This intelligent technology allows the roller to determine the optimum frequency for any compacted material automatically. An onboard machine control unit and next-generation compaction meter work together to allow the SEISMIC system to sense dynamic characteristics of the ground and calculate the optimum frequency for compaction. The process uses advanced data flow from the SEISMIC Compaction Meter to the onboard machine control unit, which regulates the hydraulics. SEISMIC technology automatically detects the resonant frequency of the soil. This system automatically applies the correct compaction forces exactly where required and can hydraulically change the drum frequency, every 0.2 seconds for maximum performance. As the drum no longer randomly hits the soil, it achieves precision and efficiency while saving time and fuel.
The system increases job-site productivity while reducing the number of passes required and eliminates the risk of over- or under-compaction. Fuel consumption can be reduced by up to 55%, while productivity can be boosted by up to 40%. Due to lower frequencies, noise levels are also reduced while operating at lower frequencies also helps to reduce maintenance needs for the machine.
The SEISMIC feature is now available for Dynapac soil compactors ranging from the 7tonne CA1500 to the 21tonne CA6500 model.
