796 AC Electric Drive Mining Truck
The Cat® 796 AC electric drive truck offers more flexibility than any other truck in its size class — delivering optimized performance and better productivity. Built on a proven truck architecture and high strength structures, the 796 AC delivers a nominal target payload of up to 327 tonnes (360 tons) regardless of attachments. Add in a proven drive system with industry-leading serviceability, and the 796 AC mining truck delivers a hauling solution you can depend on — resulting in high reliability, high availability, and low lifecycle costs. By hauling more every load, every cycle and every shift, it creates a low-cost-per-ton hauling operation that delivers a better bottom line.

SAFETY
- Greater visibility thanks to wide field of view from the cab and radial retard grid that improves right-hand view.
- Safer access and egress with 600-mm-wide (23.6-in-wide) ladders, flat deck, toe kicks, and optional power access stair attachment.
- Confidence-building features such as anti-rollback, traction controls, reverse shift inhibitor, Automatic Retarding Control, and door sensor warning for park brake application.
- Full dynamic retarding through a compact radial grid, backstopped by the proven design of Caterpillar four-corner oil-cooled brakes, for stable handling and confident stopping.
- Fully independent secondary brake system that provides emergency controllability with a hydraulically actuated secondary brake pedal that serves as a backup to electronic controls.
PRODUCTIVITY
- Achieves a true class-leading 327-tonne (360-ton) payload regardless of local attachments.
- Ease of operation and reduced costs thanks to deep integration of Cat engine, AC drive system, hydraulics and controls.
- End-to-end visibility of all truck parameters for optimized fuel efficiency, speed on grade and parasitic loads across the operating range.
- Excellent slow speed control within service areas as well as superior motor torque and acceleration pulling away from the shovel.
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.
SERVICEABILITY
- High displacement, low rpm rating and conservative horsepower ratings, which mean more time on the haul road and less time in the shop.
- Inlet manifolds and turbochargers that are located outside of the engine's V, giving the service technicians more space to work on top of the engine and within the engine bay.
- Engine and dual bearing drive alternator that can be serviced separately, eliminating shimming.
- Sealed and pressurized inverter cabinet that requires no cleaning, eliminating recurring maintenance.
- Engine walkways and service platforms, modular components and ground-level grouped service points.
DURABILITY AND LONG LIFE
- First overhaul life of 25,000 hours for lower cost of ownership, with proven C175 engine and electric drive system.
- 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.
- High voltage system that operates at lower current than most competitive trucks, contributing to higher efficiency, lower heat generation, smaller and lighter components, and longer component life.
- 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; AC electric motor that reduces maintenance; and state-of-the-art high voltage IGBTs for maximum AC drive system efficiency.
- 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), 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.
