Equipment Overview

The Komatsu WA320 is a wheel loader built for construction and general material handling work, positioned above the WA270 in Komatsu’s WA wheel loader range, current as the WA320-8. It delivers 123 kW (165 HP net) at 2,100 rpm and a 15,480–15,870 kg operating weight, suited to versatile jobsite work with a 2.3–3.2 m³ bucket capacity.

Power comes from a Komatsu SAA6D107E-3 engine meeting Tier 4 Final emission standards, driving a proven fourth-generation hydrostatic transmission (HST) with full auto-shifting, quick acceleration, and dynamic braking. Komatsu SmartLoader Logic optimises engine torque to match machine demands, minimising fuel consumption without decreasing production, and a Komatsu Diesel Particulate Filter paired with SCR keeps emissions low.
