Dynapac CO4200 VI Double Drum Roller

The Dynapac CO4200VI is a large-class asphalt roller with a drum width of 66 inches. This machine features a double-drum configuration with vibration on the front drum and oscillation on the rear drum, providing excellent compaction efficiency while reducing stress on underlying structures. Powered by a high-performance Cummins turbo diesel engine and combined with its large drum diameter and hydrostatic drive with series-connected radial piston motors, the CO4200VI delivers excellent accessibility and strong hill-climbing performance.

It is ideal for large-scale compaction projects near sensitive areas such as bridges, pipelines, and buildings, ensuring high compaction efficiency while minimizing vibrations transmitted to surrounding structures.
