- Operator Work Area
Work Area View improves operator visibility to working environment around machine
— Integrated Object Detection System with Dedicated Dash Display
- Anti Rollback
Uses physical grade and payload to determine the rimpull needed to keep the truck stationary. As a truck coasts to a stop up a grade, it will automatically catch the truck with the service brakes if the operator does not press the brake pedal.
- Enhanced Traction Control
More Responsive Traction Control System: Reduces tire wear and Improves machine performance.
- PROVEN IN THE FIELD
Most popular 191-tonne (210-ton) truck in the mining industry
— 80% of the industry
— Delivering results for decades
— Easy to operate and maintain
- FAST SPEEDS
The 789 delivers a faster speed on grade than competitive trucks, reducing cycle times and lowering overall costs. — The 23% net torque rise provides unequaled lugging force during acceleration, on steep grades and in rough underfoot conditions. Torque rise effectively matches transmission shift points for maximum efficiency and fast cycle times.
— And expanded tire options allow mines to take advantage of higher speeds, particularly in flat long-haul high-speed applications.
- SUPERIOR CONTROLLABILITY
Like all Cat mechanical-drive trucks, the 789 features four-corner oil-cooled brakes and Automatic Retarding Control to improve handling and machine control so operators can work quickly and confidently.
- Machine Utilization
Improved operator comfort and easier machine control means higher utilization of machine capabilities over the shift.
- 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.
- 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 789 with a number of enhancements that lessen its impact on the environment. Features like oil renewal systems, continuous rear axle filtration, extended life filters and longer maintenance intervals decrease the amount of waste contributed to the environment.
We also continue to research alternative energy sources such as biofuels (B20) and a liquefied natural gas-supplied Dynamic Gas Blending solutions 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.
- EMISSIONS OPTIONS
This 789 is EPA Tier 4 / EU Stage V compliant and powered by the 2,100 HP Cat 3516E engine. This quad turbocharged diesel engine delivers high power and reliability in the world's most demanding mining applications. The engine is a 16-cylinder, four-stroke design that uses long, effective power strokes for more complete fuel combustion and optimum efficiency.
- Oil Renewal System
Optional oil renewal system extends engine oil change intervals from 500 hours to 4,000 hours or more to increase machine availability and reduce costs.
- Fuel Efficiency
The engine provides additional retarding by running against compression on downhill hauls. During retarding applications the engine ECM does not inject fuel into the cylinders for exceptional fuel economy.
- 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
Contradicting a common belief that bigger is better, the 789 has a weight advantage over larger trucks so you can haul more with every load.
— The 789 also delivers a 10-15% cost per ton advantage over competitive trucks, depending on application.
- A TRUCK YOU CAN DEPEND ON
The 789 has been a dependable performer on mine sites for decades, delivering high availability, reliability and reduced costs that come with long life — from the engine and powertrain to the components, brakes and frame.
— Component life is further enhanced thanks to the standard rear-axle continuous filtration feature, which operates when the engine is running.
— Cleaner oil helps promote longer lubrication that leads to longer life.
- double reduction final drives
Caterpillar final drives work as a system with the transmission for maximum power to the ground at the lowest cost.
- Product Link Elite comes standard
Product LinkTMElite is Caterpillar's next generation on-board hardware that enables your assets to collect and transmit information into locally-hosted or cloud-hosted applications. Its easy-to-configure interface and customizable data-push frequency enable equipment management anywhere, anytime.

- 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.
With the MineStar Detect proximity detection system, you can equip your 789 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.
- Road Analysis Control (RAC)
Optional system monitors haul road conditions by measuring frame rack and pitch to improve haul road maintenance, cycle times, tire life and fuel efficiency.
Truck Body Systems
- 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 exclusive 10/10/20 payload guidelines help achieve a balance of excellent payload with safe operation.
- HIGH PERFORMANCE BODY (HP)
A new lightweight design that provides durability along with a higher payload.
The HP body features robust top rail geometry with internal stiffeners and a high-visibility load placement indicator.
— Floating bolsters and spring plates improve overall durability by avoiding welds in high stress areas.
— In addition, the body requires only minimal liner coverage due to thicker and harder base plates.
— Curved front / side transitions minimize carryback.
- MINE SPECIFIC BODY (MSD II)
For mature mines with good operational and maintenance practices, the lighter weight MSD II body is available in several sizes. It is a customer / site specific body that is designed to maximize performance.
- DUAL SLOPE BODY
The original standard body, the Dual Slope body provides excellent load retention, maintains a low center of gravity with optimum load distribution, reduces shock loading and is available in lined and unlined configurations.
- Custom Body Options
A variety of options including tail extensions, sideboards, tumble bars, rock boxes and rock shedders are available to maintain rated payload, reduce spillage and improve hauling efficiencies.
