Komatsu Europe International announces the launch of the new WA380-7 wheel loader.
Weighing 17,910 kg, the WA380-7 features improved efficiency, lower fuel consumption, improved operator
comfort, and enhanced serviceability to maximize productivity while reducing operating costs.
With a net horsepower of 143 kW, the WA380-7 is powered by a Komatsu SAA6D107E-2 engine and is EU
Stage IIIB/ EPA Tier 4 Interim emission certified (S3B).
Using a proven Stage IIIA engine platform, Komatsu has used its leadership in technology and innovation
to design, what it claims is an environmentally friendly engine that increases power while lowering fuel
consumption by approximately 10 per cent, compared to the WA380-6.

Built upon proven Stage IIIA technology, the SAA6D107-E2 engine, Komatsu say that this provides lower
emissions while also lowering fuel consumption. This is achieved by the Komatsu S3B engine use of advanced
electronic control systems to manage air flow rate, fuel injection, combustion parameters and after-treatment
functions to optimize performance, reduce emissions and fuel consumption, and provide advanced diagnostic
As a leader in hydraulic technology, Komatsu has also developed a hydraulically actuated Komatsu Variable
Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve, resulting in better precision
and air management as well as longer component life. The Komatsu Diesel Particulate Filter (KDPF) has an
integrated design
The new loader also features Komatsu SmartLoader Logic, which provides optimal engine torque for the
job required. This system helps to save fuel by automatically decreasing engine torque when the loader is
not working hard, such as when it is driving with an empty bucket. It functions automatically and does not
interfere with operation, saving fuel without decreasing production.
Large Capacity Torque Converter with Lock-Up
The WA380-7 has a newly designed Komatsu large capacity torque converter with lock-up as standard. This
should improved acceleration under load and hill climb ability, a higher top speed and lower fuel consumption.
