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.
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.
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 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.
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.
The attachment provides an updated turbo and control software that allows full tractor performance up to 4420 m (14,500 ft) altitude.
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.
Helping to save on repair and maintenance costs, the oil to air hydraulic cooler helps extend component life by reducing hydraulic oil temperatures.
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.
The D9T power train design optimizes performance and the ease of operation helps customers get more done for the lowest cost per unit.
A high efficiency torque converter with fixed stator provides high torque multiplication while shielding the drive train from sudden torque shocks and vibration.
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.
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.
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.
Provide proper tractor balance to maximize dozing production. Recommended if dozer is not equipped with any other rear attachment.
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.
Operators will enjoy comfort features like standard Cat Optimized Seat, adjustable arm rests and automatic climate control. The climate control system automatically adjusts heater and air conditioning controls to maintain a consistent cab temperature throughout the day. Both heater and air conditioner deliver filtered, pressurized, temperature controlled air to the operator and/or windows. The system performs five functions: heating, cooling, defrosting, pressurizing and defogging.
This feature locks out the power train and hydraulics 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 aid the operator outside the cab.
You will benefit from high uptime and lower upkeep costs with the reliable D9T. The modular design supports efficient servicing and quick turnaround on repairs. Through the ability to swap out a component with a pretested rebuilt or remanufactured unit, the D9T returns to the job faster.
Minimizes maintenance and repair downtime. Sight gauges, filter locations, improved access to oil and coolant sampling ports, and an engine compartment mounted work lamp, make daily and periodic service faster and easier.
The Ok-to-Start strategy provides electronic fluid level verification at startup on the engine coolant, engine oil and power train oil systems. All information is available via the Advisor Display within the cab.
The fast fuel system at ground level, with positive fuel shut-off to prevent fuel spillage, can reduce fuel waste and decrease downtime.
This system gathers historical trends, histograms, events and more through a wired connection for off-board analysis in applications such as VIMS PC. Additional subscription is required.
Product Link enables the remote transmission of information about the location, operation, and condition of your equipment. Efficiently and effectively monitor performance of your assets to help keep your jobs on schedule, maintain equipment condition, and reduce the costs of owning and operating your fleet.
