WA470-8 Wheel Loaders

With its new technology Komatsu engine, our 3.8-4.7 cu m capacity WA470-8 is well-suited to sales loading, logging, waste and mulch handling applications. As with all our wheel loaders, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our KOMTRAX remote monitoring and location system, backed by our Australia-wide service and support network.

  • 24,670 kg
  • 4.7 m³

Large Capacity Lock-Up Torque Converter

The Komatsu-designed power train features a large capacity torque converter for optimum efficiency. The large capacity torque converter allows the loader to up-shift gears faster for improved acceleration and hill climbing ability. In most applications, production is increased and fuel consumption is reduced, resulting in improved fuel efficiency

Komatsu SmartLoader Logic

Komatsu's SmartLoader Logic controls engine torque to match machine demands. This system optimises engine torque for all applications to minimise fuel consumption. Komatsu's SmartLoader Logic functions automatically and doesn't interfere with operation, saving fuel without decreasing production

Komatsu Diesel Particulate Filter and Selective Catalytic Reduction System

The KDPF and SCR reduces particulate matter and NOx while providing automatic regeneration that does not interfere with daily operation
