Overview

HIGHER PAYLOAD. BETTER GRADEABILITY. SUPERIOR SERVICEABILITY.

The Cat® 798 AC electric drive truck is designed to haul more — with more efficiency, controllability, and reliability than any other electric drive truck in the marketplace. And while it may be a recent addition to the Cat ultra-class lineup, it delivers the same powerful, proven performance you expect from a Cat truck. The 798 AC delivers a payload up to 372 tonnes (410 tons), high speed on grade, easier maintenance, and excellent electric retarding and brake performance. The result? Improved productivity, high availability, and more confident operators.

Benefits

CLASS LEADING 410 TON NOMINAL RATED PAYLOAD

Delivering the highest standard payload available in its size class.

UP TO 18% INCREASED TORQUE ON DEMAND

With Cat® TorqueBoost technology maximum drivetrain capability is unlocked for working in the toughest conditions.

EASIER MAINTENANCE LESS OFTEN

Large walkways on both sides of the engine make maintenance easier and faster.
