AP555E PAVER

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.

BENEFITS AND FEATURES

The ventilation system draws fumes from the conveyor tunnel as well as the auger chamber and redirects them away from the operator for a more comfortable working environment.

BENEFITS AND FEATURES

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

BENEFITS AND FEATURES

High Ambient Temperature Cooling System The standard, high-capacity 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 on-demand cooling. This on-demand operation reduces engine power demand, lowers sound levels, and increases fuel efficiency.

The dual operating stations offer the best-in-class comfort, visibility and ease of use.

BENEFITS AND FEATURES

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 operator's 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 12-volt power supply located on the right console allows for the use of accessories.

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

BENEFITS AND FEATURES

Advisor Display The Advisor display provides access to a start-up checklist, operator preferences, engine and machine operating parameters, “Paving Calculator”, and “Paving by the Numbers.”

The Mobil-trac™ undercarriage provides superior durability while delivering unmatched mobility, ride, and traction in a variety of conditions.

BENEFITS AND FEATURES

Mobil-trac Undercarriage The Mobil-trac undercarriage combines the flotation and traction benefits of a crawler suspension with the mobility and ride quality of a wheel-type paver. The Mobil-trac 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 Mobil-trac 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 Mobil-trac system offers a tread-bar 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 two-speed planetary providing quick mobility around the job site.

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

BENEFITS AND FEATURES

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.

Outboard-Mounted Conveyor Drives The conveyors have outboard-mounted 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.

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

BENEFITS AND FEATURES

Industrial, Single-Phase A.C. Generator The tractor-mounted generator provides The belt-driven 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 belt-driven 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.

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

BENEFITS AND FEATURES

Advisor Display 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.

Color-Coded and Numbered Electrical Wiring Troubleshooting is efficient and simplified with the color-coded and numbered wiring.
