[. . . ] Undercarriage The AP655D can be equipped with either the Mobil-tracTM undercarriage or the steel track undercarriage. The Mobil-trac system combines the traction and flotation benefits of a crawler undercarriage with the mobility, speed, and ride characteristics of a wheel paver. A steel track undercarriage is available as a more economical alternative. 6 Maneuverability Cat track-type pavers provide maneuverability that is unmatched in the industry. [. . . ] 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. 4 Operator Comforts for a Productive Environment The dual operator's station with sliding control console promotes optimum comfort, visibility and ease of use. The ergonomic dual operator's station incorporates a sliding control console, ground speed indicators, adjustable suspension seats, armrests and retractable seat belts. The dual swing-out operator's station can be positioned in one of five different locations to provide optimum visibility. The stations can extend beyond the machine frame for good visibility when paving applications require precise control. The sliding control console is fully equipped with comprehensive controls allowing the operator to conveniently monitor all machine functions. The optional folding canopy provides full width with two side extending wings for optimum comfort and protection. Advisor Monitoring System Simplifies Operation The sliding control console includes the Advisor Display that provides many unique features to assist the operator. The auger assembly is hydraulically adjustable with a range of 215 mm. 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. It reduces clean out effort and time, a feature the crew will really appreciate. A switch located on the operating control console provides power to the hydraulic folding apron. *Note: The front hopper apron is standard without the power control and folding wings. The four position adjustable push rollers provide a contact point between the paver and the truck to center the load and assist steering while unloading. 5 6 7 8 1 Curved Hopper Design 2 Independently Controlled Conveyors 3 Narrow Chain Guard 4 Folding Front Apron 5 6 7 8 Independent Auger Drives 406 mm Auger Diameter Foldable Wings Power Folding Front Apron 7 Optional Generator System Provides Quiet Power The high capacity generator provides power for the electric screed heat, auxiliary lights and job site tools. The tractor-mounted generator provides 25 kW of power at 60 Hz for the electric screed heat and the auxiliary power panel. 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. [. . . ] 6 liters Suspension The high-speed Mobil-tracTM undercarriage consists of a durable, high-strength rubber belt with a thick outer cover that includes five internal layers of flexible steel cable. Drive traction is provided by a hydraulic tensioning cylinder with accumulator that maintains friction between the belt and the drive wheels. Rubber-coated steel mid-wheels provide smooth ride and high traction efficiency by distributing weight over the entire length of the belt. The steel track undercarriage consists of four 241 mm diameter track rollers, a special rear, four roller 152 mm diameter bogey, and two 152 mm diameter single roller return idlers per side. [. . . ]
