Seismic Soil

Compaction Redefined

With a Sesimic Soil machine you benefit from high-quality results, increased productivity, energy- and cost efficiency as well as operator comfort and simplicity. This Seismic innovation by Dynapac is unique and is the only system on the market that is completely automatic with no need for additional operator training. 
 


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 quiter, 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.

Seismic Soil automatically adjusts the vibration frequency based on the soils characteristics

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 prevents issues like bouncing and aggregate crushing. This fully automatic compaction process eliminates operator guesswork, ensuring optimal performance for any material or layer type.
 

 


Seismic Delivers More

EcoMode

With the EcoMode setting enabled, the machine operates at the lowest possible RPM without compromising compaction quality. The machine automatically idles after 10 seconds in neutral, significantly reducing engine RPM. This feature does not interfere with the general workflow or operation of the machine and ensures instant start-up after idle mode.

Compaction Meter

The Dynapac Compaction Meter provides real time stiffness measurements to ensure optimal compaction. The compaction meter can present three unique values for the operator, CMV, EVIB1 and EVIB2 – the closest representation to density levels available on the market today. Seismic Soil uses the Compaction Meter Sensors to calculate the frequency adjustment

Active Bouncing Control

To help prevent damage, extend the roller’s lifespan, and ensure better compaction results, you can use Active Bouncing Control. The system works by detecting when the soil becomes very stiff and can no longer absorb energy, which causes harmful bouncing. First, it warns the operator when bouncing is detected. Then, it automatically stops the vibrations and instructs the operator to reduce the amplitude. Finally, the system fully shuts down the vibrations.
