Shuanglin autonomous multi-axle mining truck: haul road and ground design notes Reviewed by Tom Sullivan First reported on International Mining – News 30 Second Briefing Shuanglin has unveiled an autonomous, battery-electric multi-axle mining truck using distributed drive technology, entering a niche previously explored by China Space Sanjiang Group’s 220 t WTW220E (16 wheels in eight pairs) and ETF’s 218 t MT-240. The new platform targets ultra-heavy haul with multiple driven axles to spread ground pressure and improve traction on weak pit floors, while removing the mechanical drive train. For mine planners and geotechnical teams, such configurations could materially change haul road design, turning radius constraints and underfoot bearing capacity assumptions. Technical Brief - CSSG’s WTW220E prototype is rated at 220 t payload with 16 wheels in eight pairs. - Only two WTW220E units are believed to have been built at Wuhan, Hubei Province. - ETF’s MT-240 is a 218 t class truck, comparable in payload to the WTW220E concept. Our Take The 16-wheel, multi-axle configuration similar in class to ETF’s MT-240 suggests a design path aimed at spreading ground pressure, which could make these trucks attractive for mines with weaker haul road conditions or stricter geotechnical constraints on dump and ramp design. An estimated build of only two WTW220E units indicates this is still at a prototype or early pre-commercial stage, meaning operators considering such platforms should plan for higher integration risk and limited field performance data compared with established 220 t diesel fleets.
