Improvements for machine level access and egress include a standard 600 mm (24 in) diagonal stairway across the front of the machine. Improvements for ground level access include an optional powered access stairway.

Integral ROPS Cab

Resiliently mounted to the main frame to reduce vibration and sound, the integral ROPS structure is an extension of the truck frame and exceeds SAE requirements.

Isolation Box

Lockout tagout box mounted on front bumper includes engine shutdown switch, battery lockout, starter lockout and transmission lockout.

Cat Detect System

Knowing what's around your 793F at all times is important. The Cat Detect system is factory installed as standard equipment on 793F Mining Trucks. The full Cat Detect system, RADAR AND CAMERA, provides both audible and visual indications of detected objects. This system uses a combination of short and medium range radars which surround the machine, along with cameras on each side to allow the operator to confirm the detected object. The cameras supplement the radar alerts and are selectable by touch screen menus through an intuitive interface.

Other Safety Features

— Slip resistant surfaces
— 76 mm (3 in) wide orange three-point operator restraint
— Wide angle mirrors
— Body raised indicator
— Double body retaining cables
— Guard rails
— Reverse neutralizer when dumping
— Low interior sound level


The Cat 6-speed transmission, with the latest APECS controls, is paired with the C175-16 engine to deliver optimum power over a wide range of operating speeds.
— The lock-up torque converter engages at approximately 8 km/h (5 mph), delivering unsurpassed stall torque for its size class.
— Cat final drives work as a system with the upper powertrain to deliver maximum power to the ground.


The 793F is 6% faster than competitive trucks and delivers optimal speed on steep grades, poor underfoot conditions and haul roads with high rolling resistance. Its C175-16 diesel engine's 16-cylinder, four-stroke design uses long, effective power strokes for optimum efficiency.
—The 20% net torque rise provides unequaled lugging force during acceleration.

Torque rise effectively matches transmission shift points for maximum efficiency and fast cycle times.
— Travels at a class-leading speed of 12.9 kph / 8 mph on 10% grade
— Achieves top speed of 60 kph / 37 mph
— Capable of traveling at a maximum 28% grade loaded


Like all Cat mechanical-drive trucks, the 793F features four-corner oil-cooled brakes and Automatic Retarding Control to improve handling and machine control so operators can work quickly and confidently.


Fully integrated AHS factory offering:
— 240+ autonomous trucks in service
— Over 1.6 billion tonnes hauled
— Near continuous utilization


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.


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.


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.


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 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.


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.


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).


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)

Cat® MineStar™ Solutions

Whether you want to address a single challenge or make step changes in the overall safety, efficiency and productivity of your surface operation, Cat® MineStar™ has a solution for you. MineStar is the mining industry's most comprehensive and thoroughly integrated suite of technology offerings.


Cat Fleet helps you identify opportunities to improve truck efficiency in ways that reduce costs, boost productivity and add real value to your bottom line.
— Eliminate Queuing
— Optimize Shift Changes
— Reduce Fuel Stops


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 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.


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.
