Caterpillar F-Series mining truck
F-Series mining trucks log more than 75,000 hours of field testing
By Kerry Clines
Caterpillar’s F-Series mechanical drive large mining trucks – the 793F (shown) and 797F – have accumulated more than 75,000 hours of field testing. In addition, Cat is also prototype testing the 795F AC electric drive truck, which will represent a new size class for Caterpillar.
The trucks feature the Cat C175 Tier 216-cylinder diesel engine, which Cat says offers longer life between rebuilds, lower sound levels, improved altitude capability, and improved fuel consumption compared to the 3500 Series engines it replaces.
The 793F boasts a faster speed on grade to deliver 5 to 10 percent more productivity than the 793D. The new cab features enhanced ergonomics and easy-to-access controls for improved operator comfort and increased efficiency.
The new class size of the 795F AC offers customers more options by filling the gap between Cat’s large and small haul trucks. Four-corner blended retarding allows safe, fast downhill speeds, increasing operator confidence and machine control. Ground-level access allows easier servicing and improved safety on the 797F. The truck’s increased horsepower provides a faster top speed to shorten cycle times and increase productivity. EW
