THE CAT® 798 AC ELECTRIC DRIVE HAUL TRUCK.

The Cat® 798 AC electric drive truck is designed to haul more — with better cost per tonne, reliability, and serviceability than any other electric drive truck in its size class.

 

 

The 798 AC hauls more — every load, every cycle, every shift.

With the highest standard payload available in its size class and Cat® TorqueBoost technology, the 798 AC mining truck can move 410 tons (372 tonnes) through some of the toughest conditions at your mine site. The efficient design adds strength where it counts to carry more payload without sacrificing durability for the long haul.  

Optimized horsepower makes it possible for the 798 AC to run in all areas of the mine with the same engine and drive system. And while it may be a recent addition to the Cat ultra-class lineup, it delivers the same proven performance you expect from a Cat truck. 

The 798 AC features a powertrain that is Caterpillar designed, integrated, and supported on sites around the world. It hauls more every load, every cycle, and every shift. And it delivers a better bottom line to the most important mine in the world: yours.

 

 

PARTNERS FOR THE LONG HAUL.

With the help of our customers and Cat dealer team, we put the 798 AC to the test  — working in some of the harshest conditions in the Canadian Oil Sands.

798 AC electric drive mining truck

HIGHER PAYLOAD

EFFICIENT HAULING

SUPERIOR SERVICEABILITY

INTEGRATED POWER

DESIGNED FOR CONTROL

HIGHER PAYLOAD. HIGHER PERFORMANCE. 

The 798 AC delivers a payload of 410 tons (372 tonnes) and high speed on grade with excellent electric retarding and brake performance. Available with two horsepower options, the 798 AC is powered by the C175-16 engine and can be configured for U.S. EPA Tier 4 Final / EU Stage V regulations. While higher horsepower is available to boost productivity in deeper pits, an easy adjustment to a lower horsepower allows the 798 AC to better align with mixed fleets and keep fuel costs lower. The 798 AC can also be configured for high altitudes.

[+] Delivering the highest standard payload available in its size class.

[+] Designed for performance and long life.

EFFICIENT HAULING. FASTER ON GRADE.

The Cat 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. 

[+] Efficient design delivers higher payload

[+] Optimized drive system integration puts more power to the ground

SUPERIOR SERVICEABILITY. LOWER MAINTENANCE COSTS.

The 798 AC was designed to reduce the time you spend on regular maintenance procedures. The standard Product Link™ Elite monitoring system delivers critical health and payload information in real-time, keeping performance at optimum levels and allowing advanced troubleshooting and planning to lower maintenance costs.

[+] Enhanced serviceability and long service intervals help increase machine availability and productivity.

[+] Built to Be Rebuilt: A target first overhaul life of 25,000 hours contributes to a lower overall cost of ownership.

INTEGRATED POWER. higher torque.

Deep integration of the Cat engine, AC drive system, hydraulics and machine controls helps the 798 AC deliver low operating costs. End-to-end visibility of all truck parameters enables Caterpillar to optimize fuel efficiency, speed on grade and parasitic loads across the operating range. This high level of integration also delivers excellent slow speed control within service areas as well as superior motor torque and acceleration pulling away from the shovel.  

[+] Up to 18% More Torque

[+] Cat TorqueBoost technology unlocks maximum drivetrain capability for working in the toughest conditions

DESIGNED FOR CONTROL. PROVEN IN THE FIELD. 

Proven Cat braking systems deliver superior control so your operators can focus on productivity. The 798 AC features full dynamic retarding through a compact radial grid and is backstopped by the proven design of Caterpillar four-corner oil-cooled brakes. The result is stable handling and confident stopping.

[+] Strong dynamic retarding and robust design empowers operator to use oil-cooled brakes regardless of speed or payload

[+] Field validation: 85,000+ hours | Highest-hour 798 AC: 19,000+ hours | Electric drive system: 7M+ hours


 

 

EASIER MAINTENANCE, LESS OFTEN

+ First overhaul life of 25,000 hours drives lower cost of ownership

+ Engine and dual bearing drive alternator can be serviced separately, eliminating shimming

+ Modular wheel motors and final drives enable service on individual components

+ Sealed and pressurized inverter cabinet requires no cleaning, eliminating recurring maintenance

+ Long-life radial grid with AC motor control and serviceable elements

A PROVEN DESIGN PHILOSOPHY

When it comes to making Cat large mining trucks, we follow a proven design philosophy that focuses around five main areas:

1. MAKING A SUSTAINED INVESTMENT IN RESEARCH & DEVELOPMENT

2. INTEGRATING EVERY COMPONENT

3. DELIVERING IRON THAT PERFORMS

4. SUPPORTING PRODUCTS — AND PRODUCTIVITY

5. LISTENING TO OUR CUSTOMERS TO SPUR CONTINUOUS IMPROVEMENT


By following this philosophy — for every truck, every time — we 
ensure that you get what you expect from Caterpillar: the lowest cost per ton of any mining truck in the industry.

What's Your Goal?

Decrease Carbon

INCREASE PRODUCTIVITY

REDUCE CRITERIA POLLUTANTS

REDUCE LIFECYCLE WASTE

WHAT'S YOUR GOAL?

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.

Caterpillar offers environmental technologies and solutions for your Cat 798 AC to reduce emissions intensity and decrease carbon.

[+] Reduce Emissions Intensity (t CO2 / tonne moved)

[+] Reduce Criteria Pollutants (NOX & Particulates)

[+] Reduce Lifecycle Waste

REDUCE EMISSIONS INTENSITY: DECREASE CARBON

Caterpillar offers the following environmental technologies and solutions for your Cat 798 AC to reduce emissions intensity and decrease carbon.

[+] Cat Trolley Assist

REDUCE EMISSIONS INTENSITY: INCREASE PRODUCTIVITY

The 798 AC is factory-ready for MineStar Command for hauling, an autonomous hauling solution. Command enables near continuous utilization and has proven to increase productivity by more than 30%. Beside autonomous hauling, there are many other ways to increase productivity, using less fuel.

[+] Cat MineStar Command

[+] Scale & Production Studies

[+] Site Assessment

[+] Payload Optimization

REDUCE CRITERIA POLLUTANTS (NOx & PARTICULATES)

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.

[+] U.S. EPA Tier 4 Final (and Carb) Engine

[+] EU Stage V Engine

[+] China Nonroad Stage III Engine

REDUCE LIFECYCLE WASTE 

A centrifugal oil filter and self-cleaning filter are standard on all engines — extending oil change intervals and reducing oil usage. 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.

Cat trucks are designed to last over 100,000 hours, with many going well beyond. 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 likenew performance at a fraction-of-new price.
