Dynapac

Excellent Operator Comfort

The machine operates at a lower noise level and transmits fewer vibrations to the cab, thanks to reduced frequency levels. This results in a more pleasant experience for the operator, allowing you to enjoy your workday in a quieter, smoother, and more comfortable cab.

 

Select and go

Starting a machine with Seismic is incredibly simple, as Seismic is automatically activated by default. Just pick high or low amplitude. That’s it. You’re ready to roll.

Thanks to lower frequency vibrations, the improvement is evident both inside the cab and in the area around the machine. You get a calmer, more comfortable workspace that enhances both focus and overall operator well-being.

How the System Works

The system provides real-time monitoring and continuously adjusts the frequency automatically based on the material. No additional training is required and no risk of getting the compaction settings wrong. By working in harmony with the material being compacted, it significantly reduces issues like bouncing and aggregate crushing. This fully automatic compaction process eliminates operator guesswork, ensuring optimal performance for any material or layer thickness.
 

Reduces Wear and Tear

Thanks to Seismic and the optimised frequency adjustments, the vibration powertrain and drum shell are exposed to less stress and wear compared to conventional compaction. This, in turn, means a longer life of the vibration mechanism and related hydraulics. On top of this, Dynapac's already durable and thick drum shells will last even longer, maximising the drum lifetime.

Scientifically Proven

With Seismic Soil, operators can reduce the number of compaction passes by up to 30%, delivering faster results with lower fuel use and reduced operating costs.
These benefits are backed by repeated testing, including studies from KTH Royal Institute of Technology and VTI (Swedish National Road and Transport Research Institute), which confirm that Seismic Soil technology increases compaction efficiency while also lowering environmental impact.
