NEW MODELS ADDED TO TANDEM ASPHALT ROLLER LINE
A new 7 to 8 t class tandem asphalt roller, the CC224HF, together with the split-drum version CC234HF, are introduced by Dynapac extending the recently introduced new generation of articulated tandem rollers. In common with the larger models, the CC224HF and CC234HF have been designed to meet the needs of contractors, road contractors and rental companies worldwide. New features simplify and speed servicing so as to guarantee maximum availability. Use of a double pump vibration system eliminates the need for a vibration valve, making the system more efficient, aiding servicing and reducing fuel consumption. Both pumps - one for the front drum and one for the rear - can simply be shut off.
The new models are powered by a Cummins QSB 3.3 T3 water-cooled turbo engine with after cooler and rated at 60 kW (80 hp) at 2200 rpm. Also available is a 74 kW (99 hp) engine. Dynapac's automatic engine idling system cuts the idling speed after 10 seconds at full rpm in neutral to further reduce emissions, provide additional fuel savings and minimise noise.
The new CC24HF split-drum version ensures easier steering around corners in congested areas without ‘shearing’ the asphalt.
One of the ways of achieving high quality compaction is to optimise the ergonomics, ensuring that operators have continuous visibility of the operation and comfortable access to the controls. All machines will feature 1 x 1 m view and full visibility over all working functions.
