794 AC
The Cat® 794 AC electric drive truck delivers a full 327-ton (297-tonne) 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. 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.
SAFETY
- 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.
PRODUCTIVITY
- 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.
OPERATOR COMFORT
- 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.
VERSATILITY
- 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.
SERVICEABILITY
- 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.
DURABILITY AND LONG LIFE
- 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.
PROVEN AC DRIVE & POWERTRAIN
- 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.
SUSTAINABILITY
- 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.
TECHNOLOGY SOLUTIONS
- 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.
CAT BODIES
- 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.
