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.

Sustainability

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 793F 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 793F 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.

Operating Cost

OPTIMIZED PAYLOAD
An empty weight advantage of at least 9 tonnes (10 tons) over competitive electric-drive trucks in its size class ensures you're getting the full payload you expect.
— And when you choose the HP Body option, you'll reduce weight an additional 2.0-5.0 tonnes (2.2-5.5 tons).

OVER 5% WEIGHT ADVANTAGE
Highest payload for rated gross machine weight (240-250 tons / 218-227 tonnes)
— HP Body option reduces weight more than 3 tonnes (3.3 tons)

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 793F 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.

1 - X Body
If you have a new mine or are a contract miner the X Body is designed for you. It uses the Cat Mine Specific Design process to create a body that is properly sized and configured to meet the specific requirements of heavy-duty applications.
— The X Body design offers a larger volume with no weight penalty.

2 - MSD II
The MSD II bodies are intended for established mines and are customized to suit your specific mining applications based on a mine site evaluation.
— The MSD II is the best lightweight body ever built for mining applications and achieves excellent payload performance.

3 - Gateless Coal Body
The Gateless Coal Body is intended for dedicated coal haulage applications. It can be loaded to achieve target payload across the full range of coal densities.
— The body is designed and built using the MSD II Body concept, ensuring superior durability and reliability.

4 - High Performance Body
When you equip your truck with a Cat High Performance (HP) body, you’ll experience the benefits of a higher payload thanks to a weight reduction of 2.0-5.0 tonnes (2.2-5.5 tons) or more.
