DYNAPAC CC522CHF STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC522CHF is a static smooth drum roller designed for efficient compaction in road construction and similar applications. It features a robust single steel drum with a diameter of 55.2 inches and a width of 77.2 inches, delivering a significant static linear load of 455.2 pounds per inch. The machine generates a high centrifugal force of 26,078 lbs and a low centrifugal force of 16,636 lbs, maintaining a nominal amplitude of 0.1 inches with vibration frequencies of 50 and 63 vpm for effective soil and asphalt compaction. Powered by a Cummins 4AA BT3.9-C engine, the roller produces a gross power output of 124.8 hp at 2200 rpm, enabling a maximum travel speed of 6.9 mph. The overall machine dimensions include a height of 10 feet to the top of the cab, width of 6.9 feet, and length of 16.7 feet, supporting stable operations on diverse terrains. The operating weight is approximately 25,794 lbs, which contributes to its compaction performance. The CC522CHF is engineered for durability and operational efficiency in smooth drum rolling, with an emphasis on static compaction rather than vibratory. Its design ensures uniform pressure distribution and consistent compaction results, suitable for medium to large-scale paving projects where static rolling is preferred to minimize ground disturbance. The machine's balance of power, weight, and drum specifications make it a reliable choice for professionals requiring precise and heavy compaction.
