Ammann single-drum rollers ASC 70 to ASC 250 – the Swiss compaction brand from Langenthal with plant in Nové Město: ASC for Ammann Soil Compactor, the number as weight class in tenths of a tonne, PD for padfoot
Ammann of Langenthal in the canton of Bern has been at home in road building since 1869 – asphalt mixing plants are the core business – and the single-drum rollers were added in 2005 with the takeover of the Czech maker Stavostroj of Nové Město nad Metují, which had developed the ASC range. The type logic: ASC stands for Ammann Soil Compactor, the number gives the weight class in tenths of a tonne – ASC 70 about 7 t, ASC 110 11 t, ASC 150 15 t, ASC 250 about 25 t, one of the heaviest single-drum rollers on the market – PD marks the padfoot drum for cohesive soils, HD the heavy-duty version with reinforced drive for gradients. The engines come from Cummins: B4.5 in the small, QSB4.5 in the medium and QSB6.7 in the big models, at 2,200 rpm.

The register lists 14 versions with 75.3 to 155.1 kW and operating weights from 7,085 to 25,515 kg.
Ammann belongs with Bomag, Hamm, Dynapac and Caterpillar to Europe's five big compaction brands; the ASC rollers carry the ACE compaction-measurement system with which the machine regulates its own amplitude, and are particularly common in Eastern Europe and the Middle East.
On used rollers, operating hours, the condition of vibration bearings and rubber buffers, leak-free travel and vibration hydraulics, play in the articulation joint, pads on PD models, drive axle on HD models and parts supply through Ammann and Cummins count.
