Due to the rapid development of mining in the coming years, the demand for lifting and large dump trucks is growing relentlessly. Among the giant dump trucks, there are record holders.

Large and hoisting dump trucks

In recent years, the demand for large machines with enormous payloads has grown steadily. It's about dump trucks. Several countries specialize in their production. Let us consider in more detail the characteristics of dump trucks with the highest carrying capacity.

Liebherr T 282B

In 2008, the first place in terms of carrying capacity was awarded to a mining dump truck manufactured in Switzerland. It was recognized as the largest in the world. This model is not an experimental model, it is a production car. Its carrying capacity is three hundred and sixty-three tons, and its total weight is five hundred ninety-two tons.

The T 282 B is capable of accelerating to sixty-four kilometers four hundred meters per hour. The length of the dump truck is fourteen and a half meters, with a height of seven meters and forty centimeters and a width of nearly nine meters.

Terex titan

The American company GM in 1978 in a single copy was released a huge truck. At that time, it was the largest in the world, but even today its size is surprising. With a carrying capacity of three hundred and fifteen tons, it weighs two hundred and thirty-five tons. The truck is equipped with a sixteen cylinder engine and four motors.

Today Terex Titan is located in Canada in the city of Sparwood and serves as a monument exhibit. It was used in coal mines until 1990. After the need for this giant was gone, they wanted to cut it, but it was decided to turn the truck into an exhibit. It is not on the move as the engine has been disassembled into parts.

Caterpillar797F

The largest in the Caterpillar range is the 797F. Its carrying capacity is four hundred tons. The American manufacturer has managed to combine all the advantages of its predecessors in this line in this model.

The giant machine is equipped with a twenty-cylinder engine. The manufacturer offers four body types for this model.

BelAZ 75601

The huge dump truck of the Belarusian plant is equal in height to a one-story house, its carrying capacity is three hundred and sixty tons. The back of this super-car can easily fit six coal cars. The model is called BelAZ 75601, the car is equipped with an on-board computer.

The total mass of the dump truck is six hundred and ten tons. Its height is without ten centimeters fifteen meters, and its width is nine meters twenty-five centimeters.

Komatsu 960E

Another super-heavy dump truck was developed in Japan. It's about Komatsu 960E. The height of this car is seven meters, and the diameter of the tires is four meters. Its purpose is the mining industry. The maximum carrying capacity of the giant dump truck is three hundred twenty seven tons.

The model was developed by Komastu America Corp. The dump truck is produced in the USA in the state of Illinois. The tests lasted three years in the most difficult conditions of copper and coal mines.

Unit Rig MT 5500

In America, a giant dump truck was produced, the carrying capacity of which was three hundred twenty-six tons. It's about Unit Rig MT 5500. Its second name is general of quarries. A fairly young corporation Terex, specializing in the production of such giants, is considered one of the largest.

Unit Rig has nine large dump truck models, but only the MT 5500 has such a high payload capacity. The entire range is diesel-electric dump trucks.

Belaz is the largest dump truck in the world

Among all dump trucks in the world, the largest was created by the company "BelAZ". Its name is BelAZ-75710. This "giant" has a carrying capacity of four hundred and fifty tons. For comparison, the following examples can be given: the carrying capacity of this dump truck is comparable to the weight of three hundred Ford Focus vehicles, the weight of two and a half whales and the weight of thirty-seven double-decker buses. Even the world's largest passenger aircraft, the Airbus A380, weighs less than the BelAZ-75710.

The record-breaking dump truck was presented for the first time at a test site near Minsk in the city of Zhodino in September 2010 and was declared the largest in the world. Prior to that, leading positions were behind the BelAZ-75601 dump truck, which appeared in 2007, and the Liebherr T282B produced in Switzerland, which was introduced in 2003.

BelAZ-75710 was in the Guinness Book of Records for a total weight of eight hundred and ten tons. The car is equipped with two diesel engines. The maximum speed of the record dump truck is sixty-four kilometers per hour.

The mining dump truck was made for performing extremely complex work in open pit mines, as well as for work in deep quarries. The machine is capable of operating at minus fifty and plus fifty degrees Celsius.

The presentation of the new giant-record holder was timed to coincide with the sixty-fifth anniversary of the BelAZ plant. The demand for this dump truck is high, which is in line with the general global trend of increased demand for heavy mining heavy-duty dump trucks.

And the largest passenger plane in the world can carry 555 passengers. ...

They have no place in the city. They have no place on the track. They have no place at all on the roads. Because they have not yet created such roads along which mining dump trucks could easily move. Thousands of horsepower, tens of thousands of Newton-meters of torque, hundreds of tons of dead weight - the permanent habitat of all this magnificence of mines and opencast mining. And, despite the fact that the automotive industry is very specific and limited, and the cost of each dump truck is several million dollars, the competition is very high. But unlike conventional cars, where the struggle is for comfort, dynamic characteristics and design, here the best ones are determined by other parameters, the most important of which is carrying capacity. So, some representatives of heavy equipment at one time are able to transport more than 350 tons of rock in their body! And even more, they do it every day, without interruption for weekends and holidays. And the car rests only in case of breakdown, planned maintenance or on the way to a new place of work.

The giants go to the place of work disassembled - asphalt roads, which without consequences could withstand their weight, have not yet been invented. Is it cruel? Yes, cruel, but it cannot be otherwise. After the purchase, the car must immediately work off the considerable costs for its purchase, and every minute of downtime is very expensive for the owner. So huge giants work almost round the clock, crawling along the paths of mines and developments. If you look at this picture from the window of a helicopter or from the observation deck, then everything seems quite organic: narrow paths and ordinary trucks. You begin to realize the scale of what is happening only if you find yourself in close proximity.

And then the small paths turn into wide plateaus, on which giants as high as a good two-story house and almost ten meters wide are quietly driving away, carrying in bodies along a small Everest. And from the height of human growth, which, by the way, is half the height of the wheel of a mining dump truck, it is not necessary to think that “that whopper is a little smaller than that one”. And yet they differ. So, for example, the Japanese Komatsu 930E-3SE in the improvised four of the largest auto monsters can be put in fourth place.

4th place. Komatsu 930E-3SE.

The Komatsu 930E-3SE is the flagship of the Japanese heavy equipment manufacturer, with a gross vehicle weight of 504 tons and an engine power of 3500 horsepower. The car is a little less than 15.5 meters long and is capable of carrying up to 290 tons of cargo in its "womb". And its total mass is neither more nor less than 500 tons! In order to move such a whopper from its place under the hood (in the figurative sense of the word) there is an 18-cylinder turbodiesel engine with a capacity of 3500 horsepower, which it develops at 1900 rpm. By the way, this power unit boasts not only high power and killer torque, but also a considerable weight - 10 tons! And this figure does not seem entirely fantastic, especially after you find out that 340 liters of engine oil "splashes" in his wet sump lubrication system, and all 719 liters of antifreeze in the cooling system. Unlike conventional cars, where the engine flywheel is connected to the drive wheels through a gearbox, a different traction unit scheme is the most popular in mining dump trucks. The engine does not give all its power to the mechanical transmission, but to the alternator, which in turn powers the traction motors.

The dimensions of the truck are really huge - in its body it can transport a medium-sized country house. By the way, electric motors are part of the rear axle, which means that they are working samples of the notorious motor-wheels, which we will never see in the passenger sector. The torque from the electric motors is transmitted to the giant wheels with a tire landing diameter of 63 inches not directly, but through compact gearboxes (so the volume of oil required for the operation of each gearbox is only 95 (!) Liters of the "transmission"). With such a power unit, the maximum speed of the Komatsu 930E-3SE is 64.5 kilometers per hour, which is not enough for such a colossus, and the problem here is not how to accelerate it, but how to stop it. A hybrid braking system is working on this task, which consists of three subsystems: main, auxiliary and parking. The main system is hydraulic, multi-disc, with separate circuits of the front and rear axles and oil-cooled brake discs. The maximum brake fluid pressure in the circuit is 172 atmospheres and at the same time, during braking, the total friction surface is almost 10 square meters! But even such a system cannot cope with a giant alone, so an auxiliary - an electrodynamic braking system - works to help it. During braking, the traction motors are switched to generator mode, and all the electricity they generate is converted into heat at the load resistors. The power dissipated by the resistors can peak at over 4000 kilowatts! While the average value of this parameter is 2900 kilowatts. The parking brake system - with dry brake discs, is able to hold a fully loaded vehicle on a 15% incline. Cylinder drive - mechanical spring, control - hydraulic.

3rd place. BelAZ 75600.

Almost the domestic BelAZ 75600 consumes more than 500 liters of diesel fuel per hour of operation. Even more ore than the Komatsu 930E-3SE can be transported by the BelAZ 75600, a truck that is in stock in the elite class of 300-ton mining dump trucks. Its maximum carrying capacity is 320 tons, and the gross weight of the loaded vehicle is 560 tons. Moreover, its length is even less than that of the Japanese heavyweight - only 14.9 meters. As a power unit at BelAZ, an 18-cylinder V-shaped Cummins QSK78-C turbodiesel with a volume of 77.6 liters is used. The rated engine power is 3546 horsepower, the torque is 13771 Nm. The scheme of the power plant is combined with an alternator and two traction electric motors from Siemens, with a capacity of 1200 kilowatts each. The maximum speed of the vehicle is 64 km / h. By the way, the average fuel consumption per hour for such a colossus fluctuates around 500-550 liters of diesel fuel per hour, so a standard 4375-liter tank will be enough just for a work shift.

The BelAZ 75600 uses a combined hydraulic system, which includes a platform tipping mechanism, braking system and steering. The whole thing is driven by a variable displacement axial piston two-section pump. The total volume of the hydraulic system is 600 liters of oil, the pressure in the working circuit is 165 atmospheres. Steering at BelAZ with an emergency circuit - in case of failure of the main system or engine shutdown, pneumatic accumulators come into operation, the energy supply of which is enough to make a couple of maneuvers. The suspension is fully dependent, 2 oil shock absorbers with gas pressure are installed in front, one at the rear. The shock absorbers are distinguished by ultra-small piston strokes: 200 mm for the front axle and 170 mm for the rear axle. By the way, in terms of forming a list of additional options, mining dump trucks are no different from passenger cars, of course, adjusted for specifics. So for BelAZ 75600, you can additionally order an air conditioner, an additional heater, a tire pressure monitoring system and even heated rear-view mirrors! In addition, a dump truck can be equipped with very specific options, which is one warning system about approaching high-voltage lines or a vehicle load control system.

2nd place. Caterpillar 797B.

The Caterpillar 797B is by design a regular truck, if not very large. The second place was taken by a representative of the most famous manufacturer of heavy equipment - Caterpillar 797B. A giant with a gross weight of almost 624 tons, is able to take on board 345 tonscargo. Moreover, it has a design that is quite exotic for mining dump trucks. Although, if you look from a conventional automotive point of view, the Caterpillar 797B is built according to traditional, even more classic canons: a rear-wheel drive car with front steer wheels, a turbodiesel engine and a hydromechanical transmission.

The power unit of the Caterpillar 797B is amazing: 24 cylinders, 117 liters of displacement, 3550 horsepower and 16,000 Nm of torque! In front of the dump truck is a huge 24-cylinder engine with a working volume of 117 liters! In order to create such a motor, the engineers actually had to take two 12-cylinder Cat 3512B engines and combine them together. Despite the large volume, the engine power is only 4 horsepower more than that of BelAZ. The manufacturer promises to compensate for such "stinginess" by the increased resource of the engine, and for this purpose the maximum revolutions were limited. But the torque here is really record: more than 16,000 Nm! From the engine, the torque is transmitted through a short propeller shaft to the largest gearbox in the world! The hydromechanical planetary gearbox has 7 stages and is computer controlled.

In general, the Caterpillar 797B is rightfully considered one of the most electronics-packed mining dump trucks. The central unit controls hundreds of parameters and, depending on external conditions, adjusts the operation of the engine, transmission and braking system. So, during the start of a loaded dump truck or climbing uphill, the system briefly increases the torque by 22% of the nominal value and selects the optimal moments for gear shifting, and during braking it does not allow the wheels to lock and the vehicle to be pulled off the trajectory.

The love of Americans for "automatic" and positive displacement motors made itself felt in heavy equipment - Caterpillar 797B boasts the largest transmission and the largest engine. What I really had to work hard on was the braking system. If from competitors, the main part of the work is taken over by the electrodynamic brakes, then here the entire load falls on the hydraulics. To ensure stopping a fully loaded car, the total working area of \u200b\u200bthe brake discs had to be increased to 33 square meters - more than three times more than that of the same Komatsu. In addition, the brakes have a powerful oil cooling system and a backup circuit with a hydraulic lock - as soon as the pressure in the circuit drops, the brake cylinders stop the car under the action of a spring.

Two pedals, a steering wheel, an automatic selector - the driver's workplace is quite ordinary. By the way, Caterpillar 797B boasts several records: the largest engine - 117 liters of working volume and 24 cylinders; the largest transmission, the largest top speed - almost 68 km / h; the most capacious fuel tank - 6800 liters. But still, it prevents him from taking first place ...

1st place. Liebherr-T282B.

The eighth wonder of the world. This is what the Liebherr-T282B was nicknamed during the premiere at a construction exhibition in Germany. 363 tons... No truck in the world can take on more cargo than Liebherr-T282B yet. At the same time, its curb weight is 50 tons less than that of the Caterpillar 797B - 230 tons versus 280 for the American. It is in the ability to carry as much cargo as possible with the lowest unladen weight that design perfection is assessed, and in this parameter the Liebherr-T282B surpasses all its competitors. The car can be equipped with two engines: either an 18-cylinder Cummins QSK 78 (as in the BelAZ 75600) weighing 11,300 kilograms, or a lighter and more powerful "twenty" Detroit Diesel, with a volume of 90 liters, with a capacity of 3650 l / s. The scheme of the power plant is classic for mining dump trucks - the engine drives the alternator, and the traction power is Siemens electric motors.

The 20-cylinder engine with an alternator is located above the front wheels, the traction motors instead of the rear axle. The brakes are hybrid. The main work is taken over by the electrodynamic braking system, turning traction electric motors into generators, which in turn extinguish the generated energy on special resistors. They are assisted by hydraulic disc brakes: one brake disc on the front wheels and a pair on the rear. Unlike other dump trucks, where one hydraulic system serves, steering, brakes and a body tipping system, here the first two systems are equipped with their own independent 1060 liter circuit with a backup hydraulic accumulator.

In addition to technical data, an image from video cameras located along the perimeter of the body can be displayed on the liquid crystal dashboard. Driving such a colossus is not easy at all, and a driver's mistake can be really expensive, so everything is done in the car to make it easier for the driver to work. In the cab, well protected from external noise and dust, the pedals and steering wheel are in their usual places, and in front of the driver's eyes is a progressive LCD dashboard. The driver is saved from the heat by an air conditioner with a powerful air filtration system, an equally powerful stove from the cold, and a modern audio system from boredom, and the realization that the largest car in the world is in control of your hands.

Humanity has been mining minerals in various forms for thousands of years. It would seem that these days the process must be automated at all, so that robots can perform work operations. Nevertheless, due to the specifics of the technology for extracting minerals in remote deposits, heavy transport is still relevant, impressive in its size and functionality. Therefore, quarry machines are not just a utilitarian tool of narrow specialization, but also, in some way, a work of engineering art. The largest machine-building giants are working on the development of the characteristics of this technology, as a result of which real champions in terms of size and weight are published at different intervals.

Major manufacturers of quarry equipment

Not every vehicle manufacturer can afford to work in the segment of large trucks with dump truck capabilities. This requires not only high production capacity, but also research and development engineering potential, which can take decades to develop. The leading positions on the regular basis are Belarusian machines - open-pit "BelAZ", which are also distinguished by high carrying capacity, weight and the presence of technologically advanced controls.

German off-road dump trucks Liebherr and American Caterpillar products are in direct competition with them. 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, Euclid, Volvo and Japan's Komatsu produce dump truck models with successful combinations of power and performance.

BelAZ-75710

The model was released in 2013 and is positioned as a dump truck of the highest carrying capacity category. Without exaggeration, this is the largest career 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, an absolute record was set at the test site - 503.5 tons.Considering that the machine itself weighs 360 tons, the load on the power plant and structure was 863 t.

Obviously, not every engine can handle this 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 capacity of two diesel units is 2330 liters. from. As for the dimensions, the BelAZ quarry 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 supplied with shock absorbers with a diameter of 170 mm, wheels of 63/50 size and tires of the 59 / 80R63 format. The fuel tank has a capacity of 2800 liters, and the truck has two containers.

Liebherr T282B

A fairly old model, released back in 2004, but even by today's standards, against the background of the characteristics of other quarry equipment, it looks worthy. The carrying capacity of the German dump truck is 363 tons. Compared to BelAZ's offer, the indicator is not high, but this gap is applicable to other representatives of the segment as well. With its own weight of 252 tons, the machine is capable of serving a maximum operating weight of 600 tons.

The dump truck has the following overall parameters: 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 terms of carrying capacity. Nonetheless, Liebherr's mining machines stand out for their modern technology. 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 operator of the T282B interacts with the equipment through an ergonomic and functional display.

Caterpillar 797

Also far from a new development already from American designers, and this once again confirms that large-scale 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 are improved. The basic version 797, released in 2002, was replaced by the 797B, with a capacity potential of 345 tons, which is 18 tons more than the first generation.

In 2009, Caterpillar launched an even more powerful machine, the 797F mining truck, which can lift 363 tonnes, like its German competitor T282B. Against the background of the expansion of lifting capabilities, the capacity potential also increased. For example, the 24-cylinder diesel unit provides 3370 hp. from. An important difference between the 797F and previous models is the speed limit of 68 km / h. The gap from other cars of this group is small, but even 3-4 km / h can be important in this area of \u200b\u200bapplication of transport equipment.

Terex 33-19

The product of Canadian specialists, which, perhaps, has the richest biography of all the trucks presented in the review. The model rolled off the assembly line in 1974 and it is not surprising that at its time it was for a long time the largest and most lifting machine. With a mass of 235 tons, the design and power units of the Terex 33-19 provided lifting of 350 tons, which is still a high indicator today.

Also, in terms of size, the Canadian dump truck does not lag behind the modern record holder from Belarus. The length of the quarry vehicle is also 20 m and the height is 7 meters. Moreover, with the unloading compartment raised, the height will reach 17 m. But, of course, the technological backwardness of those times also could not but leave its mark. A diesel plant with a group of electric motors with a working volume of about 170 liters was able to provide a maximum speed of 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 lifting machines and Japanese machine builders. Komatsu is famous for its small-sized forklift trucks, forklift trucks and various carts. But the example of a full-fledged quarry vehicle, the photo of which is shown above, confirms the manufacturer's success in the development of large trucks. The model can handle a mass of about 290 tons, and the full operating load can be 500 tons. The power potential of the machine is 3014 liters. from. with an engine volume of 4542 liters.

The advantages of the 930 E-3 SE include a high degree of reliability, build quality and durability of the element base. However, the imprisonment of Japanese specialists for small-format forklifts nevertheless made itself felt. The weak point of the truck was precisely the massiveness of the hull, which is poorly controlled and does not allow complex maneuvers.

XCMG DE400

It is also an interesting development, distinguished by high technical and operational indicators and a decent carrying capacity. By the way, the last parameter is 350 tons. It can be said that this is a standard and unremarkable indicator, but in comparison with many of the above-mentioned representatives of the segment, it is achieved with a lower power resource - 2596 hp. from. with a total volume of the engine cylinders of 3633 liters.

As for the design, we can talk about the opposite qualities with respect to the Japanese car discussed above. The XCMG quarry equipment has approximately the same dimensions, but does not restrict movement. The cross-country ability of this version of the dump truck is its main advantage, allowing it to work in coal, hard stone and sand deposits. Reliability during movement is facilitated by modern balancing of the elements of the supporting base, as well as a computerized trajectory control system with the ability to lock the wheels.

Euclid EH5000

Another car originally from Japan. The Euclid brand is little known to a wide audience, but it is overseen by one of the world's largest manufacturers of machinery and equipment Hitachi. In the EH series of the manufacturer there are 12 models, the most powerful of which, the EH5000, is capable of lifting about 320 tons. The geometric volume of the equipment is 197 m 3, and the power potential is 2013 kW. The features of this truck include the 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). Has its own characteristics and proprietary suspension Euclid with Neocon shock absorbers. This combination operates on the principle of the compression of the working fluid, which increases both the reliability and productivity of the equipment - suffice it to say that the operation of the undercarriage due to this solution increases by 20-25%.

BelAZ 75600

It is worth noting again the advantages of the Belarusian car industry, but this time on the example of the younger version of the dump truck. This modification easily serves 320 tons with a maximum load of 560 tons. The length of the machine is 15 m, which is 5 m less than the same indicator 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. from.

In other words, this is a standard dump truck from the 300-ton line. It is not the largest, but one of the most productive mining machines in the world in its segment. The photo below shows the original diagram of the motors, which are also collected 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, providing a speed of up to 64 km / h.

Dump trucks "Volvo"

The Swedish manufacturer does not claim to be a leader in this list, but its products deserve attention due to the many original technological solutions used 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 features dump trucks with Tier 4 Final engines, providing a maximum lifting capacity 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 indicators are seriously inferior to the capabilities of the considered giants, but low technical and operational characteristics are compensated for 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-format trucks operating on asphalt roads. But it is the dump trucks that demonstrate the highest carrying capacity and overall dimensions. At least in this category, record holders appear more often. To date, the largest quarry vehicle is represented by the BelAZ enterprise. It is a massive 20 m, capable of practically lifting 500 tons. It is noteworthy that no competitor is even close to this performance. The main group of high-performance dump trucks focuses on servicing a mass of 300-400 tons. At the same time, as experts note, the ceiling of 500 tons will become irrelevant in the near future, since it will be pressed even more with a carrying capacity of 600 tons or more.

The development of industry is impossible without such a giant special equipment, therefore it is very popular in the field of construction and the creation of various quarries for the extraction of, for example, sand or coal. The manufacturers of these dump trucks are increasing their capacity, adding reliability and productivity to them. It should be noted the TOP 5 largest mining dump trucks (and mining excavators) in the world. And even the owners of giant dump trucks need to know about cargo evacuation.
