Caterpillar 793F rigid-frame haul truckThe new Cat C175 engine powering the 250-ton-capacity 793F mechanical-drive mining truck has racked up 130,000 hours of field testing in mining trucks and more than 120,000 hours in power systems. The new 793F is targeted to go into full production in fall 2009, with other mining trucks in the new F Series to follow. The 16-cylinder version of the 175 delivers 2,650 horsepower in the 793F. Cat says the C175 “promises longer life between rebuilds, lower sound levels, improved altitude capability and improved fuel consumption compared to the 3500 Series engines it replaces.” The F Series will usher in the first Cat electric-drive mining trucks, making Cat the only manufacturer of 200-ton and larger mining trucks with both mechanical and electric drive systems.
