Ammann light tandem rollers have been enhanced for contractors who rent the machines – and the rental houses that supply them.
The rollers feature a new Kubota D1703-M-DI engine that does not require any Engine After-Treatment Technology (EAT) to meet the latest EU Stage V/U.S. Tier 4f emission standards. This appeals to contractors who rent the machines and aren’t willing, or comfortable, maintaining the Diesel Particulate Filters (DPF) or Exhaust Gas Recirculation (EGR) systems. Rental fleet owners also appreciate the reduced maintenance, marketability, and resale value of a non-DPF product.
The engine is robust, with 19 kW of power – a significant amount given the varying lightweights of the machines.
The updated rollers are the ARX 23.1-2 Stage V, the ARX 23.1-2C Stage V, the ARX 26.1-2 Stage V and the ARX 26.1-2C Stage V. They remain popular machines in part because of an articulation joint that enables quick drum adjustment from in-line to off-set configurations and fully electronic drive levers for smooth starts and stops.
Rollers that are off-set are able to work close to obstructions. Operators need to watch only one drum, knowing the second will be a safe distance from the obstruction. The in-line setting, which enables equal distribution of compaction forces, is preferred on more open job sites.
The articulation joint, which makes the in-line/off-set adjustment possible, is maintenance-free.
Contractors also appreciate the machines’ ease of operation. The rollers utilize an intuitive dashboard layout and offer exceptional front and rear visibility. An Led light system and reduced sound levels improve operator and job site safety.
Working widths range from 1000 mm to 1200 mm. Weights range from 2 tonnes to 2,5 tonnes.
Applications include small and medium construction sites, city roads, boardwalks, city street repairs, and road maintenance.
The “C” versions are combination machines that utilise a steel drum in front and four pneumatic tires in the rear.
Key features of the rollers include:
- Electronic drive lever for smooth starts and stops, especially important on asphalt jobs
- Spacious operator platform with sliding seat for comfort and visibility
- Simple and reliable dashboard with intuitive machine control, helping inexperienced operators succeed
- Accessible service and maintenance points for cost savings
- Maintenance-free parts for the low cost of ownership
- Optional ACE, the Intelligent Compaction tool for optimal efficiency
