Waste Handling ArrangementExtensive guarding helps protect critical machine components, body panels and the radiator from being damaged by debris. Minimizing build-up helps prevent component damage.
Hinged radiator guardThe hinged radiator guard protects the cooling system. It comes equipped with two quick release "T" handles for the center opening guard, allowing easy access to the radiator for cleaning. Covers protect the handles from damage. Special hinge latches retain the guard in the open or closed positions.
Tilt cylinder line guardsThe tilt cylinder line guards help protect hydraulic lines from contact damage, wile maintaining hose flexibility.
Crankcase (belly) guardsThe crankcase (belly) guards serve a dual purpose. They help prevent contact damage to vital power train components, and help keep debris out of the power train compartments.
Chassis guardsThe chassis guards help protect the engine compartment by deflecting debris from rising upward along the chassis.
Pivot shaft seal guardsThe pivot shaft seal guards help prevent debris from entering and damaging the Duo-Cone seals as well as the bolts on the pivot shaft seals retainers.
Idler seal guardsThe idler seal guards help keep wire, fishing, fishing line, strapping, etc., from wrapping around and damaging the Duo-Cone seals.
Final drive seal guardsThe final drive seal guards help prevent wire, nylon strapping, etc., from wrapping around and damaging the Duo-Cone seals. The outer guard is now stationary, thicker, and has increased hardness, all of which help prevent excessive wear from debris.
Debris Resistant FeaturesAdditional landfill modifications enhance productivity and help prevent damage.
Rear, tank-mounted lightsThe rear, tank-mounted 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 lightsThe front lights are mounted on top of the bulldozer lift cylinders allowing them to project light over the trash rack and keep the lights above the concentrated debris environment for longer service life.
Heavy-duty steps and handlesThe heavy-duty steps and handles are manufactured from plate steel and solid rod to withstand the rigors of landfill operation.
High-capacity alternatorThe high-capacity alternator provides additional power required for electrical accessories such as supplemental lights and communications and entertainment radios.Raised prescreener helps reduce the likelihood of airborne paper or plastics plugging the air intake. It provides a larger air inlet.
Required AttachmentsThese options must be ordered in addition to the basic waste disposal arrangement.
Engine enclosuresThe engine enclosures consist of perforated hood and side panels. The enclosures help prevent airborne materials from entering the engine compartment and help reduce radiator plugging which can cause cooling system problems.
Hydraulic and fuel tank guardThe hydraulic and fuel guard helps protect implement hydraulic oil tank, battery box and fuel tank. • Plates are included to cover the light openings after they are repositioned on top of cylinders and ROPS.
Supplemental cylinder mounted lightsThe supplemental cylinder mounted lights (two front) are repositioned from the fenders opening to the top of the cylinders. The fender openings are covered with plates to prevent debris from entering.
Recommended OptionsSeveral additional options are recommended to assist in matching your site requirements.
Caterpillar landfill bladesThe Caterpillar landfill blades increase the dozing capacity in trash and helps prevent material from pilling over the blade and entering the radiator. Wear plates are available, and are recommended when working in highly abrasive materials.
Trapezoidal track shoesThe trapezoidal 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.
Front striker barsFront striker bars are angled design to prevent debris from riding up the track and damaging the fenders or fuel and hydraulic tanks. • The striker bar mounts are included in the basic waste handling arrangement. This allows the striker bars to be easily mounted if they are not initially ordered.
Rear striker barsThe rear striker bars incorporate a rigid drawbar and housing with large access doors for storage on machine not equipped with rippers. For machines with rippers, striker bars mount on ripper frame.
SY-KLONE® turbine air precleanerThe SY-KLONE® turbine air precleaner removes large particulates from the incoming air before they reach the air filter and extendes filter life two to four times. The turbine inside creates a bortex with the incoming air to eject particulates. This unit converts the standard, single-stage air cleaner to a two-stage system. This option includes a screen and a dash-mounted air cleaner indicator.
Laminated thermal shieldsThe laminated thermal shields cover the exhaust stack inside the compartment, hot-side of the turbocharger, and the exhaust manifold. These shields reduce surface temperatures well below the flash point of most common combustibles encountered.
Radiator (AMOCS)The radiator (AMOCS) 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.
Flexxaire™ fan engine control systemThe 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 thermostatically controlled fan provides optimum engine operating temperature.
ROPS-mounted air conditioner condenser and fansThe ROPS-mounted air conditioner and fans are relocated from the engine compartment to the ROPS. • Moving the condenser and fans away from the radiator reduces the concentration of debris and plugging. This relocation also increases the calculated cooling capacity of the machine for operation in higher temperatures.
Adjustable armrestsAdjustable armrest help improve operator comfort for shift-long productivity. No tools required.
Black painted hood, cylinders, and back of bladeThe black painted hood, cylinders, and back of blade reduces glare from lights while operating at night and also while operating in direct sunlight.
Hydraulic rippersHydraulic rippers are available as single or multi-shank to penetrate tough material fast and rip thoroughly.
