Komatsu Wheel Loaders WA270-7
WA270-7 Wheel Loader
The Komatsu Tier 4 interim technology on the WA270-7 is designed to keep the operator working rather than having to stop and regenerate while saving up to 10% on fuel burned. The hydrostatic drive system on the WA270-7 gives the operator quick and powerful response, self-braking effect of dynamic braking and traction control. A multi-function mono-lever, rearview camera system with separate screen and heated, air ride suspension seat give the operator a comfortable and ergonomic work environment.
