The motorway section of the A3 between Cologne-Mülheim and Leverkusen is being expanded to eight lanes. However, since the old motorway bridges are not long enough for the expansion, new bridges are needed. As a temporary solution during the construction work, a Liebherr LTM 1300-6.2 mobile crane was used by the company HKV Schmitz + Partner to erect a makeshift bridge overnight.

The entire section of the motorway was closed during construction of the temporary bridge, which meant the work had to be completed within a narrow time window. HKV Schmitz + Partner GmbH chose to deploy its Liebherr LTM 1300-6.2 to ensure a smooth and fast operation.

The LTM 1300-6.2 was delivered to HKV in April this year and is equipped with Liebherr's innovative VarioBase® supporting system which provides increased safety and higher load capacities.

Fitted with the total ballast of 96 tonnes, Liebherr's 300-tonner soon got to work on the motorway construction site. The temporary bridge was delivered in four parts by semi low-loaders; the heaviest single piece weighed in at 41 tonnes and the length of the longest section was 24 metres. The LTM 1300-6.2 unloaded the sections from the low-loaders before placing them onto prepared foundations, where they were erected to form the temporary bridge.

At the same time, HKV used an LTM 1400-7.1 to install another makeshift bridge over an adjacent section of motorway.
