ABOUT THE 770

Cat’s 770 40-ton payload sets the standard for haul performance in construction and quarry industries. We’ve taken the best of our rugged, dependable Off-Highway Truck lineup and integrated it with technologies that help our environment, make operators more productive, and dramatically improve the economics of haul fleets. An optimal pass match for the 770 is the Cat 986, 987, or 988 Wheel Loader or the 374 Hydraulic Excavators. No matter your business type, the 770 is designed to help you move materials safely and efficiently through every haul.
