New HC Series soil compactors for defined markets

Efficient compaction and future-proof design

In summer 2023, Hamm will launch new models of its UN ECE R96 (Tier 3)-compatible soil compactors. A total of six new HC Series models will be introduced, namely the HC 208 D, HC 208 P, HC 228 D, HC 228 P, HC 268 D, and the HC 268 P, each with a weight of either 20 t, 22 t, or 26 t. All these soil compactors are equipped with a powerful 154 kW engine (UN ECE R96, Tier 3) and the Hammtronic electronic machine management system. They combine high compaction quality with easy operation and maintenance. Moreover, there are several optional features available, so customers can select machines that match their requirements. Low maintenance costs and low fuel consumption ensure cost-effectiveness. The new Hamm compactors can be used for a wide range of stabilization, earthworks, and CBT applications, compacting different types of material. The soil compactors will be available in defined markets in Southeast Asia, Africa, and the Middle East.

German-Chinese co-production

Since 2014, Hamm soil compactors have been produced in the Wirtgen factory in China. For the new models, a German-Chinese engineering team has combined numerous distinctive features that are typical of Hamm, such as modern design, unique visibility, first-class handling, and compaction performance with the specific needs of the various regional markets. The resulting soil compactors stand out with their modern technology, high productivity, and quality compaction. They embody German quality standards at a very attractive price-performance ratio. Furthermore, Hamm offers several optional machine features.

Reliable engine and unique cooling system

To achieve excellent compaction performance, all new models use a highly efficient Cummins engine with a rated output of 154 kW. The engine complies with the UN ECE R96 (Tier 3) specifications and is fuel-efficient. The innovative cooling system, in which the cooling air is drawn in from behind the operator’s platform and emitted at the rear, provides an optimized air supply and increases the lifespan of the power packs. It also prevents hot air from reaching the operator’s platform.

Ergonomic operator’s platform for higher productivity

Hamm soil compactors come with an ergonomically designed operator’s platform, offering a high degree of comfort as well as all-round visibility that allows an unrestricted view to the rear, the tires, and the surroundings for greater safety on the job site. The soil compactors can be optionally equipped with a cabin featuring heating and air conditioning. Alternatively, they are available with a canopy. In both cases, a spacious platform provides ample legroom and allows individual adjustment of the seat and steering wheel. A user-friendly operating panel features a clearly designed information display and intuitive operation using international symbols.

Displays for engine RPM and drive speed are standard equipment for the Chinese market. The Hamm Compaction Meter (HCM) for obtaining quick information on compaction progress can be added optionally. High-power LED working lights are another optional feature, generating enhanced visibility.

Drum drive and homogeneous weight distribution

All new models are equipped with a drum drive. This helps in scaling gradients of up to 61% with confidence. Moreover, the Hamm soil compactors are equipped with a 3-point articulated joint that is unique on the market and offers outstanding driving and steering characteristics, guaranteeing unsurpassed directional stability and driving comfort. The chassis design ensures homogeneous weight distribution across the drum and the wheels – even at the full steering angle. Moreover, the new soil compactors can effectively absorb impacts, even on rough terrain, and can also handle tilting when driving along curves.

Hammtronic and ECO mode support reduction of CO2 emissions

Increasing price pressure, rising fuel prices, and the need to protect the environment render efficient and economical machines indispensable. With the Hammtronic electronic machine management system and a powerful ECO mode, the soil compactors of the HC series meet precisely these requirements. Hammtronic is standard in all soil compactors of this series, enabling optimized load distribution that leads to tremendous gradeability and low fuel consumption. It adjusts the diesel engine speed to meet the power requirements of the individual drives. In addition, the efficient ECO mode generates fuel savings of up to 20% and results in reduced CO2 and noise emissions. Furthermore, these models also offer manual traction control to transfer the torque as required. As an option, customers can choose models with a differential gear for even greater traction.

Smooth drum, padfoot drum – or both

The Hamm soil compactors of the HC series offer a consistently high compaction performance, regardless of whether they are equipped with a smooth drum or padfoot drum ("P" models). Customers who need both drum types can use the optional padfoot shell kit, consisting of three components. This enables easy conversion of the smooth drum to a padfoot drum, making it ready to compact cohesive soil.

Easy maintenance

When it comes to maintenance, the new Hamm soil compactors offer a huge advantage in terms of their engine, since this is freely accessible from all sides. In addition, the key points for daily checks are located on one side of the machine, and the hood opens towards the operator’s platform via gas springs, all of which make maintenance tasks fast and uncomplicated.
