DYNAPAC CC324HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC324HF is a high-performance static smooth drum roller designed for efficient compaction in asphalt and other applications. It features a Cummins QSB 3.3 T3 diesel engine delivering 74 kW (99 hp) at 2200 rpm, enabling robust power and reliability. The roller has an operating mass of 18,188 lbs (8,250 kg) including the cab, with a maximum operating mass of 20,834 lbs (9,450 kg). It offers a drum width of 68 inches (1.73 m) and an overall operating width of 73 inches (1.85 m), with a drum diameter of approximately 3.77 feet (1.15 m). The inside turning radius is 195 inches (4.96 m), providing excellent maneuverability on job sites. The CC324HF features dual vibration frequencies—2870 vpm and 4010 vpm (48 Hz/67 Hz)—with nominal amplitudes of 0.024 in (0.6 mm) and 0.008 in (0.2 mm) for high and low amplitude settings, respectively. Corresponding centrifugal forces range between 17,310 lbf and 20,233 lbf (77 - 90 kN) at high amplitude, ensuring effective soil and asphalt compaction. It operates at speeds up to 7.46 mph (12 km/h) and has a maximum theoretical gradeability of 37%, suitable for various terrain conditions. The fuel tank capacity of the roller is 34.3 US gallons (130 liters), supporting extended work cycles. Transport dimensions include a length of 14.73 ft (4.49 m), width of 6.07 ft (1.85 m), and height with ROPS/cab of 9.81 ft (2.99 m). This combination of power, precision vibrations, and compact design makes the Dynapac CC324HF ideal for contractors requiring controlled, high-quality compaction performance in medium to large asphalt paving projects.
