DYNAPAC CC385HF STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC385HF is a high-performance static smooth drum roller designed for efficient asphalt and soil compaction applications. It features a 68.2-inch wide, 45.3-inch diameter double drum with a thickness of 0.7 inches, delivering a high centrifugal force of 20,233 lbs on the high amplitude setting and 16,861 lbs on low, both at a nominal amplitude of 0.1 inches. The static linear load is 152.4 pounds per inch, providing strong compaction pressure across the drum width. Powered by a Kirloskar 4R1040TA3 water-cooled, turbocharged, and intercooled engine, it produces 105 horsepower at 2200 rpm and supports an operating weight of up to 23,589.5 lbs. The roller achieves a maximum travel speed of 7.5 mph and maintains gradeability up to 37%, enabling it to work efficiently on slopes. Dimensionally, it measures approximately 177 inches in length, stands 9.9 feet tall to the top of the cab, and offers a turning radius of 17.5 feet. The machine includes a 198.2-gallon water spray tank for drum wetting to prevent asphalt sticking and features a turning angle of 32 degrees and a 7-degree oscillating angle, enhancing maneuverability. Ground clearance is 10.7 inches with 28.2 inches curb clearance. The fuel tank capacity is 54.2 gallons, enabling extended operation. Overall, the Dynapac CC385HF combines robust engine performance, precise compaction force, and user-friendly handling for medium to large road and construction compaction tasks.
