Waste Handling Guards

Extensive guarding helps protect critical machine components, body panels and the radiator from being damaged by debris under harsh waste handling environments. Minimizing build-up helps prevent component damage.

Hinged Radiator Guard

The 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 and special hinge latches retain the guard in the open or closed positions.

Tilt Cylinder Lines Guards

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

Extreme Service Crankcase (belly) Guards

The 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 Guards

The chassis guards help protect the engine compartment by deflecting debris from rising upward along the chassis.

Idler Seal Guards

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

Final Drive Seal Guards

The 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.

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.

Debris Resistant Features

Additional modifications enhance productivity and help prevent damage.

Rear, Tank-mounted Lights

The 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 Lights

The 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 Handles

The heavy-duty handles are manufactured from solid rod to withstand the rigors of landfill operation.

High-capacity Alternator

The high-capacity 95-amp alternator provides additional power required for electrical accessories such as supplemental lights and communications and entertainment radios. The ducting helps prevent debris from entering into the alternator.

Additional Sealing

To help eliminate debris entry into areas of the machine additional sealing is provided. Key areas include: engine enclosures, platforms, hydraulic tank, ROPS support, battery box, striker bar box, and rear case opening.

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.

Required Attachments

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

Clamshell Guards

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

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.

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).

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.

Required Attachments

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

Enhanced Cab

The enhanced cab provides higher cab pressurization for improved cab air quality in dust and debris-laden applications. Includes a powered precleaner, with a high efficiency filter, which reduces system maintenance intervals.

Engine Enclosures

The 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. 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, battery box and fuel tank. • Plates are included to cover the light openings after they are repositioned on top of cylinders and ROPS.

Rear Striker Bars

The 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 counterweight-ready in case additional rear weight is needed. For machines with rippers, striker bars mount on ripper frame.

ROPS-mounted Air Conditioner Condenser and Fans

The ROPS-mounted air conditioner condenser and fans are mounted to the back of the ROPS to maintain overall machine height. • Moving the condenser and fans away from the radiator reduces the concentration of debris and plugging. This relocation also increases the cooling capacity of the machine for operation in higher temperatures.

Laminated Thermal Shields

The 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.

Supplemental Cylinder Mounted Lights

The supplemental cylinder mounted lights (four front) are repositioned from the fender/ openings to the top of the cylinders. The fender openings are covered with plates to prevent debris from entering.

Caterpillar Turbine Air Precleaner

The Caterpillar turbine provides improved engine air filtration by using the OPTIMAX dual-stage precleaner powered by the engine's intake and exhaust airflows. Intake air is spun by a flow driven impeller. Debris stratifies along the outer wall and is ejected back into the environment. Remaining contaminates are collected and removed by a secondary scavenger system, allowing only precleaned air to continue to the engine's air filter.

Recommended Options

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

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 multi-shank to penetrate tough material fast and rip thoroughly.

Beacon Light

A heavy-duty Federal Signal Pulsator 551 single flash (5 joules) strobe beacon unit is weather sealed and water resistant with the power supply encased in gel. The beacon is wired directly and can only be turned off by the disconnect switch. Extends above the highest part of the machine for enhanced visibility.

Remote Disconnect

Located in the cab, the remote disconnect switch is in series with the standard machine disconnect. The switch, located on the left side of the operator seat at knee level, allows the operator to access the disconnect switch quickly.

Computer Aided Earthmoving System (CAES)

The Computer Aided Earthmoving System (CAES) is a high technology earthmoving tool that allows machine operators to achieve maximum landfill compaction, desired grade/slope, and conserve and ensure even distribution of valuable cover soil with increased accuracy. This state-of-the-art machine control system delivers real-time elevation, compaction and grade control information to machine operators on an in-cab display. By monitoring grade and compaction progress, operators have the information they need to maximize the efficiency of the machine, resulting in proper drainage and optimum airspace utilization.
