First as the 797, then as the 797B, the design of the largest Cat mining truck has proven its productivity, durability and low cost of operation through more than 10 years of service in the world’s most challenging mining operations. Now, the 797F, with 4,000-horsepower (2983 kW) and rated payload capacities to 400 tons (363 tonnes), combines the strengths of its predecessors with a new engine, redesigned operator station and custom body systems to deliver even lower costs per ton—with less environmental impact.

Caterpillar is moving rapidly forward with the new large mining trucks showcased at MINExpo last year and representing the company’s largest investment ever in new mining technology. The Cat® 793F and 797F mechanical drive trucks and the 795F AC electric drive truck are all achieving milestones.

The 793F and the 797F have accumulated more than 75,000 hours of field testing and have proven their performance capabilities and their durability. The new Cat C175 engine that powers them has racked up 130,000 hours of field testing in mining trucks and more than 120,000 hours in power systems. Because of the success of these field-follow programs, the 793F is targeted to go into full production within a few months and the 797F late this year.
