China’s state-owned Xuzhou Construction Machinery Group (XCMG) reported it designed, developed and manufactured the world’s largest rear-wheel-drive rigid mining truck, the XDE440, customized for China Minmetals Corp. With a capacity of 400 metric tons (mt), the electric truck can operate 7,300 hours per year with a possible 95% availability rate, the company said.
The unit features the world’s largest wheel reducer and the strongest wet disc brake, XCMG said. The brake gives the traction needed to stop “a fully seated 16-carriage China Railway high-speed train.”
The truck also features intelligent variable frequency traction, high-torque wheel hub drives, cab roll protection, and anti-fatigue large load-bearing components.
The OEM and China Minmetals first partnered in 2011. The XDE440 will ease haulage capacity restraints at the miner’s sites and elsewhere, XCMG said.
