The Volvo PF6160 and PF6170 wheeled highway-class pavers have been designed for the next level of paving, with independent auger and conveyor systems, automatic conveyor tensioning and a patented front-wheel suspension. A number of features on these pavers provide contractors with more options in material flow. The auger system is now independent of the conveyor system. Each of the two auger and conveyor drives uses sonic sensors for more precise handling of material. The conveyor system has chains that are automatically tensioned for proper performance and less downtime. The conveyor chain cover cleans itself, providing easier maintenance. Reversible augers and conveyors are optional equipment.
