Ammann updates ARX light tandem rollers

Ammann's new ARX 20-2 light tandem roller Ammann’s new ARX 20-2 light tandem roller is one of four updated models.

Ammann has updated its ARX series of light tandem rollers for the European market.

The successor range to the company’s previous generation of Ammann ARX Light Tandem Rollers, the new double drum product line comprises the ARX 12-2, ARX 16-2, ARX 20-2 and the ARX 16-2C models.

The latter of which is equipped with a steel drum at the front and pneumatic tyres at the rear for greater traction and improved surface sealing.

Stage V compliant, the new models are fitted with Kubota engines and include a new vibratory setting for faster compaction.

Vlastimil Medek, global product strategy at Ammann, said, “The new setting enables vibratory frequencies to increase (3% at low frequency, 6% at high frequency). Improved impact spacing also optimises compaction quality.”

Unlike Ammann’s previous generations, the updated models allow operators to switch between drive modes without the assistance of a service technician.

Offering both in-line and off-set configurations, the models include Soft Drive and Hard Drive modes for steady directional changes and a Panic Stop feature.

Ammann said, “Panic stop idles the machine if the operator makes very sudden directional changes or significantly adjusts the travel lever position.”

Dashboard controls on the Ammann ARX 20-2 tandem roller Designed to appeal to both operators and rental companies, the Ammann’s new rollers offer simple operation.

While the new generation rollers have repositioned switches and a new armrest with integrated functions, the dashboard has remained largely unchanged for reasons of familiarity.

Medek said, “ARX dashboards and controls are consistent with other Ammann models, making it easy for crew members to switch between machines. This is particularly important for the rental market and when dealing with inexperienced operators.”

Something that will also appeal to rental companies in particular is the repositioned draining points.

These have been moved to external locations to prevent spills and lower maintenance times by around 75%.

Ammann said its new rollers are also easier and safer to transport, thanks to expanded lashing points, a higher central lifting point and the inclusion of a “transport” mode, which automatically disables vibration.
