The Ammann Group is pleased to announce the release of the ARX 90 and ARX 110 Articulated Heavy Tandem Rollers featuring Oscillation. The rollers meet Tier 3 and Tier 4 Final emissions standards. They also utilise a design that maximises efficiencies and provides comfort.

Applications:

Medium and large jobsites

Transport construction (municipal and town roads, motorways, airfields)

Building construction (houses and industrial zones)

Oscillation is the key

The essential new product feature is Oscillation, a technology that helps rollers achieve compaction with less vibration.

Oscillation eliminates about 90 per cent of the stress on materials when compared with a traditional circular vibratory system. This is important when compacting on bridges, over sewers and utility lines and near buildings where a traditional vibratory approach can cause damage.

Oscillation uses less force but delivers both vertical and horizontal energy, essentially manipulating the aggregates into place. The drums maintain constant contact with the ground and deliver both static and dynamic forces.

In asphalt applications, the ARX 90 and ARX 110 able to work on hot mats sooner than traditional rollers, and they are able to stay on cold mats longer, too. This greatly expands the compaction window, essential for time-pressed crews.

The rollers also are great fits for sealing asphalt joints. The manipulating (kneading) motion of oscillation provides enough energy to break down the hot asphalt – yet does not damage the adjacent cold mat. Oscillation also eliminates vibration marks.

When working in soil applications, the compactors prevent damage to sensitive structures and over-compaction.

For those occasions when oscillation is not required, the ARX 90 and ARX 110 with oscillation feature heavy-duty, two-stage vibrator. Each drum has an independent vibratory pump. Amplitude and frequency are easily adjusted from inside the cab. The non-split drums offset up to 17 cm on both sides.
