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 The 793D can be equipped with an engine that runs on using Cat® Dynamic Gas Blending™ (DGB). Consider the emission decrease of DGB one more reason to get your trucks equipped. 30% less fuel cost is a substantial improvement — to your waste and the environment.

We also continue to research alternative energy sources such as biofuels (B20) 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.

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 Intelligent Caterpillar designed machine monitoring system provides critical machine health and payload data in real-time to keep the 793D performing at top production levels.

EXTENDED WHEEL LIFE Developed for uphill hauling applications, this arrangement is designed to extend wheel life and hauling performance on long uphill hauls. Extended life wheel groups are built with larger, more durable components, including larger spindles, wider wheel bearing spacing, a larger braking surface, and extended life friction disc material for longer brake life and more time between overhauls.

OPTIMUM POWER The Cat 3516B High Displacement EUI engine delivers the power and reliability necessary to perform in the most demanding applications. Designed for efficient operation, the 3516B offers excellent fuel efficiency, lower emissions, reduced engine noise and lower operating costs.

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 793D 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) Dual-Slope Body The dual-slope body design with V-shaped floor provides excellent load retention, maintains a low center of gravity, reduces shock loading, and maintains optimum load distribution on steep inclines and in challenging haul road conditions.
  • Reinforced, rolled steel top rail increases body strength and protects the body from damage caused by the loading tool or falling material
  • 8 degree "V" reduces shock loading and centers the load.
  • 7.5 degree forward body slope and 16 degree ducktail slope helps retain loads on steep grades.
2) Flat Floor Body The flat floor design with slight incline delivers excellent payload capacity, high dump clearances and smooth, controlled dumping.
  • Flat floor design provides consistent wear characteristics on body tail.
  • 12 degree forward body slope provides good load retention on better maintained haul roads.
  • 400 Brinell steel on surfaces provides excellent wear.
3) Mine Specific Design (MSD II) Body The lightweight MSD II body is based on the flat floor design and is customized to maximize payload potential and minimize cost-per-ton. Each MSD II body design begins with a detailed mine site profile to develop a body suitable for a mine's individual needs.

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.

Body Liners A variety of liner options are available to save weight and extend the body system's life. Wear surfaces and liners are equipped to handle tough impact loads while resisting abrasion. Wear plates deliver long life in high wear areas. Modular liner plate packages:
  • Smooth plate
  • Rock box
  • Zipper grid
  • Mechanically Attached Wear Plate System (MAWPS)
Custom Body Options Tail extensions, sideboards, tumblebars, rock boxes and rock shedders are available to maintain rated payload, reduce spillage, and improve hauling efficiencies.
  • Sideboards are designed to maximize or attain gross machine weight.
  • Tail extensions are used to help retain the rear portion of the pile and limit load spillage on haul roads, extending tire life.
Serviceability

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

FastFill Service Center Optional service center reduces daily maintenance times with clustered fast fill connections for steering oil, transmission oil, engine oil and coolant.

Oil Renewal System (ORS) Optional on-board engine oil management system is designed to increase availability and productivity by extending oil change intervals and reduce oil disposal labor and costs. ORS meters and injects used engine oil from the crankcase into the engine's fuel return line. New oil is manually added as a part of daily maintenance.

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

Scheduled Oil Sampling S•O•S℠ sampling valves speed sampling and analysis reliability.

Sealed Electrical Connectors Electrical connectors are sealed to lock out dust and moisture. Harnesses are braided for protection.

Individual cylinder heads Interchangeable for easy removal and visual inspection of internal parts.
