Tandem rollers compact right to the edge

The segmented drum and continuously selectable crab steering offset on Ammann’s new AV 70 X4 and AV 75 X4 tandem rollers allow excellent compaction right up to the edge. A direct drive system with two independent hydraulic pumps guarantees exceptional driving properties, while the rear-mounted Cummins BTAA3.3-C80 engine insulates operators from heat and vibration and allows for safe and convenient maintenance. A number of performance-enhancing and safety options are available on the new X4 models, including an open ROPS cabin with handrails and anti-vandal protection, and an asphalt temperature measuring instrument.
