DYNAPAC CC424HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC424HF is a static smooth drum roller designed for efficient compaction in road construction and related applications. It features a 68-inch (1730 mm) wide drum with a diameter of 51.2 inches, delivering static linear loads of approximately 29.5 kg/cm per drum. The roller is equipped with dual vibration frequencies of 51 Hz (3060 vpm) and 67 Hz (4020 vpm), both with a nominal amplitude of 0.1 inches, generating a centrifugal force up to 31,923 lbs to optimize compaction performance. Powered by a Cummins engine producing 110 hp at 2200 rpm, the CC424HF supports a maximum operating weight of about 23,148 lbs and fuel capacity of 63.5 gallons. Its operating width spans 74 inches, with an inside turning radius of 219 inches, offering maneuverability in confined work sites. The machine’s dimensions include an overall length of approximately 16.4 feet, width of 6.17 feet, and height to the top of the cab near 9.8 feet. Features include an enclosed operator cabin, automatic vibration and water control systems (AVC and AWC), and a back-up alarm to enhance operational safety and efficiency. Its hydraulic and sprinkler systems ensure consistent drum wetting, while a shock-mounted operator platform enhances operator comfort. The CC424HF supports grades up to 45% with vertical oscillation of ±7°, enabling versatile terrain adaptability. This roller is designed for high productivity, ease of handling, and durability in demanding compaction tasks.
