Feature and benefits

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.

Cost per ton advantage over competitive models in higher altitudes, ranging from 6% to as high as 14%, plus HP Body option reduces weight an additional 2.0-5.0 tonnes (2.2-5.5 tons).
Optimal speed on steep grades, poor underfoot conditions and haul roads with high rolling resistance for faster cycle times when compared to competitive trucks; travels loaded at a top speed of 60 km/h (42 mph).
Unequaled lugging force during acceleration thanks to 23% net torque rise.
Constant power over a wide range of operating speeds thanks to Cat seven-speed planetary power shift transmission.
Low-speed movement control and unsurpassed stall torque delivered by lock-up torque converter.

Multiple power settings that allow you to operate at full power or in economy mode, so you can decide how much power you need.
Modes that fine-tune hydraulic and engine output to match the job at hand; Eco-mode shown to deliver fuel savings of up to 3.5% per cycle.
Optimized fuel calibrations available for Tier 4, high altitude and lesser regulated applications.
Engine ECM that does not inject fuel into the cylinders during retarding applications, for exceptional fuel economy — zero fuel burn during retarding.
Increased fuel efficiency with Tier 4 configuration.
