XCMG manufactures 400-ton-capacity rigid mining truck

XCMG has designed, developed, and manufactured what the company says is the world's largest rear-wheel-drive rigid mining truck, the XDE440, customized for China Minmetals Corporation adhering to the industry standards in the high-end mining markets of South America, North America, Australia, and more. The machine can work 7,300 hours of annual working hours with a potential availability rate of over 95 percent. The machine has a loading capacity of 400 tons which is the equivalent of a three-story building.

"In order to meet such load requirements, we have independently developed the world's largest wheel reductor and strongest wet disc brake that can achieve traction which is equivalent to a fully seated 16-carriage China Railway High-speed train, and it will effectively ease transportation capacity restraints at mining sites," said Xie Heping, R&D designer of XCMG's mining machinery projects.

The XCMG R&D team has independently tackled a number of core technologies, such as intelligent variable frequency traction, high-torque wheel hub drive, cab roll protection, anti-fatigue design of large load-bearing components, and more. The XDE440 is what the company says is the world's largest tonnage AC electric drive dump truck independently developed by XCMG.

Zhang Liang, resource supply chain director of China Minmetals, noted that China Minmetals has had a long-standing partnership with XCMG since the two companies signed a strategic cooperation agreement in 2011.

As of now, XCMG has laid out a full mining equipment product range covering 70-700 tonnage mining excavators, 30-440 tonnage mining dump trucks, crushing and screening machinery of 100-6,000t/h, 350-550 horsepower graders, and more. XCMG's mining machinery products are entering mining markets including Africa, Australia, South America, and Europe.

"In the future, XCMG will go all out to provide service guarantees throughout the product lifecycle, help our customers to maximize their value, and jointly contribute to the intelligent, safe, and green development of the mining industry," said Wang Min, chairman and CEO of XCMG.
