WA600-6 Wheel Loader

With bucket capacities from 6.4-7.8 m3, our WA600-6 loader is designed as production loading tool in hard rock quarries, sand and gravel pits, and in mining ROM 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 NZ-wide service and support network.

  • 393 kW / 527 HP
  • 54,000 kg
  • 6.4 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.
