Structures

Engineered for maximum production and service life.
Mainframe Strength
We help reduce downtime by making our machines easy to repair and maintain. The D11T/D11T CD mainframes are built to absorb high impact shock loads and twisting forces during severe dozing and ripping applications. It is not uncommon to see these machines rebuilt several times using the same frame, with only minor welding.
  • Frame rails have a full box section design which keeps components rigidly aligned.
  • 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 to eliminate welds and machining, which provide 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 one-piece main case casting also serves as an oil reservoir.
  • The pivot shaft and pinned equalizer bar maintain track roller frame alignment.
  • Heavy cast saddle has a ribbed design which increases frame life.
  • The common front engine and radiator mount feature heavy steel castings.
Carrydozer Frame
The Carrydozer frame is specifically designed to accept the additional frame loads generated by the unique Carrydozer blade design.
Tag-Link
The tag link is designed to increase blade penetration and pry-out force as well as increase machine maneuverability and balance. The closer the blade is kept to the machine, the easier it is for the operator to maneuver near obstacles. Keeping the blade closer to the machine also reduces the lever effect on machine balance, especially when working around high-walls, affording the operator increased confidence.
  • A tag link replaces the diagonal bracing because dozer side loads are transferred directly into the specially reinforced mainframe instead of the dozer push arms.
  • The Cat design with almost vertical motion of the lift cylinders allows maximum machine weight to be transferred to the blade’s cutting edges. This extra force increases blade cutting edge penetration and improves blade loading.

Engine

Power and reliability to help you move more.
C32 with ACERT Technology
Designed to deliver the performance and maximum fuel efficiency you demand, the D11T/D11T CD features a Cat C32 ACERT engine.
  • The C32 performs at full rated net power of 634 kW (850 hp) at 1,800 rpm with a high torque rise of 21 percent, allowing the D11T to doze through tough material.
  • Matched to the high efficiency torque divider and electronically controlled power shift transmission, it will provide years of dependable service.
ADEM™ A4 Engine Controller
The ADEM A4 electronic control module manages fuel delivery and air flow to get the best performance per liter (gallon) of fuel used. • Provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs.
Air-to-Air Aftercooling
Air-to-air aftercooling on the D11T/D11T CD cools hot, compressed air coming out of the turbocharger providing cooler and denser air into the air intake system. Bringing more cool air into the engine increases power generation, lowers emissions, and improves fuel efficiency.
Service
Engine enclosures provide easy access to maintenance points within the engine compartment. Easier maintenance and repair is available through monitoring of key functions and logging of critical indicators.

Cooling System

Superior cooling in the most demanding work conditions.
The hydraulic variable demand fan provides engine cooling capability that is matched to the ambient conditions. In cooler conditions, the fan turns at a slower speed, reducing power demands. This reduces fuel consumption in lower load factor operations. Low speed fan operation also reduces both the operator and spectator sound levels.
Aluminum Bar Plate Radiator
The cooling system uses a two-part 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 Air to Oil Cooler
The new air to hydraulic oil cooler reduces hydraulic oil temperatures thus improving component life. The core is built using the same rugged aluminum bar plate design as the jacket water cooler.
Attachments
  • Reversible cooling fan
  • Mesabi radiator

Drive Train

Power and control to efficiently move your material.
Torque Divider
The Cat D11T/D11T CD use a torque divider between the engine and the transmission to act as the hydrodynamic component, reducing the possibility of damage to the powertrain by dampening impact loads and vibrations. • A single-stage torque converter with output torque divider sends 75 percent of engine torque through the converter and 25 percent through a direct drive shaft for greater driveline efficiency and higher torque multiplication.
Planetary Powershift Transmission
The Cat Planetary Powershift Transmission offers three speeds forward and three speeds reverse, utilizing large diameter, high-capacity, oil-cooled clutches.
  • Modulation system permits fast speed and direction changes.
  • Modular transmission and bevel gear slide into rear case for easy servicing, even with ripper installed.
  • Oil-to-water cooler for maximum cooling capacity.
  • Forced oil flow lubricates and cools clutch packs to provide maximum clutch life.
  • Controlled throttle shifting regulates engine speed during directional shifts for smoother operation and longer component life.
Steering Clutch and Brake
Fade resistant and adjustment free. The multi-disc, oil cooled steering clutches are hydraulically applied and electronically controlled. The brakes are applied by springs and hydraulically released for safe and reliable braking performance.

Undercarriage

Designed for optimized machine balance and best performance.
The elevated sprocket and suspended undercarriage work together, increasing traction and giving the operator a smoother ride. These benefits translate into higher production and longer component life. This design transfers implement shock loads to the mainframe, so final drives, axles, and steering components are isolated from harsh impact loads commonly seen in large track-type tractor applications.
  • Bogie suspension provides up to 15 percent more ground contact, especially in hard, uneven terrain. Higher traction means less slippage, better balance, and a smoother ride.
  • Integrated carrier roller mount is fabricated into the track roller frame making it easy to add the optional carrier roller in the field.
  • Rollers and idlers feature symmetric Duo-Cone™ seals for long sealing life to prevent oil loss and dirt entry.
  • Roller frames are tubular to resist bending and twisting, with added reinforcement.
  • Sleeve bearing track is a unique track link assembly that maximizes life and minimizes downtime. It is designed to operate at higher speeds and greater loads.
  • Sprocket segments have four bolt-on replaceable rim segments of abrasion resistant tough steel for long wear life.
  • Track shoes are available in a variety of sizes and styles to match working conditions.

Operator Station

Designed for your comfort, convenience, and productivity.
The D11T/D11T CD cab is designed and equipped for operator productivity, safety, and comfort. Electro-hydraulic controls require low effort to control steering and implements. This helps to reduce operator fatigue and to improve productivity. The monitoring system display, with easy-to-read gauges, indicators and warning lamps, keeps the operator aware of machine conditions. All of these features provide the D11T and D11T CD an industry leading operator environment that provides high productivity, efficiency, and comfort.
  • The operator station offers an exceptional viewing area. The tapered hood, notched fuel tank, and narrow ripper carriage give the operator a clear line of sight to front and rear work areas. The laminated glass door windows provide an excellent view to the blade end bits.
  • The new automatic climate control system automatically adjusts the heating and air conditioning controls to maintain a consistent cab temperature throughout the day.
  • The Cat Comfort Series Seat has a six way adjustment control for optimal support and comfort. Seat side bolsters restrain side‑to-side movement, especially when working on steep grades or side slopes.
  • The combination dash mounted instrument cluster and the right console mounted Advisor Monitoring System display key machine operating information and give operators and service technicians insight into the machine’s operation and maintenance needs.
  • Dimmable lights allow the operator to choose between night and day backlight settings, through Advisor, to adjust the brightness of all switches and the keypad in the cab.
