Three-point articulation
Three-point articulation is different to conventional joints due to its geometric arrangement and connection of the three individual joints and one additional connecting link between the two conventional upper joints. This allows optimum steering, excellent driving safety and maximum driving comfort.

HAMM Compaction Quality (HCQ)
HCQ comprises a number of HAMM products designed to measure, monitor, document and control compaction and compaction processes. This includes the HAMM Compaction Meter, the HAMM Temperature Meter and the HCQ Navigator. These components continue to determine the rigidity value, the asphalt temperature and the position of the roller throughout compaction. A panel PC (touchscreen) on the driver's platform then visualizes the entire data package in the form of a real-time "compaction map" and shows the roller operator where has already been sufficiently compacted and where further passes are still required. The WITOS HCQ Navigator process module also allows you to follow the construction site progress worldwide in real time.
