794 AC

• 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.
