The Dynapac CC Line series of eight double-drum and eight combi tandem asphalt rollers includes: CC224HF, CC234HF, CC324HF, CC334HF, CC384HF, CC424HF, CC524HF, and CC624HF dual-drum models; CC224CHF, CC234CHF, CC324CHF, CC334CHF, CC384CHF, CC424CHF, CC524CHF, and CC624CHF combis with a drum roller and rear set of pneumatic tires.
Rollers have the DCA-A Compaction Analyzer that monitors and records key parameters via a GPS-assisted, graphic, real-time display of temperature and number of passes.
They feature high frequency/low amplitude for thin layers and high amplitude for thick layers. The articulated tandem rollers are powered by a Cummins QSB 4.5 water-cooled turbo-diesel engine with after cooler. The rated power is 125 hp at 2200 rpm for the CC424HF, and 152hp for the larger CC524HF and CC624HF models. The new machines have operating masses ranging from 11.6 tons to 13.9 tons. The weight is split evenly between the front and rear drum modules.
The machines feature a double-pump vibration system, which eliminates the need for a vibration valve. This feature is designed to make the system for efficient, aid in the servicing, and reduce fuel consumption. Fuel consumption is expected to be further reduced because there are fewer number of hydraulic hose fittings, proportional control of cooler fan speed used for engine coolant and hydraulic oil temperatures, and automatic diesel engine idling after 10 seconds in neutral.
