Networked hybrid rollers at Hagedorn.

This innovative tandem roller combines a new hydraulic energy recovery system with the diesel engine and ASPHALT MANAGER to create a highly efficient drive unit. The BW 174 AP pivot-steered hybrid roller reduces diesel consumption by up to two litres per hour and CO2 emissions by around a quarter. The combination of particulate filter, oxidation catalyst and a cooled exhaust gas recirculation system enables the 10 t machine to run even without additives such as AdBlue. This has a positive effect on both operating costs and the environment.

For managing director Roman Kohler, the BOMAG machines with their smart measuring technology and surface covering compaction control are also an important prerequisite for the digitisation of construction sites. “BOMAP is the new mobile solution that allows you to document compaction results on site in real time. We are the first Swiss construction company to use the BOMAP Connect add-on. The two new hybrid rollers are networked with the other rollers via GPS. This generates a complete compaction map of the construction site. Digitisation is ground-breaking for medium and large asphalt construction sites, because the software also ensures detailed logging of the entire compaction process. That’s why we have already ordered two additional hybrid rollers with BOMAP Connect from Probst Maveg for the next surfacing season,” explains Kohler.
