Work in quarries associated with the extraction and movement of large volumes of hard rock - the heaviest and most difficult to handle cargo, in conditions of monstrous dust, heat and cold, can only be maintained by the most enduring and powerful technique. We present to your attention several stories of the creation and operation of giant mining machines that have become real champions in their industry.
Bagger 288
Mining dump trucks BelAZ-75710 and Volvo A60H
The most recognizable symbol of any quarry is a colossal dump truck. These machines are designed to transport the extracted rock. This technique is mainly used to move hard rocks. In 2013, the world saw a new industry record holder - the BelAZ-75710 car manufactured by the Belarusian Automobile Plant. The declared carrying capacity of the car is 450 tons, which roughly corresponds to the transportation capabilities of seven freight cars at the same time.
BelAZ-75710
The weight of the heavy truck is 360 tons when empty. It is capable of reaching speeds of 64 kilometers per hour. The car was equipped with two MTU engines total power 4.651 thousand horsepower. The dimensions of the giant in length, width and height are 20, 9.7 and 8 meters, respectively. The machine was included in the European and CIS Book of Records after it set a load capacity record. At the test site, where demonstration tests took place, she carried 503.5 tons of cargo. Recall that Pronedra wrote earlier that the machines of the future are mining dump trucks-robots.

In addition to classic-shaped dump trucks, to which the mentioned BelAZ belongs, articulated trucks are also used in quarries. The first copies of this kind appeared in the fifties. They are used in cases where there are increased requirements for maneuverability or maneuverability in specific areas. Such trucks are equipped with six driving wheels. The leader among cars is the Volvo A60H, introduced to the market in 2016. Its carrying capacity - 60 tons - although it has a much more modest figure than that of a conventional "quarry", it still leads against the background of the capabilities of other dump trucks in its class.

Bucket wheel excavator Bagger 288
In order to open the layers of minerals in quarries, powerful equipment is required that can extract a large number of breeds. For this, rotary excavators are used in large developments. Such machines are mechanisms of continuous operation on a walking, rail or tracked chassis. The extraction of raw materials is carried out using buckets or cutters mounted on a rotor wheel. The extracted material is transported on a conveyor to intermediate collection points or shipped to transport.
Bagger 288
The largest bucket wheel excavator is Bagger 288. It was built in 1978 German company Krupp commissioned by Rheinbraun. The unit also has the status of the largest self-propelled machine in the world. However, due to the fact that the Bagger 288 runs on electricity that comes from external sources, it is more correct to call it a movable apparatus. The weight of the giant is 13.5 thousand tons, in length, width and height it reaches 240, 96 and 46 meters, respectively. The car moves on 12 tracks, while the maximum speed is 600 meters per hour.
The volume of each of the 18 buckets mounted on a rotary wheel the size of an eight-story house is 6.6 cubic meters. During a work shift, an excavator extracts 240 thousand cubic meters of rock, which is comparable to the amount of space in a football stadium. However, a whole family of bucket-wheel excavators of the Bagger series, created in the period from 1958 to 1995 - models 281, 285, 287 and 291, has comparable dimensions and characteristics. In addition, the Bagger 293 excavator is included in the Guinness Book of Records for certain parameters.

Draglines Big Muskie and Bucyrus 8750
At work on the opening of the rock, excavators with a cable mechanical connection, the so-called draglines, are used, the principle of operation of which is based on the use own weight bucket. There are among these machines and their champions. The 4250-W, which even had its own name - Big Muskie, was considered the largest career dragline. The excavator was built in 1969 by the American company Bucyrus Erie for coal mining operations at the Central Ohio Coal open pit in Ohio.
Big Muskie
The mass of the machine was 13 thousand tons, height - 67.8 meters, width - 46.2 meters and length - 148.6 meters (together with the boom). Inside the building, two buildings the size of the American White House could easily fit on top of each other. The bucket with a volume of 168 cubic meters included two full-size buses. The 4250-W worked on electricity, power was supplied through a cable from external sources. The cable itself had to be transported after the excavator using a separate machine. The power consumed by Big Muskie is comparable to the amount of energy that is needed to ensure the operation of electrical appliances in 27.5 thousand apartments.
The life of the excavator was 30 years. During this time, the machine moved 465 million cubic meters of rock - twice as much as during the construction of the Panama Canal. With the help of the record holder, 20 million tons of coal were extracted. After dismantling the giant, his bucket was placed in the Miners Memorial Park of Ohio.
Big Muskie bucket at Miners Memorial Park
After the dismantling of the legendary Big Muskie, the status of the largest dragline in the world passed to American model Bucyrus 8750 manufactured by Bucyrus Erie (in 1997 the company was bought out by by Caterpillar Corporation, which is why the machine is currently called the Cat 8750). The model was introduced to the market in 1971 and is still in use today. Even though the Bucyrus 8750 is half the weight of the Big Muskie, its performance is on par with the latter.
Cat 8750 (Bucyrus 8750)
A machine weighing up to 7.5 thousand tons holds 116 cubic meters of cargo in the bucket with a mass of not more than 344 tons. Thus, the excavator can fully load a mining truck in one go. The length of the arrow reaches 132 meters. The excavator is equipped with 16 electric motors, half of which are used during the operation of the bucket, the rest drive the chassis.
Mechanized excavator Marion 6360 Captain
In quarry work, in addition to rotary machines and draglines, other excavation equipment is also used - powerful mechanical shovels, which are used to open rocks. Meshlopats are familiar to us single bucket excavators, which work on urban construction sites, their principle of operation is not based on the use of the weight of the bucket, but mainly on the transfer of traction through mechanical devices.
Marion 6360 Captain
The category record holder is the Marion 6360 Captain, created by the American company Marion Power Shovel in 1965. The excavator worked from 1965 to 1991 in the Captain Mine (Illinois) coal mine, which is operated by Arch Coal. With a weight of 12.7 thousand tons and a height of 64 meters, it had an arrow length of 72 meters and a bucket volume of 153 cubic meters. Only one segment of the caterpillar track weighed 3.5 tons, and the height of the tracks was 4.9 meters. The operation of the machine was provided by two dozen electric motors with a total capacity of 15.45 thousand kW each.
The excavator successfully coped with its tasks until the emergency, which occurred on September 9, 1991. There was a fire in the car. After examining the excavator, the engineers came to the conclusion that it was not economically feasible to restore the Marion 6360 Captain. The gigantic mechanism was dismantled a year after it stood motionless at the lower level of the quarry.
Front loader P&H L-2350
For moving and cutting rock, bulldozing and loading raw materials onto dump trucks in quarries, front loaders. They are earth-moving machines with a mounted bucket, which is unloaded forward. The American company R. G. LeTourneau in 2000 managed to create the most efficient loader in the world - L-2350 loader (new name P&H L-2350). The capacity of its bucket is 40.52 cubic meters, which allows it to carry a record 72.5 tons of cargo. Loader weight - 263 tons.
P&H L-2350
A diesel engine with a capacity of 2.3 thousand horsepower consumes fuel from a giant fuel tank with a capacity of 4 thousand liters. Movement speed this transport small - 15 kilometers per hour. The wheels of a colossus deserve special attention- in height they reach four meters, and in width - 1.7 meters. This machine involved in the Arizona copper quarry, which is being developed by ASARCO. The assembly of the loader was carried out directly in the quarry. The machine will spend its entire service life in it and will no longer be transported to other workings.
Bulldozers Komatsu D575A and ACCO
In the extraction of minerals in quarries, bulldozers are also used. It is intended for different types works - both for moving rocks and for leveling the soil. In particular, the rock can be transported to the coverage area of an excavator, which loads it onto a dump truck or dump. Bulldozers are widely used in overburden work.
Komatsu D575A
by the most big bulldozer in the world of those used in quarries is the Komatsu D575A Superdozer. Its production by Japanese company Komatsu started in 1991. The mass of the machine reaches 152.6 tons. The colossus is able to carry out the movement of 69.3 cubic meters of rock, and when changing the blade to a special one - 90 cubic meters. The bulldozer is transported disassembled and using up to eight tractors. Now such bulldozers, although out of production, are actively used in New Zealand and the USA.
However, another practically implemented ACCO dozer project could also become a record holder among bulldozers, but this machine was never involved in the work. Its weight far exceeds the record holder Komatsu and reaches 183 tons. The bulldozer was assembled Italian company Umberto Acco based on Caterpillar in the sixties commissioned by Libya.
ACCO doser
After the introduction of UN sanctions, the delivery failed, and today the giant is still in Italy. Although it has not been sea tested, in 2012, while transporting the ACCO dozer to the address of the new Italian owner, a landscaping company, according to eyewitnesses, the bulldozer drove into the trailer site on its own. The purpose of the bulldozer is unknown, but still it can be considered a career one, since such super-heavy class machines are used throughout the world exclusively in open-pit mining.
Transport and dump bridge Tenova TAKRAF F60
Among all types of moving equipment involved in work in quarries, the largest in size are the structures of transport and dump bridges. These devices are used to transport overburden from bucket-wheel excavators to internal quarry dumps. The rock is transferred to a maximum of three ledges of development.
Tenova TAKRAF F60
The F60 manufactured by the German corporation Tenova TAKRAF is considered the largest transport and dump bridge. He works in coal mines in the eastern part of Germany. The car was built in 1991. The bridge weighing 13.4 thousand tons moves along rail guides. The length of the structure is 502 meters, width - 202 meters, span height - 60 meters. For comparison, Manhattan's 101-story Empire State Building is 443 meters high, 62 meters less than the F60.
Operating speed - at the level of 9 meters per second (32.4 kilometers per hour), maximum - 15 meters per second (54 kilometers per hour). The volume of production is 29 thousand cubic meters per hour (the rock in such an amount can fill the bowl of a football stadium to a height of three meters), if three rotary excavator. Rock is transported using nine conveyor belts.

Quarry colossi, designed for hard multi-year work, are often assembled and dismantled for scrap after the expiration of their service life or an accident right on the field sites. Starting and ending life in the same career is not an easy fate. huge machines which are often created in single copy, and, after the termination of their existence, forever remain in history as unique examples of engineering talent.
Mining trucks are powerful productive machines that are used during open pit mining. Almost all trucks of this type are equipped with an electric transmission and braking system. Currently, there are quite a few different mining trucks in the world, but today let's look at the largest of them.
BelAZ-75710
BelAZ-75710 is the world's largest dump truck, which is capable of carrying 450 tons (before that, the largest truck in the world was considered to be a truck with a carrying capacity of 360 tons). The first model of a mining truck was released in 2013.

Bucyrus MT6300AC
The American two-axle mining dump truck Bucyrus M T 6300 AC was designed and manufactured in 2007. Until 2010, this machine was called Terex Unit Rig MT 63 00 AC. 
The car was equipped with a 20-liter turbocharged engine with a capacity of 3750 hp. The volume of the fuel tank was equal to 4971 liters. The overall length of the Bucyrus MT6300AC dump truck is 15570 mm, width - 9700 mm, height - 7920 mm. The curb weight of the truck is 240300 kg, carrying capacity is 363 tons. The maximum speed is 64 km/h.
Caterpillar 797 F
The Caterpillar 797 F is a US-made mining truck with a total weight of over 620 tons and a rated payload of 400 tons. 
The heart of this giant is diesel engine Cat C175-20 ACERT, 4000 HP (2983 kW), which is a single 20-cylinder block.
Komatsu 960E
Today, the Komatsu 960E mining dump truck is the largest among other models of the Japanese company Komatsu. 
The car is equipped with V figurative engine, whose power is 3500 hp. The car is 15.6 meters long and over 7 meters high.
Komatsu 930E-3SE
The gross weight of the Japanese truck Komatsu 930E-3SE is 504 tons. The dump truck, whose length is about 15 meters, is capable of carrying up to 290 tons of cargo. 
Under the hood of the Komatsu 930E-3SE is an 18-cylinder turbodiesel engine 3500 hp at 1900 rpm.
BelAZ 75600
Its maximum load capacity is 320 tons, and the gross vehicle weight is 560 tons. The length of BelAZ 75600 is only 14.9 meters. The heart of this mining truck is an 18-cylinder V-shaped Cummins QSK78-C turbodiesel with a volume of 77.6 liters (3546 hp and 13771 Nm of torque). The maximum speed of the car is 64 km/h, the average fuel consumption is 500-550 liters per hour.
Humanity has been mining in various forms for thousands of years. It would seem that today the process should be automated at all, so that robots perform work operations. Nevertheless, due to the specifics of the technology of mining minerals at remote deposits, heavy transport, which impresses with its size and functionality, still remains relevant. Therefore, mining machines are not just a utilitarian tool of narrow specialization, but also in some way a work of engineering art. The largest engineering giants are working on the development of the characteristics of this technology, as a result of which, at different intervals, real champions in terms of size and weight are released.
The main manufacturers of mining equipment
Not every manufacturer of vehicles as such can afford to work in the segment of large trucks with the capabilities of a dump truck. This requires not only high production capacity, but also a research and engineering capability that may take decades to develop. Belarusian vehicles regularly take leadership positions - mining BelAZ trucks, which are also distinguished by their high carrying capacity, weight and the presence of technological controls.
They are directly competed with German off-road dump trucks Liebherr and American products Caterpillar. The Terex concern is also actively strengthening its position, in the family of which a whole scattering of high-performance trucks has appeared in recent years. From time to time, dump truck models that are successful in terms of power and performance characteristics are produced by Euclid, Volvo and the Japanese Komatsu.
BelAZ-75710
The model was released in 2013 and is positioned as a dump truck of the highest load capacity category. Without exaggeration, this is the largest mining machine in the world. The photo above shows its impressive size. According to the manufacturer and official documentation, this version is capable of lifting 450 tons. However, in 2014, on test site an absolute record was set - 503.5 tons. Taking into account the fact that the machine itself weighs 360 tons, the load on the power plant and structure was 863 tons.
Obviously, not every engine can cope with such a weight, even by the standards of the dump truck segment. The developers used a diesel-electric power complex, which involves several functional blocks. For example, the power potential of two diesel units is 2330 liters. With. As for the dimensions, the BelAZ mining machine of this version has a length of 20 m, a height of more than 8 m and a width of about 10 m. The machine is equipped with shock absorbers with a diameter of 170 mm, wheels of size 63/50 and tires format 59 / 80R63. The capacity of the fuel tank is 2800 liters, and the truck has two tanks.
Liebherr T282B
Enough old model, released back in 2004, but by today's standards, against the background of the characteristics of another mining equipment looks decent. The carrying capacity of the German dump truck is 363 tons. Compared to the offer of BelAZ, the figure is not high, but this gap is applicable to other representatives of the segment. With a dead weight of 252 tons, the machine is capable of handling a maximum operating weight of 600 tons.
The overall parameters of the dump truck are as follows: length 15.3 m, height about 8 m and width - 9.5 m. That is, the Belarusian competitor has a significant advantage both in size and in load capacity. Nevertheless, Liebherr mining machines compare favorably with the presence modern technologies. So, if the traditional mechanics of controlling the working bodies of a truck involves the use of a dashboard in combination with levers, then the T282B operator interacts with the equipment through an ergonomic and functional display.
Caterpillar 797
Also far from new development already from American designers, and this once again confirms that large mining equipment with increased technical and physical parameters appears infrequently. However, the example of this truck shows the dynamics of the development of the model as the modifications improve. The basic version 797, released in 2002, was replaced by the 797B, the power potential of which was 345 tons, which is 18 tons more than the first generation.
In 2009, Caterpillar released an even more productive machine, the 797F Mining Truck, which can lift 363 tons, just like German competitor T282B. Against the background of expanding lifting capabilities, the power potential also increased. For example, 24-cylinder diesel unit provides 3370 hp With. An important difference between the 797F version and previous models is the speed limit of 68 km/h. The gap from other machines in this group is small, but even 3-4 km / h can make a difference in this area of application of transport technology.
Terex 33-19
The product of Canadian specialists, which, perhaps, has the richest biography of all the trucks presented in the review. The model left the assembly line in 1974 and it is not surprising that at one time it was the largest and most lifting machine for a long time. With a mass of 235 tons, the design and power units Terex 33-19 provided a lift of 350 tons, which is still a high figure today.
Also, in terms of size, the Canadian dump truck does not lag behind the modern champion from Belarus. The length of the mining machine is also 20 m, and the height is 7 meters. Moreover, with a raised unloading compartment, the height will reach 17 m. But, of course, the technological backwardness of those times also could not but leave its mark. Diesel plant with a group of electric motors with a working volume of about 170 l was able to provide top speed no more than 50 km / h, which is a very weak indicator these days.
Komatsu 930 E-3 SE
Do not lag behind the fashion for large hoisting machines and Japanese machine builders. Komatsu is famous for its compact loaders - stackers, fork technology and various trucks. But the example of a full-fledged quarry vehicle, the photo of which is shown above, also confirms the manufacturer's success in developing large trucks. The model copes with a mass of about 290 tons, and the full operational load can be 500 tons. The power potential of the machine is 3014 liters. With. with an engine capacity of 4542 liters.
The advantages of the 930 E-3 SE include a high degree of reliability, build quality and durability of the structural element base. However, the sharpness of Japanese specialists for small-format forklifts nevertheless made itself felt. Weak point the truck was precisely the massiveness of the hull, which is poorly controlled and does not allow complex maneuvers.
XCMG DE400
Also an interesting development, characterized by high technical and operational performance and a decent load capacity. By the way, the last parameter is 350 tons. We can say that this is a standard and unremarkable indicator, but compared to many of the above representatives of the segment, it is achieved with a smaller power resource - 2596 liters. With. with a total volume of engine cylinders of 3633 liters.
As for the design, we can talk about the opposite qualities with respect to the above Japanese car. The XCMG quarry equipment has approximately the same dimensions, but does not limit the possibility of movement. The cross-country ability of this version of the dump truck is its main advantage, allowing it to work on coal, hard stone and sand deposits. Reliability during movement is facilitated by modern balancing of the elements of the carrier base, as well as a computer trajectory control system with the ability to lock the wheels.
Euclid EH5000
Another car comes from Japan. The Euclid brand is little known to a wide audience, but it is overseen by Hitachi, one of the world's largest manufacturers of machinery and equipment. The manufacturer's EH series includes 12 models, the most powerful of which, EH5000, is capable of lifting about 320 tons. The geometric volume of equipment is 197 m 3, and power potential- 2013 kW. The features of this truck should also include increased structural strength.
The walls of the body of large mining machines of the EH family are made on the basis of wear-resistant steel Hardox 400. The thickness of the body elements varies from 8 (visor) to 26 mm (bottom). It has its own characteristics and proprietary Euclid suspension with Neocon shock absorbers. This combination functions on the principle of compressing the working fluid medium, which increases both the reliability and productivity of the equipment - suffice it to say that the operation of the undercarriage is increased by 20-25% thanks to this solution.
BelAZ 75600
It is worth reiterating the benefits Belarusian automobile industry, but already on the example of the younger version of the dump truck. This modification easily serves 320 tons at maximum load 560 tons. The length of the machine is 15 m, which is 5 m less than that of the record holder in the class. As for the power plant, it is formed by a V-shaped 18-cylinder turbodiesel with 78 hp. Power output is 3546 liters. With.
In other words, this standard dump truck from the 300-ton range. This is not the largest, but in its segment one of the most productive mining machines in the world. The photo below shows the original circuit of the engines, which, among other things, are assembled from Siemens electrical installations with a power of 1.2 kW. Thanks to this installation, the equipment is capable, on the one hand, of delivering torque at the level of 13771 Nm, and on the other hand, of providing speeds of up to 64 km/h.
Volvo dump trucks
The Swedish manufacturer does not claim to leadership positions in this list, but its products deserve attention due to the many original technological solutions used specifically in trucks. We are talking about series with indices G and H. The first was formed in 2014, and the second company promises in the near future.
As for the G-family, it includes dump trucks with Tier 4 Final engines that provide a maximum payload of 35-40 tons. The H series is expected to be the most productive Volvo mining machine of the A60H modification. Its carrying capacity should be at least 60 tons. As you can see, these figures are seriously inferior to the capabilities of the considered giants, but low technical and operational characteristics are compensated by maneuverability, proprietary telematics systems and advanced functional support.
Conclusion
The general segment of mining equipment is not at all the most advanced in terms of high technical parameters. There are also all kinds of tractors, industrial transporters and conventional large trucks operating on asphalt roads. But it is dump trucks that demonstrate maximum load capacity And overall indicators. At least in this category, champions appear more often. To date, the largest mining machine is represented by the BelAZ enterprise. This is a massive 20 m, capable of practically lifting 500 tons. It is noteworthy that even close to this operating characteristic no competitor is worth it. The main group of high-capacity dump trucks is focused on servicing a mass of 300-400 tons. At the same time, according to experts, the 500-ton ceiling will become irrelevant in the near future, as it will be pushed even more with a carrying capacity of 600 tons or more.
Without these giants, the development of industry is not possible, the requirements of customers for such special equipment are constantly growing. Manufacturers are consistently increasing capacity, reliability and performance. Consider the popular, 10 models of the largest dump trucks in the world.
Komatsu 930 E-3 S E
This successful model Komatsu's largest mining dump truck from Japanese manufacturers. The principle position of the company: "to work next to technology." On the base Yaroslavl plant created by Komatsu Manufacturing Rus LLC, many elements of the 930 E-3 S E are supplied for assembly directly from Japan, some are made by us. It is beneficial for Russian customers to work with Komatsu manufacturers, they have moved most of the production to Russia, and have established excellent service.
BelAZ 75 600
The machine of Belarusian manufacturers occupies a worthy place in the market of the largest dump trucks in the world. One of the improvements on this model is the body structure. Now the bodies are supplied from the Kuzbass Carriage Building Company. They are made of strong, durable Hardox-450 steel with the addition of alloying elements. This is one of the largest trucks produced in the post-Soviet territory.
Terex Unit Rig MT 5500
One of the largest trucks in the world of British manufacturers. There are many useful innovations in the design of the car. Consumers appreciate this model for a well-calculated frame design that endures loads with minimal stress. This will allow manufacturers to give a guarantee for 40 thousand hours of operation. Steering based on a continuous bridge design, which reduces the number of moving parts. The tire alignment on the bridge beam does not change, resulting in reduced rubber wear.
Komatsu 960E
Impressive photo of the largest dump truck in the world of Japanese manufacturers, Komatsu, which closely cooperates with Russian consumers. IN Kemerovo region, where more than 400 of the largest Japanese trucks in the world of Komatsu, a service for the maintenance and repair of Japanese equipment has been established. Despite its impressive size and weight, it is clearly visible in the video that Komatsu's largest dump truck is easily controlled. This is achieved by the design features of the bridges and a powerful steering hydraulic system.
BelAZ-75601
The model is one of latest developments plant of the largest BelAZ dump trucks. The video of the largest dump trucks in the world shows that the BelAZ-75601 was created on the basis of the BelAZ-75600. The differences in the photo are almost invisible, they are in individual elements, which are taken from other manufacturers of the largest trucks in the world. MTU 20V4000 engine, 3.75 thousand hp, electric drive transmission, elements of Siemens electronic diagnostics. Cab with improved visibility, LCD monitor on the control panel.
Titan 33-19
The uniqueness of the once largest dump truck in the world shown in the photo is that it was produced by Terex in a single copy. After 13 years of productive work in the quarries of California and other fields, he was scrapped. But in 1993, wise men restored the most big truck and now, as a historical landmark, it is displayed under Sparwood. Tourists are happy to take a photo of the largest mining dump truck in the world in the 70s of the last century.
Liebherr T 282B
The Swiss model of one of the largest dump trucks in the world turned out to be successful, with sales of 75 units per year. Buyers appreciated the diesel-electric transmission joint production Siemens and Liebherr. The carrying capacity of one of the largest dump trucks in the world is 363 tons. The reliability of the brakes has been increased, they are electronically controlled, keeping the colossus on a slope of 15%.
MT6300AC
This model of one of the largest dump trucks in the world includes modern achievements of special equipment of this class. The load capacity of the dump truck is 363 tons, while the chassis is on two axles, so less rubber is required. AC electric transmission. Since 2008, Bucyrus has merged with Liebherr and the Bucyrus line of the largest dump trucks has become known as the UnitRig.
BelAZ-75710
The new model of BelAZ manufacturers became a finalist of the Swedish Steel Prize 2014 and was awarded the title of "the largest dump truck in the world." Competitors of world manufacturers of mining equipment appreciated its advantages: a swivel body and bridges, high-strength body steel. BelAZ 75710 is the largest dump truck in the world, operates at -60 °C, and in conditions of lack of oxygen at an altitude of 5 thousand meters above sea level.
Conclusion
The listed properties of the 10 largest mining trucks in the world show that global manufacturers offer consumers equipment with ample opportunities. Every year, the productivity of dump trucks, labor safety on them, and comfortable conditions for work.
Many would probably agree that commercial transport, or rather, cargo, and in particular mining trucks, are the key "driving force" in the process of formation, development and operation of the mining and processing industries all over the world. From their effective work, which is a direct dependence on their possible transported volume and mass, there is also a “general picture” of their expediency and application.
So, to put it simply, in this article we wanted to talk about the largest mining dump truck in the world, which no one and nothing can replace in its business. Under the very big dump trucks(cars), we, first of all, mean the most lifting vehicles.
The largest dump truck (load-lifting) in the world
So this article will be about BelAZ 75710. The car began to be produced in 2013 at the Belarusian Automobile Plant, from where the abbreviation BelAZ comes from.

In the same year of production of BelAZ 75710, the plant applied for inclusion in the Guinness Book of Records and for good reason. You will understand that this is a rather ambitious dump truck from our further description. So, since 2013, it has been the largest (load-lifting) mass-produced mining dump truck.

Thus, the BelAZ-75710 mining dump truck is capable of carrying up to 450 tons of cargo. For example, an ordinary cargo Railway carriage, for example, for the transportation of coal, transports about 50 tons. That is, BelAZ 75710 is capable of taking away about 9 wagons with coal at a time, which, perhaps, can be equated to a small shunting train at the station, which forms the main trains. It is worth noting that BelAZ transports cargo not on rails, but sometimes on complete off-road. At the same time, the speed can reach 64 km / h, but this is no longer in a loaded state.

The total mass of the BelAZ 75710 dump truck (loaded) is also impressive, as is its carrying capacity, as its total weight is 810 tons.
Of the features of the largest dump truck, it is worth noting the Siemens electromechanical transmission, which helps to operate the gear shift on the machine. It is also necessary to say about the engine, with a power of 4600 hp, that the car has 4 twin wheels, that is, in total 8, four-wheel drive for every couple.

The machine has the following overall dimensions:
Height: 8.16 m
Width: 9.87 m
Length: 20.60 m
The fuel consumption of a car does not tend to be small, like itself. So, of course, everything will depend on the operating modes of the dump truck, but in quarry conditions, the predicted fuel consumption will be about a ton per 100 km of run.
The largest dump truck is equipped with radial tubeless, pneumatic Michelin tires. The dump truck has a ROPS safety system, which is designed to control and prevent a possible rollover of the machine. At the same time, the dump truck meets all international standards for emissions, noise, and the requirement for a workplace in the cab.
In general, we can say that the largest dump truck is the embodiment of high technology, complex calculations, considerable experience and great diligence of the workers of the Belarusian Automobile Plant. It is also impossible to ignore the fact that the plant is located in the neighboring country of Russia - Belarus and has a rich history dating back to the USSR. Also in Soviet time BelAZ was one of the main dump trucks used for mining in the USSR. It is pleasant to realize that even today, in the realities of the modern world market, the plant is able to produce competitive, demanded and unique products on the world market.
