dump truck - a type of special self-unloading equipment designed to transport goods in an iron body mounted on a car chassis. The main design is a tilting body, but there is a rare option where the body is rigidly fixed to the frame, and the mechanism tilts the entire machine.
Tilt body can be mounted on the chassis truck, semi-trailer, trailer. The main purpose of the dump truck is the transportation of bulk, bulk and other similar goods that do not require containers, which can be loaded directly into the body, and unloaded by tipping the body.
Dump trucks are classified:
1. by body type:
Platform;
- sliding platform;
- bunker.
2. by unloading:
- forced unloading (for example, auger) or slope;
- using telescopic lifts.
3. in the direction of unloading:
Back or sideways;
Universal or double sided.
4. according to the place of application:
Mining dump trucks;
- road dump trucks;
- dump trucks for underground work.
5. by design type:
- biaxial;
Triaxial;
- multiaxial;
- dump truck with articulated frame.
6. by load capacity
Small - up to 2 tons,
Medium - 2-10 tons,
Heavy 10-30 tons,
Super heavy - from 30 tons and more;
7. by type of rolling stock
Truck – dump truck (one vehicle without a trailer),
Road train-dump truck (tipper truck together with a dump trailer, or a truck with a semi-trailer dump truck);
8. according to the possibilities of operation on various types roads
- the dump truck can only move on paved roads;
Improved off-road capability for off-road driving.
9. wheel formula chassis
Depending on which car chassis the body is installed, there are formulas:
4x2, 4x4, 6x4, 6x6, 8x4, 8x8, 10x6, 10x10
10. according to the degree of preparation for work with a dump trailer or a semi-trailer dump truck.
There are versions of trucks that are not adapted to transport a trailer (mining dump truck) or, conversely, have the ability to connect several trailers (transportation of light bulk goods for Agriculture).
Structurally, the dump truck consists of a self-propelled or transportable chassis. It has a lifting mechanism and the main working body - an iron platform with high sides. Basically, as a self-propelled chassis, the base of a serial truck with installed brackets for attaching the body and the lifting mechanism is used. The latter may consist of mechanical assemblies, or the most common scheme - hydraulic assemblies.
Also, there is a combined design, where hydraulic and mechanical units are combined. The hydraulic lift consists of a hydraulic pump driven by transfer box or an electric motor, a small distributor and a multi-section hydraulic cylinder.
Control scheme lifting mechanism may be based on electrical components or on manual switching distributor levers.
Hydraulic equipment scheme
The body is an open, rectangular, all-metal tank with a flat or arcuate (concave inward) platform with blind or opening sides (side or rear). Unlike cargo bodies, in a dump truck, the side is suspended from above, on the upper hinges (apron suspension). This design, when unlocking the locking lock, opens itself when unloading under the influence of own weight or loose cargo. And when returning to the place of the body after unloading, the side rises to its original place, connects to the body and is locked by locks located below. The use of such simple mechanism allows you to save a lot of time when performing unloading work.
There are approximately the following body types:
A) Rectangular;
B) Semi-elliptical;
B) trough-shaped;
D) Bucket type;
D) Soviet type.
Rectangular body type has the largest usable volume. But it also has its drawbacks. Right angles of such a body are poorly self-cleaning.
The semi-elliptical shape was used for transporting concrete and mortar when concrete transport mixers were not widely used. Dump truck bodies with this shape are no longer produced due to their small volume, high center of gravity and lack of demand.
trough shape - golden mean between rectangular and semi-elliptical. It has no right angles, the walls are located at an angle, the useful volume is used to the maximum.
Another feature of the dump truck body is its high front side. It is often installed at an obtuse angle with respect to the platform, has a horizontal and a vertical aprons. This design allows you to protect the driver's cab from the load, and also prevents the weathering of bulk materials during the movement of the dump truck. An awning can be attached to the apron, which covers the transported cargo.
In mining dump trucks, shovel-type bodies without a tailgate are used.
His role is played by an elevated rear end platforms. In the design of such bodies, large strength characteristics are initially laid down in order to withstand huge shock loads. In addition, loaded and transported rock, stones, crushed stone, with their own sharp corners they erase the steel sheets of the body, it is then that they have a greater thickness. The scoop body has many disadvantages: large tilt angles up to 70-80 degrees (for conventional bodies 46-60°), heavy weight, suboptimal use of volume. But, the specifics of use, simple manufacturing, and robust construction offset these shortcomings.
Dump truck manufacturers have provided for the possibility of preventing wet cargo from freezing to the body. It contains special channels through which traffic fumes from a car engine.
The dump truck is a convenient and practical solution if it is necessary to carry out the transportation of bulk cargo, whether it be sand, gravel or soil. It is convenient with the help of a dump truck to take out garbage, snow from the construction site.
An important technical characteristic of the dump truck, which distinguishes it favorably from other types of trucks, is the presence of a self-tipping body. This allows the vehicle to be unloaded minimum term without attracting additional units of special equipment and labor.
The scope of dump trucks is quite wide. This machine has relatively small dimensions, due to which it is able to fit into a limited space, which is especially important when working in the city, as well as in the construction of mines and tunnels.
Specifications make the dump truck suitable for hauling heavy and oversized cargo over long distances in the shortest possible time. Therefore, the dump truck is in demand when performing road and agricultural work. It is impossible to imagine construction without the use of such special equipment as a dump truck.
Types of dump trucks
When carrying out work, it is always important to choose exactly the modification of the dump truck that is most convenient for their implementation. There are several types of dump trucks and related classifications.
Dump trucks differ from each other in the following characteristics:
- load capacity;
- scope;
- type of axial load;
- dimensions;
- body type.
There are five categories of payload:
- dump trucks with low load capacity up to 1 ton;
- dump trucks with low load capacity up to 2 tons;
- dump trucks with an average load capacity - carry cargo up to 5 tons;
- dump trucks with heavy load capacity- able to carry cargo weighing from 5 to 10 tons;
- dump trucks with a particularly large load capacity - more than 10 tons.
The next feature that distinguishes different kinds dump trucks, is their scope of use.
Mining trucks
These machines are used where high cross-country ability is needed - with mining and mining. The dump truck has a load capacity of up to 40 tons, equipped with a rear unloading mechanism. It has high cross-country ability thanks to two axles and rear-wheel drive.
Articulated dump trucks
An articulated dump truck has a higher cross-country ability than a mining one. Such a car is used in construction and quarry work. The dump truck is equipped with an articulated frame and three axles with six driving wheels.
Dump truck for underground works
Such a dump truck functions especially effectively in the conditions of limited space of mines and tunnels. Exactly there this modification car and apply. It serves for the removal and unloading of blasted or loosened rocks.
Agricultural dump trucks
A feature of the dump truck used in the field of agriculture is the ability to transport bulky, but relatively light cargo. This, for example, can be hay, feed. The dump truck has three-sided unloading of the body.
construction dump truck
A construction site requires a dump truck that is capable of transporting fairly heavy bulk cargo such as sand or gravel. Construction dump trucks are equipped with rear unloading, rarely it can be double-sided.
Among other features, dump trucks come with a crane, which makes it easier to load and unload.
Availability various modifications dump trucks makes the use of this type of special equipment especially convenient. It is always possible to choose a machine of a certain size, which has the features that allow you to carry out work quickly and efficiently at minimal cost.
A dump truck is a type of self-unloading vehicle equipped with a trailer, semi-trailer or bunker-type body. To unload, it mechanically tilts with the help of hydraulics. There are also models with forced auger unloading and telescopic lifts.
Appointment of dump trucks
Dump trucks are used to transport bulk or small-piece cargo. This may be the delivery of inert or bulk materials to the construction site, during road repair work, during the construction of infrastructure facilities. In agriculture, machines of this type are in demand during harvesting and fodder preparation, during land reclamation activities. They are used to remove snow blockages and garbage disposal utilities and large companies. Another narrow specialization of dump trucks is the opening and development of minerals in a quarry (open) way.
Types of dump trucks
Dump trucks - special equipment wide application. The versatility of its application would be impossible without certain differences in the design. Today, there are several ways to classify dump trucks.
Machines can have the following unloading methods:
- inclined,
- forced.
As a body in a dump truck can be used:
- bunker,
- platform,
- moving bunker,
- moving platform.
Body tilt methods:
- hydraulic;
- screw (or screw);
- forced;
- using a telescopic lift.
The following unloading methods are also available:
- back,
- lateral,
- bilateral,
- universal.
Depending on the purpose, the following types of dump trucks are distinguished:
- Road. The most popular type of car. Used to transport goods on the roads common use. The capacity of such a dump truck usually does not exceed 40 tons. It can be used during construction works, in agriculture in the process of harvesting, in the mining and processing industries. Such machines are often on the balance sheet of utilities. The peculiarity of these dump trucks is that they have a fairly low off-road and rough terrain.
- career(off-road). This category includes dump trucks with increased power and carrying capacity, capable of transporting up to 450 tons of materials in one go. Most often among them there are posterior and all-wheel drive models with electromechanical transmission. Mining dump trucks are characterized by low maneuverability and have significant restrictions on the speed of movement. In practice, they are often used in tandem with excavators during overburden work, when mining in an open way.
- Articulated. Equipment of this type is also commonly called earth carriers. They have an articulated frame that connects the cab and body. These units are characterized by increased cross-country ability with excellent maneuverability. Such dump trucks are capable of transporting an average of 10-50 tons of cargo, while moving with high speed even by difficult areas way.
- Underground. These are dump trucks designed for excavations in faces and cuts, subject to a small degree of inclination of the shaft. IN constructively they are tractors with a trailer on a double articulated hitch. Models of both small tonnage and large (from 1 to 40 tons) are available.
Dump Truck Characteristics
Depending on the purpose, the characteristics of dump trucks can seriously differ. The main ones include carrying capacity, weight, gross and curb weight, engine and wheelbase parameters. Let's consider them in more detail.
load capacity. For some models, this parameter can reach 450 tons, although in practice dump trucks are most in demand, capable of transporting no more than 40 tons of materials at a time.
Curb weight. The weight of equipment without cargo varies from 6 to 50 tons.
Full mass. The total weight of cargo and equipment can be up to 500 tons.
Movement speed. On average, it is 45-70 km / h.
Number of wheelbase axles. The most popular models in which there are 2, 3 or 4.
Maximum engine power. Most dump trucks are equipped with engines capable of developing from 200 to 700 hp. With.
Transmission. It can be mechanical or automatic.
As attachments dispensers are used for the dump truck. They are brackets that stop the board at the time of capsizing. This improves the accuracy and accuracy of unloading bulk materials.
Cat® Trucks
With a wide range of payload capacities, dump trucks are widely used around the world for transporting both small volumes of materials and large cargo lots. The main requirements that apply to this type of equipment are endurance and reliability. These two conditions are met by Cat® trucks manufactured by by Caterpillar. The range of this manufacturer includes off-road vehicles and equipment with an articulated frame. In the first case, these are off-road dump trucks designed for use in mining and quarrying. In the second - quite light and maneuverable machines, easy to operate and maintain. All equipment undergoes strict control and testing in difficult conditions operation.
Our catalog contains actual models Cat dump trucks®, differing in load capacity, design features and scope. To learn more about the new Caterpillar equipment, as well as to clarify the rental conditions for used cars, please contact our consultants at any of the contact numbers.
dump truck- this is a practical and convenient solution when it is necessary to carry out the transportation of bulk cargo (sand, gravel, soil). It is also convenient to take out garbage or snow from the construction site by means of a dump truck.
The main technical characteristic of the dump truck, which distinguishes it from other types of trucks, is a self-tipping body, which allows you to unload the machine in the shortest possible time and without the involvement of auxiliary units of special equipment, as well as labor.
The scope of dump trucks is quite wide. This machine has a relatively small size, due to which it is able to fit into a fairly limited space, which is especially important in urban work, in the construction of tunnels, mines. Technical indicators make the dump truck quite suitable for transporting overall and heavy loads over long distances in a minimum period. Therefore, the dump truck is in great demand for road and agricultural work. If this type of special equipment is needed for some time, then the rental of dump trucks will be more rational choice rather than owning them.
It is important to choose the actual dump truck model that is most convenient for specific work. , as well as several classifications related to them. All dump trucks differ in the following characteristics:
- load capacity;
- area of use;
- type of axial load;
- body type;
- dimensions.
Mining trucks
These machines are used where high cross-country ability is required - in mining, mining. The dump truck has a load capacity of 40 tons, equipped with a rear unloading mechanism. Excellent cross the dump truck has thanks to a pair of axles, as well as rear-wheel drive.
Dump truck that are involved in underground work
This dump truck works especially effectively in very limited spaces (mines, tunnels). Actually there this modification of the machine is used. The dump truck is intended for removal of the loosened or blown up breeds.
Articulated dump trucks
Articulated haulers have more high traffic than career ones. used this car in construction, quarry work. The dump truck is equipped with an articulated frame, as well as three axles with all driving wheels.
Agricultural dump trucks
A characteristic feature of such a dump truck, which is used in the field of agriculture, is the ability to transport large-sized, but relatively light cargo (hay, feed).
Construction dump trucks
Construction requires dump trucks that are capable of transporting rather heavy bulk cargo (sand, gravel). The construction dump truck is equipped with rear unloading, sometimes it is double-sided.
Among other features, dump trucks can be equipped with a crane.
October 30th, 2013
The BelAZ company has created the world's largest dump truck BelAZ-75710 with a carrying capacity of 450 tons, which is equivalent to three hundred Ford Focus, 37 double-decker buses or two and a half blue whales. By the way, the Airbus A380 - the largest passenger aircraft in the world - weighs much less, only 277 tons.
Let's take a closer look at this machine...
September 25 at test site The world's largest dump truck BelAZ-75710 was presented. The carrying capacity of the new machine is 450 tons. Before that, the most big trucks BelAZ-75601 (created at the Belarusian Automobile Plant in 2007) and the Swiss Liebherr T282B (appeared in 2003) were considered - both with a carrying capacity of 360 tons. total weight car is 810 tons. Soon the car will be listed in the Guinness Book of Records.
The power plant of the record BelAZ-75710 includes 2 diesel engines with a total capacity of 8500 hp, designed to supply energy to electric motors that drive the giant wheels of the truck. Max speed supercar is 64 km/h.
The BelAZ-75710 equipment includes a dead zone monitoring system, an air conditioner, an alarm about approaching a high-voltage line, and fire extinguishing systems. The largest mining truck in the world is designed to work in difficult conditions in open pits and deep quarries at temperatures from -50 to +50 degrees. 8 dump truck wheels equipped with tubeless tires, allow a heavy machine to move easily along technological roads.
BelAZ-75710 was presented in the city of Zhodino, in honor of the 65th anniversary of the Belarusian car factory, known all over the world for its heavy equipment and mining dump trucks. The appearance of big truck in the world is dictated modern conditions when the mining industry requires increasingly heavy and powerful technique. IN last years The production of ultra-heavy-duty mining dump trucks has doubled and the growth trend continues. Taking into account the market demand, BelAZ will produce about 1,000 such vehicles per year.
In order to increase the pace of production at the Belarusian enterprise, a development program has been actively implemented over the past year and a half, within the framework of which new workshops with an area of more than 30,000 square meters have been built. A lot of new equipment has appeared, and in soon it is planned to install about 700 machine tools and special technological installations. Currently, BelAZ produces the widest the lineup mining trucks. No manufacturer in the world has such a number of models. In addition, the resource of cars has grown from 400 thousand to 1 million kilometers. In total, in its entire history, the Belarusian Automobile Plant has produced more than 500 various models lifting capacity from 30 to 450 tons. For all the time, 136 thousand machines were manufactured, which are operated in 72 countries of the world.
The Belarusian Automobile Plant, the construction of which began near the city of Zhodino near Minsk (then still as the Peat Engineering Plant) in 1948, today produces products whose world analogues can be counted on the fingers of one hand.
For more than half a century of history, the Belarusian automobile enterprise near Minsk has produced over 120,000 units of mining equipment. BelAZ trucks operate in almost 50 countries of the world. And the history of the plant began in a Soviet everyday way: in 1946, the authorities decided to build a peat machine-building plant (Decree of the Supreme Council of the BSSR 11.09.1946 No. 137/308). Literally 2 years later, Belpromproekt has already completed the development and approval of the plant project. So from the planning phase, the Belarusians moved on to the construction of buildings.
The Zhodzina enterprise showed its first products in 1950, and the very next year, the Peat Engineering Plant was redeveloped into the Dormash Road and Land Reclamation Machinery Plant. In 1958, the enterprise received a new name, under which it is still known - "Belarusian Automobile Plant". The first 25-ton dump truck MAZ-525 rolled out of the gates of the enterprise with a new name.
Further more. In the same year, the production of 25-ton dump trucks MAZ-525 was transferred to Zhodino from the Minsk Automobile Plant. And in 1960, the production of the first samples of the MAZ-530 dump truck with a carrying capacity of 40 tons was launched in the Minsk region. By that time, the thousandth MAZ-525 rolled off the assembly line in Zhodino.
But an enterprise that bore the proud name of an automobile plant, one assembly trucks under the license, of course, it was not enough. Therefore, in 1960, it began to design dump trucks in principle new design for the development of mineral deposits in an open way.
However, already in April 1960, BelAZ created its own design service, which was headed by Z.L. Sirotkin, who arrived in Zhodino from Minsk together with a group of MAZ designers. The newly created department needed to solve a complex problem. Until recently considered a model new technology, MAZ-525 ceased to meet the increasing requirements of operators. Powerful mining and coal quarries, large hydrotechnical construction projects, and construction industry enterprises needed more high-performance dump trucks, most adapted, first of all, to working conditions in quarries.
The design service and the management of the enterprise decide not to improve the existing dump truck model, but to create a completely new car. This period can be called a milestone in the history of the Belarusian Automobile Plant. Factory designers studied the operating conditions and required specifications of the future dump truck, contours were born on the vertical of the drawing boards future car, on test benches, the correctness of the adopted technical solutions.
Probably, now it may seem incredible, but then, in the era of unprecedented labor enthusiasm of the first post-war five-year plans, it was an almost ordinary event: in less than one year, a fundamentally new mining dump truck with a payload capacity of 27 tons was created at a young plant under the name BelAZ-540, a prototype of which was released in September 1961.
The design of this vehicle included many new technical solutions for mechanical engineering, which subsequently ensured the highly efficient operation of the dump truck in quarry conditions. This is the first time in practice domestic automotive industry pneumohydraulic suspension, providing a high ride smoothness both in laden and empty condition, hydromechanical transmission, which was also used for the first time in the practice of our mechanical engineering for mass-produced machines, the original layout: the location of the cab next to the engine made it possible to obtain a minimum base and minimum dimensions and thereby increase the maneuverability of the machine, increase its stability, the bucket-type platform made it possible to lower the center of gravity and also increase the stability of the car. original solutions on steering and platform tipping systems, plumage and other components have become traditional when creating dump trucks of the next load capacity classes.
BelAZ-540 became the ancestor of a whole family of heavy dump trucks. In 1967, the enterprise mastered the production of a 40-ton BelAZ-548A dump truck, designed with the maximum possible unification of the main components and parts of the two machines.
1968 was the year of the birth of the BelAZ-549 prototype - a basic dump truck with a load capacity of 75-80 tons, the first sample with an electromechanical transmission. In 1977, prototypes of the BelAZ-7519 dump truck were produced - the basic dump truck with a load capacity of 110-120 tons. Six years later, the plant began mass production of BelAZ-75211, a basic dump truck with a load capacity of 170-220 tons.
By 1986, the plant could produce up to 6,000 units of such equipment per year, which accounted for half of the world's production.
They were not going to stop at BelAZ at this point. In 1963, a prototype of the second development of the plant's designers rolled off the assembly line - a BelAZ-548 dump truck with a payload capacity of 40 tons.
In 1966, the Belarusian Automobile Plant began serial production of the BelAZ-548A dump truck, a basic dump truck with a load capacity of 40–45 tons. The plant itself was awarded the Order of the Red Banner of Labor and received gold medal on international exhibition in Plovdiv for BelAZ-540.
The BelAZ-549 dump truck with a carrying capacity of 75 tons was another novelty of the Belarusian automobile enterprise. The first prototype of this machine with a carrying capacity of 75–80 tons was produced in 1968. With unique developments, the Belarusians seriously declared themselves to the entire Union, proving that such giants can be created even in a small republic.
The next stage of construction took place already in the 70s. In 1977, prototypes of the BelAZ-7519 dump truck with a payload capacity of 110 tons appeared - the base dump truck with a load capacity of 110–120 tons. So the Belarusian enterprise jumped over several weight categories in one jump.
In 1978, the plant mastered a new technique for itself - airfield tractors for towing aircraft with a take-off weight of 100 tons. Fortunately, the Belarusians already had a chassis for them. But in the race to increase the draft properties of BelAZs, it was too early to put an end to it. In 1982, prototypes of the 170-ton BelAZ-75211 dump truck, a representative of the 170-200 t load capacity class, rolled off the Zhodino conveyor.
In 1990, BelAZ completely made a splash by building a huge dump truck with a carrying capacity of 280 tons. The car turned out to be so serious that after its appearance, the ardor of engineers cooled slightly. In 1994, the Belarusians again turned to the “small” class: a prototype BelAZ-7555 dump truck with a payload capacity of 55 tons was created, the head model of a new family of dump trucks with a hydromechanical transmission. It was followed, 2 years later, by the release of the 130-ton BelAZ-75131, which became the first in a new family of dump trucks with an electromechanical transmission.
However, by the crisis year of 1998, Zhodino realized that without a serious modernization of production, the plant's future prospects were vague. BelAZ began the reconstruction of the existing production, focused on updating mining equipment, developing new models, improving quality and technical level both individual components and systems, and manufactured equipment as a whole.
As a result, in 2000 Production Association(the plant received this status in 1995) was awarded the "Crystal Nika" under the International program "Partnership for Progress", and to CEO BelAZ P.?L. Mariev was awarded the title of "Director of the Year", and later the title of "Hero of Belarus".
Flattered by the success, the Belarusians set to work with redoubled energy, and in 2002 built a BelAZ-7528 all-wheel drive articulated dump truck with a payload capacity of 36 tons, as well as a 77-ton BelAZ-7555G.
In the early 1990s, marked by the collapse of the USSR and a sharp decline in production, BelAZ did not stop producing any of the models of mining dump trucks, covering the load capacity range from 30 to 220 tons. Moreover, he included production program other special heavy transport equipment, the release of which has been mastered since the nineties of the last century: dump trucks off-road with hydromechanical transmission, road construction and mining machinery, such as loaders, bulldozers, towing tractors and water sprinklers; underground machinery, machines for metallurgical plants, etc.
Progressive solutions included in the design of the first Belarusian mining dump trucks made it possible to further improve the units and systems of machines of all load capacity classes, introduce new components and materials, gradually modernize dump trucks with the creation of new modifications based on the use of diesel engines, transmissions and tires manufactured by various companies. Special attention factory specialists have always paid attention to the adaptability of equipment to operating conditions, creating options in each class of dump trucks in northern and tropical versions, for transporting light loads, etc.
The model range of equipment produced by the Belarusian Automobile Plant was also replenished with new generation vehicles - a 55-ton mining dump truck BelAZ-7555, a mining dump truck BelAZ-75131 with a payload capacity of 130 tons, which was designed taking into account more than 15 years of operating experience of its predecessor - a 120-ton dump truck, as well as the largest mining dump truck BelAZ-75600 with a payload capacity of 320 tons in the history of the domestic automotive industry.
In total, over the entire history, the management of the chief designer of the Belarusian Automobile Plant has developed more than 600 modifications of mining dump trucks with a carrying capacity from 27 to 320 tons, the company has produced more than 130 thousand units of mining dump trucks, which have been sent to more than 70 countries of the world throughout the history of the plant.
Significantly expanded production line BelAZ, and primarily due to the underground theme, the entry into its composition of the Mogilev Automobile Plant. The department of underground and road construction equipment, which provides design support for production at the branch in Mogilev, also joined the design service of the Belarusian Automobile Plant. The special design bureau of the UGK BelAZ develops the design of freight rolling stock manufactured at the Mogilev Carriage Works, which also recently became part of the BelAZ production association.
Only recently, BelAZ has developed and manufactured pilot batches of:
90-ton dump trucks BelAZ-75570 with 6-speed hydromechanical box gear; according to the test results, training ends series production, a pilot batch of mining dump trucks was shipped to Belogorsk by Rusal Transport Achinsk LLC;
45-ton mining dump trucks BelAZ-75450 with an increased service life of up to 600,000 km, the prototype of which was successfully tested in the Chelyabinsk region of Russia at OJSC Yuzhuralzoloto;
320-ton dump trucks BelAZ-75600. The first machine of this series passed acceptance tests in operating conditions at OAO Management Company Kuzbassrazrezugol in the Kemerovo region, which showed that the use of BelAZ-75600 dump trucks provides an increase in productivity by 35-40% and a corresponding reduction in the cost of transport operations. On the basis of the main components of a 320-ton truck, a BelAZ-75601 mining dump truck with a payload capacity of 360 tons was developed, a prototype of which was made for the anniversary of the UMC.
However, it would be wrong to say that by his birth career equipment, developed and produced at BelAZ for half a century, owes only to the Belarusian land. A huge amount of research and design work in the creation of machines with hydromechanical transmission in the 60s of the last century, BelAZ was able to carry out thanks to the wide cooperation of the plant with many organizations, including NAMI, the Electric Welding Institute, the Barnaul Transport Engineering Plant, Yaroslavl engine plant and others.
The creation of the first model of a mining dump truck with an electromechanical transmission BelAZ-549 with a carrying capacity of 75 tons was carried out in accordance with the program of the State Committee for Science and Technology of the USSR with the participation of co-executors, including the Ural Turbo Engine Plant, the Dynamo plant, the Research Institute of Heavy-Duty Wheels (Dnepropetrovsk), the plant " Sibelektroprivod.
New generation equipment got a start in life at the largest mining enterprises, where prototypes were tested and the correctness of the adopted technical solutions was checked: at the Bachatsky and Neryungri coal mines, Olenegorsky, Lebedinsky and Balkhash GOKs, MMC Pechenganikel and other enterprises.
Created in 2005 scientific and technical center BelAZ, which united the department of the chief designer, the department of underground and construction and road equipment, an experimental workshop and a testing laboratory, consolidated the creative forces of not only the workers of the plant, but also mining scientific institutions of the CIS countries, such as the Federal State Unitary Enterprise “TsNII-Chermet named after A.I. I.B. Bardin", Krivoy Rog Technical University, Research and Design Institute "Yakutniproalmaz", St. Petersburg State Mining Institute, etc.
On the day of the celebration of the 50th anniversary, an exhibition of products manufactured by the enterprise was organized at BelAZ, where they showed both mass-produced equipment and new developments.
One of the new products of the enterprise was the largest mining dump truck in the BelAZ-75601 line of vehicles with a payload capacity of 360 tons.
It was designed as a machine of a higher technical level and load capacity class using the basic units of the BelAZ-75600 dump truck and component parts and assemblies from leading world manufacturers. On it are installed diesel engine MTU 20V4000 3750 hp, transmission alternating current Siemens, tires dimension 59/80R63 with a diameter of 4 meters.
And the main surprise of the exhibition of equipment was a machine of the future generation - a remote-controlled mining dump truck BelAZ-75137. This is a prototype that the company's specialists are only teaching to "walk". Further development dump truck design dictates the need to develop a fully autonomous controlled machine without human intervention. This development is designed to reduce the impact of the human factor while working in hard-to-reach places production from hazardous conditions operation, as well as eliminate the impact on the dump truck operator of harmful environmental factors.
The control system of this dump truck consists of onboard system control and working (remote) place of the operator. The opto-electronic system installed on the dump truck ensures the safety of driving the car in all weather and climatic conditions, even in the dark.
