Split Oscillation and VIO compaction meter
Renowned as a pioneer in efficient and intelligent oscillation compaction, HAMM continues to develop this technology. At Bauma 2019, the manufacturer is presenting two exciting innovations: a split oscillation drum and the VIO compaction meter for oscillation. HAMM has also further optimised the drive concept for the oscillation drums, making the next generation of oscillation drums completely maintenance-free.
Two times oscillation in one drum
Alongside the split vibrating drums, HAMM now also offers split oscillation drums, which combine the benefits of oscillation with the added value of a split drum. Oscillation enables these drums to deliver excellent results for compaction on bridges, of thin layers, in vibration-sensitive areas or at critical temperatures. Thanks to their split drums, they are ideally suited to challenging tasks such as compacting difficult-to-compact asphalts and curved sections.
Developed and patented by HAMM, this premium solution is the only one of its kind on the market. It can be seen in the at Bauma 2019. A separate, mechanically-independent oscillation unit operates in each half of the split oscillation drums. An integrated control mechanism adjusts the rotational speeds of each half of the drum to match one another. The synchronisation is done electrohydraulically. Because the system reacts quickly and precisely, synchronous vibration in each of the two drum halves is guaranteed in any situation. This reduces the danger of cracks in or displacement of the asphalt, and is ultimately a great advantage in terms of quality.
World premiere: Compaction measurement for oscillation
With the world's first VIO compaction meter, HAMM is expanding its range of modules for compaction measurement and documentation at Bauma 2019. HAMM is thus the only manufacturer offering the ability to measure compaction in oscillation mode. This means that HAMM rollers can document their passes in a traceable way, even for continuous dynamic compaction control applications with oscillation. The system is already available for the .
