KOMATSU WA320PZ-6 WHEEL LOADER

Technical Description

The Komatsu WA320PZ-6 is a versatile wheel loader equipped with a Komatsu SAA6D107E-1 turbocharged, aftercooled, direct injection diesel engine delivering 167 hp (125 kW) net power at 2000 rpm. It features a hydrostatic drive system with a 1-pump, 2-motor electronically controlled design for efficient power transfer and high tractive effort, allowing responsive travel and pushing force. The loader’s operational weight ranges between 32,480 and 33,900 lbs (14,733 to 15,377 kg), balancing robust construction with maneuverability. It has a rated bucket capacity between 3.25 and 3.50 cubic yards (2.0 to 2.7 m³) with a dump clearance at maximum raise of approximately 9.2 ft (3.0 m), ideal for efficient loading and material handling. The WA320PZ-6 is built with Komatsu’s parallel-lift PZ arm system providing stable and smooth lifting action. Its full-hydraulic power steering ensures precise control with a steering angle of about 38.5 degrees. The machine operates with a 4-wheel drive system, semi-floating, fixed axles, and planetary gear single reduction for excellent traction and stability. The transmission supports up to 23.7 mph (38 km/h) max travel speed with automatic protection for powertrain components. The operator cabin height is approximately 10.5 ft (3.2 m), offering visibility and comfort. Typical dimensions include a wheelbase near 9.95 ft (3.03 m), an overall length up to about 25.5 ft (7.77 m), and width around 8.5 ft (2.6 m). Standard wet disc brakes and hydrostatic transmission enable smooth and reliable operation across demanding construction and material handling tasks.
