Overview

Big Payloads. High Speeds. Superior Braking.

The Cat® 794 AC electric drive truck delivers a full 327-ton payload, increased speed on grade, 34% more retarding power than competitive trucks, superior braking performance and easier maintenance. The result? High availability, more confident operators and improved productivity. The 794 features a proven electric drive powertrain that is Caterpillar designed, integrated and supported. Validated on sites around the world, the 794 has proven its performance in a variety of applications, making it the ideal choice for a wide variety of applications. It hauls more every load, every cycle and every shift. And it delivers a better bottom line to the most important mine in the world: yours.

Benefits

Up To 8% Better Payload

Higher-rated field payload vs. competitive trucks thanks to lower empty weight and higher-rated GMW

34% More Retarding Power

Superior retarding power and four-corner wet disc brakes boost operator confidence

Up To 8% Better Speed on Grade

Can travel at top speed of 60 kph / 37 mph and at maximum 28% grade loaded

Features At A Glance

Greater visibility thanks to wide field of view from the cab.
Safer access and egress with standard 600 mm) (24 in) wide ladders, flat deck, toe kicks, and optional power access stair attachment.
Confidence-building features such as anti-rollback, traction controls, park brake warning when exiting the cab and automatic retarder.
Best braking in its class, with four-corner wet disc brakes with blended mechanical service brakes and dynamics, plus Automatic Retarding Control for easier and more efficient retarding.
Ground-level system lockout, engine lockout and propulsion lockout (in ECM cabinet), VIMS monitoring, and stored energy dissipation at shutdown.

Proven 90% physical availability.
Significant speed advantage to move more over the course of a shift — or move the same amount of material with fewer trucks.
Lower empty weight and higher-rated GMW for a higher-rated field payload vs. competitive trucks.
Ease of operation and reduced costs thanks to integrated Cat engine, AC drive system, hydraulics and controls.
Excellent slow speed control within the service areas and superior throttle response on acceleration to move out of the loading or dump areas.

Ergonomic cab layout, excellent all-around visibility, and controls, levers and switches that are positioned for ease of use.
Automatic climate control and reduced vibration and sound.
Next generation seat with height adjuster, adjustable shoulder stock to keep the seatbelt from rubbing, and seat back, side and lumbar bolsters to increase stability.

Proven in the field and working around the world — on four continents and in nine countries.
Ideal for a variety of applications and ores: soft rock, hard rock, deep pit, and flat haul; low altitude, high altitude, high ambient, and cold weather.
Optimized horsepower performance that 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.
Higher horsepower available to boost productivity in deeper pits, and an easy adjustment to a lower horsepower that allows the 794 to better align with mixed fleets and keep fuel costs lower.

Open engine access and platforms for service of engine, generator and inverter, plus ground-level filters and service.
Component layout with minimized hydraulics, all hydraulic lines on one side, and electric wiring on the other side.
Separate traction motors, brakes and final drives.
Modular component design for easy removal and installation.
AC grid blower motor designed for longer life and less maintenance, plus pressurized and filtered AC drive inverter that requires less maintenance.

Highly validated and proven straight frame rail design that eliminates the bends and breaks that can occur at stress concentrations.
Outstanding durability delivered by box section construction that uses Caterpillar proprietary steel specification for excellent welding characteristics.
Increased frame life thanks to deep section main rails in critical areas of the frame lower stress levels.
Frame, powertrain, engine and components that are built to be rebuilt — delivering multiple lives of like-new performance at a fraction-of-new price.

Reduced operating costs thanks to the integrated engine and powertrain 100% designed, validated and built by Caterpillar.
Radial style retarding grid with AC electric motor that requires no regular motor maintenance and is quieter and lighter than box grids.
AC Drive dynamic retarding for continuous retarding power, and an AC electric motor that reduces maintenance.
State-of-the-art high voltage IGBTs for maximum AC drive system efficiency, and a dual-bearing brushless alternator that delivers long life and less maintenance, with no shimming required.
Variable hydraulic blower fan, which provides optimized cooling even at idle for increased component performance and life.

Designed to use less fuel, which reduces engine emissions and carbon footprint.
Optional U.S. EPA Tier 4 Final / EU Stage V engine, which reduces NOx by 62% and particulates by 93% when compared to Tier 1 emissions.
Reduced waste thanks to Centrifugal Oil Filter (COF), Enhanced Engine Oil Filtration (EEOF) package, standard self-cleaning engine filter, extended oil change intervals and reduced oil usage.
Engines compatible with diesel fuel blended with lower-carbon intensity fuels such as biofuels and renewable fuels, plus power options like trolley.
Cat Rebuild and Cat Reman programs, which preserve raw materials, conserve energy and reduce emissions.

Equipped with standard Product Link™ Elite monitoring system, which delivers health and payload information to keep performance high and enable proactive maintenance planning.
Factory-ready for fully integrated Cat MineStar™ Command for hauling, an autonomous hauling solution proven to increase productivity up to 30%.
Optional MineStar Fleet, a fleet monitoring system, to measure, manage and maximize the overall hauling operation.
Optional MineStar Detect proximity detection system, which uses cameras to give operators a better view of what's happening around their equipment.
Optional in-cab Cat Driver Safety System (DSS) intervenes when operator fatigue or distraction are detected.

Bodies designed to fit with the chassis, sized to meet payload requirements and work as part of the truck system.
High Efficiency (HE) dump body option that is lightweight, simplified and durable.
With unique minimal structure design, HE body provides long life while minimizing weight for increased payload.
HE body sized and configured to meet the specific needs of the mine, dictated by fragmentation, abrasion, cohesion and the loading tool.

Cat Command for Hauling

Cat® MineStar™ Command for hauling 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. Command provides the fully integrated operation of autonomous mining systems, allowing them to haul more efficiently with near-continuous operation and move more with fewer people on site. Autonomous trucks operate safely around other equipment, light vehicles and personnel. Command trucks respond to calls to the shovel, move into position, haul to dump points and even report for maintenance — all without an operator on board.

Cat Health

Through regular monitoring of machine conditions, mines can adopt a more proactive approach to maintenance and repair. Equipment health data is a key contributor to that approach. Data helps mines identify equipment problems long before failure.

Accessing the right data at the right time is critical to improving operational intelligence and machine predictive analysis. Cat® MineStar™ Health helps you meet that need by connecting you to your machines and delivering that important information. The MineStar Health portfolio set consists of Connectivity Enablers that collect, convert and transmit equipment data; and Applications that visualize, analyze and report health equipment data.
