Hamm is expanding its HC Series with the HC 130i C VA compactor that enables automatic compaction to a target value by working with Smart Compact.
The new 13-tonne model joins the 20 and 25 tonne HC 200i C VA and HC 250i C VA in the roster.
The HC 130i C VA compactor is equipped with the new variable amplitude (VA) drum that enables automatic compaction depending on the ground conditions and machine capacity. The VA technology ensures homogeneous compaction and increases cost-effectiveness by reducing the number of double passes and lowering diesel consumption. The machine meets exhaust emission standard EU Stage V and EPA Tier 4 Final.
In day-to-day work, drivers can choose between an automatic and a manual mode. In automatic mode, the amplitude is regulated by the machine control system.
In manual mode, five fixed amplitudes are available. Before compaction, the target compaction value in MN per square metre can be specified, based on typical load-bearing capacity values.
The basis for the automatic regulation of the compaction forces is the Smart Compaction Value (SCV), which is also now determined by Hamm and is continuously and precisely recorded independently of influencing factors such as driving speed, frequency or direction of travel.
Benefits for operators

The new VA compactors offer numerous advantages for operators and construction companies alike. Automatic adjustment of the amplitudes not only ensures homogeneous compaction but also effectively prevents over-compaction and particle crushing at the same time. These features make the new VA compactors a suitable choice, even for less experienced operators.
As well, the cost-effectiveness of construction projects is improved by the reduced number of double passes, which leads to lower diesel consumption and less mechanical stress on the machines. Furthermore, making fewer double passes translates into a reduction of carbon dioxide emissions.
The machine control system reliably prevents jump operation, contributing to a longer service life of the machines. The direct adjustment of the amplitude makes the VA technology an energy-efficient system overall.
