Hamm is expanding its HC series with its 13tonne HC 130i C VA compactor. The firm says that using the sophisticated Smart Compact system, allows automatic compaction to a target value. The new model joins the 20tonne and 25tonne HC 200i C VA and HC 250i C VA models with similar technology.

The variable amplitude (VA) drum enables automatic compaction depending on the ground conditions and machine capacity. This technology is said to ensure homogeneous compaction and increase cost-effectiveness, reducing the number of extra passes and fuel consumption. The machine meets exhaust emission standard EU Stage V and EPA Tier 4f.

Drivers can choose automatic or manual mode. The machine control system regulates amplitude for the former; in manual mode, five fixed amplitudes are available. Before compaction, the target compaction value in MN/m² can be specified based on load-bearing capacity values. The automatic regulation of compaction forces is delivered by the Smart Compaction Value (SCV), which is determined by Hamm and continuously and precisely recorded independently of travel speed, frequency, or direction of travel.

The new VA compactors offer numerous advantages for operators and construction companies. Automatic adjustment of amplitudes ensures homogeneous compaction and prevents over-compaction and aggregate crushing.
