The HP series ballasting concept at a glance:
The basis for ballasting the models from the HP series is the two large ballast spaces between the wheelsets. Here, pre-made ballast bodies made of steel, heavy concrete or concrete can be inserted or removed using a forklift truck, for instance. A range of precisely manufactured ballast bodies are available ex works. Optionally, HAMM offers a model with a ballast space measuring 2 m3 for both markets. This can be used for self-ballasting (e.g. using scrap or sand). The ballast space can be filled with this material via filling openings on the right and left of the machine. For all models in the HP series, there is also an optional additional water tank with a volume of 1,500 litres. This can be used as a water reservoir to supply other rollers, as an extension of the regular water tank for tyre sprinkling or as additional weight. For models in the HP series, this means that the weight of the basic machine can be adjusted by up to 10 tonnes (HP 180, HP 180i) or 18 tonnes (HP 280, HP 280i).
