. Electric motors drive the wheels of the dump truck when the body is fully loaded with maximum traction. And an empty car moves in the mode of 50% power cut, for this one of the diesel generators is turned off. Diesel fuel consumption in full mode is about 500 liters per hour. As we can see, the largest dump truck consumes a huge amount of fuel. However, the cost of diesel fuel is nothing compared to the economic benefit, which is expressedseven digits. And it is precisely thanks to the mining giants-dump trucks.

Camcorders and other useful devices

The equipment of the BelAZ-75710 mining dump truck includes sophisticated but effective fire extinguishing systems and viewing "dead" zones around the car. To do this, eight permanently operating video cameras are installed along the perimeter of the machine, transmitting information to monitors in the driver's cab. The driver-operator and navigator are accommodated in a double spacious cabin. In addition to the video review, the dump truck is equipped with a special device that warns of approaching high-voltage lines. The cabin has air conditioning in summer and a heater in winter. The largest dump truck in the world BelAZ-75710 is a supercar designed to work in difficult conditions at temperatures from minus 50 to plus 50 degrees. The resource of the machine allows it to operate around the clock.

History of Appearance

The development and production of the BelAZ-75710 dump truck was caused by an increase in the demand for heavy-duty vehicles for the mining industry. Existing machines could no longer cope with the volumes of transported raw materials. In recent years, there has been a worldwide trend towards an increase in the production of giant dump trucks. Moreover, their number is not limited by any specific norms, the need for career carriers is so great. The more such machines will be produced, the better for the world economy. Taking into account the needs, demand on the market and its capabilities, the Belarusian company plans to enter the production of 1,000 dump trucks per year. And this is only a plan for the production of cars of the latest generation. In addition to the new BelAZ-75710, the production of previous models that are not yet obsolete will continue.

The predecessor of the 75710 model is the BelAZ-75601, which successfully operates in hundreds of open pit mines around the world. Features the following:

• Length - 14 m 900 cm.
• Height - 7220 mm.
• Width - 9250 mm.
• The weight of the dump truck without loading is 250,000 kg.
• Capacity - 360 tons.
• GVW - 610 tons.
• Engine - power 3807 hp s., 2800 kW.
• Fuel consumption - 500liters per hour.
• Tubeless tires - 59/80 R63, radial, quarry tread, damage resistant.

Prospects

Factory capacities of BelAZ are constantly expanding, only in the last three years several new workshops with a total area of more than 30 thousand square meters have been built. 700 high-tech machines have been installed, modern production methods are being introduced. Today, BelAZ holds the world championship in terms of the variety of vehicles produced, its model range includes about twenty modifications of mining dump trucks. Simultaneously with the increase in output, the quality of the machines is increasing. The resource of the Belarusian giants has more than doubled, currently it is 1 million kilometers - before it was 400 thousand.

Export

Quarry equipment that rolled off the factory assembly line in Zhodzina is shipped all over the world. Mining enterprises in different countries willingly take Belarusian-made dump trucks: reliable, trouble-free and fully provided with quality maintenance. There are practically no complaints - they can cost too much. Therefore, the production of mining equipment is strictly controlled at all stages of production. In addition, the developers are trying not to complicate the design of the machine, in order to avoid breakdowns. Each manufacturer is familiar with the proverb "where it's thin, it breaks there", so everything is done thoroughly, with a multiple margin of safety.

Global competitors

Bthe category "The largest dump trucks in the world" at different times included other representatives of such vehicles. For example, the Japanese mining giant Komatsu 930E-3SE, which is the main achievement of this country in the production of heavy equipment for the mining industry. The characteristics of the Komatsu 930E dump truck are impressive. The machine is equipped with an 18-cylinder turbodiesel engine with a capacity of 3500 hp. With. The torque of the motor is unprecedentedly high, it is 1900 rpm. The length of the giant is 15.5 meters, while the car is capable of carrying 290 tons of cargo. When fully loaded, the dump truck weighs about 800 tons.

The car carries 340 liters of engine oil in the crankcase, and 720 liters of antifreeze is poured into the cooling system. The scheme for transferring energy to the wheels of a Japanese dump truck is common for such machines: the engine transmits rotation to an alternator that feeds electric motors.

Caterpillar

Another mining truck from the list of "The Biggest Dump Trucks in the World" is the American-made Caterpillar 797B, which radically differs from its "brothers" in a number of parameters and technical characteristics. There are no wheel electric drives in its design, on the chassis there is a huge diesel engine with a working volume of 117 liters, which transmits rotation through a seven-speed automatic transmission to the rear wheels. Half of the driver's work is shifted to a computerthe central unit that successfully controls several dozen parameters, aligning the indicators of the main components and assemblies of the dump truck.

The "American" has a complex brake system, which is fundamentally different from the devices of other career giants. Most supercars operating in mining open-pits have an electrodynamic brake principle, while the Caterpillar has a hydraulic one, that is, in fact, an ordinary automobile. To improve efficiency, the area of the brake discs has been increased to 32 square meters in total. For example: this is almost three times more compared to the disks of the Japanese dump truck Komatsu 930. The pads of the American car are cooled by several oil coolers.

Liebherr T282B

The main competitor of the BelAZ-75710 is the Liebherr T282B mining truck, which is also on the "Largest dump trucks" list. Supercar Liebherr T282B was named "the eighth wonder of the world" in 2004 at the premiere in Germany. At that time, the new machine made a splash with an unprecedented ratio of its own weight and the volume of cargo that a dump truck could carry. According to this indicator, the car came out on top and held an honorable position until the appearance of BelAZ-75710 in 2013. The world ranking called "The Biggest Dump Trucks" is regularly updated. However, machines have not yet been created that could outrun the BelAZ-75710 and Liebherr T282B. But, since progress does not stand still, we should expect new ones to appear in the near future.masterpieces of engineering in the field of career development.

So, it has already been determined that the largest dump truck after the Belarusian giant is a German competitor. The Liebherr T282B power plant is a classic combination of mining dump truck parameters: diesel generator - converter - electric motor. A 20-cylinder diesel engine paired with an alternator is located above the front wheels, traction motors are mounted in the rear axle. Combined brakes. Resistor energy dampers are installed on each wheel. To help these brakes, there are two discs on the rear wheels and one on the front. All disc brake actuators are hydraulic.

Unreachable BelAZ-75710

The largest dump truck in the world, the photo of which is presented on the page, is still an orange giant that rolled off the assembly line in the Belarusian city of Zhodino. The BelAZ engineering staff is currently preparing a number of improvements that will further strengthen the already high rating of the 75710 model. Thus, the largest dump truck in the world, with a carrying capacity of more than 450 tons, will become unattainable in the coming years for competing manufacturers.

Production of quarry equipment is very expensive. Therefore, there are no new large manufacturers in the world. But there are many contractors who are able to produce high-quality components and assemblies for machines operating in the mining industry. itmotor builders, super tire companies and other specialized enterprises available for cooperation. Career automotive equipment is expensive, the price of a high-class dump truck reaches five to six million dollars. However, the machine justifies the cost in the first two years, while bringing a significant profit.

Giant mining dump trucks never stand idle, in most cases this technique works around the clock. The management of the mining section should only prepare the drivers on time, and BelAZ, Caterpiller and Komatsu will do the rest.
