The Cat® 798 AC electric drive truck is designed to haul more \u2014 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.

CAT BODIES
- Greater visibility thanks to wide field of view from the cab and radial retard grid that improves right-hand view.
- Safer access and egress with 600-mm-wide (23.6-in-wide) ladders, flat deck, toe kicks, and optional power access stair attachment.
- Confidence-building features such as anti-rollback, traction controls, reverse shift inhibitor, Automatic Retarding Control, and door sensor warning for park brake application.
- Full dynamic retarding through a compact radial grid, backstopped by the proven design of Caterpillar four-corner oil-cooled brakes, for stable handling and confident stopping.
- Fully independent secondary brake system that provides emergency controllability with a hydraulically actuated secondary brake pedal that serves as a backup to electronic controls.
- The most efficient electric drive truck in its size class — moving more tonnes per liter (tons per gallon) and hauling more material faster—so you can move more over the course of a shift, or haul the same amount of material with fewer trucks.
- Available with higher horsepower to boost productivity in deeper pits, plus electronically-selectable lower horsepower settings that allow the 798 to better align with mixed fleets.
- Ease of operation and reduced costs thanks to deep integration of Cat engine, AC drive system, hydraulics and controls.
- End-to-end visibility of all truck parameters for optimized fuel efficiency, speed on grade and parasitic loads across the operating range.
- Excellent slow speed control within service areas as well as superior motor torque and acceleration pulling away from the shovel.
- Ergonomic cab layout, excellent all-around visibility, and controls, levers and switches that are positioned for ease of use.
- Automatic climate control and reduced vibration and sound.
- Next generation seat with height adjuster, adjustable shoulder stock to keep the seatbelt from rubbing, and seat back, side and lumbar bolsters to increase stability.
- High displacement, low rpm rating and conservative horsepower ratings, which mean more time on the haul road and less time in the shop.
- Inlet manifolds and turbochargers that are located outside of the engine's V, giving the service technicians more space to work on top of the engine and within the engine bay.
- Sealed and pressurized inverter cabinet that requires no cleaning, eliminating hundreds of hours of maintenance over the life of the truck/
- Engine walkways and service platforms, modular components, service-friendly layout and ground-level grouped service points.
- Extended oil change interval (up to three times) with standard engine equipment including Centrifugal Oil Filter (COF) and Self-Cleaning Filter (SCF).
- First overhaul life of 25,000 hours for lower cost of ownership, with proven C175 engine and electric drive system.
- Highly validated and proven straight frame rail design that eliminates the bends and breaks that can occur at stress concentrations.
- Outstanding durability delivered by box section construction that uses Caterpillar proprietary steel specification for excellent welding characteristics.
- Increased frame life thanks to deep section main rails in critical areas of the frame lower stress levels.
- Frame, powertrain, engine and components that are built to be rebuilt — delivering multiple lives of like-new performance at a fraction-of-new price.
- High voltage system that operates at lower current than most competitive trucks, contributing to higher efficiency, lower heat generation, smaller and lighter components, and longer component life.
- Radial style retarding grid with AC electric motor that requires no regular motor maintenance and is quieter and lighter than box grids.
- State-of-the-art high voltage IGBTs for maximum AC drive system efficiency, and a dual-bearing brushless alternator that delivers long life and less maintenance, with no shimming required.
- AC Drive dynamic retarding for continuous retarding power; AC electric motor that reduces maintenance; and state-of-the-art high voltage IGBTs for maximum AC drive system efficiency.
- Variable hydraulic blower fan, which provides optimized cooling even at idle for increased component performance and life.
- Designed to use less fuel, which reduces engine emissions and carbon footprint.
- Optional U.S. EPA Tier 4 Final / EU Stage V engine, which reduces NOx by 62% and particulates by 93% when compared to Tier 1 emissions.
- Reduced waste thanks to Centrifugal Oil Filter (COF), standard self-cleaning engine filter, extended oil change intervals and reduced oil usage.
- Engines compatible with diesel fuel blended with lower-carbon intensity fuels such as biofuels and renewable fuels, plus power options like trolley.
- Cat Rebuild and Cat Reman programs, which preserve raw materials, conserve energy and reduce emissions.
- Equipped with standard Product Link™ Elite monitoring system, which delivers health and payload information to keep performance high and enable proactive maintenance planning.
- Factory-ready for fully integrated Cat MineStar™ Command for hauling, an autonomous hauling solution proven to increase productivity up to 30%.
- Optional MineStar Fleet, a fleet monitoring system, to measure, manage and maximize the overall hauling operation.
- Optional MineStar Detect proximity detection system, which uses cameras to give operators a better view of what's happening around their equipment.
- Optional in-cab Cat Driver Safety System (DSS) intervenes when operator fatigue or distraction are detected.
- Bodies designed to fit with the chassis, sized to meet payload requirements and work as part of the truck system.
- High Efficiency (HE) dump body option that is lightweight, simplified and durable.
- With unique minimal structure design, HE body provides long life while minimizing weight for increased payload.
- HE body sized and configured to meet the specific needs of the mine, dictated by fragmentation, abrasion, cohesion and the loading tool.
