One of Komatsu's first next-generation wheel loaders was on display at this year's World of Asphalt, showcasing its greater power, lower fuel consumption and improved climbing ability compared to its predecessors.
The 6.4- to 7.2-cubic-yard WA485-11 replaces the WA480-8 and comes with the Komatsu Hydrostatic-Mechanical Transmission, which switches to hydrostatic when high torque is needed and to mechanical for increased fuel efficiency during lighter use.

The WA485-11 runs on a 363-horsepower Komatsu engine, a 64-horsepower boost over the WA480-8. Despite the power increase, it delivers 12% lower fuel consumption, the company says, and a 13% increase in climbing speed.
Visibility has been increased by adding a lower glass area and by eliminating two rear pillars, and in-cab noise has been reduced, according to Komatsu.
The bucket has been redesigned with a cross-sectional shape for increased digging efficiency and using it with the auto-digging system can help boost productivity, especially for inexperienced operators.
For increased productivity, the WA485-11 can be configured as a yard loader, with larger buckets; heavier counterweights; wide, low-profile tires and rims; and a reinforced frame. The YL configuration is best for quarry and aggregate uses and is designed to load matching on-highway trucks in three passes.
