Komatsu Smart Quarry Autonomous: Scalable autonomy for quarry haul trucks

Komatsu and autonomy developer Pronto announced Komatsu Smart Quarry Autonomous for North American quarries.

The quarry industry faces unprecedented pressure: labor shortages, safety risks, and volatile demand. Komatsu’s Smart Quarry Autonomous Solution – developed with Pronto AI – delivers a transformative retrofit autonomy system that converts existing haul trucks into self-driving assets. This technical breakthrough combines rugged on-vehicle intelligence with centralized fleet orchestration, enabling mines to boost productivity by 25% while eliminating high-risk operator tasks.

Core Technology: Modular Autonomy Architecture

The system deploys a two-tiered architecture for resilience:

• Vehicle Intelligence Tier:
  • Redundant sensor suite: LiDAR, radar, cameras, and RTK-GNSS fuse data for all-weather perception
  • SIL-2 safety controllers execute fail-safe braking and collision avoidance
• Smart Quarry Cloud Tier:
  • AI-powered dispatch optimizes haul cycles in real-time
  • Digital twin monitors every asset across the operation

Unlike fixed-route systems, Komatsu’s solution dynamically navigates variable quarry terrain using real-time map matching, maintaining centimeter-level accuracy even during GPS dropouts.

Key Operational Benefits

1. Productivity Surge:
   • 24/7 operations reduce idle time by 40%
   • Consistent 35-second load/unload cycles
   • 15-30% higher tons hauled per hour
2. Safety Transformation:
   • Geofenced exclusion zones around personnel
   • Predictive obstacle avoidance at 200m range
   • Zero recorded incidents in pilot sites
3. ROI-Driven Metrics:KPIImprovementCycle Time Variance↓ 40%Fuel per Ton↓ 18%Tire Wear↓ 22%

Seamless Deployment Pathway

Komatsu’s phased retrofit approach minimizes disruption:

1. Site LiDAR mapping & digital twin creation (2-4 weeks)
2. Truck sensor installation with Komatsu-certified technicians
3. Shadow-mode validation (AI observing drivers)
4. Incremental autonomy activation

“The system paid for itself in 14 months through labor efficiency and reduced damage costs,” reports a Nevada aggregate site manager running 12 retrofitted trucks.

Future-Ready Operations

With encrypted over-the-air updates and compatibility across mixed fleets, Komatsu’s solution scales as quarries expand. The integrated data analytics portal uncovers new optimization opportunities – from route adjustments to predictive maintenance triggers.
