775G Off-Highway Truck

Having a solid track record in the quarry and aggregates industry, Cat’s 775G has been designed and manufactured using the latest quality control technologies—both virtually and hands on—to ensure your Off-Highway Truck is ready to do work. Built with a Cat C27 diesel engine, the 775G has improved fuel efficiency and delivers an additional 5% horsepower. Our 775G is a great pass match for the Cat 988K or 990K Wheel Loader, too. By having the Cat G Series trucks in your haul fleets, you can be more productive, spend less time on maintenance, and support the environment with new levels of eco performance. Which ultimately allows you to make a positive impact within your business and community every day.
