These models include safety enhancements, improved operator comfort, and productivity increasing electronic features to keep your business strong for generations to come.
Engineered for maximum production and service life.
Helping you get more done with maximum availability, the durable design of the mainframe makes repair and maintenance easy. 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.
Proper grease lubrication on working surfaces can significantly extend component life and help lower maintenance cost.
The Carrydozer frame is specifically designed to accept the additional frame loads generated by the unique Carrydozer blade design.
Power and reliability to help you move more.
The Cat C32 engine with ACERT Technology delivers power and reliability, ensuring top performance, high productivity, and exceptional service life.
The ADEM A4 electronic control module manages fuel delivery and air flow to get the best performance per liter (gallon) of fuel used.
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.
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.
Providing you reliable, integrated solutions.
The D11T/D11T CD’s C32 engine with ACERT Technology will meet Tier 4 Final emission standards and will be required for sale in higher regulated countries.
The D11T/D11T CD meets Tier 4 Final emission standards using:
Superior cooling keeps you moving 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 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.
Copper cores improve cooling efficiency making our radiator a good choice for high ambient temperature environments and heavy debris applications. The cooling tubes are oriented to allow open passages for dirt and debris to blow through the core. It is standard on Tier 4 Final machines – optional on other configurations.
The new hydraulic oil to air cooler reduces hydraulic oil temperatures improving component durability and reliability.
Power and control to efficiently move your material.
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 power train by dampening impact loads and vibrations.
Three speeds forward and three speeds reverse, utilizing large diameter, high-capacity, oil-cooled clutches.
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. Steering clutches, brakes and final drives can be removed as a unit from each side of the tractor.
Designed for optimized machine balance and performance at your site.
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.
Designed for your comfort, convenience, and productivity.
The D11T/D11T CD cab provides ergonomic controls, intuitive monitoring systems, and enhanced visibility. All of these features provide the D11T and D11T CD an industry leading operator environment that helps contribute to high levels of productivity, efficiency, and comfort.
Additional features include:
The Finger Tip Controls (FTC) require less effort and are more comfortable for long periods of operation. Electronic controls eliminate direct mechanical connections to the power train, resulting in reduced noise and vibration inside the cab.
Low effort and comfortable to grip, the electronic dozer joystick gives the operator control of all dozer functions with the right hand.
A rigidly mounted handgrip on the electronic ripper control provides firm support for the operator even when ripping in the roughest terrain. Low effort thumb lever controls raising and lowering.
Monitor, manage, and enhance job site operations.
The D11T electronic systems have been completely integrated to function as one machine. This integration creates a smart machine and more informed operator maximizing the productivity of both.
Configurable to suit your operation’s needs.
Cat MineStar helps you manage everything from material tracking to sophisticated real-time fleet management, machine health systems, autonomous equipment systems and more. The capability sets: Fleet, Terrain, Detect, Health and Command can be used in combination or individually to allow your operation the flexibility and scalability it needs to be more productive, efficient and safe.
Focused on keeping you safe.
Safety is Caterpillar’s top priority. We constantly enhance product design and engineering to support customer safety goals and create safe working environments.
This feature locks out the power train and hydraulics under certain conditions to prevent unintentional movement when the operator is not in the seat.
Strategically placed grab handles plus non-slip steps and decking aid operator getting on and off the machine.
Standard heavy duty guard rails are strategically placed to safeguard the operator outside of the cab.
The D11T offers three options to control operator and spectator sound levels. Options include:
Anchorage points provide your people with a positioning system to preform repairs and maintenance. The D11T/D11T CD consist of fourteen (14) total anchorage points.
This feature provides access to the lift cylinders for cleaning or repairing the mounted mirrors and lights.
The Cat powered access system provides excellent access and egress to and from the cab on the D11T/D11T CD, allowing easy access even in wet or freezing conditions.
The platform provides access to the rear window for cleaning and repairing rear mounted lights. The walkway is a modular design so varying lengths can be used across the back of the tractor to meet unique customer needs.
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. Heavy moldboard construction and hardened bolt-on cutting edges and end bits add strength and durability.
Rippers are made to penetrate tough material fast and rip thoroughly for use in a variety of materials.
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. It is recommended if not equipped with any other rear attachment.
Reduce your service time to increase your uptime.
The modular design of the D11T provides excellent serviceability and turnaround time. A key advantage of the D11T’s modular design is the ability to swap out a component with a pre-tested rebuilt or remanufactured unit that puts the machine back to work faster. So, reliability and overall uptime is high, repairs and upkeep costs are low. Modular design translates into more time on the job for the D11T compared to competition.
The ground level service center mounted on the ripper cylinder or counterweight provides easy access to:
The Ok-to-Start strategy provides electronic fluid level verification at startup on the power train and engine oil systems. All information is available via the Advisor Monitoring System within the cab.
The fast fuel system, with positive fuel shut-off to prevent fuel spillage, can reduce fuel waste and decrease downtime.
