Mobil-trac Undercarriage Performs in All ApplicationsThe Mobil-trac undercarriage provides superior durability while delivering unmatchedmobility, ride, and traction in a variety of conditions.Automatic BeltTensioning SystemSmooth BeltTread-Bar BeltOscillating BogiesMobil-trac Undercarriage. The Mobil-trac undercarriagecombines the flotation and traction benefits of a crawlersuspension with the mobility and ride quality of a wheel-typepaver.The Mobil-trac system includes a durable, high strength rubbertrack belt with a thick outer cover and internal layers offlexible steel cable.Large Ground Contact Area. The Mobil-trac’s ground contactarea is 3020 mm long and 406 mm wide. This large footprintprovides uniform weight distribution over the entire length ofthe belt.Choice of Belt Designs. The Mobil-trac system offers atread-bar style belt or a smooth belt. Both belt styles are58 mm thick and provide good performance and wearcharacteristics, however, the smooth belt with beveled edgesprovides less disturbance on soft base materials.Two Speed Planetary Drive. A fixed displacement motor drivesa two-speed planetary providing quick mobility around thejob site.Two SpeedPlanetaryFriction DriveWheelSteel Track UndercarriageThe steel track undercarriage is available as an economic alternative to the Mobil-trac.OscillatingBogiesQuad Rear Bogie. A special quad bogie is positioned near therear of the steel track in order to evenly distribute the load.D3 Track Rails. The steel track system incorporates D3 dozertrack rails. The sealed and lubricated links include a splitmaster link for dependable performance.Long Life Bonded Track Pads. The track pads contain a specialrubber compound in order to provide long life and goodtraction.Single Speed Planetary Drive. A variable displacement motordrives a single-speed planetary that provides variable speedselection.Large Ground Contact Area. The steel tracks ground contactarea is 3048 mm long and 356 mm wide.

Independent Material Handling System Promotes Hands-Free OperationThe material handling system promotes hands-free operation by providing features such asindependent control of each auger and each conveyor.152436Precise Mix Delivery. The material delivery system providesprecise mix delivery with minimal operator monitoring. Theleft and right conveyors in addition to the left and right augersare controlled independently.Outboard-Mounted Conveyor Drives. The conveyors haveoutboard-mounted motors, reducers and drive chains thatmaximizes the tunnel area and reduces segregation.Independent Auger Drive. The auger drive assembly isindependent of the tractor which allows the distance betweenthe two conveyors to be significantly reduced. Keeping theconveyors close together allows the material to flow togethermore easily as it discharges into the auger cavity. The tunneland auger design eliminates voids under the chain case inorder to minimize segregation.Adjustable Auger Range. The auger assembly is hydraulicallyadjustable with a range of 215 mm. The ability to adjust theauger assembly simplifies loading and unloading from atransport vehicle. Also, when working with larger stone mixes,the augers can be adjusted to allow the mix to flowunrestricted under the auger assembly.Power Folding Front Apron (Optional). The front hopper apronfolds rearward providing good material flow. It reduces cleanout effort and time, a feature the crew will really appreciate.A switch located on the operating control console providespower to the hydraulic folding apron.*Note: The front hopper apron is standard without the powercontrol and folding wings. Manual operation is required.Adjustable Push Rollers. The four position adjustable pushrollers provide a contact point between the paver and the truckto center the load and assist steering while unloading.781 Curved Hopper Design2 Independently ControlledConveyors3 Narrow Chain Guard4 Folding Front Apron5 Independent Auger Drives6 406 mm Auger Diameter7 Foldable Wings8 Power Folding Front Apron7
