Komatsu’s WA500-8 wheel loader

May 3, 2016  By  Andrew Macklin

May 3, 2016 – Komatsu America Corp. has introduced the new WA500-8 Wheel Loader, equipped with an EPA Tier 4 Final certified engine. This latest addition to the wheel loader family combines an enhanced lockup torque converter function and SmartLoader logic to achieve low fuel consumption and high travel speeds.

The standard bucket capacity increased to 7.6 cubic yards and the bucket now fills easier and retains material better, contributing to machine efficiency and productivity gains of up to 10 per cent. Also, by optimizing control of engine power, and improving power train and hydraulic efficiency, the WA500-8 consumes up to five per cent less fuel than its Tier 4 interim predecessor.

“The WA500-8 is made for loading on-highway trucks or smaller rigid trucks in quarry applications, articulated trucks on construction sites, or load and carry applications,” said Rob McMahon, product manager for Komatsu America. “Operators will also appreciate enhancements in cab comfort and features like the integrated load meter and full automatic digging function,” McMahon said.

Standard features of the new WA500-8 include:


Under The Hood

  • A 357 hp, EPA Tier 4 Final certified, SAA6D140E-7 engine uses up to five per cent less fuel than its Tier 4 Interim predecessor;
  • An engine that reduces Nitrogen Oxides (NOx) by more than 80 per cent from the Tier 4 Interim model;
  • An improved Komatsu Diesel Particulate Filter (KDPF) with increased capacity and other after treatment components are designed in conjunction with the engine for efficiency and long life;
  • More than 93 per cent 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 lockup torque converter that activates in 2nd, 3rd and 4th gear, provides optimal engine torque for improved acceleration, hill-climbing ability, a higher top speed and fuel savings.

In-Cab Enhancements/Features

  • New, air-suspension, high-back heated seat that softens machine vibration for operator comfort and new cast frame members are added for increased strength;
  • Seat-mounted electronic pilot control levers with F-N-R switch for operator ergonomics and convenience;
  • KOMTRAX telematics system and monitor that provides key machine metrics, including KDPF status and DEF-level data, fuel consumption, plus performance information collected and sorted by Operator ID;
  • Komatsu Auto Idle Shutdown to reduce idle time and save fuel;
  • Auxiliary jack and two 12-volt outlets;
  • Seven inch, full color, high-resolution monitor with Ecology Guidance;
  • Dedicated, full-color, rear-view monitor is standard.

Additional Features/Benefits

  • Swing-out cooling fan, with wider fin spacing and a standard auto-reversing fan, for ease of cleaning;
  • Gull-wing engine doors provide quick, convenient access for daily checks and service items;
  • Full-rear fenders, standard;
  • Sight gauge at DEF fill cap to minimize overfilling.

The WA500-8 is covered by the Komatsu CARE program for the first three years or 2000 hours, whichever comes first. Komatsu CARE includes limited scheduled factory maintenance, a 50-point inspection at each service, and two complimentary Komatsu Diesel Particulate Filter exchanges and two factory recommended services of the Diesel Exhaust Fluid (DEF) system during the first five years.
