Kö-Bogen Tunnel

Düsseldorf | Germany

The construction project

As part of the Kö-Bogen Tunnel project in Düsseldorf, Hodapp GmbH & Co. KG installed a single-leaf fire protection swing gate specially adapted to the local conditions.
The gate serves to safely close a tunnel section in the event of an incident and, due to its high-quality design and robust safety technology, is an important component of the technical tunnel equipment.
After the positive experience with this gate, three more identical gates were installed.
