DYNAPAC CC622HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC622HF is a double-drum vibratory roller designed for high-performance compaction of asphalt and base layers in road construction and large-area paving projects. This articulated roller features propulsion, braking, and vibration on both drums, providing excellent traction, maneuverability, and uniform compaction across the full drum width. The machine is equipped with a Cummins 4AA BT3.9-C diesel engine delivering 124.8 hp (92 kW), ensuring reliable power for demanding applications. With an operating weight of 27,778.3 lb (approximately 12.6 tonnes) and a static linear load of 439.6 lb/in, the CC622HF is suited for medium to heavy-duty compaction tasks. The 83.9-inch wide drum and 55.2-inch diameter drums provide a large compaction area and consistent mat finish. Vibration is adjustable between two frequencies—51 Hz and 63 Hz—with a high/low amplitude setting of 0.1 in, producing a maximum centrifugal force of 31,023.7 lb and a minimum of 17,310.3 lb to match varying material types and layer thicknesses. Maximum travel speed reaches 6.9 mph (10 km/h), supporting efficient operation on large sites. The compact overall length of 16.7 ft and a cab height of 10 ft contribute to good visibility and site mobility. Ideal for asphalt finishing and base compaction, the Dynapac CC622HF combines robust performance, precise control, and operator comfort in a modern, articulated smooth drum roller configuration.
