TOWER CRANES Ӏ SITE SHOWCASE
CHALLENGING CONDITIONS Four Liebherr EC-H series tower cranes are building a bridge between islands in Norway.
In western Norway the Ytre Steinsund Bridge is currently under construction. The project is being carried out by construction company Skanska which secured the contract in June 2023. Once completed, by the end of 2026, the cantilever bridge will replace the ferry connection between the islands of Ytre Sula and Sula providing a fixed link to the mainland near Hardbakke. For the project four Liebherr EC-H series tower cranes are being used: three
Liebherr 280 EC-H 12 Litronic cranes, with hook heights of up to 60.3 metres, and one 132 EC-H, with a hook height of 27.5 metres. The high-top cranes have a working radius of up to 60 metres and are lifting steel and concrete components which are being delivered by boat to below the bridge. According to Liebherr the intelligent
Litronic control system of the 280 EC-H cranes ensures smooth and safe
movements, even in changing wind conditions. The cranes are mounted on various
foundation types for optimal anchoring and maximum stability. Three of the four cranes are installed on cross bases as well as on solid concrete foundations with anchoring. The other crane is positioned directly in the water on a specially designed steel frame, which is partially cantilevered over the water and anchored to the seabed.
