Overview

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.

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).

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.

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.

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.

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.

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.

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.

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.

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.
