WA380-8 Wheel Loaders

Now with a low emission Tier 4 Final-compliant Komatsu engine, our 2.7-3.6 m3 capacity WA380-8 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 NZ-wide service and support network.

    BUCKET CAPACITY

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
