The Dynapac CC222CHF is an articulated tandem static smooth drum roller designed for high-performance compaction of asphalt and base layers. It features a robust, well-balanced design with articulated steering and pivotal rear drum steering, enabling up to 500 mm of offset for exceptional maneuverability in tight or complex work areas. The machine is equipped with a Deutz air-cooled turbo diesel engine, model BF4L, delivering 80.5 hp (60 kW) at 2,800 rpm, providing reliable power for continuous operation. It has a maximum operating speed of 6.9 mph (10 km/h) and a hydrostatic drive system with axial piston pumps and radial piston motors for smooth, efficient traction in both forward and reverse. The CC222CHF has a front drum diameter of 44.1 in (3.7 ft), a drum width of 57.1 in, and an operating weight of 15,829.2 lbs, resulting in a static linear load of 163 lb/in for consistent, high-quality surface finish. It offers two vibration frequencies (54 and 71 vpm) and two amplitude settings (high and low) to match varying material types and layer thicknesses. The hydraulic system includes separate circuits for driving, vibration, and steering, with a failsafe multi-disc parking/emergency brake on drum and wheel motors. With a ground clearance of 10.7 in, overall width of 4.6 ft, and compact dimensions, the CC222CHF is ideal for a wide range of road construction and maintenance applications.
