DYNAPAC CC122C STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC122C is a static smooth drum roller engineered for compacting thin layers and soft asphalt compounds. It features a front drum diameter of 2.3 feet and a drum width of 47.3 inches, delivering a centrifugal force of 6,069.9 lbs at medium amplitude, with vibration frequencies ranging from 58 to 67 vibrations per minute and a nominal amplitude of 0.1 inches. The static linear load is approximately 185 pounds per inch, enabling efficient compaction performance. Powered by a Deutz D2011 L02 I engine, the roller produces a gross power output of 29.6 hp (22 kW) at 2800 rpm. The engine’s inline 2-cylinder design is oil-cooled, offering reliable operation and low running costs across diverse environments. The machine has a fuel capacity of 13.3 gallons and a maximum speed of 4.4 mph (6 kph). It stands 8.7 feet tall to the top of the cab, with an overall width of 3.9 feet and an overall length of approximately 8 feet. The ground clearance measures 6.9 inches, and it features a tight inside turning radius of 0.7 feet, allowing for excellent maneuverability. The Dynapac CC122C’s operating weight is around 5,357 lbs, making it suitable for small to medium-sized paving and repair tasks such as sidewalks, bicycle trails, and minor streets. The roller’s robust compaction system combines effective force, controlled vibration, and speed to optimize asphalt compaction and ensure surface smoothness.
