35 years of quality and oscillation experience in HAMM Rollers

35 years of quality and oscillation experience in HAMM Rollers

For more than 35 years, HAMM has included oscillation rollers in its product range and with over 35 models; it offers by far and away the widest diversity in the world. A glance at the constructive realisation of the technology reveals the decades-long experience in the manufacture of oscillation rollers. They stand out for their resistance to wear, compaction quality and ease of maintenance.

Experience shows

When building oscillation drums, HAMM – unlike its competitors, which have all entered the market with this technology in recent years only – can draw on decades of experience. And it is precisely this experience that makes the difference, as Head of Marketing Gottfried Beer explains: “You can copy technical solutions, but you can’t copy experience.”

Thanks to its wealth of experience, HAMM possesses extensive know-how in application technology. This knowledge is not confined to a few specialists in the factory, but extends to the subsidiaries all around the world. Due to the large number of oscillation rollers on the market, spare parts availability is also very high. In addition, the service engineers all over the world are thoroughly familiar with the technology and trained with regard to oscillation.

Maximum wear resistance

A big advantage of the HAMM oscillation drums lies in the high-quality drum shell. It is inevitably subject to greater stresses than is the case with vibrating drums, due to the uninterrupted ground contact. Thanks to ongoing product and material development, the operating life of HAMM oscillation drums is today nearly the same as that of vibrating drums. This is made possible by using highly wear-resistant fine grain steel for the drum shell. In addition, the material thickness is more than 50% greater than that of comparable competitive machines. In addition, an integral reinforcing ring ensures that the drum is extremely hard-wearing. This is why HAMM confidently provides a remarkable warranty against wear of at least 4,000 operating hours. With this warranty, the Tirschenreuth manufacturer surpasses any other serious offer on the market by a wide margin.

Quality thanks to chamfered drums

To ensure that the drums leave no impressions in the still soft asphalt, especially in curves, HAMM gives all drum edges a slight chamfer. Impressions of this nature have to be re-rolled afterwards, wasting time. Otherwise, they remain visible in the asphalt and compromise quality. Both issues are avoided from the outset thanks to HAMM’s design solution. By the way: this chamfer can also be found on all of HAMM’s vibrating drums. A small yet effective detail that ensures top quality.

Low-maintenance operation

A glance at the exciter system drive inside the oscillation drum also shows that it is based on a great deal of experience. HAMM has continuously optimised the position of the unbalance weights in the oscillation drum to enable the resulting forces to be utilised as effectively as possible.

At the same time, HAMM’s oscillation drums are designed to require very little maintenance. The toothed belt, the core element of the drive, has been perfectly attuned to the overall system: its operating life corresponds to that of the entire drum. Checking the belt tension after 2,000 operating hours is all that is recommended.
