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.
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.
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 incorporate fully equipped consoles, ground speed indicators, adjustable suspension seats with cup holders, armrests, and 76 mm (3") retractable seat belts.
The dual operating stations with sliding control console offer the best-in-class comfort, visibility and ease of use.
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.
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 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 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.
The Mobil-trac's ground contact area is 3020 mm (119") long and 406 mm (16") wide. This large footprint provides uniform weight distribution over the entire length of the belt.
The Mobil-trac system offers a tread-bar style belt or a smooth belt. Both belt styles are 58 mm (2.3") thick and provide good performance and wear characteristics, however, the smooth belt with beveled edges provides less disturbance on soft base materials.
A fixed displacement motor drives a two-speed planetary providing quick mobility around the job site.
A special quad bogie is positioned near the rear of the steel track in order to evenly distribute the load.
The steel track system incorporates D3 dozer track rails. The sealed and lubricated links include a split master link for dependable performance.
The track pads contain a special rubber compound in order to provide long life and good traction.
A variable displacement motor drives a single-speed planetary that provides variable speed selection.
The steel track's ground contact area is 3048 mm (120") long and 356 mm (14") wide. This large footprint provides uniform weight distribution over the length of the track.
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.
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.
The conveyors have outboard-mounted motors, reducers and drive chains that maximize the tunnel area and reduce segregation.
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.
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.
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 tractor-mounted generator provides 25 kW of power at 60 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.
The belt-driven generator provides full power with a variable frequency when the engine speed increases above 1275 rpm. The hydraulic-driven generator provides full power with a fixed frequency of 60 Hz when the engine speed increases above 1275 rpm.
The power panel provides 8 kW of power for auxiliary lighting and job site work tools. The panel includes four 120 V and two 240 V receptacles.
The Advisor display lists diagnostic fault codes for machine functions making troubleshooting quick and easy.
This 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.
The hydraulic pump solenoids incorporate manual overrides to assist troubleshooting procedures.
Preventative maintenance points can be accessed through the large swing open access doors and panels.
Lubrication points are grouped in order to make routine service quick and easy.
Troubleshooting is efficient and simplified with the color-coded and numbered wiring.
Project consulting provides a service for improving smoothness, density, and productivity.
Technical training offers in-depth hands-on training to mechanics at Caterpillar training centers or customer locations.
Paving Operations Training (POT) is a hands-on methodical approach to the process of paving. The process of “Paving by the Numbers” guides the crew when setting up to pull off the joint.
Parts for asphalt pavers and screeds are available at the Cat Dealer parts counter. Cat Dealers also utilize a world-wide computer network to find in-stock parts to minimize machine downtime.
