Engineered for maximum production and service life.
Mainframe Strength - Built to Last
Helping you get more done with maximum availability, the D9T’s durable design makes repair and maintenance easy. Customers can rebuild these tractors several times using the same frame with only minor repairs. With unparalleled support from Cat dealers it is not unusual for a Cat large dozer to log more than 100,000 hours.
- The D9T mainframes are built to absorb high impact shock loads and twisting forces encountered during severe dozing and ripping applications.
- The main case, equalizer bar saddle, and front cross member are heavy duty steel castings incorporated into highly loaded areas of the mainframe to improve stress distribution for improved durability.
- Top and bottom rails are made from continuous rolled sections providing superior mainframe durability.
- The main case elevates the final drives well above the ground level work area to protect them from impact loads, abrasion and contaminants.
- The pivot shaft and pinned equalizer bar maintain track roller frame alignment and allow the roller frame to oscillate for smoother ride.
Tag-Link blade mounting brings the blade closer to the machine for excellent maneuverability, machine balance and blade penetration. This design also eliminates the need for diagonal bracing by transferring side loads to the mainframe, instead of the dozer push arms.
Equalizer Bar End Pins
Proper grease lubrication on working surfaces can significantly extend component life and help lower maintenance cost. • Remote lubrication is performed from a service point conveniently located on the left hand side of the engine compartment and allows an operator or service technician to lubricate both the left-hand and right-hand equalizer bar end pin bearings and pins from one service point.
Power and reliability to help you move more.
C18 with ACERT Technology
The C18 ACERT engine meets Tier 4 Final and Stage IV emission standards and delivers power, reliability, high productivity, and exceptional service life.
- The C18 ACERT engine performs at full rated net power (SAE J1349/ISO 9249) of 325 kW (436 hp) at 1,800 rpm with a high torque rise of 36 percent, allowing the D9T to power through tough material.
Cat NOx Reduction System (NRS)
The Cat NOx Reduction System captures and cools a small quantity of exhaust gas, then routes it into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.
Diesel Particulate Filter (DPF)
The Diesel Particulate Filter can provide a particulate reduction of greater than 90%. It filters soot from the exhaust. Soot is then removed through the regeneration process automatically or manually.
Selective Catalytic Reduction (SCR)
The Selective Catalytic Reduction system can provide a NOx reduction of greater than 90%. SCR operation is transparent to the operator during operation. The urea solution, Diesel Exhaust Fluid (DEF), is pumped from the DEF tank and is sprayed into the exhaust stream. The DEF reacts with the SCR catalyst to reduce NOx.
Diesel Exhaust Fluid (DEF)
Diesel Exhaust Fluid is a liquid that is injected into the exhaust system of engines equipped with Selective Catalytic Reduction (SCR) systems. On the D9T the DEF tank is located on the left hand fender enclosure next to the fuel tank. Diesel Exhaust Fluid that meets ISO-22241 specifications is required.
Superior cooling keeps you moving in the most demanding work conditions.
The D9T provides durable, efficient cooling for the most demanding conditions encountered on job sites.
Aluminum Bar Plate Radiator - 6 Fins Per Inch (fpi)
The radiator core design is wider, deeper, and integrates tanks with the cores. This extremely durable design supports higher heat transfer and provides superior corrosion resistance.
Air-to-air aftercooling on the D9T cools hot, compressed air coming out of the turbocharger providing cooler and denser air for the air intake system. Bringing more cool air into the engine increases power generation, lowers emissions, and improves fuel efficiency.
Hydraulic Oil to Air Cooler
Helping to save on repair and maintenance costs, the oil to air hydraulic cooler helps extend component life by reducing hydraulic oil temperatures.
Hydraulically Variable, Demand Fan
Customers experience increased production and fuel economy as well as reductions in fan noise and engine over cooling with the hydraulically variable demand fan. The demand fan changes speed to match ambient conditions. In cooler environments, the fan turns at a slower speed; consuming only the power required to cool the tractor systems, providing more power to the tracks to help you lower your cost per unit of material moved.
Reversing cooling fan for heavy debris applications with ultra low speed for cold weather.
Power and control to efficiently move your material.
The D9T power train design optimizes performance and the ease of operation helps customers get more done for the lowest cost per unit.
Advanced Productivity Electronic Control System (APECS)
Is a key contributor to improved speed shift performance and quality in the D9T. The operator will notice enhanced comfort during speed shifting resulting in an increased level of operator productivity. Most importantly, the improved shift quality provided by APECS is a key enabler to obtaining the full benefits of Enhanced AutoShift (EAS).
Enhanced Autoshift (EAS)
A standard feature for the D9T is EAS. EAS improves fuel efficiency and productivity by automatically selecting the optimal gear and engine speed combination based upon power train load and desired ground speed. This feature functions similar to an automatic transmission.
This convenience feature helps reduce operator work load during operation. Bi-directional shift allows the operator, by just making a directional change, to automatically select the desired forward and reverse gears or the desired forward and reverse speeds when EAS is activated.
This feature adds value by enhancing safety and productivity during the dozing cycle. When not in EAS mode, auto downshift can be used to automatically downshift the transmission when significant load increases are detected, but this feature will not automatically up-shift when load is reduced. Auto downshift provides optimal performance with minimal operator effort. The operator may override these automatic shift features at any time.
High Availability Is Key
Major power train components are modular in design, so being able to quickly remove and reinstall a new pre-tested component gives you the ability to keep the dozer up and running and producing.
Planetary Powershift Transmission
- Transmission controls permit smooth speed and direction changes with Advanced Productivity Electronic Control System (APECS).
- Oil-to-water cooler for maximum cooling capacity.
- Forced oil flow lubricates and cools clutch packs to provide maximum clutch life.
- Modular transmission and bevel gear slide into rear case for easy servicing, even with ripper installed.
Power Turn with Differential Steering
With differential steering, large blade loads can be smoothly maneuvered throughout a turn.
- Differential steering has the ability to work in tight areas by providing a tight turning radius.
- Differential steering maintains a high ground speed while turning keeping productivity high.
Designed for optimized machine balance and best performance at your site.
The elevated sprocket and fully suspended undercarriage work together, increasing traction while creating a smoother ride for your operators. The elevated sprocket design transfers implement shock loads to the mainframe, so final drives, axles and steering components are isolated from harsh impacts. These benefits translate into higher production and longer component life.
- Bogie Suspension allows the track to conform to ground condition, providing up to 15% more ground contact, especially in hard, uneven terrain. Higher traction means less slippage, better balance, and a smoother ride.
- Roller frames are tubular to resist bending and twisting, with added reinforcement where operating loads are highest.
- The undercarriage idler guard provides additional wear protection from abrasive material to the moving undercarriage. Includes rubber idler protectors.
- Positive Pin Retention (PPR) sealed and lubricated track is designed for high-impact and high load applications. The Caterpillar design locks the link to the pin reducing the opportunity for premature loss of lubrication. Sealed design permanently coats the track pin with lubricant, minimizing metal-to-metal contact and virtually eliminating internal pin and bushing wear.
Provide flexibility to match the machine to your job.
All blades feature a strong box-section design that resists twisting and cracking. Blades are made of high tensile strength steel that stands up to the most demanding applications.
- High-Capacity Universal Blades - Offers optimal capacity for moving big loads over long distances.
- Semi-Universal Blades - Built for tough applications where penetration is important.
- Cutting Edges and End Bits - Cutting edges are made of DH-2™ steel. End bits are made of DH-3™ steel for maximum service life in tough materials.
- Dual Tilt (optional) - Improves load control and allows the operator to optimize blade pitch angle.
- Cat Work Tools offer a range of special application blades, including coal stockpile blade, landfill blade, cushion dozer blade, reclamation blades and wood chip blade.
Rippers are made to penetrate tough material fast and rip thoroughly for use in a variety of materials.
- Single-Shank Ripper - Operator can adjust the shank depth from the seat using an optional single-shank pin puller.
- Multi-Shank Ripper - Tailor the tractor to the material by using one, two or three shanks.
CapSure™ Hammerless Ripper Tip and Shank Protector Retention System
The tip and shank protector are easily installed with a 180 degree turn of a ¾ inch ratchet. This simple installation means no hammering and therefore improved safety. It also means quicker change outs and less downtime.
Rear counterweights provide proper tractor balance to maximize dozing production. Recommended if dozer is not equipped with any other rear attachment.
Designed for your comfort, convenience, and productivity.
The D9T’s cab design provides ergonomic controls, intuitive monitoring systems, and enhanced visibility. All of the new features within the D9T operator station provide an industry leading operator environment that helps contribute to high levels productivity, efficiency, and comfort.
Standard machine provides 76 dB(A) for North America operator noise levels. Lower sound levels are available if optional sound suppression packages are installed. Cat Optimized Seat has six way adjustment control for optimal support and comfort. Seat side bolsters restrain side-to-side movement, especially when working on side slopes. The automatic climate control system automatically adjusts the heating and air conditioning controls to maintain a consistent cab temperature throughout the day.
Wide Panoramic View
For enhanced safety and production, the operator station offers an exceptional viewing area. The tapered hood, notched fuel tank, and narrow ripper carriage gives the operator a clear line of sight to front and rear work areas.
The multi-color/touch screen display located at the front of the right hand console is the operator’s gateway to monitoring machine performance and a convenient way of modifying machine parameters to tailor performance to the current task. The Information Display screen is larger, faster, and more powerful with increased memory and intuitive menu structure. The Work Monitor screen within the Information Display collects machine data and provides real-time feedback on machine performance to optimize productivity.
Implement and Steering Controls
The D9T utilizes electro-hydraulically controlled differential steering, which helps keep power to both tracks for constant centerline velocity for higher productivity in applications with a lot of turning. Also allows for counterrotation of tracks. This steering system combines the direction and degree of turns, forward-reverse shifting, and gear selection in a single control handle, to enhance operator comfort and help reduce fatigue. A low-effort electronic dozer control handle gives the operator complete control of all dozer functions with one hand. The ripper control handle is located to the operator’s right, directly behind the dozer joystick. A rigidly mounted hand grip provides firm support for the operator even when ripping in the roughest terrain.
