Four new tandem asphalt rollers, the 8- to 10-ton Dynapac CC224HF and a split-drum version CC234HF and 10- to 12-ton models CC324HF and split-drum CC334HF, extend Dynapac’s range in the 8- to 12-ton class to six models.
Four new tandem asphalt rollers, the 8- to 10-ton Dynapac CC224HF and a split-drum version CC234HF and 10- to 12-ton models CC324HF and split-drum CC334HF, extend Dynapac’s range in the 8- to 12-ton class to six models. “Soft” starting and stopping prevent bowing or cracking in the asphalt layers, allowing even unskilled operators to start and stop without leaving marks. The machines automatically drop out of the “soft” mode and brake immediately if the lever is moved quickly, signaling the need for an emergency stop. A double-pump vibration system eliminates need for a vibration valve, making the system more efficient and aiding servicing while reducing fuel consumption. The new Dynapac models are powered by a Cummins QSB 3.3 T3 water-cooled turbo engine with after cooler and rated at 80 horsepower at 2,200 rpm. A 99-horsepower engine is also available.
