XCMG [Media Insight] Customer-centered technological breakthroughs are the plus points in the construction of the entire mine transportation industry.
March 15, 2023
“Efficient、Low cost”It is an eternal topic in the mining and transportation process.，It is also a global heavy equipment.、Mining dump Truck manufacturers continue to tackle key problems、The direction of technology deep search。
Off-highway（Mine use）Dump Truck products originated from abroad.，It has developed for decades in foreign countries.，The basic technology is already very mature.。China began to develop it in the 1970s.，It did not form a certain scale until the 1990s.。So far，Mass production of off-highway in China（Mine use）There are dozens of dump Truck enterprises.，Including North Heavy Truck, which was the first to tackle key problems in this field.、Benxi、Xiangtan Electric Power and other old brands and Xugong、Trinity、Tongli、Lingong and other enterprises。
With the continuous breakthrough of technology，The three-bridge Dump Truck has been upgraded and improved continuously.，It has become the main equipment for open-pit mining in China.，From the structural form, it can be divided intoWide-body Dump Truck and three-bridge rigid mining Dump Truck，At a higher transport capacity、Better security、Introduce new processes and technologies for lower maintenance costs, etc.，Break that traditional highway wide-body dump truck“Change the height without permission，Widening，Realize overload”Limitations of。Sanqiao dump truck has better load capacity and higher transport speed.，At the same time, security has been improved.。At present, the more mature brand of Sanqiao Mining Vehicle in the market is Tongli.、Xugong、Temporary worker、Trinity，It has developed from about 30 tons to about 70 tons.，Just a few years，It fully demonstrates that the mine transportation market meets the needs of users、The trend of large-scale equipment development。
It is worth mentioning that，XCMG has innovatively developed a new category of mine car products.--Three-bridge rigid mine dump truck，Advantage Technology of Introducing Double-axle Rigid Mine Car，Make the rated load of the product 90-100 tons，Satisfy the mining area“Efficiency and safety”Take into account the requirements at the same time，In addition, the mature power transmission system matching and economic cost control methods of wide-body dump trucks are introduced.，It reduces the use cost of the whole Vehicle and the difficulty of subsequent mature supporting services.，Solve the customer's worries。
The biggest difference between XCMG Sanqiao rigid mining dump truck and traditional wide-body mining dump truck lies inA rigid frame is used+Full hydro-pneumatic suspension；Steel plate、The box-section frame welded by cast steel parts is derived from the rigid mine car technology.，It is more suitable for off-highway mine conditions than the riveted channel steel frame of the wide-body Vehicle.，The overall stress level is 70% lower than that of the wide-body vehicle industry%；
The three-axle full hydro-pneumatic suspension system is the most obvious technical feature of XCMG three-axle rigid mine car.，Large telescopic stroke of hydro-pneumatic suspension，Ood buffering and damping performance，The impact of the frame on the ground is small，And that service life of the frame is prolon，Reduce the torsional deformation of the frame，Raise the engine、Gearbox life，Reduce maintenance costs and mitigate impact，Reduce bumps，Ensure that the equipment has good ride comfort，Improve the working conditions of drivers，Can maintain high vehicle speed operation，And that operation efficiency is high。Finally, XugongThe overall performance of the three-axle mining dump truck can reach 80% of that of the double-axle rigid mine car%，But the cost is less than 50 percent%；The price of the whole car is higher than that of the wide-body car.，But performance、Reliability has been doubled.，Therefore, since the listing,，XCMG Mining Machinery equipment as“Industry upstart”Quickly seize the market，Mainstream mines that have successfully entered the global high-end market。
With the country's emphasis on environmental protection and sustainable development,，Mine car manufacturers are also stepping up research and development of clean energy technologies.，The market is introducing a number of new models of pure electric and methanol hybrid power.，For example, Xugong pure electricXDR80TEThree-axle rigid mine car、Sany pure electricSKT90EEtc，Blow up in mine construction“Safe、Environmental protection、Intelligence”A whirlwind of green。
