Cat® C175-16 Engine

The 793F has a Cat C175-16 quad turbocharged air-to-air aftercooled diesel engine that has enhanced power management capability for maximum hauling performance in your most demanding mining applications.

• The C175-16 is a 16-cylinder, four-stroke design that uses long, effective power strokes for optimum efficiency.

• Is compliant with U.S. Environmental Protection Agency emission requirements.

• The 20 percent net torque rise of the C175-16 provides unequalled lugging force during acceleration on steep grades and in rough underfoot conditions. Torque rise effectively matches transmission shift points for maximum efficiency and fast cycle times.

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

• The Cat Common Rail Fuel System is an 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.

• The flexible core design of the MESABI radiator means easier serviceability along with long life and high durability.

• You have two starter options: The tank on the standard air start system is ground level serviceable, while the electric start option allows the air system to be totally removed from the truck.

Mechanical Power Train

The 793F gives you the fastest truck on grade in its class. The Cat mechanical drive power train and power shift transmission provides you unmatched operating efficiency and control on steep grades, in poor underfoot conditions and on haul roads with high rolling resistance.

1 - Transmission with Electronic Clutch Pressure Control

The Cat six-speed planetary power shift transmission is matched with the direct-injection C175-16 diesel engine to deliver constant power over a wide range of operating speeds. The proven planetary power shift transmission is built tough and is designed for the higher power of the C175-16 engine. A dedicated oil tank and circuit provides cooler, cleaner oil for maximum performance and longer component life. Electronic Clutch Pressure Control (ECPC) provides maximum performance, smooth shifting, long clutch life and a more comfortable ride.

2 - Lock-Up Torque Converter

Combines maximum rimpull and cushioned shifting of torque converter drive with the efficiency and performance of direct drive. The lock-up torque converter engages at approximately 8 km/h (5 mph), delivering more power to the wheels.

3 - Final Drives

Cat final drives work as a system with the planetary power shift transmission to deliver maximum power to the ground. Built to withstand the forces of high torque and impact loads, double reduction final drives provide high torque multiplication to further reduce drive train stress.

Extended Life Wheel Stations

Developed for uphill hauling applications, this arrangement is designed to extend wheel life and hauling performance on long, uphill hauls. Extended life wheel stations are built with larger, more durable components, including larger spindles, wider wheel bearing spacing, a larger braking surface and additional discs in the front for longer brake life and more time between overhauls.

Additional Retarding

Developed for downhill-loaded applications, this option typically delivers an extra gear of retarding capability or 25 percent more speed on downhill grades. Additional retarding is achieved by adding larger brakes and additional brake cooling capability. This option requires the use of Extended Life Wheel Stations.

Engine/Power Train Integration

See more

Cat Data Link

Reduces operating costs through electronically integrating machine computer systems to optimize overall power train performance, increase reliability and component life.

Controlled Throttle Shifting

Regulates engine rpm during shifting to reduce power train stress and clutch wear by controlling engine speed, torque converter lock-up and transmission clutch engagement for smoother shifts and longer component life.

Directional Shift Management

Regulates engine speed during directional shifts to prevent damage caused by high speed, directional changes.

Body-Up Shift Inhibitor

Prevents the transmission from shifting above the pre-programmed gear without the body fully lowered.

Overspeed Protection

The transmission control electronically senses engine conditions and automatically up-shifts one gear to prevent overspeeding. If overspeeding occurs in top gear, the lock-up clutch is disengaged.

Programmable Top Gear

Transmission top gear maximum can be set using the Cat ET service tool to help the operator maintain speed limits.

Downshift Inhibitor

Prevents engine overspeeding by keeping the transmission from downshifting until engine speed reaches the downshift point.

Rapid Downshift Function

Does not allow a turnaround shift until approximately 2.3 seconds after a shift occurs.

Reverse Speed Inhibitor

Prevents shifts into reverse when forward ground speeds are in excess of 5 km/h (3 mph).

Cat Braking Systems

Integrated Braking System

Reliable performance and control in extreme haul road conditions is important for operator safety. The Cat oil-cooled braking system provides this. Integrated systems combine the service, secondary, parking brakes and retarding functions for optimum braking efficiency that does not burn fuel while retarding.

Oil-Cooled Multiple Disc Brakes

Cat four-wheel, forced oil-cooled, multiple disc service brakes are continuously cooled by water-to-oil heat exchangers 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.

Long Life

An oil film prevents direct contact between the discs. This design absorbs the braking forces by shearing the oil molecules and carrying heat away to extend brake life.

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.

Structures

Box Section Design

The 793F 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 have large radii with internal reinforcing ribs to dissipate stress in areas of high stress concentration. Castings move welds to lower stress areas for greater frame life.

Integral Four-Post ROPS Cab

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

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 to the frame and serve as steering kingpins for a tight turning radius with excellent maneuverability and low maintenance.

• Rear - Rear cylinders allow axle 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 directs stress to be more evenly distributed than an A-frame design and allows more service area around the transmission.

Steering System

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