DYNAPAC CC4200C STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC4200C is a static smooth drum roller designed for high-performance compaction tasks. It features a 51-inch diameter drum with a width of 68 inches and a robust 0.7-inch thick steel shell, delivering centrifugal forces of up to 31,280 lbs in high mode and 20,700 lbs in low mode. The drum vibrates at frequencies of 51 and 67 vpm with a nominal amplitude of 0.1 inches, ensuring effective soil and asphalt compaction. Powered by a Tier 4i Cummins QSB 4.5 water-cooled turbo diesel engine producing 130 hp at 2200 rpm, the machine balances power and emissions compliance. It has a maximum speed of 7.5 mph and an operating weight of 22,900 lbs, with the operating weight under ROPS at 20,900 lbs. The CC4200C offers excellent maneuverability with a 32-degree steering angle and an oscillating angle of 8 degrees. Safety and control are enhanced by a failsafe multidisc parking brake integrated into the drum and wheel motors, along with a hydrostatic service brake operable in both forward and reverse. Key dimensions include a curb clearance of 34 inches, ground clearance of 12 inches, overall length of 196 inches, width of 6.2 feet, height to top of cab at 9.9 feet, turning radius of 16.3 feet, and a 145-inch wheelbase. The water spray system holds 238 gallons to maintain drum moisture and prevent asphalt buildup, while the tires feature 11-inch track widths with 6-inch spacing and 18 inches of overlap. This combination of power, precision, and durability makes the Dynapac CC4200C ideal for large-scale road construction and base compaction projects.
