Dynapac drives increased asphalt compaction efficiency

Dynapac claims high compaction efficiency for its revamped 8tonne CG2300 twin-drum asphalt roller, as well as the new CG3300 machine for the 9tonne class. Both models now benefit from the firm’s VI technology, with a key feature being the addition of the innovative SEISMIC system first developed for the company’s soil compactors.

Among the features of the new Dynapac CG3300 VI are its latest generation VI operating station, interface, electric system, and ECU software. Additionally, the Dynapac CG3300 VI will come with a new style for forks, beams, and frames.

After comprehensive testing and adjustments to a hot asphalt mix, similar results were achieved with the novel SEISMIC technology in asphalt compaction as those for soil compaction. Benefits include reduced vibration power and energy consumption by 20-30%, and a 7-9% fuel consumption reduction.  

Additionally, noise levels are lowered due to lower frequency and there was an overall reduction in the number of passes depending on the application. The generation VI CGs will also be available as combi versions with a split drum front and rubber wheels rear.

The new operator station for the CG3300 VI station offers full seat rotation, making it possible to turn the seat and steering module all the way around for visibility. The machine has an electric steering wheel and an instrument panel that is said to be easy to understand.

The patented Efficiency Eccentrics system optimises eccentric elements, providing further fuel and energy savings during operation. The included ECO-mode, with its best point system and serial start-up, helps ensure lower emissions.

The CG3300 VI has a length of 4.2m, with a 1,680mm drum width, 1,200mm offset, and an operating weight of 9tonnes. It comes with a static linear load of 26.8kg/cm. The CG3300 VI also comes with the Dyn@Link advanced system, which keeps track of parameters and operating processes.
