Komatsu’s newest wheel loaders are built for productivity in aggregates applications
A new engine and transmission reduce fuel consumption while boosting power
Komatsu introduced the WA485-11 and WA475-11 wheel loaders this spring at Komatsu Quarry Days and displayed the WA485-11 at AGG1. Komatsu says that these new machines are built for increased productivity, operator comfort, and maintenance ease with the ultimate goal of reducing customers' total cost of ownership.
Both models are available in a yard loader configuration with a larger bucket; wide, low-profile tires; and additional counterweight.
A new Komatsu engine and the Komatsu Hydrostatic-Mechanical Transmission (KHMT) reduce fuel consumption while boosting power. The WA485-11 offers up to 12 percent lower fuel consumption, 21 percent more engine power, and 13 percent faster climbing speed compared to its predecessor, the WA480-8. The WA475-11 provides up to 7 percent lower fuel consumption, 18 percent higher engine power, and 40 percent greater climbing speed compared to the WA475-10.
A redesigned cab gives operators excellent visibility. The elimination of two posts expands the view to the rear of the machine, and operators will also appreciate the rear-object detection system that comes standard.
The new cab offers low-effort drive-by-wire angle feedback joystick steering, independent work control, and a heated and ventilated adjustable seat to keep operators comfortable and reduce fatigue. A steering wheel option is available. Komatsu has extended the service intervals for the engine oil and filter. New anchor point tie-offs make maintaining and cleaning the machines safer for operators.
"In designing the WA475-11 and WA485-11, we focused on what truly matters to our contractors based on years of direct feedback — efficiency, power, safety, and operator comfort. These wheel loaders build on proven performance of previous models with innovative advancements designed to enhance productivity," said Bruce Boebel, director of products and service at Komatsu. "We're excited to introduce these machines and put them to use for our aggregate contractors and beyond."
