Structures

Structures

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 - 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.

C18 Engine with ACERT Technology

C18 Engine with ACERT Technology

C18 ACERT - Performing at full-rated net power of 306 kW (410 hp), the large displacement and high torque rise allow the D9T to rip through tough material. Matched to the high-efficiency torque converter and electronically controlled power shift transmission, it will provide years of reliable service.
ADEM™ A4 Engine Controller - Manages fuel delivery for optimal performance per liter (gallon) of fuel used. Provides flexible fuel mapping, allowing the engine to respond quickly to application needs. Tracks conditions and keeps engine operating at peak efficiency.
Air-to-Air Aftercooling and Airflow - Air-to-air aftercooling keeps air intake temperatures down and, in concert with the tight tolerance combustion chamber components, maximizes fuel efficiency and minimizes emissions. Significant improvements in air flow are generated by a water-cooled turbocharger, unique cross-flow head and single overhead cam.
Fuel Heater (optional) - Uses the temperature of the engine coolant to warm the cold fuel coming directly from the tank. The fuel heater allows an easier transition to winter blended fuels during season changes.
High Altitude Arrangement (optional) - The attachment provides an updated turbo and control software that allows full tractor performance up to 4420 m (14,500 ft) altitude.

Cooling System

Cooling System

Aluminum Bar Plate Radiator – 6 Fins Per Inch (fpi) - Cooling system uses a radiator built with rugged, highly efficient aluminum bar plate cores. The aluminum bar plate construction aids durability and allows for higher heat transfer and superior corrosion resistance.
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 system, providing more power to the tracks to help you lower your cost per unit of material moved.
Attachments -
  • Reversing cooling fan for heavy debris applications with ultra low speed for cold weather.

Power Train

Power Train

The D9T power train design optimizes performance and the ease of operation helps customers get more done for the lowest cost per unit.
Torque Converter - A high efficiency torque converter with fixed stator provides high torque multiplication while shielding the drive train from sudden torque shocks and vibration.
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.
Bi-directional Shift - 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.
Auto Downshift - 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 -
  • Three speeds forward and three speeds reverse, utilizing large diameter, high capacity, oil-cooled clutches.
  • 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.

Undercarriage

Undercarriage

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.

Work Tools

Work Tools

Bulldozers - 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 Blade – Maximizes capacity for moving big loads over long distances.
  • Semi-Universal Blade – Built for tough applications where penetration is important.
  • Optional Dual Tilt – Allows the operator to optimize the blade pitch angle.
  • 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. For extremely severe applications, moldboard wear plates, extended wear life end bits and cutting edges are available.
  • 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 -
  • Single-Shank Ripper – Built for the tough ripping conditions and greater ripping depth. Operator can adjust the shank depth from the seat using an optional single-shank pin puller. Large one piece shank, available in deep rip configuration.
  • Multi-Shank Ripper – Generally for lighter duty ripping applications in less severe materials. Provides high levels of productivity. Tailors 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.

Operator Station

Operator Station

The D9T cab is designed and equipped for operator productivity, safety and comfort. The standard isolation-mounted cab reduces noise and vibration.

Benefits and Features

Structures

Structures

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 - 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.

C18 Engine with ACERT Technology

C18 Engine with ACERT Technology

C18 ACERT - Performing at full-rated net power of 306 kW (410 hp), the large displacement and high torque rise allow the D9T to rip through tough material. Matched to the high-efficiency torque converter and electronically controlled power shift transmission, it will provide years of reliable service.
ADEM™ A4 Engine Controller - Manages fuel delivery for optimal performance per liter (gallon) of fuel used. Provides flexible fuel mapping, allowing the engine to respond quickly to application needs. Tracks conditions and keeps engine operating at peak efficiency.
Air-to-Air Aftercooling and Airflow - Air-to-air aftercooling keeps air intake temperatures down and, in concert with the tight tolerance combustion chamber components, maximizes fuel efficiency and minimizes emissions. Significant improvements in air flow are generated by a water-cooled turbocharger, unique cross-flow head and single overhead cam.
Fuel Heater (optional) - Uses the temperature of the engine coolant to warm the cold fuel coming directly from the tank. The fuel heater allows an easier transition to winter blended fuels during season changes.
High Altitude Arrangement (optional) - The attachment provides an updated turbo and control software that allows full tractor performance up to 4420 m (14,500 ft) altitude.

Cooling System

Cooling System

Aluminum Bar Plate Radiator – 6 Fins Per Inch (fpi) - Cooling system uses a radiator built with rugged, highly efficient aluminum bar plate cores. The aluminum bar plate construction aids durability and allows for higher heat transfer and superior corrosion resistance.
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 system, providing more power to the tracks to help you lower your cost per unit of material moved.
Attachments -
  • Reversing cooling fan for heavy debris applications with ultra low speed for cold weather.

Power Train

Power Train

The D9T power train design optimizes performance and the ease of operation helps customers get more done for the lowest cost per unit.
Torque Converter - A high efficiency torque converter with fixed stator provides high torque multiplication while shielding the drive train from sudden torque shocks and vibration.
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.
Bi-directional Shift - 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.
Auto Downshift - 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 -
  • Three speeds forward and three speeds reverse, utilizing large diameter, high capacity, oil-cooled clutches.
  • 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.

Undercarriage

Undercarriage

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.

Work Tools

Work Tools

Bulldozers - 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 Blade – Maximizes capacity for moving big loads over long distances.
  • Semi-Universal Blade – Built for tough applications where penetration is important.
  • Optional Dual Tilt – Allows the operator to optimize the blade pitch angle.
  • 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. For extremely severe applications, moldboard wear plates, extended wear life end bits and cutting edges are available.
  • 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 -
  • Single-Shank Ripper – Built for the tough ripping conditions and greater ripping depth. Operator can adjust the shank depth from the seat using an optional single-shank pin puller. Large one piece shank, available in deep rip configuration.
  • Multi-Shank Ripper – Generally for lighter duty ripping applications in less severe materials. Provides high levels of productivity. Tailors 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.

Operator Station

Operator Station

The D9T cab is designed and equipped for operator productivity, safety and comfort. The standard isolation-mounted cab reduces noise and vibration. Overall operator sound levels have been reduced by 2 dB(A). Large windows, tapered hood, and notched fuel tank provide excellent visibility to all sides of the machine and around the job site.
The Advisor Monitoring System tracks machine operating conditions in real time.
