Ammann’s improved rubber tyred rollers boost efficiency

6791 Ammann has upgraded its rubber tyred asphalt compactor offering. The revamped ART 240 meets the Tier 4 Final/Stage IV emissions requirements of North America and Europe. The large cab offers high working comfort with a seat that can be moved to suit requirements and has good all round visibility due to large glass panels. Novel features to maximise performance in different conditions include a front isostatic oscillating axle and a rear-drive system that provides the required power, regardless of tyre pressures or ballast weight. The machines are said to deliver high quality compaction and suit finishing applications.
