THE GOBBINS CLIFF PATH
RESTORATION OF THE 3.2 KM LONG COASTAL PATH
THE PROJECT AND ITS REQUIREMENT
„The Gobbins“ was originally created by an Irish railway engineer called Berkeley Deane Wise in 1902. The path was designed to attract tourists to experience the variety of rocks, birds and animals along the Gobbins cliffs.This was achieved with over 20 footbridges placed along the cliffs. However, in 1954 the path was officially closed and decayed. In 2011-2015 a project was starte to restore and reopen the cliff path.
The aim was also to restore the bridges to make them future-proof and to protect them against environmental influences.
THE SOLUTION
In cooperation with our partner company SDG, Calenberg was able to design and implement its Civalit and Ciparall sliding bearings for the pedestrian bridges. These bearings absorb the movements, loads and rotations caused by the rough weather and the visitors and transfer them to the foundations, as well as the temperaturerelated length changes of the bridge steel structures.They work reliably despite the most adverse weather conditions and salty spray. The installation of our sliding bearings in the bridge structures was realised in mid 2015.
