Caterpillar is pleased to introduce to you the 773

The 773 has been designed and manufactured using the latest quality control technologies – virtual and hands on. This product has over 30,000 hours of proven performance in the hands of customers prior to production, all of which ensures the truck delivered to your yard is ready to work, reliably and dependably.
In addition to quality, Cat 773 Series trucks will lower your costs with seven different ways to help you conserve fuel. We offer you two customizable fuel economy modes that will let you choose your level of savings. With Cat 773 trucks in your haul fleet, you can be more productive, spend less time on maintenance, and support the environment with new levels of eco performance. Your crew will appreciate all the new comfort and conveniences in our updated cab. Simply put, Cat 773 trucks can and will make a positive difference to both your business and people – all day, every day.
The 773 Off-Highway Trucks represent a new era for Cat’s Off-Highway Trucks and the 773 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 773 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 773 Off-Highway Truck is Cat’s 988K Wheel Loader, 990K Wheel Loader, or the 390F Hydraulic Excavator. Simply put, the 773 will make a positive difference in haul performance all day, every day for today and tomorrow’s work.
