Powered by a low emission Tier 4 Final-compliant Komatsu engine, Komatsu’s 4.5-7 m3 capacity WA500-8 is designed for production and sales loading applications in the quarry and aggregates sectors, as well as other industries that need a loading tool that delivers power and performance. 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.

    Features and benefits

    Large capacity lock-up torque converter

    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 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

    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
