HAMM’s WITOS HCQ Tracks Compaction

At CONEXPO-CON/AGG 2020, HAMM, Antioch, Tennessee, presented WITOS HCQ—a system for live tracking of rollers. With WITOS HCQ, HAMM has introduced a new addition to its HCQ Navigator system. With a panel PC in the cabin, HCQ Navigator provides a live indication to roller operators of the points that were already sufficiently compacted or where further compaction is necessary. This prevents over- and under-compaction while helping to optimize the number of passes.

HCQ Navigator saves all of the data that is recorded during the compaction process. The new WITOS HCQ module makes it possible to monitor the compaction progress – in real time and even from a remote location. Simple browser-based operation is used since WITOS HCQ was designed as a web application. During the compaction process, data is transmitted directly from the rollers to the WITOS portal of the WIRTGEN GROUP via cellular radio. Users can then access the data in real time. Regulatory authorities or consultants can also be involved in monitoring the compaction progress via a suitable interface. This ensures the confidentiality and integrity of the data since access permissions can be separately granted to different persons for each subproject.

After completion of the work, WITOS HCQ has other advantages since automatic storage of the data on the WITOS portal greatly simplifies the back-up process. There, the project data is available for subsequent analysis and documentation purposes. The data format meets all of the “VETA” requirements.
