For pneumatic tyre 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 tyre pressure and roller speed, is key to compaction force and depth.
HAMMTRONIC is an electronic machine management system that monitors and controls all key machine functions, thereby 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 programmes (for DV+ series only), guaranteeing even, smooth movement of both drums.
