Ammann’s ART 280 pneumatic roller offers versatility

Ammann says that its latest model pneumatic asphalt compactor is more versatile, due to its innovative ballasting system. This modular ballasting system allows the machine weight to be adjusted from 9-28tonnes in just one hour by using a forklift. This equates to a load/tyre adjustment from 1,125kg to 3,500kg. The system allows the use of varied ballasting materials including water, steel, concrete and sand. A system allows control of tyre pressure from the cab, making it easy for the operator to control machine weight and tyre pressure, the two main tyred roller compaction factors.

The Ammann ART 280 Hydrostatic Tyred Roller is available with different engines to meet local requirements on emissions levels. The roller is powered by the latest Tier 4 Final/Stage 4 engine from Deutz with EGR, DOC and SCR technology. In less regulated countries, the compactor features a Tier 3/Stage 3A Deutz engine with EGR and muffler.

Front isostatic axles with oscillation are said to offer higher stability and increased surface coverage and quality. The roomy cabin offers low sound levels, a 170° rotating seat, a multifunction display and good all-round visibility. The new roller is said to provide easy access for maintenance and servicing, lowering downtime.
