The new Cat trucks offer innovative designs for improved safety and performance. “All of the F-Series mining trucks incorporate innovative design and engineering that enables them to deliver lowest cost per ton,” said Ed McCord, mining truck product manager. “With the latest technology in AC electric drives now available, Caterpillar is able to offer both types of drive to the mining industry. We see the addition of electric mining trucks as a complement to our mechanical drive trucks.”

The most evident new component is the Cat C175 diesel engine, which is the power plant for each of the new trucks. The C175 meets US EPA Tier 2 emissions standards, yet it delivers 4,000 horsepower (2 983 kW) in the 20-cylnder version that powers the 400-ton (345-tonne) capacity 797B. The 16-cylinder C175 powers the 795F AC with 3,400 horsepower, and it powers the 793F, which has 250 tons (227 tonnes) capacity, with 2,650 horsepower (1 976 kW). 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. As a brand new platform, the 795F AC incorporates new technologies throughout. For example, four-corner blended braking and retarding—using Cat oil immersed and cooled disc brakes as well as electrical retarding—enhances safety and operator confidence.
