CORE COMPETENCE COMPACTION TECHNOLOGY HAMM OSCILLATION: THE INNOVATIVE SOLUTION FOR ALL APPLICATIONS IN THE FIELD OF SOIL AND ASPHALT COMPACTION
In the oscillation drum masses turning in the same direction, produce one moment around the drum axle. The ment changes its effect direction during a turn of the mass (forward and reverse), so that the oscillation drum movement is created.
Here thrusts are introduced into the soil. With oscillation clearly lower resonances are generated than with the vibration. It only causes up to 10% of the stress exerted by vibrating compactors. Oscillating rollers do not “use up” their energy to create undesired vibration of the surroundings but transmit it purposefully into the material to be compacted – exactly where the energy is needed. On all bitumen job sites – from the smallest surface, bridges, multistorey car parks up to highways – the oscillation shows its performance and clear advantages. The oscillating movement in combination with the permanent static load of the drum guarantee a fast increase of compaction together paired with very homogeneous compaction and good surface roughness. The sub base remains thereby preserved. Hamm For earth compactors there is also the possibility for the oscillation compaction, here is the VIO drum used. In this drum both systems are combined, so that there can be selected between oscillation and vibration.
