Large mining machines. The largest mining trucks

31.07.2019

The article will focus on the world's largest dump truck - BelAZ-75710, which has a load capacity of 450 tons. The first copy was released in 2013. This car was created by order of the Siberian Business Union holding. For the first time, operation was carried out at the Chernigovets coal mine. Already in 2014, this truck was able to set a Guinness record, becoming the most lifting vehicle in Europe and CIS countries. He was able to test site transport a mass of 500 tons. In order to purchase this car, it is necessary to spend about 10 billion dollars. The largest BelAZ is produced to this day.

Specifications

This car received a diesel electric power plant. Two diesel engines have a power of more than 1700 kW, that is, 2300 Horse power. An electric generator is installed, as well as a motor-wheel. The traction unit of the BelAZ quarry is capable of operating with four motor-wheels and two generators. The power of each is 1700 kW, and the motor-wheels are 1200 kW. The suspension is used hydropneumatic type. The shock absorbers received a diameter of 18 cm. The car has two fuel tanks with a capacity of 2800 liters each. Max speed car 67 km/h. About 1300 liters are consumed per 100 km.

Why was it created

At the first glance at the BelAZ-75710 car, many people have a question: “Why was it created?” Vehicle devices have significant overall indicators, so few people understand why such a huge dump truck is needed. Many assume that for transportation a large number cargo, two trucks with smaller dimensions can be completely used.

This dump truck, as already mentioned above, was created by order. At that time to work on a career in Kemerovo region needed giant car, so in 2013 the first car with this name appeared. What are the dimensions of BelAZ?

Dimensions and uniqueness

Its length is 20 m, width 9 m, height 8 m, and the carrying capacity, as indicated in the passport, was 450 tons. However, during tests that were carried out in 2014, this car was able to drive with a load of more than 50 tons. If you are interested in how much BelAZ weighs, then the weight of the car is about 360 tons, if we talk about the equipped one. Gross weight is about 900 tons. Even with the fact that the car has such gigantic dimensions, it still cannot be called clumsy, since its turning radius is only 45 m. Uniqueness this dump truck that diesel engines are needed here not to turn the gearbox shaft. It should be borne in mind that there is no gearbox in order to move the car. The vehicle is driven by traction motors.

So the largest dump truck in the world is a hybrid one. It is so high that you can safely go under the car and examine its bottom.

Assembly

When creating the BelAZ-75710, no one tried to make this car smaller or more compact, so all the details are located as accurately as possible and installed just fine. For example, the two main motors are transverse. In total, about 5 thousand horsepower is obtained.

The two motors that were installed in the car have a volume of 65 liters each. They are needed so that the generators work without interference and generate current for the electric motor. Diesels are essential for normal operation hydraulic system. Each motor has its own generator. Most of the systems that ensure the operation and functionality of the motors are of an independent type.

Sometimes drivers report that the device can only run on one engine in order to save fuel as much as possible. Accordingly, the second diesel engine starts working if necessary. This information should not be trusted. In principle, this scheme of work is quite probable, even with such dimensions of BelAZ, but it was not implemented at the plant. However, there are plans for such an implementation.

Generators are designed to generate current for electric motors that are inside the wheels. Many professional drivers know that a bunch of such generators and engines is called a traction unit. However, it is not produced by a Belarusian plant, but by Siemens. Each electric motor of the BelAZ car received a power of 1600 horsepower, so the total power is 6520 hp. With. This type of transmission is called electromechanical.

There is also a power control cabinet located on the deck.

Brake system

Brake unit - UVTR type. brake wheels disk type received hydraulic drive. However, you need to understand that such brakes will not be able to keep such a car in one place (considering how much BelAZ weighs), so the manufacturer added another dynamic type brake system. Here, the electric motor is also working and making movement and stopping.

When the brake system works, heat is generated. Accordingly, it must be removed from the car, so the manufacturer added cooling to the brake resistors in the design.

Machine turn

Also, many may not understand how the car turns, having the same front and rear axles. The answer is simple - they are both managed types. There are two cylinders with tie rods, to put it in your own words. Otherwise, the usual management of the traditional type. There is a steering column, which is practically no different from other dump trucks. Hydraulic accumulators are built into the design, but they are more needed simply for safety reasons.

wheels

The wheels of BelAZ show themselves perfectly, responding well to the movement of the steering wheel. The installed tires on this dump truck also deserve praise. They are made by Bridgestone. As a rule, such tires are not chosen for light cars, however, for the most big BelAZ the most it.

Any driver should understand that messing around with such big wheels- a rather dreary and difficult task. Therefore, the manufacturer made sure that in the event of a breakdown of the traction motors, they could be repaired without removing the wheels. Such characteristics are important for those people who will conduct activities related to the use of such a dump truck. The wheels can only be removed with a crane, and this is a rather lengthy task. These parts are great for handling heavy weights. Details about the carrying capacity of BelAZ were written earlier.

Dump truck deck

The car has a second floor - deck. It is located next to the cab where the driver is located. The latter is called the operator in this machine.

When climbing to the second floor, you can see a metal cabinet, which is a control panel. Here are all the electrics and, importantly, its most important part is the transmission. Next to it is a system that provides cooling for the resistors.

Behind the control cabin is the combined part of the hydraulic system, that is, the combination of the steering, braking system and a special tipping type mechanism.

In the middle of the deck there is a container that is hard to miss. The top of the tank is visible. This is how the cooling system works. Unfortunately, the tank cannot be installed on the lower tier, where the rest of the structure is, so it was brought up so high.

Fans and radiators can be seen at the rear of the cab. There are rear-view mirrors, which may seem rather small at first. However, close up, they are the same size as the mirrors of the house in the hallway. We are talking only about the left mirror, since the right one is really small. Doors open against the direction of travel. This is convenient for both the driver and the passenger.

Control

In control, the largest BelAZ is quite standard, but many are confused by the presence of three pedals and a box selector.

First you need to remember that there is no checkpoint here. The selector is necessary in order to set the direction of the car. To the right of it is a special body control. But why the third pedal? She is in charge of the brakes. In the center is the pedal for hydraulic brake, and in order not to use the clutch lever (which was abandoned), another electrodynamic brake pedal was installed.

It is worth recalling that only a person who has not only cargo category C, but also a special BelAZ operator certificate.

It needs to be noted that steering wheel BelAZ has quite ordinary characteristics, its parts and components are also standard and do not differ in any way from the design on other machines. When buying this dump truck, you can see that it does not have headlights. They are not installed at the factory, although the wiring is done. Checking its performance, the structure is immediately removed. This is done because immediately after the delivery of the car to the customer, the car will still have to be disassembled, so there is no point in installing optics. The buttons, which are located to the right of the steering column, are responsible for the transmission, diesel operation, wiper and glass heating. There is also a special control unit that is responsible for the performance of the heating and air conditioning functions.

This car is designed in such a way that the load on each of the wheels is the same. The suspension travel is small, so if the driver sees some kind of obstacle in front of him, it will be necessary to stop and somehow remove it. The dump truck is unlikely to overcome it. It should be noted: in order for such a car to move with the smoothest possible ride, it is necessary to prepare the ground.

As additional features BelAZ should be noted that it has automatic system fire extinguishing; and tire pressure monitoring. There is also a lubrication system, it is automatic. Built-in cargo loading control system. Due to the electrodynamic braking system, you can safely save the resource of the pads. Besides, brake system works almost instantly. When a person switches from full traction to braking mode, the car changes lanes in a second. Due to the fact that there is no classic box gears, you can make a uniform acceleration without switching.

The BelAZ carrying capacity of 400 tons is really impressive. With a mass above, all systems work stably.

Overclocking and resource

With an electromechanical transmission, accelerating on such a car will be quite easy and safe, since it is unlikely that anything can break here. There is no friction of the parts, respectively, wear and tear is almost minimal.

According to customer reviews, you can see that such cars are capable of driving more than 900 thousand km in a quarry. In reality, many drove more than a million. Although in fact, according to the manufacturer, the resource of this machine is calculated in hours, not kilometers. The maximum speed of the largest BelAZ is 64 km/h.

BelAZ-75710

The largest mining dump truck for transporting rock worldwide BelAZ - 75 710 is produced at Belarusian plant. The load capacity of this machine is 450 tons, and full mass almost 810 tons. Dimensions inspire respect and admiration: more than 8 meters high, almost 10 meters wide and almost 21 meters long. The giant is equipped with two diesel engines with a total power of 4600 hp. and has four-wheel drive and a top speed of just over 60 km/h. Of course, one cannot fail to mention the disadvantage that comes logically from the size of the car, and this is the fuel consumption of the dump truck.

Liebherr-T282B

At one time the most big dump truck received a lot of positive feedback at the exhibition. And no wonder, because the carrying capacity is 363 tons. Own weight is 230 tons. The ratio of the total and transported weight is impressive. Comes with two engines. Very comfortable for the driver.

XCMG DE400

Chinese development - the XCMG DE400 dump truck strikes with a width of ten meters, was presented to the experts in 2012. Its length is almost 16 meters, and the height is 7.6 meters, and up to 360 tons of rock can be loaded into it. The maximum speed of the car is 50 km / h, and with such dimensions, this is also impressive. Before the advent of BelAZ - 75710, it was the largest.

Terex 33-19 Titan

The dump truck manufactured in Canada by Terex 33 - 19 Titan also, having entered the market for the first time in the mid-seventies, surpassed all analogues, being the first in the world with a carrying capacity of almost 320 tons. Was only made single copy, and having worked until the early nineties, it was installed as a monument near the highway near Sparwood, a Canadian city.

Liebherr T284

The Liebherr T 284 dump truck today has no equal in height, which is 8.3 meters, the length of the giant is 15.7 meters, but the width is 8.9 meters. The mass with loaded rock reaches 600 tons. The company is also known for producing large truck cranes.

Bucyrus MT6300AC

The American dump truck Bucyrus M T 6300 AC was launched in early 2008 and is equipped with an engine with a rated power of 3750 hp. It has had its name since 2010 and before that it was called Terex Unit Rig MT 63 00 AC.

Caterpillar 7 9 7 F

Dump truck made in USA Caterpillar 7 9 7 F total weight over 620 tons up to today there is a size winner among all American manufacturers. In the background is a large mining excavator. And you can find out about the winners of the competitions held in Russia among ATV and SSV owners by looking at the corresponding site. Video: trophy raids are available for viewing to everyone.

Komatsu 960E

The brainchild of Japanese engineers Komatsu car 960 E is by far the most large dump truck among Komatsu models.
The car is equipped with V figurative engine with a rated power of 3500 hp The length of the car is 15.6 meters, and the height is more than 7 meters, and despite this, the Komatsu 960E is comfortable and easy to drive, because it is equipped with various systems designed for this.

Bel AZ 75 600

Bel AZ 75 600 has the ability to carry up to 320 tons. Its total mass after loading maximum number rocks can be 560 tons. It is almost fifteen meters long, and its engine develops over three and a half thousand horsepower. With all its enormous size and carrying capacity, it can reach speeds of up to 64 km / h.
The size of all these vehicles, their power and the ability to carry hundreds of tons of cargo, impose on them the impossibility of saving on fuel. Its consumption, as already mentioned, is simply huge, but with the impressive size of the tank, it is just enough for a working day.

Each of us knows that no one has come up with anything better than a dump truck for loading, moving and quickly unloading bulk materials and other cargo. And I am glad that the largest mining dump truck in the world was produced not in America and not in Japan, but by the BelAZ plant in Belarus.

General information

The innovative model of the giant left the assembly line in 2013 by order of the Siberian Business Union holding. With a carrying capacity of four hundred and fifty tons, the first-born of the largest mining dump truck is successfully working at a coal deposit in the Kemerovo region, replacing several dozen other models of dump trucks at once.

Due to the fact that Belarusian engineers lovingly approached the creation of the most powerful more cargo, without dropping, in pursuit of dimensions, the level of quality due to compliance with technology, allowed the largest mining dump truck in the world BelAZ-75710 in 2014 to enter the Guinness Book of Records.

This giant was able to move a load of 503.5 tons on test terrain, which threw off the nearest American and European competitors, maximum load capacity which are about 363 tons, far back.

So, in order not to talk about the decline of the economy and the standard of living in Belarus, the country managed to bypass manufacturers around the world by releasing the largest type of special equipment designed to provide dump truck services.

Technical parameters BelAZ-75710

BelAZ-75710 was able to surprise potential consumers and competitors not only with its dimensions, but also with the solution of a number of complex design tasks that allow you to get both visual and practical pleasure, namely:

With an impressive weight of 810 tons, this mining dump truck is capable of accelerating to 64 km/h, which makes it one step ahead of its competitors, especially in quarrying. To give you an idea of what is being said here, here are some comparisons:

BelAZ-75710 weighs more than the world's largest aircraft Airbuc A380.
The 450t payload is equal to about 300 Ford Focuc or a total weight of 37 double-decker buses, well, or the weight of two large and one small whales.

The Internet is replete with photographs of people against the background of the wheels of this giant. Of course, for people who are twice the height, wheels are required special engine that would make them move. Here, for obvious reasons, two such engines are installed, total power 4600 horsepower, which is also a world record. In the world you will not find such a number of “horses” under the “hood” of any type of transport. Naturally, there are also 2 fuel tanks, each with a capacity of 2800 liters.
The all-wheel drive model BelAZ-75710 has two operating modes. This means that the loaded equipment is served by two diesel generators, and empty - one. This feature was developed by engineers for economic purposes, since the only drawback of the huge dump truck is its fuel consumption of 1300 l / 100 km. But with its carrying capacity and cross-country ability, this figure is not so terrible, especially since mining is constantly growing, and at the same time, the need for such large mining trucks is growing.
This special equipment is designed to carry out work increased complexity in deep quarries, feels quite well with temperature conditions from - 50 to + 50 degrees.
High stability without changing the smoothness of the ride and increased maneuverability contribute to overcoming long slopes up to twelve percent (slopes on short sections of roads - up to 18%).

Additional specifications shown in the table:

By issuing such powerful model of heavy-duty mining dump trucks, the manufacturers set themselves the goal of achieving a reduction in the cost of a ton of transported cargo, which they got at the exit from the assembly line. The need for such machines will only grow.

Top 10 biggest mining trucks

The Liebherr T282B was produced in Switzerland and in 2008 held the championship among heavy trucks. The model of this dump truck, with a carrying capacity of 360 tons and a weight of 230 tons, is intended for serial production. It has 2 engines, like the BelAZ-75710, and also has special amenities for the driver. With its large dimensions, the T282B can pick up speed up to 64.4 km/h.

Terex 33-19 Titan was made in Canada in the only option. Back in 1978, he was the world's largest dump truck. With a weight of 235 tons, the unit had a load capacity of 315 tons. The engine was equipped with 16 cylinders and 4 engines, which is still impressive today. On this moment, one of the largest mining trucks has the status of a monument, which stands near Sparwood next to the highway. But I must say that he worked in coal deposits until the 90s.

XCMG DE400 is China's largest mining dump truck, with impressive dimensions, namely: 10 m wide, 16 m long and 7.6 m high. The world learned about this machine in 2012. Accelerating to 50 km / h with such dimensions, this giant of Chinese thought held the lead until the release of BelAZ-75710.

The Liebherr T284 has a nominal height of 8.3 m among the largest mining trucks in the world. The length and width are respectively 15.7 m and 8.9 m. Max weight of loaded vehicles is about 600 tons.

Bucyrus MT6300AC is an American dump truck with a powerful unit of 3750 l / s, which went to consumers in 2008 under the name Terex Unit Rig MT 6300 AC. The name changed in 2010.

Unit Rig MT 5500 - another one american model, called "quarry general". Its carrying capacity is 326 tons. This manufacturer produced a range of 9 models of heavy-duty diesel-electric dump trucks.

The Caterpillar 797F holds the lead in terms of dimensions among all American dump trucks. The weight of equipment with cargo is 620 tons. The engine has 20 cylinders. In a competitive environment, the manufacturer presents 4 body options for this model. Transport companies they know the reliability of this manufacturer's equipment, because the rental of Caterpillar bulldozers is very popular.

Komatsu 960E is a super-heavy Japanese mining machine. Able to transport cargo weighing 327 tons. Manufacturers took seriously the development of this special equipment, as well as its testing, which lasted 3 years in copper and coal deposits. Today it is produced in the US state of Illinois.

BelAZ-75601 is another Belarusian giant, in the back of which 6 wagons of coal, i.e., 360 tons, can be transported. Its dimensions are comparable to a one-story private house. Total weight with cargo - 610 tons. On-board computer greatly facilitates the work of the driver.

Well, and, in fact, our described giant BelAZ-75710, which no one has yet surpassed in terms of carrying capacity and power.

Conclusion

Demand for the largest mining truck, despite significant fuel consumption, is already high, but it will continue to grow due to its technical data, performance, load capacity, resistance to temperature indicators, and, of course, the opportunity to click on the nose of foreign competitors.

As a child, my brother used to say that there are trucks with wheels so big that a person is smaller than the rim, for some reason I remember this. Now I decided to check, and it turned out to be an exaggeration. But nevertheless, the largest mining dump truck is impressive.
