Hamm models that incorporate the company's oscillating technology include the HD 070V, HD 090V, HD 0120V and 3412 VIO asphalt rollers. These machines have a conventional vibratory system on the front drum, but use Hamm's oscillating drum at the rear. According to Hamm, the compaction effort of the rear drum is "non-aggressive" because it compacts with a gentle rocking motion. The rear drum develops its compaction effort via generating shear forces, as opposed to vertical forces (amplitude) and, says the company, machines using this technology may achieve compaction up to 62 percent faster that conventional vibratory machines.
