OVERVIEW

BENEFITS

FEATURES AT A GLANCE

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.
