Liebherr has highlighted the role of its 630 EC-H 40 Litronic tower crane in the construction of the Kruunuvuori Bridge, which will become Finland’s longest and tallest bridge when it opens later this year.
The crane was deployed by TYL Kruunusillat between winter 2022 and 2025 to carry out all lifting operations associated with the bridge’s central 135-metre-high diamond-shaped pylon, one of the most complex elements of the project.
With a maximum lifting capacity of 40 tonnes and a maximum jib radius of 80 metres, the 630 EC-H 40 Litronic was used to position formwork sections, reinforcement cages, concrete delivery equipment and structural components throughout the construction process.
The crane’s configuration required extensive engineering support from Liebherr Tower Crane Solutions, which was involved from an early stage to calculate tower configurations and anchor tie-in positions suitable for the unusual height requirements of the project.
The bridge site presented significant challenges, including exposure to strong Baltic Sea winds, sub-zero winter temperatures and the complexities associated with operating a tower crane at extreme heights. According to Liebherr, the combination of robust crane design and the reliability of the Litronic control system ensured safe and efficient operations throughout multiple Nordic winters.
Commissioned by the City of Helsinki and designed by WSP Finland and Knight Architects, the cable-stayed bridge spans approximately 1.2 kilometres across Kruunuvuorenselkä Bay and has been designed with a service life of 200 years.
When it opens to tram traffic in late 2026, the Kruunuvuori Bridge will become one of the world’s longest bridges dedicated exclusively to public transport, cyclists and pedestrians.
