DYNAPAC CC384 HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC384 HF is a high-frequency static smooth drum roller designed for efficient soil and asphalt compaction. It features a drum width of 68 inches (1.73 meters) and an operating width of 76.4 inches (1.94 meters), providing a broad compaction surface for advanced productivity. The roller has an operating mass of approximately 9,400 kg (20,723 lbs) with ROPS and 9,600 kg (21,164 lbs) with a cab, reaching a maximum operating mass of 10,700 kg (23,590 lbs), enabling strong compactive force and ground contact. It is powered by a Deutz TCD 3.6 IIIB/T4i water-cooled turbo diesel engine delivering 75 kW (100 hp) at 2,200 rpm, with an alternative Cummins engine option available. The CC384 HF offers a variable speed range from 0 to 12 km/h (0 to 7.5 mph) and a maximum theoretical gradeability of 37%, allowing efficient operation on varied terrains and slopes. The drum vibrates at dual frequencies of 2880 and 4020 vibrations per minute to enhance compaction efficiency. The machine’s compact dimensions include a transport length of 4.49 m (176.8 in), width of 1.94 m (76.4 in), and height of 2.99 m (117.7 in), while its turning radius inside measures 195 inches (495 cm), facilitating maneuverability on constricted job sites. This roller incorporates hydrostatic drive, failsafe multidisc brakes in both drums for safety, and a robust hydraulic system for drum vibration and steering control, making it suitable for medium-scale compaction projects requiring precision and reliability.
