HAMM HC: Advanced engine technology and best compaction for earthworks

Since August 2021, HAMM has supplied new compactor models from the HC series to the Indian market. The machines, weighing 11t, are available with or without a drum drive. All machines fulfil the requirements of the CEV Stage IV. At 90 kW (121 HP), they bring plenty of power to the construction site whilst consuming considerably less fuel than their predecessors. Furthermore, the new compactors feature a modern, convenient operating platform, excellent driving and handling properties, as well as a highly efficient ECO mode that can reduce fuel consumption by up to 20 percent.

New premium compactors for India 

The HC 119i and HC 119i D compactors are available in an operating weight of 11,190 kg or 11,240 kg (all weights include the protective roof in each case). All the models are manufactured at the Wirtgen Group plant in Pune, Maharashtra. They are completely homologised and comply with the Indian laws and specifications in all details, from the engine and the lighting system, right through to their dimensions.

Optimum compaction performance 

With a drum width of 2,140 mm and a large static linear load, the compactors can be used universally in inner-city projects, for compaction on motorways, airports and other large areas. The powerful Cummins engine ensures that maximum compaction force is always available, and vibration works immediately once the nominal frequency is activated. For the driver, the acceleration of the vibrating unit is imperceptible. The automatic vibration system ensures that the vibration is shut off as soon as the compactors stop moving. This prevents over-compaction and guarantees high-quality surfaces.

Clear operation, comfortable workstation 

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 – as well as the construction site – in view. The roof, which is included as standard, protects the driver from the sun and rain. The operation is self-explanatory and does not require any special language skills. As standard, a USB socket, 12 V socket and a bottle holder are included on board. Thanks to this equipment and other details, the operator platform on the rollers is a comfortable place to work. Bright work lighting with durable LED lights rounds off the high-quality and environmentally friendly overall picture.

Future-proof engine with a highly efficient ECO mode 

All models are driven by a robust, water-cooled 4-cylinder engine in accordance with CEV Stage IV. The 90 kW (121 HP) power unit features two fuel filters as standard. To clean the exhaust gas, the machines are equipped with SCR and DOC. During operation, the operator can choose between three preset engine speeds. If the driver selects the average speed, the machine operates in ECO mode. This mode reduces fuel consumption by up to 20 percent, as well as lowering CO2 and noise emissions. Yet, in spite of this, frequency and centrifugal force as well as full compaction power continue to be maintained. This is enabled thanks to the large-sized hydraulic components and smart control system. Furthermore, the compactors are able to be used at outside temperatures of up to 53°C thanks to the newly designed air duct and large radiator. 

Great driving and handling properties thanks to the three-point articulation 

The three-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 deliver outstanding manoeuvrability and excellent compaction, even on uneven terrain. The compactors are driven by the rear axle. The ‘D model’ (HC 119i D) also have a drum drive that helps it to scale gradients of up to 53 percent with confidence.

Numerous options 

As optional components for ICS systems, HAMM offers a speedometer for comprehensive compaction inspection and the HAMM Compaction Meter (HCM) for continuous measurement of the load-bearing capacity. In addition, the HC 119i D can also be equipped with padfoot shells. Further options are available for lighting and the operator platform.

Convenient maintenance 

The HAMM compactors from the HC series also prove to be convenient when it comes to the daily check and regular maintenance. All access points can be easily accessed as the engine hood can be opened wide in the direction of the operator platform.
