BOMAG develops sophisticated, high production articulated asphalt compactors
BOMAG is now introducing its 5th generation of articulated tandem rollers, the BW 191 and BW 206. These machines compete in the 12tonne and 16tonne classes and are said to be designed for use on thicker asphalt layers as well as for static compaction of open-pore asphalt. Three exciter systems are available for both models. In addition to the applications where the proven Double Vibration and Asphalt Manager features are used, the Tango Oscillation function can be used compaction in difficult areas such as on hot to cold joints, on bridges or near buildings. This last feature is controlled by a single amplitude, allowing operators to use the system more easily. The firm says that the drum will not bounce in this mode as the system works at a tangent to the surface. The feature also prevents aggregate crushing. And with the large diameter drum no bow waves are pushed ahead, even at higher working speeds.
The new tandem rollers also feature the sophisticated Bomag Economizer system, which measures compaction and increases efficiency on site by showing progress and avoiding unnecessary passes. The machines also have large cabs with high visibility, giving the driver a clear view of the drum edge and a 360° view of the site. The engine and cab are also separated from each other and to keep maintenance simple, there are no lubricating points on these rollers. All other maintenance areas are readily and quickly accessible from the ground.
