  • A true 297-tonne capacity
  • Reliability and uptime
  • Easy serviceability
  • Low owning and operating cost
  • Operator confidence with four corner wet disc blended service brakes and traction control.

  • The 794 AC delivers across all aspects of performance, from 8% extra speed on grade and 34% more retarding power than comparatively-sized trucks to best-in-class braking performance and easier maintenance, delivering more power with lower costs. But there’s more to the new Cat 794 AC than performance alone — with all components manufactured by Cat, you get a fully integrated off-highway truck optimisable to the requirements of your site and business that delivers the most competitive cost per tonne. And with a speed advantage that empowers you to move more material with fewer trucks or per shift, the Cat 794 AC mining truck further delivers a market-leading performance that ultimately enables a more competitive business offering. 

    Infused with safety features that prioritise the safety, comfort and wellbeing of your operators and team, the Cat 794 boasts innovations such as stored energy dissipation at shutdown, integrated ROPS and FOPS, traction controls, anti-rollback (reverse shift inhibitor) and a wide field of view for greater visibility and safety. Additionally, this off-highway truck from Cat features ground-level system lockout, engine lockout and propulsion lockout to allow your maintenance crew to perform repairs safely and quickly.
