772G Off-Highway Truck

Your long-term success is our goal here at Cat, so we’ve developed our 772G to be more productive and economical for our customers for years to come. Equipped with new transmission controls, the 772G is built for heavy-duty, off-road applications and delivers quick haul cycles with automotive-quality shifting and comfort. The 772G is also built with a Cat C18 diesel engine and with our fuel saving strategies, you can adjust engine power to meet your specific needs. Ideal pass match options for the 772G are the Cat 986K or the 988K Wheel Loader and the 390F L Hydraulic Excavator. When you consider its fuel efficiency and performance, the 772G is the right Off-Highway Truck for all generations.
