The truck is available in multiple emissions configurations to meet various regulatory needs around the world.

BUMPER-TO-BUMPER CATERPILLAR

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.

YOUR PARTNER FOR THE COMPLETE EQUIPMENT LIFECYCLE

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.

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

UP TO 9% LESS FUEL CONSUMPTION WITH TIER 4 ENGINE.
We've designed the 785 with a number of enhancements that lessen its impact on the environment. Features like oil renewal systems, continuous rear axle filtration, extended life filters and longer maintenance intervals decrease the amount of waste contributed to the environment.
— The optional Tier 4 Final engine reduces NOx and particulate matter. And because they're more efficient, the 785s burn less fuel, and there is zero fuel burn during retarding.

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.

EMISSIONS OPTIONS

The 785 is available in two options to meet the emissions regulations where you operate. The 785 is available in those countries that are less strictly regulated. The optional Tier 4 Final engine meets the strictest regulations.

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.

OPTIMIZED PAYLOAD

Contradicting a common belief that bigger is better, the 785 has a weight advantage over larger trucks so you can haul more with every load. The 785 maintains the same payload and same pass match as previous models, even with the Tier 4 Final / Stage V system installed.

The Truck Payload Monitoring System has been improved for next generation trucks to provide more accurate measurement, improved monitoring and an improved interface.

MORE POWER, LOWER COSTS

The 785 is powered by the 3512E engine, which delivers high power and reliability and contributes to overall lower operating costs. The 12-cylinder four-stroke design uses long, effective power strokes for more complete fuel combustion and optimum fuel efficiency.

The 23% net torque rise provides unequaled lugging force during acceleration, on steep grades and in rough underfoot conditions. High displacement, low rpm rating and conservative horsepower ratings mean more time on the haul roads and less time in the maintenance shop.

Lowering Total Fluid Consumption Cost

Improved 3512E engine meets U.S. EPA Tier 4 Final emission standards, and features the Cat Selective Catalytic Reduction (SCR) system that provides the least Total Fluid Consumption cost with greater reliability.

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.

Cutting-edge Connectivity

The new Cat 785 features enhanced connectivity with faster data transfer to improve access to information. Through a two-wire ethernet, machine components communicate faster and transfer more data. Every machine from the factory comes standard with Product Link™ cellular connectivity as well as an option to communicate through dual-mode cellular 4G/LTE and satellite, or local Wi-Fi networks . The new Cat Next Generation telematics platform makes it easier for more data collection and faster transmission to locally hosted or cloud-based applications, such as Cat MineStar™ Fleet, MineStar Edge through the Cat Next Generation telematics platform.

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.

FLEET

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

DETECT

With the MineStar Detect proximity detection system, you can equip your 785 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.

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.
