HP 180i Pneumatic-tire roller

For pneumatic tire rollers in the HP series, HAMM offers a flexible ballasting concept that can be used quickly and easily on construction sites. Two large ballast chambers between the wheel sets provide a foundation for ballasting. Here, pre-made ballast bodies made of steel, heavy concrete or concrete can be inserted or removed using a forklift truck, for instance. The different ballasting variants therefore allow for a high degree of flexibility when selecting the wheel load, which, alongside the inner tire pressure and roller speed, is key to compaction force and depth.

Simple and intuitive operation is becoming increasingly important for state-of-the-art construction machinery. With Easy Drive, HAMM has, therefore, developed a standardized operating concept for tandem rollers (HD+ and DV+ series), compactors (H series) and pneumatic tire rollers (HP series) that reduces complexity to a minimum and enables operators to react quickly and correctly in no time at all. Alongside its clear, intuitive, easy to learn operating concept, Easy Drive comprises a range of features that improve ergonomic, safety-related and service-related characteristics.

HAMMTRONIC is an electronic machine management system that monitors and controls all key machine functions, consequently increasing safety, economy and fuel savings. The opportunities offered by HAMMTRONIC include, for instance, automatic adjustment of the diesel engine speed to meet the power requirements of the individual drives. Moreover, HAMMTRONIC controls start-up and braking, and distributes the drive torques across the drum axis and back wheels in line with current operating data. HAMMTRONIC also controls the hydrostatic vibration drive and the various steering programs (for DV+ series only), guaranteeing even, smooth movement of both drums.
