The Cat® 798 AC electric drive truck is designed to haul more ore — with more speed, more stability and more reliability than any other electric drive truck in the marketplace. And while it may be the newest addition to the Cat ultra-class lineup, it delivers the same powerful, proven performance you expect from a Cat truck. The 798 delivers a full 372-tonne (410-ton) payload, increased speed on grade, more retarding power than competitive trucks, superior brake performance and easier maintenance. The result? High availability, more confident operators and improved productivity.
