Hamm is presenting four newly-developed oscillatory rollers at bauma 2013. It means that the roller manufacturer is offering this environment-friendly and cost-effective compaction technology not only for medium and heavyweight tandem rollers and compactors, but also for the successful articulated rollers in the HD CompactLine.
It means that the roller manufacturer is offering this environment-friendly and cost-effective compaction technology not only for medium and heavyweight tandem rollers and compactors, but also for the successful articulated rollers in the HD CompactLine.
The new range includes the Hamm HD 10C VT combi roller, which makes its debut at bauma.
The smallest combi roller in the CompactLine, with a working width of 1.06m and operating weight of 1.5tonnes, comes with permanent all-wheel drive as standard, in common with the tried and tested HD 8 and HD 10C tandem rollers. This distinguishes it from all other compact rollers in this size and gives it outstanding climbing ability in all situations.
Hamm dominates the compact tandem roller market segment worldwide with the HD CompactLine. Now with a total of 16 models, it is the largest model range in the sub-4.5tonne weight category on the market.
The advantage of oscillation is that it achieves a very fast increase in compaction because the drum’s direct tangential thrusting forces into the material to be compacted while remaining constantly in contact with the ground. The combination of continuously acting static load and changing dynamic shear forces in the material bring about a faster, better and more gentle compaction.
With the construction of oscillatory rollers in this weight class, Hamm is responding to the increasing demands for high-quality compaction even in extremely small areas. Oscillation increases compaction speed and quality.Applications can be found in urban centres for example.
Up to now, tandem rollers have only been able to operate in static mode on narrow construction sites. In future, oscillatory rollers will compact dynamically, on account of the fact that oscillatory compaction does not disturb buildings or pipework below the road surface through vibration. At the same time, a better compaction result is achieved faster.
