The Komatsu WA320-8 is a mid-size wheel loader used for quarry, aggregate and construction material handling. It is the class of loader that fleets use for loading trucks, stockpile work and general site loading.
Komatsu's Oceania brochure gives a net power of 165 hp (123 kW) at 2,100 rpm from its SAA6D107E-3 engine. The operating weight is given as 15,480 to 15,870 kg across bucket options, so the figure here is the lower end of that range. Heaped bucket capacity runs from 2.3 to 3.2 m³ depending on the configuration.
Komatsu's European page lists older figures, including a different gross power and a different weight range, which suggests a separate specification. Check the market and the bucket option against the brochure before comparing.
