New models HC 119 and HC 129 for earthworks

Modern compaction technology – powerful and economical: With its HC series, HAMM presents new compactors in every weight class for all markets. Based on a shared platform, HAMM meets the requirements of regional markets through different versions. The HC 119 and HC 129 models are designed specifically for Southeast Asia, Africa, the Middle East and Latin America. They bring ample power to the construction site, but thanks to the ECO mode, they are significantly more economical than their predecessors. Furthermore, they offer a modern and comfortable operator's platform and excellent driving and handling characteristics.

One platform for all markets

HAMM has developed the new HC series on the basis of a standardised platform and supplies models worldwide starting at 11 t operating weight. In this regard, the manufacturer is merging the compactors of the existing 3000 series and H series. The drum width on all models is 2140 mm.

Optimum compaction performance

The high static linear load of the compactors means they can be used anywhere, for infrastructure projects in road construction, at airports and other large areas. The powerful Cummins engine ensures that maximum compaction force is always available, and the vibration works immediately once the nominal frequency is activated. HAMM fits all models with drum drive. As an optional extra, an automatic vibration system can be integrated. It switches off the vibration as soon as the compactors are at standstill. This prevents over-compaction and guarantees high-quality surfaces. For compacting cohesive soils, HAMM also offers the option of padfoot shells. Additionally, all models can be fitted with a HAMM Compaction Meter (HCM). This highlights weak points and helps to prevent over-compaction.

Clear operation, comfortable workstation

HAMM is initially supplying the compactor with an open platform. All models include a protective roof as standard to shield operators from sun and rain, and also feature ROPS/FOPS as standard. The operation is self-explanatory and does not require any special language skills. From the operator's platform on the new compactors, the driver has an excellent view of the construction site. Thanks to the design of the engine hood and the front vehicle, the driver can always keep the drum and the construction site in view. As standard, a USB socket, 12 V socket and a bottle holder are included on board. This equipment and other features turn the roller operator's platform into a comfortable workstation. Bright work lighting with durable LED lights rounds off the high-quality and environmentally friendly overall picture. Provisionally from the first quarter of 2023, HAMM will also offer models with ROPS/FOPS cabs.

Efficient ECO mode

The HC 119 and HC 129 models are driven by a robust and powerful water-cooled 82 kW 4-cylinder engine in accordance with regional requirements. The engine can be operated with pure diesel or with B20 fuel, up to 20% of which is derived from biological sources. Whichever fuel is used, two fuel filters and one additional water separator ensure reliable operation. The compactors work ultra efficiently in ECO mode. In this mode, the speed is reduced but the vibration frequency and the centrifugal force – and therefore the entire compaction power – are constantly maintained. This is made possible by the generously proportioned hydraulic components combined with an intelligent control system. Fuel consumption is still reduced by up to 20%. Consequently, the CO2 emissions and noise emissions are reduced too. The compactors are able to be used at outside temperatures of up to 52 °C thanks to a newly designed air duct and a large radiator.

Great driving and handling characteristics

The 3-point articulation in the new compactors guarantees outstanding directional stability, impressive stability when negotiating curves, and a high level of safety against overturning. This means that the compactors ensure safe manoeuvring and highly efficient compaction, even on rough terrain. The front vehicle boasts a large slope angle, so that even steep inclines can be overcome with ease. A differential lock on the rear axle of the compactors ensures good traction for climbing – even on challenging substrates or steep terrain – and, at the same time, reduces the wear on the tyres.
