SPECIFICATIONS
What makes the Cat® 797F Mining Truck the most productive 363-tonne (400-ton) truck in the market? Is it the best-in-class payload? Superior braking that leads to confident, productive operators? Or a tough, rugged frame that delivers performance and long life no matter the conditions? Today’s 797F delivers all of this—and more. It’s fast, fuel efficient and delivers class-leading productivity, making it the industry benchmark for lower cost per ton in its size class. It hauls more every load, every cycle and every shift. And it delivers a better bottom line to the most important mine in the world: yours.
