A Liebherr 630 EC-H 40 Litronic tower crane played a central role in executing the lifting operations required for building a 135m-tall pylon for the Kruunuvuori Bridge in Helsinki. On completion it will become Finland’s tallest and longest bridge.
Joint venture consortium TYL Kruunusillat used the crane on-site from winter 2022 until structural work concluded in 2025.
Kruunuvuori Bridge is a 1.2km cable-stayed structure connecting Laajasalo, Korkeasaari, and Kalasatama with Hakaniemi in Helsinki’s city centre.
Commissioned by the City of Helsinki, and designed by Knight Architects and WSP Finland, the bridge features a service life of 200 years and serves exclusively public transport, pedestrians, and cyclists.
TYL Kruunusillat selected the Liebherr 630 EC-H 40 Litronic due to its existing availability in the company’s fleet.
The crane executed the lifting and installation tasks needed for forming the reinforced concrete pylon, including formwork, reinforcement cages, and concrete delivery equipment.
Its lifting capacity of 40,000kg and maximum jib radius of 80m enabled it to service all stages of the pylon construction.
The Liebherr Tower Crane Solutions (TCS) team participated from early planning, designing the tower configuration for the required 135m height and anchor positions.
The site’s location across the open Baltic Sea exposed the operation to wind forces and subarctic winter temperatures, which demanded dependable crane performance at high elevation.
Technical assessments addressed both static and dynamic wind forces on the crane assembly, a necessity because of the pylon’s height and the bridge’s exposed maritime setting.
One of the TCS team members said: “Both the complex guying geometry and the regular adjustments to the guying and hook heights, driven by the progress of the construction works, required a high level of structural engineering expertise.
“By fully utilising the available structural capacity, we were able to apply our know-how to deliver a safe and efficient solution.”
Bridge construction continued through Nordic winters. Liebherr said this verified the mechanical durability and operational control of the crane’s Litronic system in low temperatures.
The collaborative technical configuration process aimed to ensure safe and consistent operations throughout the build.
When it opens in late 2026, Kruunuvuori Bridge will provide a sustainable transport connection for over 20,000 new residents in Laajasalo.
