Ammann Unveils Line of Articulated Light Tandem Rollers

Compactors Can Work Near Curbs and Other Obstructions

LANGENTHAL, Switzerland – New light tandem rollers from Ammann feature drums that can quickly be adjusted from in-line to off-set configurations, helping operators reach compaction goals – even when working near obstructions.

The rollers are the ARX 36-2, the ARX 40-2, the ARX 40-2C, the ARX 45-2 and the ARX 45-2C.

“Rollers that are offset are able to work close to curbs and other obstructions,” said Josef Dementěv, Global Product Specialist for Machines at Ammann. “Operators need 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 jobsites. The adjustment between in-line and off-set configurations is done manually and is easy for operators to make. The articulating joint, which makes the in-line/off-set adjustment possible, is maintenance-free.

Kubota engines that meet Tier 4 Final emissions standards and are Stage V ready power the rollers. The machines also feature a number of design enhancements. Among them: an intuitive dashboard layout, a redesign of the front and rear of the machine and a new LED light system. A new protective guardrail has been placed around the dashboard as well.

The “C” versions are combination machines, which utilise steel drums in front and pneumatic tyres in the rear.

Reduced sound levels improve operator safety, as does the new LED light system. Working widths range from 1300 mm to 1380 mm. Weights range from 3.7 tonnes to 4.5 tonnes.

Applications include small and medium construction sites, city roads, boardwalks, city street repairs and road maintenance.

The new models are great fits for the rental market. “The intuitive operator control panel and spacious platform offer comfort to suit a variety of operators,” said Dementěv. “Durable components and fuel-efficient engines maximise uptime and lower lifetime operating costs.”

The rollers are compatible with Ammann ServiceLink, a fleet management system that enables close monitoring to keep owners informed of machine service needs.

Other key features include:

• An electronic drive lever for smooth starts and stops, especially important on asphalt jobs
• An optional Intelligent Compaction tool for optimal efficiency
• Perfect all-around machine visibility for safety on the jobsite
• Accessible service and maintenance points
• Maintenance-free parts

These machines are built to help operators succeed – and ultimately to help business owners find the productivity and profitability they need.
