797F
797F Mining Truck
What makes the Cat® 797F Mining Truck the most productive 363-tonne (400-ton) truck in the market? Is it the best-in-class payload? Superior braking that leads to confident, productive operators? Or a tough, rugged frame that delivers performance and long life no matter the conditions? Today’s 797F delivers all of this—and more. It’s fast, fuel efficient and delivers class-leading productivity, making it the industry benchmark for lower cost per ton in its size class. 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
- Wide walkways, ladders, catwalks and service platforms; slip-resistant surfaces and guard rails; wide secondary egress ladder and a rear service access ladder; and optional powered access ladder.
- Integral ROPS structure resiliently mounted to the main frame to reduce vibration and sound.
- Lockout/tagout box mounted on the front bumper that includes engine shutdown switch, battery lockout, starter lockout and transmission lockout.
- Standard Cat MineStar™ Detect Object Detection system, which combines radar and camera systems to warn operators about hazards within the immediate vicinity.
- Optional Driver Safety System alerts the operator if fatigue or distraction are detected.
PRODUCTIVITY
- Cost per ton advantage over competitive models in higher altitudes, ranging from 6% to as high as 14%, plus HP Body option reduces weight an additional 2.0-5.0 tonnes (2.2-5.5 tons).
- Optimal speed on steep grades, poor underfoot conditions and haul roads with high rolling resistance for faster cycle times when compared to competitive trucks; travels loaded at a top speed of 60 km/h (42 mph).
- Unequaled lugging force during acceleration thanks to 23% net torque rise.
- Constant power over a wide range of operating speeds thanks to Cat seven-speed planetary power shift transmission.
- Low-speed movement control and unsurpassed stall torque delivered by lock-up torque converter.
FUEL EFFICIENCY
- Multiple power settings that allow you to operate at full power or in economy mode, so you can decide how much power you need.
- Modes that fine-tune hydraulic and engine output to match the job at hand; Eco-mode shown to deliver fuel savings of up to 3.5% per cycle.
- Optimized fuel calibrations available for Tier 4, high altitude and lesser regulated applications.
- Engine ECM that does not inject fuel into the cylinders during retarding applications, for exceptional fuel economy — zero fuel burn during retarding.
- Increased fuel efficiency with Tier 4 configuration.
VERSATILITY
- Proven high production in the most challenging conditions—from extreme cold and soft underfoot conditions to high-altitude, deep copper applications.
- 20-cylinder, quad-turbocharged Cat C175 engine produces 2983 kW (4,000 hp) of power for fast acceleration; 2647-kW (3,550-hp) setting for applications that don’t require the highest power, such as the flat hauls found in many coal and iron ore applications.
- Excels at high altitudes, with 4x4 engine configuration that offers payload and greater speeds with no impact on fuel burn.
OPERATOR COMFORT & CONTROL
- Two options to equip 797F with the desired features for your operation.
- Ergonomic layout, excellent all-around visibility, and controls, levers and switches that are positioned for ease of use.
- Includes dozens of features designed to enhance comfort, such as reduced vibration and sound suppression.
- Next generation seat includes a height adjuster; adjustable shoulder stock to keep seatbelt from rubbing on the operator’s neck; and seat back, side and lumbar bolsters to increase stability.
- Four-corner oil-cooled brakes and Automatic Retarding Control to improve handling and machine control so operators can work quickly and confidently.
SERVICEABILITY
- Time-saving features such as long service intervals; grouped ground-level maintenance and checkpoints; oil level sight gauges and front wheel sight glass; and service platforms on the engine and transmission.
- Increased life for the majority of filters —in many cases doubling lives to 2,000 hours and extending replacement intervals to four months.
- Optional 100% airless electric start option that eliminates air system maintenance from the machine and improves uptime.
- Electronic Clutch Pressure Controls (ECPC) diagnostics
- Optional fast-fill service center and brake wear indicators.
DURABILITY AND LONG LIFE
- Only truck in its size class to achieve high-hour milestones of 130,000 or more hours.
- Greater than 5% tire life improvement, significant engine life increase, plus major drive train component life improvement.
- Over 80% of frame is cast, not fabricated steel plate.
- Box-section design, which incorporates two forgings and 14 castings in high-stress areas with deep penetrating and continuous wrap-around welds to resist damage from twisting loads without adding extra weight.
- Frame, powertrain, engine and components that are built to be rebuilt — delivering multiple lives of like-new performance at a fraction-of-new price.
CAT BODIES
- Bodies designed to be an integral part of the entire vehicle system, ensuring maximum chassis life.
- High Performance (HP) body features lightweight, simplified and durable design that provides complete front machine coverage and extended overhead protection.
- Oil sands body specifically designed for use in challenging Canadian Oil Sands applications.
- HP-XL body, a version of the standard HP body with an extended length floor, designed to neutralize extreme forward bias loading applications.
SUSTAINABILITY
- Designed to use less fuel, which reduces engine emissions, and there is zero fuel burn during retarding; optional Tier 4 Final engine reduces NOx and particulate matter.
- Less waste thanks to features like rear axle filtration, extended life filters and longer maintenance intervals.
- Cat Common Rail Fuel System, which provides optimal fuel delivery, reducing both fuel consumption and emissions output.
- Engine compatible with diesel fuel blended with lower-carbon intensity fuels such as biofuels and renewable fuels.
- Cat Rebuild and Cat Reman programs, which preserve raw materials, conserve energy and reduce emissions.
TECHNOLOGY SOLUTIONS
- 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.
- Standard 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.
