The Carrydozer frame is specifically designed to accept the additional frame loads generated by the unique Carrydozer blade design.
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.
The D11T/D11T CD's C32 engine with ACERT Technology will be capable of achieving levels equivalent to Tier 2 equivalent emission standards for lesser or non-regulated countries.
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.
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. It is only available on D11's with Tier 2 equivalent emission standards.
Copper cores improve cooling efficiency making the Mesabi 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 optional on Tier 2 equivalent configurations.
The new hydraulic oil to air cooler reduces hydraulic oil temperatures improving component durability and reliability.
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.
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.
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.
This feature provides access to the lift cylinders for cleaning or repairing the mounted mirrors and lights.
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.
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 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.
