The LTM 1750-9.1 and LTM 1500-8.1 positioned the 50m steel girders weighing up to 82t each on the bridge pillars at the autobahn building site. The crane professionals from MSG and the bridge builders from Max Bögl were available for exactly two nights to complete the work. Several of the six lanes of the autobahn had to be closed to erect the cranes on and next to the A5. The autobahn had to be closed in full during the night so that the work could be completed.
The massive composite prefabricated parts were delivered to a parallel bridge using heavy load transport vehicles. With a range of more than 30m the cranes hoisted and then positioned the steel girders in tandem. The two Liebherr cranes had to be able to handle maximum load cases of 44t and 41t. Seven of the steel composite elements were installed during each of the two nights.
