70 Komatsu 400Komatsu America Corp. introduced the new WA600-8 wheel loader. Equipped with an EPA Tier 4 Final certified engine, the loader combines an enhanced lockup torque converter function and SmartLoader logic to achieve low fuel consumption and high travel speeds.

By optimizing control of engine power, and improving power train and hydraulic efficiency, the WA600-8 consumes up to 13 percent less fuel than its Tier 3 predecessor. The standard bucket capacity increased to 9.2 cu. yd. and now fills easier, retains material better and provides better visibility.

“With significant enhancements in production capacity and fuel economy, the WA600-8 is designed to maximize production efficiency in loading off-highway trucks or load-and carry applications,” said Rob McMahon, product manager for Komatsu America. “Full rear fenders with steps and handrails at both sides of the machine add convenience for daily inspections. And operators will appreciate enhancements in cab comfort and machine stability.”

Standard features include:

  • A powerful 23.15-liter, 529- hp, EPA Tier 4 Final certified, SAA6D170E-7 engine.
  • Komatsu Diesel Particulate Filter (KDPF) and other aftertreatment components designed in conjunction with the engine for efficiency and long life.
  • More than 98 percent of KDPF regeneration is performed passively, with no action required of the operator and no interference with machine operation.
  • Komatsu’s SmartLoader Logic, combined with the enhanced lockup torque converter, provides optimal engine torque for improved acceleration, hill-climbing ability, a higher top speed and fuel savings.
