WA475-10 Wheel Loaders

The newly designed WA475-10 features next-generation technology developed with input from customers like you to deliver improved productivity and lower fuel costs. Ideal for quarry applications, this gentle giant is a unique solution for tomorrow’s challenges.

The WA475-10 saves 30% more on fuel efficiency than the previous model and is perfect for any hauling or loading jobs with an outstanding combination of fuel efficiency, productivity and ease of operation.
The wheel loader features the newly developed Komatsu’s Hydraulic Mechanical Transmission (KHMT), an innovative solution that makes the loader more powerful and more fuel-efficient. Variable speed control allows operators to adjust the machine’s top speed to meet specific site requirements, and the adjustable variable traction control also limits wheel spin on unstable and slippery ground conditions often found on many quarry and waste sites.
An optimised Z-bar linkage system provides much more lift force and a higher tonnes-per-hour production rate on the WA475-10, and the response time of the hydraulics and the dumping or lifting can be set to specific site requirements.

The loader can also be tailored for specific applications, whether that is the demanding nature of a waste site, or the abrasive environments of quarries. The Komatsu team will work with customers to provide a solution that is tailored to the loader’s application, from enquiry to post delivery, maintaining service checks and requirements.
