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 789D delivers a faster speed on grade than competitive trucks, reducing cycle times and lowering overall costs. The 3500 series engines are 16-cylinder, four-stroke designs that use long, effective power strokes for more complete fuel combustion and optimum efficiency.
— 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 789D features four-corner oil-cooled brakes and Automatic Retarding Control to improve handling and machine control so operators can work quickly and confidently.

Power to the ground

The Cat mechanical drive power train and power shift transmission provides unmatched operating efficiency and control on steep grades, in poor underfoot conditions, and on haul roads with high rolling resistance.

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 789D 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

The 789D comes with two engine options: the Cat 3516B and 3516C EUI. Both of these quad turbocharged diesel engines deliver high power and reliability in the world's most demanding mining applications. The engines are 16-cylinder, four-stroke designs that use 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 789D has a weight advantage over larger trucks so you can haul more with every load.
—The 789D also delivers a 10-15% cost per ton advantage over competitive trucks, depending on application.

A TRUCK YOU CAN DEPEND ON

The 789D 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.

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 789D 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.

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

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.

GATELESS COAL BODY

This specialized high-volume body, available in several sizes, is targeted at dedicated coal haulage applications with minimal impact.

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.
