Belarusian Automobile Plant, the construction of which began near the town of Zhodino near Minsk (then as peat Plant Engineering) in 1948 and today manufactures products world analogues that can be counted on the fingers of one hand.

For more than half a century, the Belarusian automobile enterprises of Minsk was released more than 120 000 units of mining equipment. BelAZ working in almost 50 countries around the world. A history of the plant began in the Soviet casually: in 1946 the government decided to build the plant peat Engineering (Decision of the Supreme Soviet of the Byelorussian SSR 11.09.1946 № 137/308). Just over 2 years Belpromproekt already finished the development and coordination of the project plant. So from the planning phase of the Belarusians went to the construction corps.

His first production venture Zhodino showed in 1950, and the following year the peat plant engineering plant has been redeveloped in road and drainage machines “Dormash.” In 1958, the company received a new name that is known so far – “Belarusian Autoworks”. From the factory gate with a new name rolled out the first 25-ton dump truck MAZ-525.

More – more. In the same year in Zhodino transferred from Minsk automobile production of 25-ton dump truck MAZ-525. And in 1960, in Minsk region began to produce the first samples of a dump truck MAZ-530 carrying capacity of 40 tons By the time the production line in Zhodino came thousandth MAZ-525.

But the company, bore the proud name of the car factory, the same assembly of trucks under license, by itself, was not enough. Therefore, in 1960 it started to design a truck radically new design for the development of mineral deposits open way.

However, in April 1960, at BelAZ created his own design bureau, headed by ZL Sirotkin, who arrived in Zhodino from Minsk together with a group of designers MAZ. The newly created department was necessary to solve a complex problem. Until recently was considered an example of new technology, MAZ-525 ceased to meet the increasing demands of operatives. Powerful mining and open pit mining, large hydro construction projects, to the construction industry needed a high-performance trucks, as adapted primarily to the working conditions in the mines. Service design and management of the company decided not to improve the existing model of the truck, but to create a completely new car. This period can be called a turning point in the history of the Belarusian Automobile Plant. Plant designers studied the conditions and the required technical characteristics of a future truck, were born on the drawing boards vertical outlines of the machine on the test bench tested the correctness of solutions.

Perhaps now it may seem incredible, but then, in an era of unprecedented labor enthusiasm of the first postwar five-year plan, it was almost an ordinary event: less than one year on the young plant created a fundamentally new mining truck capacity of 27 tonnes under the name of BelAZ-540, the prototype of which was released in September 1961.

The design of the car was laid a lot of new technical solutions for mechanical engineering, at a later date and high-performance truck in a quarry. It is first used in the practice of the domestic automotive pneumatic-hydraulic suspension, provide high smoothness as the laden and unladen, hydromechanical transmission, which is also the first time in the practice of our machinery has been used for mass-produced cars, the original layout: the location of cabin next to the engine allowed get a minimum base and minimum dimensions and thus increase maneuverability and increase its stability, a platform bucket allowed to lower the center of gravity and also to increase the stability of the vehicle. Original solutions on steering systems and tipping platform, feathers and other sites have become a tradition in creating the next truck load of classes.

BelAZ-540 was the progenitor of a whole family of large trucks. In 1967 the plant began producing 40-ton dump trucks BelAZ-548A, designed with the greatest possible unification of main components and parts of the two machines.

1968 was the year of birth of a prototype BelAZ-549 – the base class dump truck load of 75-80 tons, the first sample with an electromechanical transmission. In 1977, the prototypes were produced truck BelAZ-7519 – the base class dump truck load of 110-120 tons. After six years, the factory began mass production of BelAZ-75211 – base class dump truck load of 170-220 tons.

By 1986, the plant could produce up to 6,000 units of such vehicles per year, accounting for half of the world production.

On this at BelAZ not going to stop. In 1963, the production line is coming off a second prototype development engineers of the plant – dump BelAZ-548 carrying capacity of 40 tons

In 1966, at the Belarusian Automobile Plant started the serial production truck BelAZ-548A – the base class dump truck load of 40-45 tonnes plant itself was awarded the Order of the Red Banner of Labor and won the gold medal at the International Exhibition in Plovdiv for BelAZ-540.

Another novelty of the Belarusian company did was dump BelAZ-carrying capacity of 75 549 t The first prototype of this machine class load of 75-80 tonnes was released in 1968. Unique developments seriously Belarusians declared themselves to the whole Union, proving that in a small country can produce such giants.

The next stage of construction took place already in the 70s. In 1977, there were prototypes truck BelAZ-7519 capacity: 110 tonnes – the base class dump truck load of 110-120 tons Since the Belarusian enterprise in one leap leapt through several weight classes.

In 1978, the plant develops new technique – aircraft tugs to tow the aircraft with a takeoff weight of 100 tons Fortunately, the chassis for the Belarusians are already there. But in the race to increase the properties of draft BelAZ was too early to put an end. In 1982 he came off the conveyor with Zhodzina prototypes of the 170-ton dump BelAZ-75211, class representative capacity of 170-200 tons

In the early 1990s, marked by the collapse of the Soviet Union and a sharp decline in production, BelAZ not ceased production of any of the models of dump trucks, covering a range of capacities from 30 to 220 tons. Moreover, it included in the production program of other special heavy transport equipment, production of which mastered the nineties of the last century: dump terrain with hydromechanical transmission, construction machinery and equipment to service the mining and transport operations, such as loaders, bulldozers, recovery tractor and water sprinkler machine, machinery for underground works, machines for steel plants, etc. In 1990, BelAZ and did made waves by building a huge dump truck load capacity of 280 tons machine is turned so serious that after her appearance engineers ardor has cooled slightly. In 1994, the Belarusian turned again to the “small” class: a prototype truck BelAZ-7555 capacity of 55 tonnes, the head of the family model of the new trucks with hydraulic transmission. Behind her, two years later, followed by release of the 130-ton BelAZ-75131, which became the first child in the new family haulers with electromechanical transmission.

By 1998, however, the crisis in Zhodino realized that without a major upgrade of the production of the future prospects of the plant vague. BelAZ on the reconstruction of the existing production-oriented updating of mining equipment, the development of new models, improved quality and technical level of both individual components and systems, and of the machinery as a whole.

As a result, in 2000 the production association (the status of this plant was in 1995) was honored with the award “Crystal Nika” on the International Program “Partnership for Progress”, and the Director General of P. BelAz? L. Mariev was awarded the title of “Director of the Year”, and later the title of “Hero of Belarus”.

Flattered by success, Belarusians went to work with renewed energy, and built in 2002, all-wheel drive articulated dump BelAZ-7528 carrying capacity of 36 t and 77-ton crane, BelAZ-7555G.

In the early 1990s, marked by the collapse of the Soviet Union and a sharp decline in production, BelAZ not ceased production of any of the models of dump trucks, covering a range of capacities from 30 to 220 tons. Moreover, it included in the production program of other special heavy transport equipment, production of which mastered the nineties of the last century: dump terrain with hydromechanical transmission, construction machinery and equipment to service the mining and transport operations, such as loaders, bulldozers, recovery tractor and water sprinkler machine, machinery for underground works, machines for steel plants, etc.

Innovative solutions incorporated into the design of the first Belarusian dump trucks, allowed to continue to improve the components and systems of all classes of vehicles carrying capacity, introduce new components and materials, step by step to upgrade trucks with the creation of new modifications based on the use of diesel engines, transmissions, and tires manufactured by different companies. Special attention is always paid factory experts fitness equipment operating conditions, creating in each class dump options in the north and tropical version for the transport of light loads, etc.

Lineup equipment manufactured Belarusian Autoworks, also joined the new generation of machines – 55-ton dump truck BelAZ-7555, dump truck BelAZ-75131 capacity of 130 tons, which was designed with the more than 15 years of operating experience predecessor – the 120-ton truck, as well as the largest in the history of the domestic automotive dumper BelAZ-75600 load capacity of 320 tons.

In all the history of the chief designer of the control of the Belarusian Automobile Plant has developed more than 600 versions of dump trucks with load capacity from 27 to 320 tons, the company produced more than 130,000 units of dump trucks, which in the history of the plant were sent to more than 70 countries.
1382668820_008
Significantly expanded the product line BelAz, primarily due to an underground theme, to take in the Mogilev Automobile Plant. Department of underground and road construction equipment, carrying out design support production at the branch in Mogilev, also joined a design service of the Belarusian Automobile Plant. Special Design Bureau of UGC BelAz develops design of freight rolling stock, produced at Mogilev Carriage Works, which has gone down recently as part of the «BelAZ.”

Only recently at BelAZ were developed and produced pilot batches:

– 90-ton dump trucks BelAZ-75570 with 6-speed hydromechanical transmission, according to test results finalized mass production, a pilot batch of dump trucks shipped to Belogorsk Company “RUSAL Achinsk Transport”;

– 45-ton dump trucks BelAZ-75450 with increased to 600 thousand kilometers resource exploitation, the prototype of which has been successfully tested in the Chelyabinsk region of Russia on “Uzhuralzoloto”;

– 320-ton dump trucks BelAZ-75600. The first machine of this series has passed the acceptance test in operation at JSC “MC” KRU “” in the Kemerovo region, which showed that as a result of the use of dump trucks BelAZ-75600 provided a performance increase of 35-40% and a corresponding reduction in the cost of transportation work. On the basis of the basic units 320 a ton dumper designed BelAZ-75601 payload capacity of 360 tons, the prototype of which is made for the anniversary of UGC.

But it would be wrong to claim that his birth mining machinery, develops and produces a half-century at BelAZ is obliged to only the Belarusian land. A huge amount of research and development efforts to create machines with hydraulic mechanical transmission in the 60-ies of the last century BeLAZ failed due to a wide community of plant with many organizations, including the U.S., the Institute of Electric Welding, Barnaul transport engineering, Yaroslavl Motor Plant and others.

Creation of the first sample dump truck with electromechanical transmission BelAZ-549 carrying capacity of 75 tons was carried out according to the program of the State Committee of Science and Technology of the USSR with the participation of collaborators, among them the Urals Turbine plant, “Dinamo”, Institute of OTR (Dnepropetrovsk), the plant ” Sibelectroprivod. ”

Start in life for a new generation of equipment received by the largest mining companies, where the prototypes were tested and verified the correctness of technical solutions for Bachatskom and Neryungri coal mines, Olenegorsky, Lebedinskoe and Balkhash GOKah, GMK “Pechenga” and other enterprises.

Created in 2005 Science and Technology Center BelAz, united in their chief designer of controls, the department of underground and road construction equipment, pilot plant and testing laboratory, consolidated the creative force, not just factory workers, but also the mountain of scientific institutions of the CIS countries, such as the Federal State Unitary Enterprise “Central Research Institute of Ferrous-them. IB Bardeen, “Krivoy Rog Technical University, Scientific Research and Design Institute” Yakutniproalmaz “, St. Petersburg State Mining Institute, etc.

In celebration of the 50th anniversary at BelAZ an exhibition of products manufactured by the enterprise, which was shown as a commercially available technology, and new developments.

One of the new company was the largest mining truck in the line technology BelAZ-75601 payload capacity of 360 tons

It is designed as a vehicle of a higher technical level and class-duty truck using basic components BelAZ-75600 and component parts and assemblies leading manufacturers. It set MTU 20V4000 diesel engine capacity of 3750 hp, AC transmission company Siemens, tire dimension 59/80R63 4 meters in diameter.

The main surprise was art exhibition car of the future generation – the remote controlled dumper BelAZ-75137. This is a prototype that the company’s specialists are taught only to “walk.” Further development of the design of the truck dictates the need for a fully autonomous guided vehicle without human intervention. This development is designed to reduce the human impact while working in remote mining areas with hazardous operating conditions, and to eliminate the effects on the operator dump harmful environmental factors.

The control system of the truck consists of the onboard control system and working (remote) seat. Opto-electronic system installed on the truck, ensures the safety of driving a car in any weather and climatic conditions, even in the dark.

The diesel engine MTU DD 12V4000 power 1623 hp with the new electronic fuel control and diagnostics complies with the release of toxic substances Tier1. On the truck used Transmission AC DC, there are a number of new designs in the various systems of the giant.
