770G Off-Highway Truck
In 1963 Caterpillar introduced the 769, a revolutionary off-road truck that was purpose-built for the rigors of mining and heavy construction. Fifty years later, our trucks have never been better. We’ve taken the best of our rugged, dependable heritage and combined it with technologies that help our environment, make your operators more productive, and dramatically improve the economics of your haul fleet. The 770G has an updated Traction Control System (TCS) to keep you moving even when the ground conditions aren’t perfect. You’ll see improvements in fuel use through new and flexible fuel savings and we’re making the operating experience best in class with automotive quality shifting, noise reduction, and cab updates. Our heritage and new use of technology are combined in this truck for one purpose – the continued success of your business.
