Dynapac fifth-generation CA2500 through CA4000 single-drum vibratory rollers can be equipped with multiple levels of compaction control from the basic Compaction Meter with new Active Bounce Control technology to the full Compaction Optimizer. Controls can be paired with its Intelligent Compaction solution, the Compaction Analyzer. Open-platform or cab options include a seat that moves 180 degrees in unison with steering column and instrument panel. Loss of traction can be counteracted with a toggling gear shifting system or with optional passive anti-spin traction system. Engine options vary by size but either Cummins four- or Deutz six- cylinder diesels, both Tier 4-Interim.
