PRODUCTIVITY

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.
The 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.
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 High Performance (HP) body option, you’ll reduce weight an additional 2.0-5.0 tonnes (2.2-5.5 tons).
The Cat six-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.

SAFETY

Machine-level access and egress is enhanced with slip-resistant surfaces, guard rails, and a standard 600 mm (24 m) diagonal stairway across the front of the machine. An optional powered access stairway is available.
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.
A lockout/tagout box mounted on the front bumper includes engine shutdown switch, battery lockout, starter lockout and transmission lockout.
The standard Cat MineStar™ Detect Object Detection system combines radar and camera systems to warn operators about hazards within the immediate vicinity, while the optional Detect Driver Safety System alerts the operator if fatigue or distraction are detected.
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. With retarding power applied to all four corners, the full weight of the truck can be applied for traction, resulting in better control, more operator confidence and typically higher speeds in poor underfoot conditions.

OPERATOR COMFORT

With multiple cab options, the 793F can be equipped with the desired features for your operation.
All options offer an ergonomic layout, excellent all-around visibility, and controls, levers and switches that are positioned for ease of use.
The cab includes dozens of features designed to enhance comfort, such as automatic climate control and sound suppression.
The next generation seat includes a height adjuster; adjustable shoulder stock to keep seatbelt from rubbing on the operator’s neck; and seat back, side and lumbar bolsters to increase stability.

SERVICEABILITY

Time spent on regular maintenance procedures is reduced thanks to features such as extended service intervals; grouped ground-level maintenance and checkpoints; easy access to major components; the standard AutoLube system; sealed electrical connectors; oil level sight gauges and front wheel sight glass; and service platforms on the engine and transmission.
An optional 100% airless electric start option eliminates air system maintenance from the machine and improves uptime.
The Cat Enhanced Engine Oil Filtration System increases engine life, eliminates cartridge filter changes and makes it possible to extend oil change intervals.
The 793F can be equipped with an optional fast-fill service center with Live S•O•S℠ Service Center and brake wear indicators.
New and updated machines have extended oil and filter change intervals across the majority of compartments.

DURABILITY AND LONG LIFE

The 793F has been improved with longer-life components, extended service intervals and easier maintenance to deliver mechanical availability that is consistently greater than 90%.
The 793F is built on our most durable 231-tonne (255-ton) frame ever built, backed by unprecedented levels of virtual and in-iron validation.
A mild steel frame provides flexibility, durability and resistance to impact loads. Castings are used in high-stress areas and the integral 4-post ROPS cab provides increased strength.
Component life is enhanced thanks to the standard rear-axle continuous filtration feature. Cleaner oil helps promote longer lubrication that leads to longer life.
The frame, powertrain, engine and components are built to be rebuilt — delivering multiple lives of like-new performance at a fraction-of-new price.

CAT BODIES

Cat bodies are the best choice for the 793F. They’re designed to be an integral part of the entire machine system, ensuring you achieve maximum chassis life.
The High Performance (HP) body features a lightweight, simplified and durable design that provides complete front machine coverage and extended overhead protection.
The X Body 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.
Lightweight MSD II bodies are intended for established mines and are customized to suit your specific mining applications.
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.

SUSTAINABILITY

The 793F is designed to use less fuel, which reduces engine emissions, and there is zero fuel burn during retarding. The optional Tier 4 Final engine reduces NOx and particulate matter.
Features like rear axle filtration, extended life filters and longer maintenance intervals decrease the amount of waste contributed to the environment.
The Cat Common Rail Fuel System provides optimal fuel delivery, which reduces both fuel consumption and emissions output.
The 793F engine is compatible with diesel fuel blended with lower-carbon intensity fuels such as biofuels and renewable fuels.
By rebuilding machines and components, the Cat Rebuild and Cat Reman programs preserve raw materials, conserve energy and reduce emissions.
