Road Paver Tracked - WheeledAFT 270 E/G - AFW 270 E/GThe machines of this class have been designed for use, primarily, on small andnarrow sites where their compact dimensions, their manoeuvrability and very goodtraction fulfil the typical requirements of a contractor for these kinds of jobs. Thetraction on wheels enables a good transfer speed on the road, reducing idling time.The wheeled machine has three axles: in the front, two axles for steeringand in the rear, the axle for traction. The rear axle is fitted with largepneumatic tyres so that the machine can also be driven on soft ground.The current version is equipped with four-wheel drive traction as standard.The steering system, with a hydraulic pump, provides smooth control whenturning.Traction on tracks is suitable for job sites located on difficult ground and itassures a very thorough levelling effect.The tracked machine has rubber pads and an automatic tensioningdevice system with a grease accumulator. The hydrostatic transmissionis implemented by two variable flow-rate pumps that feed two motorswith two displacements directly attached to the planetary gearboxes thatoperate the tracks. An electronic and proportional control mounted oneach pump provides a progressive start and stop and maintains the setspeed constant. The steering-wheel is electronically controlled; the speedremains constant when steering.The hoppers are independently controlled by means of an electro-hydraulicsystem. The front pushing rollers move in sequence with the hoppers.2
Technical specificationsFeeding of materialThe feeding system for the material is carried out by twoindependent reverse chain belt conveyors and augerscontrolled by paddle microswitches which regulate the flowof material to the screed in order to maintain the mosteffective distribution of material under any conditions. Theheight of the augers is electro-hydraulically adjustable.Man on board versionMan on board operations from one adjustable seat that canslide to the left or the right. The dashboard is adjustablein accordance with the seat position to facilitate ease ofoperation. There are ground controls with anti-vandalguards for the road operator. A foldable canopy with rearsupports ensures good visibility.Screed optionsThe FSV 270 E/G is a vibrating screed equipped with gas orelectric heating, automatic lighting and temperature controland the ISR system (Screed Assist) for pressure adjustment.Max paving widths:FSV 270 E/G1400–2730 mmOptional 3330 mmApplicationssquares and courtyardssmall building lotsfootpathscycle tracksclosing trenchesurban centresmunicipal roads and small parking areasEquipmentStandardAutomatic heating controlHydraulically adjustable augers heightFour wheel drive (DT) for AFW 270The ISR system (Screed Assist)Folding canopy (Man on board version)OptionalLongitudinal levelling systemSlope control systemReduction plates at 500 mmMechanical extensions at 3330 mmFolding canopy (F version) for AFT 270Proportional ultrasonic augers controlOn-Off ultrasonic augers controlElectro-hydraulic camber adjustmentTracked Paver AFT 270 E/G Wheeled Paver AFW 270 E/GWeight kg 5200 / 5000 (F) 5200Diesel engine Deutz D2011L03i / kW 33.2 (45 HP) at 2500 rpm Deutz D2011L03i / kW 33.2 (45 HP) at 2500 rpmPaving width mm 1400 – 2730 1400 – 2730Max paving width mm 3330 3330Production t/h 150 1503
