Benefits & Features
Operator Station
Cab
The D6T cab is designed and equipped for operator productivity, safety and comfort. An isolation-mounted, pressurized cab reduces noise and vibration. Large single-pane windows offer an excellent view to the sides over the track and to the blade corners. The low rear window enables excellent rearward visibility and lets the operator see the ripper tip. The tapered hood, notched fuel tank, and narrow single-shank ripper carriage give the operator a clear line of sight to front and rear work areas while traversing on the job site.The Cat Comfort Series seat is well padded and adjustable, with bolsters to comfortably restrain operator side-to-side movement when working on grades or slopes. Armrests are adjustable without tools, and heating/air conditioning vents evenly distribute airflow. The cab is pre-wired for a radio and equipped with two speakers, an antenna and a radio mount recessed in the headliner. A 10-amp, 12-volt power converter is also included to provide convenient supplemental power for cellular phones and computers.
Engine
Engine
Every component of a Cat engine is carefully designed to maximize durability and reliability. Precise controls optimize power and fuel efficiency while reducing emissions.The D6T features a Cat C9 engine with ACERT™ Technology. A series of Caterpillar engineered innovations provide advanced electronic control, precision fuel delivery and refined air management, resulting in outstanding performance and lower emissions. The C9 engine with ACERT Technology meets U.S. EPA Tier 3 and European Union Stage IIIA and Japan MLIT Step 3 emissions standards.Modular design and advanced electronic diagnostics enhance the engine's serviceability. An optional sand blast grid equips the machine for high airborne debris applications, and a demand fan saves fuel in low ambient temperature conditions.
Structure
Structures
The base 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 frame is designed for those customers who rebuild the tractors for a second or third machine life and offers the best-in-class durability.The D6T VPAT “C” frame has fabricated box-beam type side rails, and the trunnion joint is located in the saddle to allow the dozer side loads to go into the mainframe instead of through the radiator guard.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 or down independently to better match ground contours for maximum traction and operator comfort. Bolted end pins to offer longer life and reduce downtime with improved serviceability and reliability.
Power Train
Two Pump Hydraulic System
A dual hydraulic pump design provides dedicated hydraulic power to steering and implements for a 20 percent steering improvement. The slip pump design improves response in simultaneous steering/implement applications, resulting in a machine that is more maneuverable overall. The constant flow in steering circuit improves hydraulic cooling, increasing cooling capacity of machine.
Multi Velocity Program (MVP)
This exclusive machine control system allows the operator to choose from five speed ranges in Forward and Reverse to best match machine speed to applications and ground conditions. MVP improves productivity in light applications (partial blade loads), where more speed flexibility is desired.
Differential Steering System
Differential steering maintains full power to both tracks while turning providing best in class turning with a loaded dozer blade. 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. Low effort tiller bar, touch shift control and steering modulation insure ease of operation.
Implement and Steering Controls
Steering and Transmission Control
Turns and directional changes are controlled with a single tiller handle. Buttons change the electronically controlled powershift transmission. Operators are able to work precisely in tight areas and around obstacles with the finest modulation in the industry.
Dozer and Ripper Control Levers
The D6T features ergonomically designed dozer and ripper controls with low-effort, pilot-operated hydraulics. When equipped with a VPAT blade, the blade control allows simultaneous six-way control of the blade with a thumb rocker. The dozer control is equipped as an electro-hydraulic control when the AccuGrade Ready Option is installed.
Throttle Rocker Switch
The fingertip 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 be set between high and low idle by simultaneously using the decelerator pedal and holding the Rabbit side of the throttle switch for three seconds.
Work Tool Lock-Out Switch
Work tool lock-out prevents inadvertent operation of hydraulic work tool attachments.
Auto-Shift/Auto-Kickdown
Operators can pre-select a forward and reverse speed setting for easy, efficient directional changes. Auto-shift settings include first forward to second reverse, second forward to second reverse, and second forward to first reverse. Auto-kickdown allows the transmission to automatically downshift when significant load increases are detected.
Instrument Panel and Cat Monitoring System
The instrument panel, with easy-to-read gauges and warning lamps, keeps the operator aware of all system information. All gauges and readouts are easily visible in direct sunlight. The Cat Monitoring System has a dash mounted instrument cluster showing on-the-go operating information and insight into operation and maintenance needs.
Integrated Electronic Solutions
AccuGrade System for Track-Type Tractors
The AccuGrade System automates blade control for greater grading accuracy and more cost effective operation. Machine-mounted sensors calculate precise blade slope and elevation, which is used by sensors to automatically adjust the blade to maintain grade. Automated blade control improves efficiency and productivity by reaching grade faster and in fewer passes, reducing the need for traditional survey stakes or grade checkers.
AccuGrade Ready Option
AccuGrade systems and controls can be integrated from the factory, making system installation and setup quick and easy. Integration also provides greater wear protection and reliability.
AccuGrade Laser
Laser signals from a transmitter on the work site are picked up by a machine mounted receiver to provide a constant grade reference. The system calculates blade adjustments to achieve grade, makes automatic elevation adjustments and provides automatic blade control. The operator simply steers the machine. The system also calculates cut/fill requirements for manual blade control.
AccuGrade GPS
Using global satellite-based positioning, AccuGrade GPS computes 3-dimensional positioning information on the machine, compares the position of the blade relative to the design plan, and delivers that information to the operator via an in-cab display.
Cat Product Link*
Cat Product Link allows remote monitoring of equipment to improve overall fleet-management effectiveness. Product Link is deeply integrated into machine systems. Events and diagnostic codes, as well as hours, fuel, idle time and other detailed information are transmitted to a secure web based application, VisionLink™. VisionLink includes powerful tools to convey information to users and dealers, including mapping, working and idle time, fuel level and more.* Product Link licensing not available in all areas. Please consult your Cat dealer for availability.
Undercarriage
Heavy Duty Undercarriage
Heavy duty undercarriage is well suited to aggressive applications like logging, side-slopes, or working in rocky or uneven terrain. Components are designed for extended wear life in abrasive conditions and high impact applications. Heavy duty track features improved track shoe design for enhanced penetration, increased leading and trailing edge of shoe and increased track overlap.
SystemOne™ Undercarriage
Optional SystemOne™ undercarriage can help reduce total undercarriage owning and operating costs in many applications. SystemOne features lifetime sealed and lubricated cartridges to completely eliminate the downtime associated to bushing turns, and sprockets require no replacement during the life of the chain. All SystemOne undercarriage components are designed to work and wear as a total system. Even wear in forward and reverse mean the machine is able to return to a forward push more quickly for overall better operator efficiency and improved productivity.
Track Shoes
Choose Moderate Service or Extreme Service track shoes to best match working conditions. The proper track shoes help reduce impact and wear for optimal undercarriage life – especially in high impact or highly abrasive conditions.
Work Tools
L-Shaped Push Arms
L-shaped push arms bring the blade closer to the machine than diagonal brace designs, providing excellent maneuverability, balance, and blade penetration. This design provides solid lateral stability and better cylinder positions for constant pryout independent of blade height.
Load Sensing Hydraulics
Field-proven, load-sensing hydraulics respond to operating requirements by automatically and continually adjusting hydraulic power to maximize work tool efficiency.
Cat Blades
Cat blades feature a strong box-section design, made from Cat DH-2™ 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.
Multi-Shank Ripper
The multi-shank parallelogram style ripper offers the choice of one, two, or three shanks. Choose curved or straight ripper shanks.
Winch
A single lever control actuates both clutch and brake functions to improve operator efficiency. See your Cat dealer for Winch options.
Rear Counterweight
Optimize balance for backing up steep slopes or increasing performance in heavy dozing applications. Rear counterweights are recommended on machine with standard tracks, and are required with VPAT blade if no rear attachment is specified.
Drawbar
The D6T can be equipped with a drawbar for retrieving other equipment or pulling work tools such as discs, compactors, or chopper wheels. Optional implement towing arrangements allow for quick setup of a hydraulically controlled towed scraper.
