AP555E Asphalt Paver

The AP555E provides all of the technology and capabilities of a large asphalt paver in a smaller, more mobile size. It excels in a wide range of applications from routine commercial jobs to highway operations.

Cat C4.4 Engine with ACERT Technology



ACERT Technology manages combustion using a combination of air management, precise fuel delivery and careful timing in order to lower emissions and meet U.S. EPA Tier 3 engine emissions requirements.

High Capacity Cooling System



The deckmounted cooling system provides a cool environment by exhausting hot air toward the hopper, away from operators and ground personnel.

High Ambient Temperature Cooling System



The standard, highcapacity cooling system provides efficient operation in high ambient temperatures. The system design provides quiet operation that benefits the operator and the surrounding environment.

Efficient Airflow Design



The airflow design draws ambient air across the engine compartment and through the coolers. This design allows the exhaust air to exit toward the hopper in order to provide a cooler engine compartment and cooler operating environment.

Variable Speed Fan



The variable speed fan is electronically controlled and hydraulically driven to provide ondemand cooling. This ondemand operation reduces engine power demand, lowers sound levels, and increases fuel efficiency.

Operator Comforts for a Productive Environment



The dual operating stations offer the bestinclass comfort, visibility and ease of use.

Dual Operating Stations



The dual operating stations incorporate fully equipped consoles, ground speed indicators, adjustable suspension seats with cup holders, armrests, and 76 mm 3 retractable seat belts.

Operator Visibility



The dual operators stations can be positioned in one of four different locations to provide optimum visibility. The stations can extend beyond the machine frame for good visibility when paving applications require precise control.

Tilting Consoles



The tilting consoles increase operator comfort by offering multiple positions. A 12volt power supply located on the right console allows for the use of accessories.

Advisor Monitoring System Simplifies Operation



The left operating console includes the Advisor Display that provides many unique features to assist the operator.

Advisor Monitoring System 40AMS41



The Advisor display provides access to a startup checklist, operator preferences, engine and machine operating parameters, Paving Calculator, and Paving by the Numbers.

Mobiltrac Undercarriage Performs in All Applications



The Mobiltrac undercarriage provides superior durability while delivering unmatched mobility, ride, and traction in a variety of conditions.

Mobiltrac Undercarriage



The Mobiltrac undercarriage combines the flotation and traction benefits of a crawler suspension with the mobility and ride quality of a wheeltype paver. The Mobiltrac system includes a durable, high strength rubber track belt with a thick outer cover and internal layers of flexible steel cable.

Large Ground Contact Area



The Mobiltrac ground contact area is 2460 mm 97 long and 406 mm 16 wide. This large footprint provides uniform weight distribution over the entire length of the belt.

Choice of Belt Designs



The Mobiltrac system offers a treadbar style belt or a smooth belt. Both belt styles are 62 mm 2.4 thick and provide good performance and wear characteristics, however, the smooth belt with beveled edges provides less disturbance on soft base materials.

Two Speed Planetary Drive



A fixed displacement motor drives a twospeed planetary providing quick mobility around the job site.

Independent Material Handling System Promotes HandsFree Operation



The gateless material handling system promotes handsfree operation by providing features such as ratio control dials, and independent control of each auger and each conveyor.

Precise Mix Delivery



The material delivery system provides precise mix delivery with minimal operator monitoring. The left and right conveyors in addition to the left and right augers are controlled independently. The ability to control these four components separately eliminates the need for feeder gates.

Ratio Control



The ratio of conveyor speed to the maximum auger speed is automatically maintained through the controller when changing paving speed. This ratio control feature is helpful when paving wider or thicker on one side of the screed.

OutboardMounted Conveyor Drives



The conveyors have outboardmounted motors, reducers and drive chains that maximize the tunnel area and reduce segregation.

Gateless System



The gateless conveyors run full of mix regardless of the auger speed. When changes in conveyor speed are required, delivery of mix to the augers is immediate. By not always having to run the conveyors at full speed, component wear is significantly reduced. Running at slower speeds can also help reduce the opportunity for segregation, especially when working with larger stone mixes that have a tendency to segregate.

Independent Auger Drive



The auger drive assembly is independent of the tractor, which allows the distance between the two conveyors to be significantly reduced. Keeping the conveyors close together allows the material to flow together more easily as it discharges into the auger cavity. The tunnel and auger design eliminates voids under the chain case in order to minimize segregation.

Adjustable Auger Range



The auger assembly is hydraulically adjustable with a range up to 215 mm 8.5. The ability to adjust the auger assembly simplifies loading and unloading from a transport vehicle. Also, when working with larger stone mixes, the augers can be adjusted to allow the mix to flow unrestricted under the auger assembly.

Generator System Provides Quiet Power



The high capacity generator provides power for the electric screed heat, auxiliary lights and job site tools.

Industrial, SinglePhase A.C. Generator



The tractormounted generator provides The beltdriven generator provides 25 kW at 60 to 100 Hz for the electric screed heat and the auxiliary power panel. Circuit breaker protection, internal electronic voltage regulation and a dual bearing design provide reliability.

Belt Driven



The beltdriven generator provides 25 kW at 60 to 100 Hz.

Optional Auxiliary Power Panel



The power panel provides 7 kW of power for auxiliary lighting and job site work tools. The panel includes six 120 V and one 240 V receptacle.

Serviceability Features That Youve Come to Expect



Simplified service means more time spent paving and less time spent on maintenance.

Advisor Monitoring System 40AMS41



The Advisor display lists diagnostic fault codes for machine functions making troubleshooting quick and easy.

Optional Product Link System



This optional system provides automatic machine location and hour updates that can be used to schedule service intervals, ensuring that maximum uptime and minimal repair costs are achieved.

Manual Overrides



The hydraulic pump solenoids incorporate manual overrides to assist troubleshooting procedures.

Large Access Doors and Panels



Preventative maintenance points can be accessed through the large swing open access doors and panels.

Remote Lubrication Points



Lubrication points are grouped in order to make routine service quick and easy.

ColorCoded and Numbered Electrical Wiring



Troubleshooting is efficient and simplified with the colorcoded and numbered wiring.

Screeds That Deliver Quality



Cat asphalt screeds with frontmount or rearmount extenders provide even material flow and unparalleled stability that result in smooth, high quality mats.

AS2252C VersAMat Screed



The AS2252C vibratory screed features narrow frontmounted extenders. The extenders utilize 229 mm 9 wide screed plates making it a perfect fit for commercial applications by reducing the need for handwork when changing paving widths. The main screed plate is 457 mm 18 wide measured front to back.

AS3251C ExtendAMat Screed



The AS3251C vibratory screed features hydraulicallydriven, rearmounted extenders. Heavyduty support tubes stabilize the extenders providing even material flow for high quality results on highways and streets as well as commercial applications. The main and extender screed plates are 457 mm 18 wide measured front to back.
