High Performance Compaction Through HAMM Oscillation Technology
Hamm's new, unique, non-aggressive Oscillation technology is a completely different type of Hot Mix Asphalt compaction that is exciting contractors across the continent!
Hamm's new Oscillation technology is non-aggressive because it compacts with a gentle rocking motion, not a vertical pounding. It's a powerful new tool for boosting your asphalt paving productivity and profits. And it's available NOW from Hamm.

Hamm has developed a principle of creating compactive effort through generating horizontal shear forces, as opposed to vertical amplitude. Instead of driving straight up and down, Hamm Oscillatory design gives the drum a horizontal or "rocking" force. This is significantly different from competing manufacturers, and is an example of how Hamm moves technology, research and design to new levels.

Unlike traditional vibratory compactors that achieve compaction by "bouncing" the drum on the ground, Hamm's Oscillation technology ensures that the roller drums maintain constant contact with the ground for faster, more effective compaction.
In the oscillation drum, two eccentric masses turning in the same direction cause a movement around the drum axle. The movement changes its direction of effect during one turn so it generates an oscillating or rocking movement of the drum. Horizontal forces are transmitted from the drum into the pavement. The result is better compaction in fewer passes, with less vibration-related wear and tear on operators and surroundings.
 |
Not only will Hamm's Oscillation technology compact faster, but it compacts more gently. That's of great use for compaction on bridge decks, concrete floors, as well as for hot mix asphalt mats on previously compacted subbase or asphalt mats. Over 10 years ago Hamm developed the first Oscillatory rollers for use overseas. Now this revolutionary technology is available to you in North America.
