Chinese mining and construction equipment maker has released its XDE440, which it is calling the world’s largest rear-wheel-drive rigid mining truck, and has rolled the first unit off of the assembly line.
XCMG, which designed, developed and manufactured the XDE440, customized the first truck for China Minmetals. The machine adheres to the highest industry standards in the high-end mining markets of South America, North America, Australia and others, and can guarantee 7,300 hours of annual working hours with a potential availability rate of over 95%.
With a loading capacity of 400 tons, the XDE440 beats a loading capacity record that had previously been claimed by BELAZ with its 450-t 75710 model several years ago, according to the OEM.
“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 XDE440 is now the world’s largest tonnage AC electric drive dump truck independently developed by XCMG, it said.
XCMG has a full mining equipment product range covering 70-700 tonnage mining excavators, 30-440 tonnage mining dump trucks, crushing and screening machinery of 100-6,000 t/h and 350-550 horsepower graders.
