Road Paver Tracked - WheeledAFT 500 E/G - AFW 500 E/GThe machines of this class are ideal for medium-to-large size job sites wheregood manoeuvrability, together with high performance, are requisite. Due to theirexcellent weight distribution, both the wheeled traction models (4x6 and 6x6) andthe tracked version are very easy to handle and are able to pave in a width of up to6.5 m for a wide range of applications.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 areadjustable and oscillating.The two adjustable seats, left and right, can slide externally. The dashboardis adjustable in accordance with the seat position to ensure ease ofoperation. There are ground controls with anti-vandal guards for the roadoperator. A hydraulic foldable canopy with rear supports ensures good visibility.12
