The Dynapac CC224 HF is a high-frequency static smooth drum roller designed for efficient compaction in asphalt and other construction applications. It features dual smooth drums each 59 inches wide and 45.3 inches in diameter, providing excellent surface contact and compaction uniformity. Powered by a Cummins QSB3.3T3 diesel engine delivering 99 hp (74 kW) at 2200 rpm, the CC224 HF balances strong performance with fuel efficiency, achieving up to 24% lower fuel consumption compared to its predecessors. The machine’s maximum operating mass is 19,841 lb (9000 kg), with the operating mass including ROPS at 16,975 lb (7700 kg). Its compact design includes an overall width of approximately 4.9 ft and a tight inner turning radius of 1.4 ft, enhancing maneuverability on varied job sites. The roller operates at speeds up to 7.5 mph (12 km/h) and delivers vertical oscillation of ±7° to accommodate uneven surfaces while maintaining ground contact. The drum shell thickness is robust at 0.79 in (20 mm), supporting durability in demanding conditions. Additionally, it features a double pump vibration system with vibration frequencies between 50 to 67 vibrations per minute to ensure optimal compaction. Its height ranges from 7.46 ft without ROPS to 9.8 ft with ROPS/cab, length is 14.73 ft, and outside turning radius is 21.56 ft, making it versatile for various paving and compacting projects. This model delivers efficient, reliable performance with advanced control and ease of use for professional compaction tasks.
