SPIC South coal mine AT-150 truck: haul road and ramp design notes for planners

30 Second Briefing
China’s first all-electric, bidirectional, cabless rigid mining truck, the AT-150, has entered autonomous operation at State Power Investment Corporation’s South coal mine, developed jointly with truck OEM Inner Mongolia North Hauler and AHS specialist EACON. The unmanned AT-150 removes the operator cab entirely and runs on a fully electric drivetrain, integrating OEM-agnostic autonomous haulage software for route planning, obstacle detection and fleet coordination. For mine planners, the bidirectional layout and cabless design allow shorter turning radii, narrower haul roads and potentially steeper ramp geometries, tightening geotechnical and traffic design envelopes.
Technical Brief
- Joint development team combines SPIC (mine owner), North Hauler (rigid truck platform) and EACON (AHS stack).
- Vehicle architecture is rigid-frame rather than articulated, targeting large open-pit coal haul profiles.
- OEM-agnostic AHS from EACON allows integration with mixed fleets rather than a single-brand haulage system.
- Cab deletion frees deck space for additional battery modules or power electronics within existing truck envelope.
- Bidirectional capability is intended to reduce non-productive manoeuvring time at dump and loading points.
- Similar cabless rigid concepts could materially relax minimum-width and turning-radius constraints in future open-pit designs.
