New rollers offer high levels of productivity and low emissions in soil and asphalt applications
AMMANN’s new ART 240 StV pneumatic-tyred rollers are said to meet the world’s strictest emissions standards while excelling in soil and asphalt applications.
The rollers offer high productivity and are well suited to applications such as motorways, railways, airfields, industrial zones, and residential areas. They are powered by EU Stage V / US EPA Tier 4f engines from Deutz with EGR, DOC, SCR and DPF technology for the lowest emissions.
The compactors are versatile, with a ballasting system that offers weights ranging from 9 tonnes up to 24 tonnes – unique to the market. Additional ballasting blocks are easy to add to the bottom of the machine frame via forklift. Machine weight can also be increased by adding ballasting materials such as sand, metal scraps, concrete, or water inside the machine frame. The total available ballasting space is 3.7 cubic metres.
Front pairs of wheels are connected using an isostatic system that allows movement of +/- 50mm. The comprehensive front-axle solution combines +/- 3 wheel oscillation and constant tyre contact, even in difficult terrain, whilst the air-on-the-run system allows tyre pressure control from the cab.
Intuitive controls simplify handling and operation. The cab, with its two working stations, is spacious and offers optimal visibility – with operator sight lines to the entire jobsite as well as the working areas to the front and rear of the machine.
A maintenance-friendly design with ground-level access to the main drain ports and no tools needed for daily inspections, helps to minimize downtime.
