Cat D9T WH Waste Handler

The Diesel Particulate Filter can provide a particulate reduction of greater than 90%. It filters soot from the exhaust. Soot is then removed through the regeneration process automatically or manually.

Diesel Exhaust Fluid is a liquid that is injected into the exhaust system of engines equipped with Selective Catalytic Reduction (SCR) systems. On the D9T the DEF tank is located on the left hand fender enclosure next to the fuel tank. Diesel Exhaust Fluid that meets ISO 22241 specifications is required.

Air-to-air aftercooling on the D9T cools hot, compressed air coming out of the turbocharger providing cooler and denser air for the air intake system. Bringing more cool air into the engine increases power generation, lowers emissions, and improves fuel efficiency.

Customers experience increases in production and fuel economy as well as reductions in fan noise and engine overcooling with the closed circuit 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 systems, providing more power to the tracks to help you lower your cost per unit of material moved.

The power shift transmission and differential steering work with the C18 ACERT engine to deliver the outstanding power, productive performance and reliability expected from Cat Large Dozers. Differential steering maintains full power to both tracks to provide best-in-class turning with a loaded blade. When one track speeds up, the other slows down an equal amount. Maneuverability – especially with large blade loads – is improved, as well as cycle times in some applications. Greater load capacity, power and speed control are possible in soft underfoot conditions on steep slopes.

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.

Cat Waste Handlers are designed with guarding and seals that are critical to the life of your investment and keeping the D9T productive in this application.

• Hinged cleanout slot covers offer quick access to the front side of the radiator cores for cleaning.
• Engine enclosures have perforated hood and side panels to help prevent airborne debris from entering the engine compartment and helps reduce radiator plugging.
• Turbine Engine Precleaner and Dust Ejector delivers clean air and provides longer filter life. The intake air is spun by a flow driven impeller. Debris stratifies along the outer wall and is ejected back into the environment, allowing only precleaned air to continue to the engine's air filter.
• High-capacity ducted alternator provides additional power required for electrical accessories. Ducting is provided that helps prevent debris from entering into the alternator for longer life.
• Sealed Bottom Guards* help protect against contact damage and help keep debris out of vital machine compartments.
• Clamshell Guards* are designed to optimize performance in waste handling applications. Using clamshell guards with inspection covers will protect the final drive seal from damage due to winding of wire, nylon strapping, fishing line, etc.
• D9T Waste Handling Undercarriage* includes guarded idlers and guarded pivot shaft seal, and front track roller frames that can accept front striker bars.
• Standard operator controls and platform with quick opening floor plates* to aid in regular cleaning.
• Wrapped exhaust* includes steel covered, insulated exhaust shields for the exhaust manifolds, turbo and muffler inlet tube.

*Required for Waste Handling Arrangement.

A number of optional features are recommended to help customers get optimal performance from their D9T Waste Handler.

• Cat landfill blades increase the dozing capacity in trash and help prevent material from spilling over the blade and entering the radiator.
• Front striker bars angled design helps prevent debris from riding up the track during tractor reversal to prevent material from damaging the fenders or fuel and hydraulic tanks.
• Rear striker bar includes a striker bar, storage box, drawbar, three slab counterweight, fast fuel system, and transmission guard. The bar is used to knock material off of the tracks during forward operation to prevent material from packing between the track and fender.
• Trapezoidal hole track shoes help extends service life by reducing refuse packing within the track. The trapezoidal hole design allows the sprocket to punch out most dirt and debris help extend track pin life.
• Powered cab air precleaner includes an additional centrifugal precleaner to separate excess dust particles before the air enters the cab fresh air filter extending filter life.
• Guarding helps protect implement hydraulic oil tank, DEF tank (serial prefix REX) and fuel tank in high debris landfill applications.
• Tilt cylinder lines guard helps protect hydraulic lines from contact damage, while maintaining hose flexibility.
• Halogen, HID or LED lights are mounted up and away from the concentrated debris environment for excellent illumination for optimum visibility under low light conditions.

Cat Grade Control for dozers is an integrated electronic system that works in landfill applications to ensure the correct amount of material is moved. This helps conserve valuable airspace and cover soil with reduced stakes and crews. The system uses dual ROPS mounted Global Navigation Satellite System (GNSS) antennas and in-cylinder position sensors to provide precise positioning of the cutting edge. This eliminates the need for masts and cables on the blade and improves visibility for the operator. As compared to traditional aftermarket externally mounted sensors, the Cat Grade Control sensors are protected from the harsh working environments in the landfill. Additionally, Cat Grade Control 3D permits the identification of site specific storage areas such as hazardous waste, medical, industrial, organic, and other materials which require special handling or a record of their placement.

AccuGrade is a dealer-installed aftermarket grade control system that provides higher accuracy capabilities by adding laser and GPS technology when required. The factory AccuGrade Ready Option provides optimal mounting locations, brackets, and hardware and simplifies installation. Deep integration optimizes machine and system performance to maximize productivity.
