HAMM's pneumatic-tyre rollers combine innovation and productivity


The new generation of pneumatic-tyre rollers from the HP series have been on the market across the world for several months and are showing what they can do in practice, according to the Wirtgen Group


The range of potential applications extends from soil stabilisation, cold recycling and landscape gardening, tight through to final compaction and surface sealing in asphalt construction.

For the HP series, HAMM has developed a uniform platform as the basis for all model variants in every market. Based on this, the company is also continuing to offer the pneumatic-tyre rollers in different basic versions. There is the HP 180 or HP 180i model, with operating weights between 8 and18 tons, and the HP 280 or HP 280i model, with working weights between 10 and 28 tons. In doing so, HAMM provides the individual markets with the respective model to suit their regional demands with regard to weight classes and equipment versions.

 Simple and intuitive operation is extremely important to the driver, along with the ergonomically optimised driver's platform. When combined with the shape of the asymmetrical frame, this results in perfect visibility. 

 The HP series' powerful, hydrostatic rear-axle drive, combined with a senstivie control system, allows the right speed to be set in every working situation. The intelligent drive control also allows for smooth, even acceleration and braking, which prevents uneven compaction. 

 HAMM offers a wide range of options for the HP series, so the pneumatic-tyre rollers can be perfectly equipped for each individual market and application. The thermal aprons have always been a classic piece of equipment for the pneumatic-tyre rollers and they are available for all models in the series. The diesel-powered tyre heating is a new feature for the HP 180i and HP 280i models, with the advantage that the heating is not operated using gas, but rather with diesel from the fuel tank. This eliminates the costly transport and time-intensive replacement of the cylinders.

 Innovative additive-sprinkling system

 When paving special asphalt that is difficult to process, the sprinkling of the pneumatic tyres with additive is essential for high-quality compaction. By completely redesigning the additive-sprinkling system, HAMM is creating optimal prerequisites for easy handling and the highest level of compaction quality. The system offers a time-saving advantage whereby no premixing is required. The water and additive are mixed automatically, which guarantees a lasting optimal mixing ratio.
