WA380-6 Wheel Loaders

Komatsu’s WA380-6, offering bucket capacities from 2.7-3.6 cu m, is ideal for a wide range of general purpose loading and handling operations, including civil construction, local government, sales loading, concrete batch work, log handling, waste and recycling. 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.

  • 18,630 kg
  • 3.6 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
