Road Paver Tracked - WheeledAFT 350 E/G - AFW 350 E/GThe machines of this class are ideal for small and medium sized job sites wheregood manoeuvrability for operating in restricted environments is requisite.Despite their compact dimensions these machines are able to pave in a width ofup to 4.5 m. The tracked version is suitable for job sites on difficult ground andensures a very thorough levelling effect.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.Large full rubber tyres are fitted to the front oscillating axles. The steeringsystem with the hydraulic pump provides smooth control when turning.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 controlledby means of an electro-hydraulic system. The front pushing rollers move insequence with the hoppers. The two adjustable seats, left and right, canslide externally. The dashboard is adjustable in accordance with the seatposition to ensure ease of operation. There are ground controls with antivandalguards for the road operator. A hydraulic foldable canopy with rearsupports ensures good visibility.4
