2025 Caterpillar Mining Trucks 794 AC

What will it take to boost your bottom line? The Cat® 794 AC electric-drive truck delivers a full 320-ton payload, increased speed on grade, 40% more retarding power than competitive trucks, superior braking performance and easier maintenance. The result? High availability, more confident operators and improved productivity. The 794 features a proven electric-drive powertrain that is Caterpillar designed, integrated and supported. Validated on sites around the world, the 794 has proven its performance in a variety of applications, making it the ideal choice for a wide variety of applications. It hauls more every load, every cycle and every shift. And it delivers a better bottom line to the most important mine in the world: yours.

UP TO 8% BETTER PAYLOAD

The 794 AC has a higher-rated field payload than competitive trucks thanks to lower empty weight and higher-rated GMW.

40% MORE RETARDING POWER

Thanks to its superior retarding power, 100% anytime braking and four-corner wet disc brakes, the 794 AC boosts operator confidence and goes faster longer.

UP TO 8% BETTER SPEED ON GRADE

The 794 AC achieves top speed of 60 kph / 37 mph and is capable of traveling at a maximum 28% grade loaded.

Features may include:

Safety
  • SAFETY-INFUSED
  • — Wide field of view for greater visibility
  • — Integrated ROPS and FOPS
  • — Door sensor warning for park brake application
  • — Wide ladders, flat deck, toe kicks
  • — Integrated emergency brakes
  • — Anti-rollback(reverse shiftinhibitor)
