About · Dynapac CC120Overview
The Dynapac CC120 is a single-drum vibratory soil compactor in the light-to-mid tandem roller segment, with an operating weight of 2,600 kg and an engine output of 35 hp. It is positioned as a compact, maneuverable machine suited to sites where a larger compactor would be impractical. Dynapac's engineering focus on consistent drum frequency and straightforward serviceability gives the CC120 a recognized standing among contractors who prioritize reliability in this weight class.
Typical applicationsWhere this machine is used
The CC120 is used primarily for compacting granular soils, sub-base layers, and asphalt patches on road maintenance, utility reinstatement, and small-to-medium paving projects. Its compact footprint makes it well suited to confined urban work zones, parking areas, and trench backfill operations. Contractors also deploy machines in this class for shoulder work and residential infrastructure where heavier equipment cannot maneuver effectively.
Used-market inspectionWhat to check before buying
Before purchasing a used CC120 or any compactor in this class, inspect the drum shell closely for cracks, flat spots, or uneven wear patterns that indicate historical overloading or impact damage. Check the vibration system by running the machine and confirming that amplitude and frequency engage without abnormal noise or excessive heat buildup at the bearing housings. Examine all hydraulic lines, fittings, and the steering articulation joint for leaks and play, as these are high-wear points on articulated compactors. Review the engine compartment for oil leaks and coolant condition, and confirm that the air filter housing and fuel system show evidence of routine maintenance. Request any available service records, and if none are present, factor the cost of a full fluid service and inspection into your acquisition planning.
Current marketPrice position
Within the light compactor segment, the CC120 is most frequently cross-shopped against the Bomag BW120 and the Ammann ARX26. Compared with the Bomag BW120, which competes directly on weight and power, the CC120 is often evaluated on parts availability and dealer support infrastructure. The Ammann ARX26 targets a similar operating weight but is positioned with a focus on compaction measurement technology, which appeals to contractors who require documented compaction data for quality-assurance purposes. Across all three models, the attributes that move a machine within its price band are accumulated operating hours, overall mechanical condition, drum surface condition, the presence of a functional ROPS or cab enclosure, and any additional compaction-monitoring attachments. Service history documentation and geographic proximity to dealer support networks also influence where a specific unit lands within the spread.
