Komatsu's New WA470-8 Wheel Loader Is Tier 4 Final

Komatsu America Corp. has introduced the new WA470-8 wheel loader. With a 272 HP Komatsu SAA6D125E-7, variable geometry turbo charged and after-cooled Tier 4 Final certified engine, the wheel loader uses up to six percent less fuel than its Tier 4 Interim predecessor. The WA470-8 is a utility performer featuring Komatsu’s SmartLoader Logic, combined with a lockup torque converter that activates in second, third and fourth gears. Working together, the system provides optimal engine torque for improved acceleration, hill climbing, a higher top speed and fuel savings.

“The WA470-8 has an outstanding combination of stability, break out power and tractive effort,” said Rob McMahon, Komatsu America product manager. “Whether you’re moving gravel, transporting pipe, charging hoppers or working with landscape materials or aggregates, the WA470-8 is the machine you want on your worksite. Available machine attachments specifically adapted for logging and waste handling applications extend the machine’s versatility,” McMahon added.

Komatsu designed the machine’s Diesel Particulate Filter (KDPF) and other aftertreatment components in conjunction with the engine for efficiency and long life. A Selective Catalyst Reduction (SCR) assembly further reduces NOx emissions using diesel exhaust fluid (DEF). The engine uses an advanced electronic control system to manage the air-flow rate, fuel injection, combustion parameters and aftertreatment functions to optimize performance, reduce emissions and provide advanced diagnostic capability.
