BelAZ 75710 is a unique dump truck with a payload capacity of 450 tons, considered the largest in the world. The car debuted in the fall of 2013. The first model in December 2014 went to the Kemerovo region to the city of Berezovsky for operation in the Chernigovets coal mine. A month later, the equipment transported a load weighing 503.5 tons across the training ground, setting a record officially recorded in the Guinness Book.
The second copy of BelAZ 75710 was assembled in 2016. For several years, the car has been tested on the territory of the Belarusian Automobile Plant. The third car is at the assembly stage. All models are intended for operation in Russia.
The predecessor of the BelAZ 75710 was the super-heavy BelAZ 75501 vehicle, capable of transporting up to 280 tons. Until 2005, the model was considered the flagship of the Belarusian Automobile Plant line. However, the appearance of the BelAZ 75600 with a payload capacity of 320 tons disrupted its hegemony. The developers did not stop there and created an even more powerful version - BelAZ 75710.
The main reason for the development of such a large dump truck was not the desire for fame and records, but economic benefit. Compared to vehicles with a smaller carrying capacity, one copy of the BelAZ 75710 provides significant benefits. Despite the high cost and serious maintenance costs, the model has the lowest cost of transporting 1 ton of rock among all mining dump trucks.
BelAZ 75710 is the largest dump truck in the world.
There are a large number of amazing inventions in the world. Many of them are so unusual or huge that it is difficult to believe in their existence.
Giant mining dump trucks from BelAZ are a clear confirmation of this. For several decades, the Belarusian holding has been producing huge vehicles for transporting goods for various purposes.
BelAZ 75710 belongs to the category of dump trucks, but is not considered a full-fledged truck. This is due to the fact that it cannot be used on public roads.
BelAZ 75710, released in 2012, is considered the largest dump truck on the planet . A dump truck refers to a giant machine that is used preferably in quarries. Previously, we described the no less interesting 45-ton EDumper, released by the Swiss company eMining AG. It also belongs to this class of trucks, but is inferior in weight.
The Swiss dump truck is capable of transporting up to 60 tons of cargo. At the same time, the BelAZ trailer can easily accommodate 7.5 times more . According to official data, none of the top five dump truck manufacturers have brought something similar to the market.
To understand how impressive the BelAZ 75710 is, it's better to look at the numbers. Many of them are simply unimaginable. We at 1Gai.Ru have collected facts for you about the world's largest Belarusian dump truck.
How much does it cost to ship a dump truck?
Please note that the price also includes the following:
- Delivery of special equipment. The huge car weighs more than 360 tons, so it is transported in parts on 22 railway platforms. Moreover, they must withstand loads weighing up to 41 tons.
- BelAZ assembly on site. To install all components, a construction crane with a large lifting capacity is required. The height of the BelAZ is at least 8 m with a width of 10 m. Therefore, it is not possible to assemble it manually.

The drive system on this monster is much larger than that of a Swiss electric dump truck. The main working unit in this car is a diesel power unit, consisting of two V16 engines with a volume of 65 liters each. In this case, each engine is started separately. Together they generate 4660 hp. With. power with a thrust of 18,626 Nm. It is extremely difficult to believe such figures, since they are comparable to the parameters of the 12 engines of the fastest car in the world, the Bugatti Veyron.
The cooling complex for such engines has a volume of 1380 liters , but that’s not all. The power of the fan responsible for blowing the radiator is 128 KM. Identical parameters are present in the power plant of the compact urban hatchback.
The system is subject to special efficiency requirements, since the car is designed to operate in a wide temperature range - from -50 to +50 degrees Celsius.
8 filters installed at the front (they resemble lights) are responsible for the cleanliness of the air that enters the engines.
The capacity of the lubricant reservoir is 550 liters . This volume would be enough to change the oil in a regular passenger car 100 times (about 1,000,000 km). It is interesting that BelAZ has an outstanding operational resource. It easily covers 100,000 km annually, working in quarry conditions.
Engine
BelAZ 75710 is equipped with 2 MTU Detroit Diesel 16V4000 diesel units mounted transversely. The engine compartment of a car is huge and compactness is out of the question.
Characteristics of MTU Detroit Diesel 16V4000 power plants (1 engine):
- working volume – 65 l;
- rated power – 1715 (2330) kW (hp);
- maximum torque – 9313 Nm;

In fact, Belaz is a hybrid
BelAZ
Two diesel engines are only part of the drive system, since in practice the dump truck has a hybrid drive. The car has generators with a capacity of up to 3500 kW, which generate electricity for electric motors . In total, BelAZ has 4 generators of 1600 liters each. With. The total is 6400 liters. pp., distributed between 4 wheels (eight wheels (four gable).
The dump truck is designed to perform a large number of tasks because it has dual wheels and each tire weighs 5.8 tons. A total of 46.4 tons of weight. Tire size - 59/8-R63. They can hold up to 7 atmospheres of air.
BELAZ-7558
Mining dump trucks of the BelAZ-7558 series are designed for transporting rock mass in a loosened state along technological roads in open-pit mining operations with different climatic conditions. They can be used in the construction of large industrial and hydraulic structures, in the construction of highway complexes, as well as in technological departments of processing industry enterprises.
Development of the world's first 90-tonne mining dump trucks with electromechanical transmission began in 2010. In mid-2012, the first prototype was produced. In 2013, a modification of the BelAZ-75581 was assembled, at the beginning of 2015, the BelAZ-75583, and in 2017, the BelAZ-75585.
The dump truck has a classic layout for the Belarusian automaker: an abundance of straight lines and angles, practical forms of body panels, as well as a massive, but only slightly protruding hood, along the edges of which there are stairs for climbing to the upper platform. On the site with a fenced perimeter, a cabin is mounted on the left, and electrical equipment cabinets are located on the right. From above, the platform is completely covered by a protruding body visor.
The machine's cabin is equipped with front inclined glazing, has two side doors and an ergonomic interior. The driver's seat is mounted on air springs and has a wide range of position adjustments. The cabin also has an additional seat for a passenger, an adjustable steering column, a cabin heater and air conditioning.
The standard body on the BelAZ-7558 is a welded metal body with a triangular side profile. The body is equipped with a bottom heating system, a locking device in the raised position and a FOPS standard safety complex. In addition, the design of the dump truck provides for the replacement of the standard body with a coal platform with extended side walls. The lifting of the body is ensured by a set of telescopic hydraulic cylinders with three working stages (one double-acting), into which the working fluid is supplied through an axial piston variable-displacement oil pump, which also supplies the brake and steering circuits.
All motors are combined with an electromechanical transmission, which includes a traction generator, a pair of traction electric motors, two motor-wheel gearboxes with a gear ratio of 30.36 and a set of equipment for monitoring and regulating operating modes.
The BelAZ-7558 is based on a durable two-axle chassis with a frame welded from box-section spars and variable height. The spars are made of low-alloy steel and reinforced with cross members.
A dependent pneumatic-hydraulic suspension with integrated hydraulic shock absorbers and transverse rods is mounted on both axles of the dump truck.
The steering of the dump truck is hydraulic volumetric, with drive to the wheels of the front axle.
To ensure greater driving safety, the BelAZ-7558 is equipped with four independent braking systems: main (dry single-disc mechanisms on all wheels), parking (permanently closed brakes on the rear wheels with spring drive and hydraulic control), auxiliary (electrodynamic brake on traction electric motors) and a spare (serviceable circuits of the main and parking brake systems).
The list of standard equipment of the BelAZ-7558 includes a combined fire extinguishing system, a centralized lubrication system, a tire pressure monitoring system, a pre-heater, an alarm device for approaching the explosive line, a video surveillance system, stone ejectors and stone chippers. As optional equipment, the dump truck can be equipped with: electrically heated side mirrors, a heated fuel filter, an additional heater and bottom lining.
The popularity of BelAZ-7558 series dump trucks is constantly growing. Since entering serial production, the company has produced more than 200 mining dump trucks. Today, new 90-ton machines with the BELAZ brand are successfully operating at mining enterprises in Russia, Uzbekistan, Vietnam, Kazakhstan, South Africa and Mongolia.
