Sound Standards (1)
The operator sound pressure level measured according to work cycle procedures specified in ISO 6394 and 6396 is 74 dB(A) for cab offered by Caterpillar, when properly installed and maintained and tested with doors and windows closed.
Sound Standards (2)
Hearing protection may be needed when operating with an open operator station and cab (when not properly maintained or doors/windows open) for extended periods or in a noisy environment.


Meets U.S. EPA Tier 4 Final emission standards, and features the Caterpillar Selective Catalytic Reduction (SCR) system that provides the least Total Fluid Consumption cost with greater reliability.

High Performance Engine

High Performance Engine

The Cat® C175-16 engine offers you the perfect balance between power, robust design and economy.

  • The C175-16 is a 16-cylinder, four-stroke design that uses long, effective power strokes for optimum efficiency.
  • Is compliant with U.S. Environmental Protection Agency emission requirements.
  • The 20 percent net torque rise of the C175-16 provides unequalled 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.
  • High displacement, low rpm rating and conservative horsepower ratings mean more time on the haul roads and less time in the shop.
  • The Cat Common Rail Fuel System is an electronically-controlled system senses operating conditions and regulates fuel delivery for optimum fuel efficiency. This precise and flexible fuel system gives the engine the ability to meet emission regulations without sacrificing performance, reliability or durability.
  • The flexible core design of the MESABI radiator means easier serviceability along with long life and high durability.
  • You have two starter options: The tank on the standard air start system is ground level serviceable, while the electric start option allows the air system to be totally removed from the truck.
  • Enhanced Engine Oil Filtration System (SCF/COF): reduces risk of contamination, extends oil change intervals & reduces oil waste, and eliminates cartridge filter changes

Enhanced Serviceability

Servicing Ease

Improved serviceability points and grouped service locations mean your truck spends more time on the haul road than in the shop.

In-Frame Access

Easy access to daily service points simplifies servicing and reduces your time spent on regular maintenance procedures. Enhanced serviceability and long service intervals are designed to increase machine availability and productivity.

Ground Level Access

Gives you easy access to major components for easy servicing and removal.


Automatic lubrication system reduces your maintenance time by automatically lubricating necessary components on a regular basis.

Scheduled Oil Sampling

S·O·S SM sampling valves speed sampling and analysis reliability.

Pressure Test Points

Disconnect valves are conveniently located throughout the hydraulic systems for easy pressure testing.

Sealed Electrical Connectors

Electrical connectors are sealed to lock out dust and moisture. Harnesses are braided for protection. Wires are color-coded for easy diagnosis and repair.

Oil Change Intervals

Extended oil change intervals reduce oil waste.

Robust Braking

Cat oil-cooled, multiple disc brakes on all four corners offer you exceptional, fade-resistant braking.

Power Shift Transmission

A smooth shifting six speed transmission using ECPC gives operators a comfortable ride, constant power and improved fuel efficiency.

2 – Lock-Up Torque Converter,
3 – Final Drives

Reliable Mechanical Drive System

The 793F's power train gives you the fastest truck on steep grades, poor underfoot conditions and on haul roads with high rolling resistance.

Comfortable Cab

Operators find the large, spacious cab offers unmatched visibility and exceptional comfort.

Truck Body Systems

Truck Body Systems

You have four body options with the 793F: X Body, MSD II (Mine Specific Design),Gateless Coal Body and High Performance Body. These bodies are specifically designed to work with the Cat frame for superior structural performance.

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. The HP body features a lightweight, simplified and durable design that provides complete front machine coverage and extended overhead protection.
