Heating and Air Conditioning vents evenly distribute airfl ow within the cab. The cab can also feature optional dual pane glass for extreme cold weather environments for further operator comfort.
All D6R controls are ergonomically designed for low-effort and ease of operation. The dozer and ripper control levers feature pilot-operated hydraulics for added operator comfort and precise control. When the AccuGrade system is activated, the dozer is electro-hydraulically controlled. When the operator returns to manual control, the dozer is operated through the pilot hydraulic system.
With the touch of a finger, the rocker switch activates high or low idle. A decelerator pedal gives the operator full control of engine speed when the rocker switch is in the high idle position. Engine speed can also be easily set in any range between high and low idle by simultaneously using the decelerator pedal to set the desired speed and pressing the throttle switch in for three seconds.
The operator uses a single handle control to perform all direction and gear selection. The tiller bar control allows the operator to work more precisely in close areas around structures, grade stakes and other machines. Differential Steering provides the finest modulation in the industry.
The work tool lock-out valve prevents inadvertent operation of the hydraulic work tool attachments for added safety.
Caterpillar is one of the world’s leading engine manufacturers. Every component of a Cat® engine is carefully designed to maximize durability and reliability. Precise controls optimize power and fuel efficiency while reducing emissions. Modular design and advanced electronic diagnostics enhance the engine’s serviceability.
The D6R features a Cat C9 engine with ACERT™ Technology. A series of Caterpillar innovations provide advanced electronic control, precision fuel delivery and refined air management, resulting in outstanding performance and lower emissions. To help customers work within expanding global regulatory requirements, the C9 engine with ACERT Technology has been certifi ed to China Stage 2 (GB 20891-2007) emissions compliance.
The air-to-air aftercooler (ATAAC) – part of the advanced air management system – brings cool air to the engine. This increases life, reduces emissions, and helps maximize fuel effi ciency.
Multiple injection fuel delivery very precisely controls the combustion cycle. This lowers combustion chamber temperatures to reduce emissions and translates into more work output per unit of fuel. The Hydraulic Electronic Unit Injector (HEUI™) fuel system controls injection pressure over the entire engine operating speed range for complete control over injection timing, duration, and pressure.
Design creates near-perfect joint alignment, maximizing rod bearing life. This, in combination with a high effi ciency oil filter, ensures long engine life.
Advanced oil filters provide outstanding contamination control for a much cleaner running engine. The advanced filtration is accomplished without the shorter change intervals often required with other brands.
The all new cooling system includes engine radiator, Air-to-Air After Cooler (ATAAC), and hydraulic oil cooler. Engine radiator consists of two units of bar plate cooler, which are connected at the top with hose. The aluminum bar plate construction provides improved durability to debris plugging, abrasion and corrosion resistance.
The power shift transmission, unique Cat torque divider and differential steering are matched with the C9 engine to deliver outstanding power and reliability. The integrated system efficiently puts more power to the ground, utilizing more of the available horsepower, so you get more done with less.
Differential steering puts you on the leading edge of productivity by maintaining power to both tracks while turning. When one track speeds up, the other slows down an equal amount. Maneuverability – especially with large blade loads – is improved, as well as cycle times in some applications. Greater load capacity, power and speed control are possible in soft underfoot conditions on steep slopes because both tracks are powered during turns. A single tiller bar controls all directional and speed functions for ease of operation.
A unique Cat torque divider sends 70 percent of engine torque through a converter and 30 percent through a direct drive shaft for greater driveline efficiency and higher torque multiplication. The D6R torque divider provides high reliability and low dynamic torque. Components are designed to absorb full engine power, and deliver an optimum combination of operator efficiency and driveline reliability.
The transmission includes three speeds forward and three speeds reverse, featuring thick, large diameter, high capacity, oil-cooled clutches. These clutches provide higher torque capacity and increase service life. The planetary power shift transmission has a proven, robust mechanical control system. Modular transmission and differential slide into rear case for servicing ease, even when a ripper is installed. An oil-to-water cooler provides maximum cooling capacity, and forced oil flow lubricates and cools clutch packs for maximum clutch life.
The foundation of every Cat dozer is a rugged frame built to absorb high impact shock loads and twisting forces. A reinforced saddle, welded front cross-member and steel castings on the main case add to the overall strength.
The pivot shaft is bolted to the mainframe and connects to the rear roller frames to allow independent oscillation. The pivot shaft distributes impact loads through the case. This design eliminates alignment problems and the need for diagonal braces on the roller frames.
The pinned equalizer bar gives the roller frames the ability to oscillate up and down to better match ground contours for maximum traction and operator comfort. Bolted end pins offer longer life and reduce downtime with improved serviceability and reliability. A remote lubrication point in the engine compartment provides easy access to lubricate the center pin of the equalizer bar as part of scheduled maintenance practices.
Ground and implement shock loads are transferred to the mainframe to protect final drives, axles and steering components from harsh impacts for longer component life.
Modular power train components make it quick to remove and repair the transmission, fi nal drives, steering differential or brakes.
Modular undercarriage components simplify service. Lifetime lubricated idlers and track/carrier rollers provide the ability to re-use internal components and rebuild or reshell components. This reduces owning and operating costs, and saves raw materials and natural resources.
Since its ground-breaking introduction in 1978, more than 100,000 Cat Track-Type Tractors have been sold with the elevated sprocket “high drive” undercarriage. This is a fi eldproven design that offers outstanding machine performance and longer component life.
The elevated sprocket design gives the operator excellent sight lines to the blade, sides and back of the machine. However, machine center of gravity remains low, offering excellent stability, balance and traction.
Standard Heavy Duty undercarriage components are designed for extended wear life in abrasive conditions and high impact applications like forestry, side-slopes, or working in rocky or uneven terrain. Heavy duty track is designed for enhanced penetration. The leading and trailing edges of each track shoe overlap the adjacent shoe to increase durability and component life.
Optional SystemOne undercarriage for XL and LGP machines can help reduce total undercarriage owning and operating costs in many applications. SystemOne features lifetime sealed and lubricated cartridges to eliminate bushing turns, and sprockets require no replacement during the life of the chain designed to work and wear as a system.
Three (3) Undercarriage Arrangements are available:
Moderate Service and Extreme Service track shoes are available for both Heavy Duty and SystemOne Undercarriage to help optimize the machine based on its most frequent applications.
L-shaped push arms bring the blade closer to the machine, providing excellent maneuverability, balance and blade penetration. The design provides solid lateral stability and better cylinder positions for constant pry-out independent of blade height.
Field-proven, load-sensing, pilot controlled hydraulics respond to operating requirements by automatically and continually adjusting hydraulic power to maximize work tool effi ciency.
Blade designs feature a strong box-section design, made from steel with high tensile strength to stand up to the most severe applications. Heavy moldboard construction and hardened bolt-on cutting edges and end bits add strength and durability.
The three-shank parallelogram style ripper is available with curved or straight ripper shanks. This ripper is an excellent tool for preparing hard-packed material before dozing operations.
Optimize balance for backing up steep slopes or increasing performance in heavy dozing applications and if another rear attachment is not specifi ed.
See your Cat dealer for available Winch options best suited to your applications.
The AccuGrade system automates blade control for improved grading accuracy and more cost effective operation. Sensors calculate precise blade slope and elevation, then automatically adjust the blade to maintain grade. Automated blade control improves effi ciency by reaching grade faster and in fewer passes, reducing the need for traditional survey stakes or grade checkers.
AccuGrade systems and controls can be integrated from the factory, making system installation and setup quick and easy. Integration also provides greater system protection and reliability.
Three (3) systems are available to match the AccuGrade Ready Option integrated ex-factory selection. All calculate necessary blade adjustments to achieve grade, make automatic blade adjustments and calculate cut/fi ll requirements.
The optional Product Link* system is a factory installed or easily retrofitted wireless system that simplifi es equipment fleet tracking. Using satellite or cellular technology, it automatically reports key machine parameters such as location, machine hours, active and logged service codes and security alarms.
Cat machines are designed with serviceability in mind. Modular components, easy access to regular service points and features that enable quicker diagnostics all add up to less maintenance time and more time on the job.
The D6R features a monitoring system that provides feedback to operators with easy-to-read gauges and warning lamps that allows the operator to concentrate on the job at hand.
With the use of a Cat Electronic Technician (ET), your Cat dealer can determine historical performance parameters of the machine.
The Cat Monitoring System is designed to:
Monitor machine health and identify key maintenance needs before they lead to downtime through Cat Scheduled Oil Sampling. Cat machines feature live sampling ports for the engine oil, power train hydraulics and coolant. Cat oil sampling offers accurate analysis using tests designed by Caterpillar for Cat products, as well as knowledgeable interpretation of the results.
Major components on the D6R are built to be rebuilt, extending the useful life of the machine. Machine and component rebuilds save money, and offer a sustainability element by saving raw materials and natural resources. See your Cat dealer to learn more about rebuild options.
