Improved serviceability points and grouped service locations mean your truck spends more time on the haul road.

Engine

The Cat C175-20 quad turbocharged and air-to-air aftercooled diesel engine has enhanced power management capability for maximum hauling performance in your most demanding mining applications.

Design

The C175-20 is a 20 cylinder, single block, four stroke design that uses long, effective power strokes for optimum efficiency.

Long Life

High displacement, low rpm rating and conservative power ratings mean more time on the haul roads and less time in the shop.

Cat Common Rail Fuel System

The electronically-controlled system senses operating conditions and regulates fuel delivery for optimum fuel efficiency. This precise and flexible fuel system gives the engine the ability to meet emission regulations without sacrificing performance, reliability or durability.

Cooling System

The flexible core design of the MESABI radiator means easier serviceability along with long life and high durability. The MESABI radiator comes standard on the 797F.

Cat Truck Bodies

You have a choice of four MSD II (Mine Specific Design) bodies in conjunction with a configurable liner system to achieve the most efficient hauling solutions at the lowest-cost-per-unit-of-production.

MSD II Body

The MSD II bodies are the number one choice in the mining industry. The internal body shells are designed and manufactured for superior impact and wear protection. Coupled with the Caterpillar mine specific design process the MSD II bodies optimize the balance of payload and durability.

Truck Body Liners

A variety of liner options are available to save weight and extend body life through impact and wear management. The mine specific design system is utilized to provide you with the optimum liner for long life at your mine site.

Road Analysis Control

Optional system measures frame rack, bias and pitch to help identify haul road problems so they can be repaired. This leads to improved cycle time, component lives and fuel efficiency.

Fuel Efficiency

The engine provides additional retarding by running against compression on downhill hauls. During retarding applications the engine ECM does not inject fuel into the cylinders for exceptional fuel economy.

797F Gradeability/Speed/Rimpull*

To determine gradeability performance: Read from gross weight down to the percent of total resistance. Total resistance equals actual percent grade plus 1% for each 10 kg/t (20 lb/ton) of rolling resistance. From this weight-resistance point, read horizontally to the curve with the highest obtainable gear, then down to maximum speed. Usable rimpull will depend upon traction available and weight on drive wheels.

Suspension System

Designed to dissipate haul road and loading impacts for longer frame life and a more comfortable ride. Durable Design – Rugged cylinders utilize large diameter bore and low pressure nitrogen/oil design for long life with minimal maintenance. Front – Front cylinders with preset caster and camber are mounted on the frame and serve as steering kingpins for a tight turning radius with excellent maneuverability and low maintenance. Rear – Rear cylinders allow oscillation and absorb bending and twisting stresses caused by uneven and rough haul roads rather than transmitting them to the main frame.

Four-Bar Link Rear Suspension

The four-bar link suspension transfers and supports loads to the frame more efficiently than an A-frame design and allows more service area around the transmission.

Sustainability Features

The 797F Mining Truck offers continuous rear axle filtration, extended life filters and extended maintenance intervals, which aid in decreasing the amount of waste contributed to our environment.

Integrated Braking System

The Cat, oil-cooled braking system delivers you reliable performance and control in extreme haul road conditions. The integrated system combines the service, secondary, parking brakes and retarding functions in the same system for optimum braking efficiency that does not burn fuel while retarding.

Oil-Cooled Multiple Disc Brakes

Cat four wheel, forced oil-cooled, multiple disc brakes are continuously cooled by water-to-oil heat exchanger for exceptional, non-fading braking and retarding performance.

Brake Design

Cat, oil-cooled disc brakes are designed with large discs and plates for reliable, adjustment-free operation and performance. Brakes are completely enclosed and sealed to prevent contamination and reduce maintenance.

Parking Brake

Oil-cooled, spring-applied, hydraulically released parking brake is applied to all four wheels for superior parking capability on all grades up to 15 percent.

Hydraulic Automatic Retarder Control (ARC)

Hydraulically activated, automatic retarder control system electronically controls retarding on grade to maintain optimum engine rpm and brake system performance. ARC is now adjustable in each gear.

Steering System

Hydraulic steering control system is designed for exceptional smoothness and precise control. A separate circuit prevents cross contamination for long life.

Cat Detect System

Knowing what’s around your 797F at all times is important. The Cat Detect system is factory installed as standard equipment on 797F Mining Trucks. The full Cat Detect system, RADAR AND CAMERA, provides both audible and visual indications of detected objects. This system uses a combination of short and medium range radars which surround the machine, along with cameras on each side to allow the operator to confirm the detected object. The cameras supplement the radar alerts and are selectable by touch screen menus through an intuitive interface.

Body Selection

The Cat truck body program is committed to providing you the most efficient and highest value body solution for your operation. By studying your mine site and understanding the overall operational requirements and constraints, the body can be configured to meet the unique needs of your application.

Box Section Design

The 797F frame uses a box-section design, incorporating 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. Steel Structures – Mild steel used throughout frame provides flexibility, durability and resistance to impact loads, even in cold climates and allows for easy field repairs. Castings – Castings account for 80 percent of the frame’s weight and are key to providing durability in some of the world’s toughest conditions. The large radii castings are resilient to frame flexing and ensure long life.

Isolation Box

Lockout, tagout box mounted on front bumper includes engine shutdown switch, battery lockout, starter lockout and transmission lockout.

Integral Four-Post Cab

Resiliently mounted to the frame to reduce vibration and sound, the integral ROPS is designed as an extension of the truck frame.

Ergonomic Layout

To minimize operator fatigue and maximize productivity the all new F-Series operator station is ergonomically designed for total machine control in a comfortable, productive and safe environment. Controls, levers, switches and gauges are positioned for ease of use.

Viewing Area

Designed for excellent all-around visibility and clear sight lines to the haul road, the large viewing area offers exceptional visibility, allowing the operator to maneuver with confidence for high productivity. The air cleaners have been relocated to the front of the truck, allowing the operator increased visibility.

Access and Egress

Improvements for machine level access and egress include a standard 600 mm (24 in) diagonal stairway across the front of the machine. Improvements for ground level access include an optional powered access stairway.

Advanced Surface Technology (AST)

Advanced Surface Technology (AST) is a replacement for hard chrome coatings on some steel parts, including suspension and hoist cylinder rods. This technology improves wear resistance and reduces repair time. Chrome has been eliminated to reduce environmental impact.

Servicing Ease

Easy access to daily service points simplifies servicing and reduces your time spent on regular maintenance procedures. Enhanced serviceability and long service intervals are designed to increase machine availability and productivity.

Ground Level Access

Grouped ground level points allow you convenient servicing of tanks, filters, drains, batteries, AutoLube system, pressure taps, screens, fluid sight gauges and engine shutdown. Ground level VIMS data port permits easier downloading of information.

Sealed Electrical Connectors

Electrical connectors are sealed to lock out dust and moisture. Harnesses are braided for protection. Wires are color-coded for easy diagnosis and repair.
