Compaction versatility from Ammann

Ammann’s latest compact twin drum rollers are highly versatile

Ammann claims that its latest ARX 16, ARX 26-2 and ARX 45-2 T4 Final compact tandem rollers are highly versatile. The machines benefit from drums that can quickly be adjusted from inline to offset configurations, for working near obstructions. The ARX 16 is left- and right-side support-free.

Compactors that are off-set are able to work close to kerbs and other obstructions. Operators need watch only one drum, knowing the second will be a safe distance from the obstruction. The inline setting, which enables equal distribution of compaction forces, is preferred on more open jobsites.

The adjustment between inline and offset configurations is done manually and is said to be easy for operators to make. The articulating joint, which makes the inline/offset adjustment possible, is also said to be maintenance-free.

The rollers are powered by Kubota engines that meet Tier 4 Final and Stage V emissions standards. The machines also feature a number of design upgrades, including a redesign of the front and rear for improved comfort and visibility. Weights range from 1.4-4.5tonnes.

Available on the machines is ACEforce, Ammann’s proprietary Intelligent Compaction system. ACEforce measures and evaluates material stiffness in absolute values and provides this information to the operator on a display. The system ensures compaction is achieved before moving onto the next area of the jobsite. ACEforce also prevents unnecessary passes and over-compaction.
