Chinese equipment supplier XCMG designed, developed and manufactured the world’s largest rear-wheel drive rigid mining truck, the XDE440, customized for China Minmetals Corp. With a loading capacity of 400 metric tons (mt), XCMG said the AC electrically driven XDE440 can guarantee 7,300 hours per year with a potential 95% availability rate.

“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 for XCMG’s mining machinery projects.

The XCMG R&D team has developed several 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.

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