Komatsu WA380-8 wheel loader is a mid-size articulated machine designed for material handling, loading, stockpiling, and general construction work. It is part of Komatsu's WA series and is commonly used in aggregate yards, quarries, road building, and site preparation. The WA380-8 typically features a fuel-efficient diesel engine, hydrostatic or torque-converter driveline depending on configuration, and a Z-bar loader linkage for strong breakout force and efficient bucket loading. Operator comfort, visibility, and service access are key design elements. The model is used with general-purpose, rock, and high-capacity buckets across a range of earthmoving and bulk material applications.
