Komatsu America Corp.
Launches New Models . . .
. . .
and Komatsu Japan
Gives a Hint of what’s to
come
Komatsu America unveiled new large size machines at MinExpo which Contractors
World will review in the next issue. In the mean time, the company has also announced the WA470-7 wheel loader.
With a net horsepower of 272 hp (203 kW), it is powered by a Komatsu SAA6D125E-6 engine and is EPA Tier 4 Interim
and EU Stage 3B emission certified. Built upon a proven Tier 3 engine platform, Komatsu has used its experience in
technology and innovation to design a more environmentally-friendly engine that increases power while decreasing fuel
consumption by approximately 8 percent, compared to the WA470-6.
With an operating weight of 52,007 pounds (23,590 kg), the WA470-7 features improved efficiency, lower fuel
consumption, improved operator comfort, and enhanced serviceability to maximize productivity while lowering
operating costs.
It is equipped with the KOMTRAX technology, which is fully integrated with Komatsu’s Tier 4 technology.
Bucket capacity is up to 4.4 m³, dump height 4.36 m and forward reach 2,940 mm (specification dependent up on
configuration).
EPA Tier 4 Interim and EU Stage 3B Emission Certified Engine
Built upon proven Tier 3 technology, the SAA6D125E-6 engine provides lower emissions while also lowering fuel
consumption. The Komatsu Tier 4 Interim engine uses an advanced electronic control system to manage air flow rate,
fuel injection, combustion parameters and aftertreatment functions to optimize performance, reduce emissions, reduce
fuel consumption and provide advanced diagnostic capability.
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 that will not interfere with daily operation but will
keep the operator aware of its status.
The new models features Komatsu Smart Loader Logic (KSLL), which provides optimal engine torque for the job
required. KSLL allows for fuel reduction by decreasing engine torque when the loader is not working hard, such as
when it is driving with an empty bucket. It functions automatically
with machine operation and results in saving fuel without
decreasing production.
Large Capacity Torque Converter with
Lock-Up
The WA470-7 has a newly designed Komatsu Large Capacity
Torque Converter with Lock-Up as a standard feature. This
provides improved acceleration, faster hill climb ability, a
