The 794 AC rigid-frame haul truck has a capacity of 320 tons. It uses a Cat C175-16 engine with a Cat AC power train. System power is adaptable to accommodate changes in production targets and to work seamlessly in mixed fleets where truck speed differences can reduce productivity. Three power options are available: 2750, 3100, and 3500 horsepower.
The Cat High Efficiency (HE) Body is sized and configured to meet the specific needs of the mine, dictated by fragmentation, abrasion, cohesion and the loading tool. The 794 AC body is integral to the truck and is sized to meet the payload requirements without compromising vehicle balance, braking or control.
The truck features four-corner wet disc brakes as well as dynamic braking and 5,480 horsepower of continuous retarding.
