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.
The Cat engine, AC drive system, hydraulics and controls have been integrated to make the 794 easy to operate, providing excellent slow speed control within the service areas and superior throttle response on acceleration to move out of the loading or dump areas. Integration of the engine and powertrain delivers low operating costs through electronically combined powertrain components.
— 100% designed, validated and built by Caterpillar
— Full support of Cat dealer and parts network
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 794 AC to use less fuel, which reduces engine emissions and carbon footprint. The optional Tier 4 Final / Stage V engine reduces NOx and particulate matter. And we've reduced oil usage and filter change intervals.
The Cat AC drive is a high voltage system (2,600 volts) that operates at lower current than most competitive trucks. When combined with Cat's total integration and design of the truck and drive system, the result is higher efficiency, lower heat generation, smaller and lighter components, and longer component life.
— The Enhanced Engine Oil Filtration (EEOF) package, eliminates the need for an engine oil filter change and reduces oil usages.
Engines with advanced technology contribute to better fuel economy and decreased emissions.
The 794 AC has exceptionally low oil and lube consumption when compared to the competition. This provides a reduced impact on the environment, lower cost of ownership, and less maintenance time.
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.
Thanks to a significant speed advantage, the Cat 794 AC lets you move more over the course of a shift — or move the same amount of material with fewer trucks.
— Lower empty weight
— Higher-rated GMW
— Higher-rated field payload than competitors
— Faster speeds
Optimized horsepower performance makes it possible for the 794 to run in all areas of the mine — from deep pits to downhill hauls; from smooth, flat roads to areas of high rolling resistance — with the same engine.
While higher horsepower is available to boost productivity in deeper pits, an easy adjustment to a lower horsepower allows the 794 to better align with mixed fleets and keep fuel costs lower. This horsepower setting is configured by software and doesn't require an engine change. In addition, body choices allow you to select, design and customize options based on your application.
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 794 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.
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 10/10/20 payload guidelines help achieve a balance of excellent payload with safe operation.
Integral to the truck the body is designed to fit with the chassis and work as part of the truck system. Each body is sized to meet the payload requirements without compromise to vehicle balance, braking or control.
The body is sized and configured to meet the specific needs dictated by fragmentation, abrasion, cohesion, and the loading tool to maximize the payload capability of the truck.
