DYNAPAC CC4200C VI STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CC4200C VI is a high-performance smooth drum roller designed for efficient compaction on granular and mixed soils. It features a robust Cummins QSF3.8 IV water-cooled turbo diesel engine with aftercooler, delivering 130.1 hp at 2200 rpm and meeting Tier 4f emissions standards. The machine offers hydrostatic service braking in both forward and reverse and a failsafe multidisc parking brake integrated into drum and wheel motors for reliable stopping power. Its compaction drum is 66 inches wide and 51 inches in diameter, with a thickness of 0.8 inches, generating centrifugal forces of 18,880 lbs (low) and 28,780 lbs (high) with a nominal amplitude of 0.1 inches at vibration frequencies of 51 and 67 vpm, ensuring uniform and effective soil compaction. It possesses a static linear load of 167 pounds per inch, contributing to efficient downward force distribution. The CC4200C VI has a maximum speed of 7.5 mph, a gradeability of 41%, and curb clearance of 32 inches, making it capable of working on slopes and varying terrains. Its overall dimensions include a length of 197 inches, width of 6.3 feet, height to the top of the cab at 9.9 feet, and turning radii of 18.4 feet inside and 23.9 feet outside, enhancing maneuverability. The operating weight is 24,300 lbs, supported by a 143-gallon water spray system for drum wetting to prevent soil adhesion. Steering offers a 32-degree angle, and an oscillating articulation angle of 7 degrees improves ground contact on uneven surfaces. Fuel capacity is 48 gallons with a 4-gallon DEF tank for emission control.
