CONSTANT POWER

Superior mechanical power density delivers high efficiency at the lowest system weight and cost.

The Cat seven-speed planetary power shift transmission varies gear ratios to optimize powertrain efficiency to the application, delivering constant power over a wide range of operating speeds.

The lock-up torque converter delivers low-speed movement control and unsurpassed stall torque while still allowing for efficient direct drive haulage. Cat final drives work as a system with the planetary power shift transmission to deliver maximum power to the ground.

FASTER SPEEDS

The 797F delivers optimal speed on steep grades, poor underfoot conditions and haul roads with high rolling resistance for faster cycle times when compared to competitive trucks. Its C175-20 diesel engine's 20-cylinder, four-stroke design uses long, effective power strokes for optimum efficiency.
—The 23% net torque rise provides unequaled lugging force during acceleration. The 797F travels loaded at a top speed of 60 km/h (42 mph).

SUPERIOR CONTROLLABILITY

Like all Cat mechanical-drive trucks, the 797F features four-corner oil-cooled brakes and Automatic Retarding Control to improve handling and machine control so operators can work quickly and confidently.

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 797F to use less fuel, which reduces engine emissions and carbon footprint, and there is zero fuel burn during retarding.
— The optional Tier 4 Final engine reduces NOx and particulate matter.
— Rear axle filtration, extended life filters and extended 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.

THE INDUSTRY'S BEST EMISSIONS SYSTEM

The Cat 797F is available in a fuel-efficient configuration that meets U.S. EPA Tier 4 Final emissions standards. Through over 150,000 hours of successful operation on Cat large mining trucks, the system has proven its ability to deliver with no impact on machine performance.

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.

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.

OVERALL LOWER COSTS

— Over 130,000 hours in Canadian Oil Sands
— 26% LOWER MAINTENANCE COSTS
— 20% LOWER OPERATING COSTS
— 36% LOWER OIL & LUBE COSTS
— UP TO 10% LOWER FUEL COSTS
​​​​​​​— Major drive train component life improvement
​​​​​​​— Over 80% of frame is cast, not fabricated
​​​​​​​— 5% tire life improvement
​​​​​​​​​​​​​​— Significant engine life increase

​​​​​​​

WHEN FUEL EFFICIENCY GOES UP, COSTS GO DOWN

Aside from paying operators, fuel is often the biggest operating expense for a mining truck. That's why we've worked to make the 797F one of the most fuel-efficient trucks in the industry. We've completed multiple projects in search of new ways to reduce fuel consumption in a variety of applications such as flat hauls, high-altitude deep pits and oil sands. And we've seen improvements from 3% to 10%.

Multiple power settings allow you to operate at full power or in economy mode, so you can decide how much power you need. By flipping a switch, these modes fine-tune hydraulic and engine output to match the job at hand. Eco-mode has been shown to deliver fuel savings of up to 3.5% per cycle.

OPTIMIZED PAYLOAD

The 797F features a robust frame that allows for maximum payloads so you can haul more with every load. In higher altitudes, you'll enjoy a cost per ton advantage over competitive models, ranging from 6% to as high as 14%. And when you choose the HP Body option, you'll reduce weight an additional 2.0-5.0 tonnes (2.2-5.5 tons).

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 797F 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.

Cat Truck Bodies

You have a choice of four MSD II (Mine Specific Design) bodies in conjunction with a configurable liner system to achieve the most efficient hauling solutions at the lowest-cost-per-unit-of-production.

Body Selection

The Cat truck body program is committed to providing you the most efficient and highest value body solution for your operation. By studying your mine site and understanding the overall operational requirements and constraints, the body can be configured to meet the unique needs of your application.

MSD II Body

The MSD II bodies are the number one choice in the mining industry. The internal body shells are designed and manufactured for superior impact and wear protection. Coupled with the Caterpillar mine specific design process the MSD II bodies optimize the balance of payload and durability.
