DYNAPAC CC424/524/624HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC424/524/624HF series are static smooth drum rollers designed for effective compaction in various road construction and maintenance applications. These models feature drum widths ranging from 68 to 84 inches and a drum diameter of 51.2 inches, enabling wide and efficient coverage. Powered by a Cummins QSB 4.5 T3 turbocharged diesel engine delivering 110 hp, these rollers have an operating weight of approximately 23,150 lb and a fuel capacity of 63.5 gallons, supporting prolonged operation. The machines achieve a maximum speed of 7.5 mph, suitable for precise compaction control. Vibration frequencies are available at 51 and 67 Hz with nominal amplitudes of 0.1 inches, producing centrifugal forces up to 31,923 lb to optimize soil or asphalt layer density. The overall dimensions include a length of 16.38 feet, width of 6.17 feet, height to the top of the cab at 9.81 feet, wheelbase of 12.11 feet, and ground clearance of 12.21 inches, ensuring good stability and maneuverability. Hydraulic and vibration systems employ axial piston pumps and motors for efficient drive and compaction functionality. Safety features include hydrostatic service braking forward and reverse, and a failsafe multidisc parking brake in both drums. Optional features such as off-set drums and emulsion sprinkler systems enhance operational versatility. This combination of power, weight, and vibration control renders the CC424/524/624HF series ideal for high-quality, uniform compaction of asphalt and granular materials.
