The lock-up torque converter combines the maximum rimpull and cushioned shifting of torque converter drive with the efficiency and performance of direct drive.
The seven-speed, planetary power shift transmission utilizes pressure valve to regulate clutch pressure rise and fall to ease clutch engagement. This reduces shock loads on power train components.
Final drives and differential torque multiplication of 13.15:1 further reduces stress on the drive train.
Transmission and torque converter share a common sump. The combined sump offers an easily accessible fill tube and site gauges.
Full floating axles are shot peened to relieve internal stresses and increase durability. Rolled splines also provide increased service life.
Cat rear wheels and Cat center-mount rims are mounted using studs and nuts to minimize maintenance and maximize durability.
Transmission chassis Controller (TCC) uses electronically transferred engine rpm data to execute shifts at preset points for optimum performance and efficiency.
Caterpillar's power train integration provides increased component life and operator comfort.
The Cat 3408E Diesel Engine is a four-stroke design that uses long power strokes for more complete fuel combustion and optimum efficiency.
The torque rise provides high lugging force during acceleration on grade or in high rimpull conditions.
The Hydraulic Electric Unit Injector (HEUI) is a proven high-pressure, direct injection fuel system. This system electronically monitors operator and machine inputs to optimize engine performance.
The Electronic Control Module monitors key functions and logs critical indicators.
The CAT Data Link electronically integrates the machine's computer systems, which allows communications.
Electronic Technician (ET) enhances diagnostics/serviceability. The electronic engine and transmission controls provide exhaustive diagnostic capability for service technicians.
Caterpillar Electronic Monitoring System (CEMS) allows the operator to view requested information and utilizes a three-category warning system to alert operator to abnormal machine conditions.
Caterpillar offers optional attachments that integrate with the CAT Data Link System.
Caterpillar forced oil-cooled, multiple disc brakes are continuously cooled for exceptional, fade-resistant braking and retarding.
Oil-cooled disc brakes are designed and built for reliable, adjustment-free operation providing superior performance and service life in comparison to shoe-type and dry-disc system.
An oil film prevents direct contact between the discs. Absorbing the braking forces by shearing oil and carrying heat away, this design brake life.
A Caterpillar patented, two-piston design combines the service, secondary, parking brake, and retarding functions.
When retarding, the engine runs against compression on downhill hauls, resulting in minimal fuel burn.
The 769D frame uses a box-section design, incorporating 17 castings in high-stress areas, with deep-penetrating and continuous wrap-around welding.
Castings have large radii with internal reinforcing ribs to dissipate stress. Castings move welds to lower stress areas and provide two to three times the strength of equivalent-sized fabricated structures.
The 769D frame provides for ease of serviceability.
The Rollover Protection Structure (ROPS) attaches securely to four castings welded into the frame.
The suspension system is designed to dissipate haul road and loading impacts for extended frame life.
769D bodies are designed to handle a variety of material densities. Maximum payload is reached in three to five passes from a matched Cat loader.
Sidewall and floor junctions are joined by 5-sided beams to resist impact loading and sustained hauling stresses.
Box-section beams offer increased durability in the floor, sidewalls, top rail, corner and cab canopy areas.
400 Brinell Steel wear surfaces provide excellent wear resistance and are easily welded without preheating procedures.
Two-stage hoist cylinders provide fast dump cycle times.
Standard body comes exhaust heated with options including a full-time muffler or exhaust diverter.
Custom attachments including tail extensions, liner packages, sideboards, and other custom designs are offered to help ensure rated payload.
The wraparound dash panel is provided in an easy line-of-sight arrangement, using LED backlit rocker switches.
The Caterpillar Contour Series Air Suspension seat is standard. The seat is fully adjustable and includes an adjustable right-hand armrest.
Tilt/telescoping steering wheel with ergonomic grip improves comfort and control.
Transmission console has LED backlit gear numbers and ergonomic shift knob.
Exceptional all-around visibility reduces fatigue and improves productivity.
Integral, sound-suppressed ROPS/FOPS Cab is resiliently mounted providing a quiet, protected work environment.
Front brake cut-out switch increases front brake component life.
Large storage compartment is located under the trainer's seat.
Trainer's seat with increased hip/shoulder room, backrest, and retractable seat belt.
Caterpillar Electronic Monitoring System (CEMS) provides critical data. The system features three separate displays.
A standard heater and optional air conditioner with four-speed fan and nine vents.
Ergonomically designed foot pedals for increased operator comfort. Secondary brake moved to floor.
Electric power window for simplified operation.
Electrohydraulic hoist lever is finger tip actuated and provides low-impact body-down snubbing.
Truck Production Management System (TPMS) - optional - provides payload and cycle time data.
With the accelerator depressed and/or ARC turned off, ARC will automatically activate at 2,475 rpm to help avoid potentially destructive and often costly engine overspeeds.
ARC results in increased operating efficiency with faster downhill speeds. By maintaining consistently higher engine speeds, average truck speed will be higher than a manually controlled truck.
ARC results in excellent controllability and reduced operator effort. Automatic brake modulation provides a smoother ride over manual modulation, allowing the operator to focus more on truck operation down the haul road.
ARC results in improved component life, optimized system cooling capability, and reduced torque fluctuations result from the precision of ARC.
ARC results in faster troubleshooting and diagnosis with self-diagnostic capability and the ability to communicate with ET through the CAT Data Link System.
Operator awareness through electronic integration and the CEMS, alerting the operator to overspeed conditions and critical machine functions.
TCS provides operator awareness through an on-dash indicator, signifying TCS is engaged.
TCS utilizes normal differential action to provide superior maneuvering in poor underfoot conditions.
TCS divides torque equally to reduce stress created on final drives and axles when torque is transferred to one side.
TCS maintains the back-up design. Should the sensors fail, normal differential action is still available to maintain control and steering.
Body options include a full line of standard and custom designs based on specific customer preference, material density, loading tools and site conditions.
A full line of tire options, representing various manufacturers, is offered by Caterpillar to maximize performance and life for specific applications.
Attachments give the customer options to tailor trucks for specific application requirements, including Truck Production Management System, Automatic Retarder Control, Traction Control System, Custom product offerings, and Muffler/exhaust diverter.
The Caterpillar system approach means increased efficiencies through "common design".
The Caterpillar Production Analysis Team (PAT) and Caterpillar software programs can assist customers with detailed, application evaluation.
The maintenance platform provides access to air tank, brake master cylinder, and make-up tank, engine oil level, air filters, steering hydraulic tank, and battery compartment.
