Bridge erection with mobile crane Liebherr LTM 1300-6.2
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 300-tonne crane provides strong lifting capacities and was perfectly suited for this application,” said Michael Schmitz, Technical Director at HKV. The LTM 1300-6.2 was delivered to HKV in April this year and is equipped with Liebherr‘s innovative VarioBase® support system which provides increased safety and higher lifting capacities.
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.
