On the west coast of Norway, four Liebherr tower cranes are involved in the construction of the Ytre Steinsund Bridge, a cantilever structure designed to strengthen the link between the coastal areas around Hardbakke. Scheduled for commissioning at the end of 2026, this project is taking place in an environment characterized by sustained winds, rough seas and a restricted working area.
A configuration adapted to Sognefjord conditions
The site is supported by a 132 EC-H tower crane and three 280 EC-H 12 Litronic cranes. These high-top models, with hook heights ranging from 27.5 to 60.3 metres and a maximum working radius of 60 metres, handle steel and concrete structural elements. The cranes operate directly from the shore, or from platforms raised above the fjord.
The Litronic control system integrated into the 280 EC-H allows safe, precise movements, even in rapidly changing weather conditions. This technology supports lifting operations from supply vessels to bridge spans, guaranteeing load stability during transfer.
Foundations designed for stability
To meet the diverse constraints of the site, the cranes rest on several types of foundation. Three of them are installed on transverse bases and reinforced concrete foundations anchored to the ground. The fourth crane is located directly in the fjord, on a steel structure partially cantilevered above the water and fixed to the seabed. This configuration ensures constant stability, essential for precise lifting maneuvers.
A central role in the site's progress
Liebherr cranes are used to position bridge segments and prefabricated elements delivered by sea. Their operational reliability and adaptability mean they can keep up the pace of construction despite the constraints of wind, waves and maritime logistics.
