BKL provides 1,800 tonne-metres for railway bridge.

Munich, 5 May 2026 – For the refurbishment of a historic railway bridge over the river Sieg in western Germany, the Bauunternehmung Albert Weil AG required a crane solution capable of lifting very heavy reinforced concrete parts over long distances. The renowned civil engineering contractor therefore approached the crane specialists of BKL Baukran Logistik GmbH to carry out the lifting operations, and thus complete the extensive main works on the 140-year-old, 168-metre multi-span arch bridge as quickly as possible.

Two heavy-duty cranes save time for relocation.

For this infrastructure project, the team of BKL Frankfurt relied on two real powerhouses from the BKL crane fleet: an 800-tonne-metre crane TLS 800 50T from the BKL System Sáez and an 1,000-tonne-metre crane 21LC1050. The rental experts planned the deployment of the two powerful giants with radii of 70 and 80 metres and positioned the flat-top cranes on opposite banks of the river Sieg with hook heights of around 37 and 38 metres. This setup enabled loads of up to 10 tonnes to be lifted across the construction site without the need for time-consuming repositioning of the cranes during the construction phase. The crane solution featuring BKL’s heavy-duty duo enabled the client to successfully complete the partial renewal of the railway viaduct, as well as the refurbishment of its foundations in the river and the existing vaulted masonry, within the tight timeframe of three months.

BKL is investing in heavy-duty cranes for infrastructure projects.

The two heavy-duty cranes, each with a maximum lifting capacity of 50 tonnes, are part of BKL’s fleet of large cranes available for hire. Since last year, the family-owned company has invested in several top-slewing cranes in the 800 to 1,100 tonne-metre class, thereby offering its customers more than 40 heavy-duty construction cranes ranging from 500 to 1,100 tonne-metres, as well as over 15 heavy-duty mobile cranes with a lifting capacity up to 700 tonnes for upcoming infrastructure projects.
