Construction vehicles are the backbone of construction projects. Because of their appearance, the construction progress has doubled and the manpower has been greatly reduced. Looking at the operation of the engineering vehicle, we can't help but shock the power of machines and technology. They are used for engineering transportation, excavation, emergency maintenance and even fighting. Do you know how long the longest engineering vehicle in the world is? The following is the introduction I brought to you. ? What is the longest engineering vehicle in the world? Belarus mining dump truck? Belas. Set a world record of carrying more than 500 tons. It is reported that in Belas Automobile Factory, 503 tons of goods were loaded on Belas -757 10 dump truck with a deadweight of 450 tons, and then the car began to drive around. The length of this truck is over 65 feet (about 20 meters) and the height is 26 feet (about 8 meters). Its rated load capacity is 450 tons, the self-weight of the whole vehicle is 360 tons, and the maximum working weight exceeds 860 tons. ? What is the company based on? Belaz? BELAZ-757 10, the largest dump truck in the world, was created, with a carrying capacity of 4.5 million tons, equivalent to trёmstam Ford Focus, 37 double-decker buses and one and a half or two blue whales. By the way, the Airbus A380, the largest passenger plane in the world, is much lighter, only 277 tons. ? On September 25th, the test base put forward the world's largest dump truck BELAZ-757 10. The production capacity of the new machine is 4.5 million tons. Prior to this, most large trucks were considered as Belaz-75601(founded in Belarus Automobile Factory in 2007) and Liebherr T282b (launched in 2003) -360 tons. The total weight of the car is 8 10 ton. In a short time, the machine will be listed in the Guinness Book of World Records. The power plant record BELAZ757 10 includes two diesel engines with a total capacity of 8,500 HP, which is designed to power the giant wheels of the forklift driven by electric motors. The top speed is 64 kilometers per hour. ? BELAZ757 10 equipment includes monitoring blind area, air conditioner, alarm system close to high voltage line and fire extinguishing system. The world's largest dump truck is designed to work in difficult conditions outdoors and in deep pits with temperatures ranging from -50 degrees to +50 degrees. Eight-wheeled trucks are equipped with tubeless tires, allowing heavy machinery to move forward easily on the road of science and technology. ? BELAZ757 10 was introduced to commemorate the 65th anniversary of the establishment of Belarus Automobile Factory, which is a world-famous heavy equipment for producing dump trucks. The largest truck in the world is determined by modern conditions, when the mining industry needs more and more heavy and powerful technology. In recent years, the super-high bearing capacity of dump trucks has been increased by 2 times, and the growth trend has been maintained. In view of the market demand, BELAZ will produce about 1000 cars every year. ? In order to increase production, the proportion of enterprises in Belarus has been actively promoting the development plan for the past year and a half. According to this plan, the newly built factory covers an area of more than 30,000 square meters. There are many new equipment, and it is planned to install about 700 machines and special process devices in the near future. BELAZ currently produces all kinds of dump trucks. There is no manufacturer of similar model in the world. In addition, the motor life is as high as 400,000. Up to 1 100 million dollars. Kilometers. Generally speaking, in its history, Belarusian automobile factories have produced more than 500 different models with lifting capacities ranging from 30 tons to 450 tons. There are always 136000 machines running in 72 countries. ? Autoworks in Belarus, 1948, started construction near Zhuodino and Minsk (at that time, it was a peat plant project), and the products produced can be counted with the fingers of one hand in the world. After nearly a century and a half of history, Belarusian automobile enterprises in Minsk have distributed 654.38+200,000 pieces of excavation equipment. BELAZ works in nearly 50 countries around the world. The history of this factory began in the Soviet Union: 1946, and the authorities decided to build a peat project (Belarus SSR 1946 September1,the Supreme Soviet decided № 308 № 137%). Only two years later, Belpromproekt completed the development and coordination of the project factory. Therefore, from the planning stage of Belarus to the construction of buildings. ? Its first product, Zhuodino Company, revealed that in 1950 and the following year, the peat workshop project has been rebuilding the road factory and recycling machine? Domash? . 1958, the company received a new name called-? Belarus automobile factory? The first batch of 25-ton dump trucks MAZ-525 was launched from the company's new name gate. More. -More. In the same year, Zodino moved to Minsk to produce a 25-ton dump truck MAZ-525. 1960, MAZ-530 dump truck, which started production in Minsk, carried the first sample with a capacity of 40 tons. At that time, we will come to MAZ-525 on the assembly line of Zhodino. However, the car factory and the company with the reputation of the next assembly under the license plate are not enough by themselves. So 1960 began to design the new design mine for trucks, which is an open development. However, in April of 1960, he set up his own design studio in BELAZ, headed by ZL Sirotkin, and he arrived in Zhodino from Minsk with a group of designers MAZ. It is necessary for the newly established department to solve a complicated problem. Until recently, considering the paradigm of new technology, MAZ-525 no longer meets the growing demand of operators. Forced mining and open-pit mining, large-scale water conservancy construction projects, construction companies need a high-performance car, which is most suitable for quarries with working conditions. The company's service design and management decided not to improve the existing model of trucks and create a brand-new car. This period is a milestone in the history of Belarusian automobile factory. The factory designers used the vertical drawing board to study the technical specifications required by the future automobile shape test platform for working conditions and future dumping, and verified the correctness of the adopted technical scheme. ? It may seem incredible now, but then, when the five-year plan after World War I was inspired unprecedentedly, an event was almost ordinary: in less than a year, a prototype BELAZ-540 with a brand-new name and a dump truck load of 27 tons was born in a young factory and released in September of 196 1. The design of this car has laid many new technical solutions for future mechanical engineering and high-performance trucks in quarries. This is the first time in China to provide a kind of hydraulic mechanical transmission with high smoothness in the practice of automobile gas-liquid suspension, whether loading or unloading. This is also the first time in our engineering practice that it has been used in mass production cars. Original layout: The engine room near the engine has the smallest base and the smallest size, thus improving the operability, increasing its authority to reduce the center of gravity, and also increasing the stability and sustainability of the platform bucket. For the steering system and the original solution platform tilt, feather and other websites have become the tradition of creating the load capacity of ordinary trucks. ? BELAZ-540 is the ancestor of the whole heavy truck family. 1967, the factory began to produce 40-ton truck BELAZ-548A, which was designed as the basic unit, and the two parts were as unified as possible. 1968 is the birth year of the prototype BELAZ-549, a 750,000-800,000-ton basic truck, and the first sample of organic electric drive. The prototype BELAZ-75 19 truck released in 1977 has a production capacity of10-10.2 million tons. Six years later, the factory began mass production of 1 1 base dump trucks, with a capacity of17.022 million tons. By 1986, the factory can produce as many as 6,000 such devices, which is half of the world output this year. ? This will not stop in BELAZ. 1963, the second general assembly plant designed the prototype development-dumping 40 tons of 548 Belaz-carrying capacity. 1966, BELAZ-548A truck was mass-produced by Belarus Automobile Factory. The 400,000-450,000-ton factory itself was awarded the Red Flag Medal and won the BELAZ-540 gold medal in plovdiv, which was exhibited internationally. Another novelty is the carrying capacity of BELAZ-549, a 75-ton Belarusian autoenterprises truck. 1968 released the first prototype with a load of 750,000-800,000 tons. The unique development of Belarus seriously claims to be all-alliance, which proves that a small country can also create such a giant. The next stage of construction took place in the 1970s. 1977, the prototype Belaz-7511100,000 tons capacity-base dump truck carrying capacity110/20 meters, because Belarusian enterprises leapt over several heavy categories. 1978, the factory developed a new technology-aircraft towed by aircraft tugboat, with takeoff weight 100 tons. Fortunately, the Belarusian in the chassis is already here. However, for the increase of the nature of the draft in the competition, it is too early to complete BELAZ. 1982 to Zhuodino 170-ton dump truck belaz-7521prototype, and the class representative carries1700-2 million tons of production capacity. ? In the early 1990s, which marked the disintegration of the Soviet Union and the sharp decline in output, BELAZ never stopped releasing any dump truck models with a coverage capacity of 30 to 220 tons. In addition, his production plan also includes other special heavy transport equipment, and the development of producing this equipment since the 1990s: dumping terrain and hydraulic transmission, construction machinery and mechanical mining and transportation services, such as loaders, bulldozers, tractors and polivoorositelnye machines; Mechanical underground engineering, mechanical metallurgical factory, etc. 1990, BELAZ, was a sensation and built a 2.8 million-ton truck. The car became so serious that her appearance cooled the enthusiasm of the engineers a little. 1994 Belarus turned again? Small? Category: The prototype BELAZ-7555 has a deadweight of 55 tons, a new family model truck head and a hydro-mechanical transmission device. Behind it, after a lapse of more than two years, BELAZ-75 13 1 of 30 tons followed, which became the first launch of the new series of dump trucks and electromechanical drives. ? However, in 1998, in the crisis of Zodino, I realized that the future prospect of upgrading the production plant was not vague. The development of BELAZ mining equipment, new model, quality and the technical level of its individual components and systems, the transformation of existing production types and the whole machine. Results In 2000, the Production Association (factory status: 1995) won the prize? Crystal nica? International plan? How is the cooperation going? , and Belaz's general director? A. Mariev was awarded? Best director of the year? Topic, what else? Hero Belarus? Later titles. Belarusians were flattered by their success and put into work with new energy. In 2002, they built a 36-ton four-wheel drive articulated dump truck BELAZ-7528 and a 77-ton crane BELAZ-7555G. ? In the early 1990s, which marked the disintegration of the Soviet Union and the sharp decline in output, BELAZ never stopped releasing any dump truck models with a coverage capacity of 30 to 220 tons. In addition, his production plan also includes other special heavy transport equipment, and the development of producing this equipment since the 1990s: dumping terrain and hydraulic transmission, construction machinery and mechanical mining and transportation services, such as loaders, bulldozers, tractors and polivoorositelnye machines; Mechanical underground engineering, mechanical metallurgical factory, etc. Innovative solutions were incorporated into the first Belarusian dump truck to further improve the load capacity of various system components and machines, and gradually introduce new components and materials to upgrade the truck. The creation is based on the newly modified design of diesel engines, gearboxes and tires made by different companies. Pay special attention to the running state of the expert fitness equipment in the factory, and create the dumping options for each shift with the north tropical version and light load. The equipment for manufacturing the Autoworks lineup for Belarus has also added a new generation of machinery-55t dump truck BELAZ-7555, dump truck BELAZ-75 13 1 and carrier 130 tons. This is based on 15 years' working experience, previous design ability-120 tons of trucks and the 320 tons in the history managed by the chief designer of Belarus Automobile Factory. At present, more than 30,000 dump trucks have been distributed, and more than 600 modified dump trucks have been sent to more than 70 countries in the history of the factory. ? Significantly expanded the product line BELAZ, mainly due to the underground theme, shot at Mogilev Automobile Factory. Underground and road construction equipment, design, support the production of Mogilev branch, and also join the engineering service of Belarus automobile factory. The freight vehicle being developed by UGCBELAZ Special Design Bureau, and the design works produced by Mogilev Transportation Company have also recently landed in PO? Belaz? . Recently, pilot batches were designed and manufactured in Belaz:-90t dump truck BELAZ-75570 and 6-speed hydraulic transmission; According to the test results, it is finally determined to mass-produce and transport it to Belogorsk Co., Ltd. and Russian Aluminum Corporation to transport Achinsk? Stupid; The development resources of BELAZ-75450, a 45-ton dump truck, have been upgraded to 600,000 kilometers, and a prototype has been successfully developed in Chelyabinsk, Russia, in an open joint-stock company? Uzhuralzoloto？ Testing; -320 ton dump truck BELAZ-75600. The first machine in this series has passed the acceptance test and is running in JSC? MC？ Crewe, this shows that the use of dump truck BELAZ-75600 provides 35-40%, and correspondingly reduces the cost of transportation business and improves productivity. BELAZ-7560 1 is designed on the basis of the basic unit of a 320-ton dump truck, with a load capacity of 360 tons. The prototype is the annual capacity of UGC. However, it would be wrong to say that he was born in a mining machine, developed and produced in Belarus for half a century, and only owed Belarus land. In the 1960s, a great deal of research and establishment of automobile hydraulic mechanical transmission in BELAZ failed because of many organizations in the factory, including American Electric Welding Machine Research Institute, Barnaul Transportation Project, yaroslavl Automobile Factory and other extensive society. According to the science and technology of the Soviet Union, and with the participation of subcontractors planned by the National Committee, including the Ural Factory of Turbine Engine, the first dump truck sample with 75,549 tons of electromechanical transmission BELAZ carrying capacity was manufactured. Dynamo? , SRI heavy tire (dnipropetrovsk), factory? Sibelektroprivod .？ ? The largest mining company that has started a new generation of life has tested the prototype, obtained the equipment and verified the technical scheme: Bachatskom and Neriulin coal mines, Olenegorsky, Lebedinsky and Balkhash GOKahMMC? Pechenganikel？ And other enterprises. BELAZ, a science and technology center, was established in 2005, combining its chief designer of composition control, underground and road construction equipment, pilot plant, testing laboratory and other departments. The comprehensive innovation force is not only factory workers, but also the mountain of scientific research institutions in CIS, and it is a federal state-owned unitary enterprise? Academia Sinica, their research institute. IB bardeen? Research and Design Institute of Krivorog University of Technology? Yakutniproalmaz？ St. Petersburg National Mining Institute, etc. On the occasion of the celebration, the enterprise held an exhibition on the 50th anniversary of belaz 50 50 showing commercially available technologies, newly developed and manufactured products. The novelty of a company is the technology BELAZ-7560 1 in the bank, and the largest dump truck has a load of 3.6 million tons. ? BELAZ-75600, a high-level foundation car, is designed and used, and the parts of leading manufacturers are responsible for vehicles and classes. Equipped with diesel engine MTU20V40003750 HP, driven by Siemens, the tire size is 59/80R634. The main surprise is BELAZ-75 137, the next generation art exhibition vehicle. This prototype, the company's experts taught just right? Walking? . The further development of the design determines whether a truck needs to control the machine completely independently without human intervention. The purpose of this development is to reduce the influence of human factors and eliminate the environmental factors that operators contact with hazardous wastes when working in dangerous operating conditions of narrow space production. The control system of forklift truck consists of the management and operation (remote) of operator's seat board. The photoelectric system installed on the truck can ensure the safety of the car in any weather and climate conditions, even in the dark. The diesel engine MTUDD 1 2V40001623+0623 horsepower power and new electronic fuel control and diagnosis meet the toxic substance release grade1. Variable DC applied to truck transmission also has great new designs in many different systems.
