DYNAPAC CC522HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC522HF is a static smooth drum roller designed for efficient compaction in road construction and asphalt applications. It features a robust Cummins 4AA BT3.9-C engine delivering a gross power of 124.8 hp (92 kW), enabling a maximum operating speed of 7.5 mph (11 kph). The roller has an operating weight of 26,125 lbs (11,850 kg) and dimensions including a height to the top of the cab of 10 ft and an overall length of 16.7 ft. Its drum measures 55.2 inches (140 cm) in diameter and 76.8 inches (195 cm) wide, offering a substantial contact surface for compaction. The CC522HF applies significant compaction forces with a high centrifugal force of 26,078 lbs and a low centrifugal force of 16,636 lbs, both at a nominal amplitude of 0.1 inches. It operates at vibration frequencies of 50 and 63 vibrations per minute, providing efficient soil and asphalt consolidation. The static linear load is 460.9 pounds per inch, ensuring strong compaction intensity over the drum width. This smooth drum roller’s articulation and vibration system are engineered to optimize compaction uniformity and efficiency on medium to large projects. Its powertrain and structural design balance maneuverability and compaction force, making it suitable for paving and base layer work where smooth and even surface compaction is critical. The CC522HF’s specifications reflect its role as a reliable, high-performance roller in heavy construction environments.
