Development trend of dump trucks in the hottest mi

Development trend of mine dump truck

in the past few years, in order to seek better economic benefits through the 2014 development plan of graphite industry in Heilongjiang Province, many mining companies have been tending to larger-scale mining operations

it is expected that in the next few years, the output of mineral products of these large enterprises will reach the peak. When the market returns to normal, the demand of China, India, Brazil and other developing economies will continue to pose a challenge to the sufficient supply of mineral products. If miners want to calmly deal with these challenges, they should consider increasing investment in new technologies and infrastructure

in the field of highway transportation, a new generation of intelligent giant mine trucks suitable for the needs of the site has come out. This kind of mine dump truck is lighter, larger, more fuel-efficient and has less tire wear. At the same time, the manufacturer has recently taken some improvement measures for this kind of truck, and equipped with advanced computer operating system for maintenance and automatic operation

for the mining industry, mining truck automation is a new and important field. Around the world, the first generation of intelligent trucks are being put into use

the key to automation in 2008, caterpillar and the Robotics Institute of Carnegie Mellon University became partners, and they cooperated to develop large automated hauling trucks. It is expected that in the next few years, the load capacity of automated trucks will reach 240 tons or even more

"in order to meet the growing demand, a new generation of intelligent giant trucks is emerging." The relevant person in charge of caterpillar said. Researchers at Carnegie Mellon University are studying the existing autonomous mining and transportation system based on the plan and autonomous software architecture originally developed for the U.S. military. Mining giants hope to see the application of automated trucks in their mining areas by next year. Rio Tinto has been using driverless trucks imported from Komatsu of Japan in the development of iron ore in peabane, Australia. After more than a year of application, it has achieved good results

although automatic trucks have some problems when they are first used in other parts of the world, people increasingly feel that compared with traditional trucks, automatic trucks can be safer, more environmentally friendly, and easy to maintain

each Komatsu mining vehicle is designed according to the standard of vehicle health monitoring system (VHMS type), which can use satellite communication system and can be downloaded wirelessly. This model enables technicians to easily check the pressure and trend, summarize the payload of the previous day, and immediately inform the key cause of the failure using a simple interconnection interface

the computing function of Caterpillar's Audi A4 is 50 times that of its predecessor. The new module can monitor more than 30 important engine functions, drive 20 fuel injectors and exchangers, and display more than 100 engine parameters. The system will record the health of the engine and help diagnose problems. From the perspective of people's hope to continuously increase the intelligent requirements of mining vehicles, this will undoubtedly be the way forward

the bigger the better. It is expected that the scale of mining trucks will increase significantly in the next few years, which will have a far-reaching impact on the future development of automation systems

people increasingly feel that automatic trucks can be safer and more environmentally friendly. Although caterpillar and Carnegie Mellon University are seeking to manufacture automated trucks with a load of about 240 tons, it is not difficult to imagine that larger trucks with remote control will be popular in the future. Liebherr, a Belgian mining equipment manufacturer, claims that its flagship product t282b is the largest diesel electric truck currently being produced in the world, with a load capacity of 363 tons (equivalent to the load capacity of more than 210 minivans). The "big guy" car is nearly 8 meters tall and 15.3 meters long. It has six tires, each with a diameter of 4 meters, and is towed by a huge 3650 horsepower diesel engine. Dr. Vladimir bocras, Liebherr's manager in charge of mining equipment analysis and simulation, said: "it's huge, and you'll feel like driving a two-story house."

when designing these giant machines, one of the main requirements is that the total weight of the car cannot exceed the carrying capacity of the tires. The payload of the vehicle can be increased every 1kg of weight reduction of the vehicle itself. T282b weighs 12% less than similar mining trucks, which is an obvious advantage, because light trucks can also save fuel when returning empty, which greatly extends the service life of tires. This will be a major cost savings, because each of these large tires is worth thousands of dollars

the vehicle designed by Liebherr is operated by two parallel control levers according to the principle of kinematics. When the vehicle turns, the torque and the speed of the traction motor are automatically adjusted through different drive wheel control systems, so as to minimize the wear of tires. Many manufacturers have also taken this opportunity to promote and boast about how Liebherr has made significant improvements to its engines, and how its engines have the advantages of fuel economy and low emissions

when miners face more environmental challenges that cause impact during mining and look for opportunities, they will hope that mining vehicles can have better functions to meet these challenges. Take ore as an example, it is a commodity rich in new profit points, but in order to "eat dry and squeeze out", new equipment and technology are needed

suppose that the truck is going to cross a clay layer and peat in northern Canada and set the force measuring pointer to "zero" marsh to mine oil sands. Driving across this area is often described as "driving on a mattress". The challenge of design engineering is how to integrate various advanced functions of light trucks, such as different wheel control systems. You know, it is a thorny problem to let light trucks pass under this condition, so most mines will not choose mechanical trucks under this condition

electric vehicles and mechanical vehicles people now feel that diesel electric vehicles are easier to operate and generally better than mechanical vehicles, especially when encountering steep terrain, diesel electric vehicles will score higher. In addition, the price of diesel electric vehicles is not too high. They are usually easier to maintain, provide better fuel efficiency, and have less carbon emissions

Liebherr reported that its sales of super first-class diesel electric vehicles have increased from 10% to 15% in the past five years. The 960e-1 (960e) AC electric drive truck recently launched by Komatsu Corporation of Japan is its largest "fleet", which weighs 360 tons and can weigh up to pounds when fully loaded. "The effective load of 960e is still more than enough. Its strong productivity and great power are specially tailored to meet the competitive needs of today's mining industry." The person in charge of the company said

as a pioneer in the manufacturing of mechanical mining trucks, Caterpillar also recently revealed a series of information about its diesel electric vehicle roadmap developed based on the new 795f communication platform. The company said that this diesel electric vehicle adopts a series of new technologies, including four corner hybrid (curve) braking, computer-controlled oil immersion and cooling disc brakes, together with electrical flame retardant devices, which will greatly improve the safety performance of diesel electric vehicles and enhance the confidence of operators. In addition, the generator installed remotely makes it possible not to consider the maintenance of other main components. However, the wheel motor installed inside the axle can make the terminal easier and independent maintenance

caterpillar said that they would still be committed to the manufacturing of mechanical vehicles, but also stressed that in order to meet the needs of more customers, the company would also expand its production scope to the field of diesel electric vehicles. "Mechanical drive mining trucks will meet the needs of the vast majority of users in mining operations. However, as the only manufacturer of 181-t and larger mining trucks that take into account mechanical and electric drive systems, in the near future, we will be able to provide trucks that can meet the preferences of all mining companies." The person in charge of caterpillar said
