773G Off-Highway Truck

773G Off-Highway Truck

The G Series represents a new era for Cat’s Off-Highway Trucks and the 773G provides our customers with a quality operating environment that enhances productivity and provides significant savings in fuel consumption, too. Ergonomically designed with an operator’s comfort in mind, the 773G has an updated cab with new comforts as well as controls conveniently placed within reach of the operator’s hands. Built with a Cat C27 diesel engine, this 60-ton payload uses increased torque delivering 5% additional horsepower. An ideal pass match for the 773G Off-Highway Truck is Cat’s 988K Wheel Loader, 990K Wheel Loader, or the 390F Hydraulic Excavator. Simply put, the 773G will make a positive difference in haul performance all day, every day for today and tomorrow’s work.
