BUMPER-TO-BUMPER CATERPILLAR
The individual components, software, systems and engine that go inside a Cat truck have different purposes, but they have one very important thing in common: They are all manufactured by Caterpillar and supported by the Cat dealer network.
This integration ensures that the entire truck — from body to bumper, engine to electronics — can be fully optimized to deliver the lowest cost per ton.
ONLY SINGLE-SOURCE ELECTRIC DRIVE TRUCK IN ITS SIZE CLASS
The Cat engine, AC drive system, hydraulics and controls have been integrated to make the 798 easy to operate, providing excellent slow speed control within the service areas and superior throttle response on acceleration to move out of the loading or dump areas. Integration of the engine and powertrain delivers low operating costs through electronically combined powertrain components.
— 100% designed, validated and built by Caterpillar
— Full support of Cat dealer and parts network
YOUR PARTNER FOR THE COMPLETE
EQUIPMENT LIFECYCLE
No one knows more about how to get the most from a piece of Cat equipment than your local Cat dealer. This one-of-a-kind, on-the-ground support network delivers expert service, integrated solutions, after-sales support, fast and efficient parts fulfilment, world-class rebuild and remanufacturing capabilities, and more.
Cat dealers operate as nearly 200 local businesses — each one fully embedded in and committed to the geographic area it serves. That means you work with people you know, who know your business, and who respond on your timeframe.
MINING — FOR A — BETTER WORLD
Governments and regulatory agencies mandate that you establish and follow environmentally sound policies and practices as you meet the demand for mined materials. We're focused on doing our part to make sure our trucks help you meet those regulations.
REDUCING EMISSIONS
We’ve designed the 798 AC to use less fuel, which reduces engine emissions and carbon footprint. The optional U.S. EPA Tier 4 Final / EU Stage V engine goes even further, reducing NOx by 62% and particulates by 93% — when compared to Tier 1 emissions.
In addition, a centrifugal oil filter and self-cleaning filter are standard on all engines, extending oil change intervals and reducing oil usage.
We also continue to research alternative energy sources such as biofuels and liquefied natural gas (LNG), and power options like electrification and trolley to find new ways to reduce emissions. In addition, we preserve raw materials, conserve energy and reduce emissions through the Cat Reman program, which returns end-of-life components to like-new condition.
EFFICIENCY
The Cat AC drive is a high voltage system (2,600 volts) that operates at lower current than most competitive trucks. When combined with Cat's total integration and design of the truck and drive system, the result is higher efficiency, lower heat generation, smaller and lighter components, and longer component life.
—The Enhanced Engine Oil Filtration (EEOF) package, eliminates the need for an engine oil filter change and reduces oil usages.
Engines with Advanced Technology
Engines with advanced technology contribute to better fuel economy and decreased emissions.
BUILT TO BE REBUILT
Cat trucks are designed to last over 100,000 hours, and many are going well beyond that. The frame, powertrain, engine and components are built to be rebuilt — using new, remanufactured or rebuilt parts and components — so you can take advantage of multiple lives of like-new performance at a fraction-of-new price.
OPTIMIZED PAYLOAD
The 798 AC delivers a true 372-tonne (410-ton) payload. Thanks to an efficient design, the class-leading payload is achieved regardless of local attachments.
The 798 AC is powered by the C175-16 engine, which is available with two horsepower options and can be configured for U.S. EPA Tier 4 Final / EU Stage V regulations.
— Robust design delivers long life and the option to rebuild.
— Designed for easy serviceability with readily accessible components, the modular aftertreatment system reduces overall fluid and fuel consumption and is aligned with truck preventive maintenance intervals to maintain high availability.
— Lower fuel burn results in longer engine life and lower repair costs.
EFFICIENT HAULING
The 798 AC is the most efficient electric drive truck in its size class. It moves more tonnes per liter (tons per gallon) and hauls more material faster — so you can move more over the course of a shift, or haul the same amount of material with fewer trucks.

COMMAND FOR HAULING
This autonomous hauling solution helps improve productivity, efficiency and profitability while reducing overall costs.
What if your trucks could respond to calls to the shovel, move into position, haul to dump points and even report for maintenance — all without an operator on board? That's what Cat Command for hauling enables.
But this autonomous Cat MineStar solution is more than just an operator-free system. It takes advantage of the most sophisticated technologies available to deliver a next-generation haulage solution — one that boosts safety, productivity and availability on busy mine sites, especially those in difficult or remote locations. With autonomous hauling, the future is here — and we're there to help you bring it to your operation.
DETECT
With the MineStar Detect proximity detection system, you can equip your 798 with cameras to give your operators a better view of what's happening around their equipment — or combine cameras and radar into a true object detection system that automatically alerts operators to hazards.
You can even add satellite capabilities to provide proximity warnings and avoidance zones, seat-belt monitoring that encourages operators to buckle up, and in-cab systems that intervene when they detect fatigue or distraction.
GET THE RIGHT BODY FOR THE JOB
When it comes to truck bodies, one size does not fit all. And when it comes to your Cat truck, Cat bodies are the best choice. We follow a dynamic approach to engineering — treating the body as part of a system rather than a static structure. Cat bodies are designed to be an integral part of the entire vehicle system, ensuring you achieve maximum chassis life.
— They're sized to meet payload requirements without compromise to vehicle balance, braking or control.
— From the design to the materials, manufacturing to shipping, the entire process meets Cat standards of quality and control.
— The Caterpillar 10/10/20 payload guidelines help achieve a balance of excellent payload with safe operation.
Integrated Body and Chassis Design
Integral to the truck the body is designed to fit with the chassis and work as part of the truck system. Each body is sized to meet the payload requirements without compromise to vehicle balance, braking or control.
High Efficiency (HE) Body
The body is sized and configured to meet the specific needs dictated by fragmentation, abrasion, cohesion, and the loading tool to maximize the payload capability of the truck.
- Curved floor, front, and canopy strengthens entire body as a structure.
- Strength of base plates allows minimal wear package and low operating weight.
- Joint isolation system reinforces welded areas and exploits high strength main plates.
- Runners transfer weight to the truck frame.
