D6N WH Waste Handler

The Cat Track-Type Tractor waste handling arrangement machines are purpose built for landfill operations. Special guarding and cooling systems are standard on these machines to help them withstand the harsh operating conditions in the landfill.

Waste Handling Guards



Extensive guarding helps protect critical machine components, body panels and the cooling system from being damaged by debris under harsh waste handling environments.

HeavyDuty Bottom Guards



The bottom guards serve a dual purpose. They help prevent damage to vital powertrain components, and keep debris out of the powertrain compartments.

HeavyDuty Fenders



The fenders on the Waste Handling Arrangement are twice as thick as the standard fenders. Their design protects the edge of the sheet metal above the fender. The heavier fenders are able to better resist bending while working in a landfill application.

HeavyDuty Battery Box



The steel on the battery box cover is thicker, compared to the thickness for the standard machine. This allows resistance to denting while working in a landfill.

HeavyDuty Hinged Radiator Grille



The heavyduty hinged radiator grille protects the cooling system. The grille is an angled plate type grille, hinged for easier access. The 45 angle of the bars diverts airflow up and away from the back of the dozer blade. Helps keep debris from damaging the radiator.

Idler Seal Guards



The idler seal guards help keep wire, fishing line, strapping, etc., from wrapping around and damaging the ideler seals.

Final Drive Seal Guards



The final drive seal guards help prevent wire, nylon strapping, etc., from wrapping around and damaging the DuoCone seals. The outer guard is now stationary, thicker, and has increased hardness, all of which help prevent excessive wear from debris.

Seal Guard Design



This design offers superior protection to the seal. Debris would have to make four 90 turns, penetrate the packing material, and then make two additional 90 turns.

Lift Cylinder Lines Guard



Helps protect lift cylinder hoses and tubes from debris damage.

Debris Resistant Features



A variety of debris environment features is included with the Waste Handling Arrangement to reduce plugging, extend service life, and enhance productivity.

Rear, Tankmounted Lights



The rear, tankmounted lights are relocated on the ROPS, which removes the lights from the concentrated debris environment to help protect them from damage. Combinations vary depending on each model.

Front Lights



The front lights are mounted between the top of the bulldozer fenders opening to the top of the cylinders, allowing them to project light over the trash rack and keep the lights above the concentrated debris environment for longer service life.

Raised Prescreener



Raised prescreener helps reduce the likelihood of airborne paper or plastics plugging the air intake. It provides a larger air inlet. Part of standard waste handling modification when turbine precleaner is not ordered.

Heavyduty Steps and Handles



The heavyduty steps and handles are manufactured from plate steel and solid rod to withstand the rigors of landfill operation.

HeavyDuty Latches



On sheet metal access panels and engine enclosures.

Highcapacity Alternator



The highcapacity 100amp alternator provides additional power required for electrical accessories such as supplemental lights and communications and entertainment radios. The debris shield helps prevent debris from entering into the alternator.

Required Attachments



These attachments must be ordered in addition to the basic Waste Handling Arrangement.

Clamshell Guards



The clamshell guard provides a nonrotating guard installed over the final drives to help prevent wire wrap. The guard includes inspection plates.

Ejector Fan



The ejector fan blade is designed with curved edges to help throw debris out radially. This helps prevent debris from clogging the radiator.

Flexxaire Fan Engine Control System



The Flexxaire fan engine control system automatically reverses fan pitch at preset intervals to purge debris from the radiator and engine compartment. The operator also can manually purge the fan at any time. The Flexxaire fan is controlled by the engine ECM Electrical Control Module.

Radiator AMOCS



The AMOCS radiator utilizes an exclusive two pass cooling system and increased cooling surface area to provide significantly more cooling capacity than conventional systems. A trash core radiator is available with six fins per inch, replacing the standard nine fins per inch.

Laminated Thermal Shields



The laminated thermal shields cover the exhaust stack inside the compartment, hotside of the turbocharger, and the exhaust manifold. These shields reduce surface temperatures well below the flash point of most common combustibles encountered.

HeavyDuty Engine Enclosures



The engine enclosures consist of perforated hood and side panels. A vertical hinge allows the doors to swing open horizontally for serviceability access. The enclosures help prevent airborne materials from entering the engine compartment and help reduce radiator plugging, which can cause cooling system problems. Note If the sound suppression arrangement is ordered, the perforated side panels are replaced with solid doors and the perforated hood is replaced with larger rectangular perforations.

Hydraulic and Fuel Tank Guard



The hydraulic and fuel guard helps protect implement hydraulic oil tank, fuel tank, and battery box. ulli The hydraulic tank guard includes a hinged cover to protect the filter housing and fill spout.lili The fuel tank guard is 10 mm .375 in thick compared to others at 6 mm .25 in thick. Incorporated in the tank guard is a fill cap guard.lili The heavier steel helps make the fender area structurally stronger, allowing the fenders to resist bending.liul

Recommended Options



Features for peak performance. Several additional options are recommended to assist in matching your site requirements.

Tilt Cylinder Lines Guards



The optional tilt cylinder lines guards help protect hydraulic lines from contact damage, while maintaining hose flexibility.

Rear Striker Bars



The optional rear striker bars incorporate a rigid drawbar and housing with large access doors for storage on machines not equipped with rippers. The rear striker bars are counterweightready in case additional rear weight is needed. For machines with rippers, striker bars mount on ripper frame.

Caterpillar Landfill Blades



The Caterpillar landfill blades increase the dozing capacity in trash and help prevent material from spilling over the blade and entering the radiator. Wear plates are available and are recommended when working in highly abrasive materials.

Front Striker Bars



The front striker bars angled design prevents debris from riding up the track and damaging the fenders or fuel and hydraulic tanks.

Trapezoidal Hole Track Shoes



The trapezoidal hole track shoes reduce refuse packing within the track and reduces track chain tightening and accelerated pin and bushing wear. The trapezoidal holes relieve packing by allowing the sprocket to punch out dirt and debris.

Black Painted Hood, Cylinders, and Back of Blade



The black painted hood, cylinders, and back of blade reduces glare from lights while operating at night and while operating in direct sunlight.

Hydraulic Rippers



Hydraulic rippers are available as single or multishank to penetrate tough material fast and rip thoroughly.

Differential Steering System



Differential Steering maintains power to both tracks while turning. Operator controls machine speed, direction and steering with the tiller bar controller, while maximizing production.

Undercarriage



Elevated sprocket design isolates the final drives from ground induced impacts for excellent component life. The XL or the LGP configurations allow you to match the machine to your specific application.

Serviceability



Cat elevated sprocket tractors use a new generation modular design that simplifies service and repair. Easy maintenance and fast infield component exchange gives you more time on the job.

Builtin Servicing Ease



Less service time computes to more production time. Major components are made as modules and most can be removed without disturbing or removing others.

Grouped Service Points



Grouped service points and easy access to servicing areas make routine inspections fast and convenient.

Quick Disconnect Fittings
