Liebherr Defies Wind and Waves

Four Liebherr EC-H cranes are in operation on a demanding maritime infrastructure project. On the west coast of Norway, four Liebherr tower cranes are contributing to the construction of the Ytre Steinsund Bridge, a cantilever structure designed to strengthen the connection between coastal areas around Hardbakke. Scheduled for commissioning at the end of 2026, the project takes place in an environment characterized by strong winds, rough seas, and limited workspace.

The site relies on one 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 meters and a maximum outreach of 60 meters, handle steel and concrete structural elements. The cranes operate directly from the shore or from elevated platforms above the fjord. The integrated Litronic control system in the 280 EC-H ensures precise and safe movements, even under rapidly changing weather conditions. This technology supports lifting operations from supply vessels to the bridge spans, guaranteeing load stability during transfers.

To accommodate the site’s diverse constraints, the cranes rest on different types of foundations. Three are installed on transverse bases with reinforced concrete footings anchored to the ground. The fourth crane is positioned directly in the fjord on a partially cantilevered steel structure above the water, anchored to the seabed. This configuration ensures constant stability, critical for precise lifting maneuvers.

The Liebherr cranes handle the positioning of bridge segments and prefabricated elements delivered by sea. Their reliability, operational performance, and adaptability allow the construction schedule to stay on track despite challenges posed by wind, waves, and maritime logistics. With a combination of robust design, precise control systems, and tailored installation solutions, the EC-H cranes effectively support the construction of the Ytre Steinsund Bridge, a key project for regional connectivity along the Sognefjord.
