[. . . ] 1 tonne) 2550-5000 mm 8000 mm High Performance and Operator Comfort Make the AP655D the Perfect Choice The AP655D sets the standard in performance, operator comfort, ease of use, mobility and reliability. 6 Engine with ACERTTM Technology ACERTTM Technology works at the point of combustion to optimize engine performance. aCERTTM Technology incorporates an electronic controller to precisely deliver multiple injections of fuel. These multiple injections are combined with a refined air management system in order to generate fewer emissions and optimize fuel combustion while meeting European EU Stage IIIA engine emission regulations. [. . . ] The AMS display also allows the operator to: Calibrate the machine components Set the automatic engine speed control Monitor engine rpm's and operating temperatures Determine the required paving speed and tonnage requirements for a particular job Determine performance parameters such as distance traveled, operating hours, paving distance, paving hours, and engine fuel consumption Set the optional friction steering tension to the operator's preference Advisor Display 5 Mobil-trac Undercarriage Performs in All Applications The Mobil-tracTM undercarriage provides superior durability while delivering unmatched mobility, ride, and traction in a variety of conditions. 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 long and 406 mm wide. This large footprint provides uniform weight distribution over the entire length of the belt. Both belt styles are 58 mm 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. Friction Drive Wheel Smooth Belt Oscillating Bogies Automatic Belt Tensioning System Tread-Bar Belt Two Speed Planetary Steel Track Undercarriage The steel track undercarriage is available as an economic alternative to the Mobil-trac. 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. single Speed Planetary Quad Rear Bogie Single Speed Planetary Drive. A variable displacement motor drives a single-speed planetary that provides variable speed selection. The steel tracks ground contact area is 3048 mm long and 356 mm wide. This large footprint provides uniform weight distribution over the length of the track. Automatic Track Tensioning System D3 Track Rails 6 Independent Material Handling System Promotes Hands-Free Operation The material handling system promotes hands-free operation by providing features such as independent control of each auger and each conveyor. 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 conveyors have outboard-mounted motors, reducers and drive chains that maximizes the tunnel area and reduces segregation. 1 3 2 4 Independent Auger Drive. The auger drive assembly is independent of the tractor which allows the distance between the two conveyors to be significantly reduced. [. . . ] Single speed motors drive two speed planetary gear boxes to provide two propel ranges. The drive system is equipped with two switches located at the operator's station control console. The two switches are used as manual overrides and are directly linked to EDC's. The steel track drive system utilizes two dual path hydrostatic pumps and two variable displacement motors. [. . . ]
