Dynapac’s CA3500D SEISMIC soil curler is efficient in general compaction in addition to saving gas on the job web site – a truth confirmed by unbiased testing by the Swedish Nationwide Street and Transport Analysis Institute (VTI).

The CA3500D is designed to provide quick, cost-effective compaction, utilizing the distinctive and clever SEISMIC expertise which robotically permits the curler to find out the optimum frequency for any materials to be compacted. An onboard machine management unit and next-generaiton compaction meter make it attainable for SEISMIC to sense the dynamic traits of the fabric and calculate optimum frequency required for the perfect compaction outcomes. Superior knowledge move from the SEISMIC compaction meter to the onboard machine management unit, which regulates the machine’s hydraulics, guides the machine in making use of the correct quantity of vitality precisely the place and when it is wanted. Vibration frequency may be modified as usually as each 0.2 seconds to supply most efficiency.

On the identical time, this curler is ready to cut back gas prices on the job web site because of larger effectivity. Testing by VTI reviewed gas consumption in three completely different settings over a interval of two weeks. The CA3500D SEISMIC has three engine settings – Customary, with excessive RPM and vibration frequency at 29Hz in excessive amplitude and 33Hz in low; Eco, with decrease RPMs robotically adjusted to the engine mode; and Eco + SEISMIC mode, with a decrease RPM managed by the Eco setting and computerized changes made to vibration frequency.

VTI discovered a gas consumption discount of 28 to 35 p.c, in comparison with standard compaction (fastened frequency). In addition they famous an excellent alignment with onboard telematics, which reported financial savings of 36 to 38 p.c. Thus, beneath actual job web site situations, there’s an general financial savings of round 55 p.c.
