Cat® C6.6 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 European Stage IIIa engine emissions requirements.
Fumes Management System
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.
High Capacity Cooling System
The deck-mounted cooling system provides a cool environment by exhausting hot air toward the hopper, away from operators and ground personnel.
High Ambient Temperature Cooling SystemThe 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 DesignThe 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 FanThe 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.
Operator Comforts for a Productive Environment
The dual operating stations with sliding control console offer the best-in-class comfort, visibility and ease of use.
Dual Operating Seats with Sliding ConsoleThe dual operating seats are adjustable suspension seats with cup holders, armrests, and 76 mm (3") retractable seat belts. The operator's console slides from seat to seat for optimal operator visibility.
Operator VisibilityEach of the dual operating seats can be positioned in one of five different locations to provide optimum visibility. The seats can extend beyond the machine frame for improved visibility when paving applications require precise control.
Sliding Control ConsoleThe sliding control console increases operator comfort by allowing the operator to control the machine from the side that provides the best visibility. A 12-volt power supply located on the console allows for the use of accessories.
Advisor Display Simplifies Operation
The sliding control console includes the Advisor Display that provides many unique features to assist the operator.
Advisor DisplayThe Advisor display provides access to a start-up checklist, operator preferences, engine and machine operating parameters, “Paving Calculator”, and “Paving by the Numbers.”
Wheel Undercarriage System
The wheel undercarriage system provides excellent mobility and maneuverability along with a smooth ride for optimum performance.
Excellent MobilityThe sharp turning radius and high propel speeds allow the paver to move quickly around the job site.
Three Propel ModesPave, travel and maneuver modes provide good control and versatility. The new maneuver mode provides a 1.4 m (4' 8") turning radius for excellent maneuverability in tight quarters.
Speed ControlA speed control dial located on the operating console allows the operator to set a maximum propel speed. When the propel lever is moved to the full forward position, the paver returns to the preset speed.
Steering AssistA position sensor located in the left steering cylinder provides good maneuverability by adjusting the drive speed of the propel motors according to the steering angle of the front wheels. This feature allows the machine to turn while maintaining a consistent travel speed, leading to better mat quality and less wear on the drive system.
Large Drive TiresThe 16.00 x 25 sand-rib drive or radial tires provide good tractive effort and a smooth ride.
Large Steering TiresThe 13" x 22", solid rubber steering tires provide maximum ground contact, leading to good turning capability.
Front SuspensionFour, front solid rubber steering wheels are mounted on pairs of oscillating bogies, providing a smooth ride.
Long Wheel BaseThe long wheel base provides good tractive effort and stability on soft base materials.
Front Wheel Assist (Optional)The front wheel assist feature provides power to the front bogie wheels for additional tractive effort.
All-Wheel Assist (Optional)The all-wheel assist feature provides power to the front and rear bogie wheels, maximizing tractive effort.
Independent Material Handling System Promotes Hands-Free Operation
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.
Precise Mix DeliveryThe 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 ControlThe 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 DrivesThe conveyors have outboard-mounted motors, reducers and drive chains that maximize the tunnel area and reduce segregation.
Gateless SystemThe 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 DriveThe 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 RangeThe 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, Single-Phase A.C. GeneratorThe 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.
Choices Available (Belt or Hydraulic Driven):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.
Optional Auxiliary Power PanelThe 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.
