Komatsu’s two new general-purpose wheel loaders featuring low-emission Tier 4 final engines, deliver lower fuel consumption than the previous generation equivalents, the manufacturers say.

The 143kW WA380-8 with an operating weight of 18.35 to 19 tonnes is powered by a Komatsu SAA6D107E-3 engine rated at 143kW net, and the model’s fuel consumption is significantly lower than its previous model, the WA380-6.

The 203kW WA470-8 with an operating weight of 24.2 to 25.2 tonnes is powered by
a Komatsu SAA6D125E-7 rated at 203kW net, and has a six percent improved fuel consumption over the WA470-7.

"The engines on both loaders incorporate Komatsu’s electronic control system performing high-speed processing of all signals from sensors installed in the vehicle, providing total control of equipment across all conditions of use," Richard Feehly, Komatsu Australia’s national business manager, quarries, says.

Other fuel-saving features include Komatsu’s closed-centre variable displacement pump technology for the hydraulics, delivering precise hydraulic flow when required, and an auto idle shutdown function along with operator comfort and control enhancements.

"In addition to these enhanced operator features, we’ve also worked to make servicing and maintenance on the WA380-8 and WA470-8 easier, safer, and faster, further contributing to reducing owning and operating costs," Richard says.

"With these two new machines, Komatsu brings the latest advances in emissions reduction, fuel saving, machine management, and productivity improvements to these very popular classes of loader."
