WA320-8 Wheel Loader

Komatsu’s fourth generation hydrostatic drive transmission system

The hydrostatic drive line delivers 98% efficiency and also offers dynamic braking. This system is also coupled with a traction control system to reduce tyre wear in slippery applications.

Current Offers

Versatile PZ Linkage

The WA320-8 combines the best of a Z-Bar linkage and a PZ linkage while maintaining parallel lift. The bucket auto rollback feature tilts the bucket back as the boom raises to eliminate spillage, similar to a traditional Z-bar machine. Return to level can be set for both a bucket and fork or other attachment. Switching between the two is done with a switch in the cab.

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
