📋 Tender Overview
In Boheimkirchen has been working diligently in recent weeks. The renewal of the so-called Stossingbach Bridge over the Michelbach was completed after only three months. The object of the construction project was on the one hand the rebuilding of the steel structures of the railway bridge and on the other the installation of new massive carriageway slabs in the subsequent viaduct areas. As part of a three-week single-track barrier the two old steel structures from 1947 were replaced by two new steel structures with a continuous ballast bed which also causes less noise propagation during train journeys on the bridge.Giant crane in actionA challenge was the removal and lifting of the structures. For this purpose a caterpillar crane weight 540 t payload 650 t that was not used on a daily basis was required. Due to its dimensions the crane had to be transported in individual modules and assembled on site. With the crane the structures were then lifted over the overhead line and carefully brought into the intended position. Precision under high time pressure was demanded of all participants.Load tests before commissioningOn September 22 and October 11 the new structures were each subjected to a stress test with an 80-ton Hercules diesel locomotive. The schedule of the construction site could be kept exactly. In November the drainage systems below the bridge are still being built in order to be able to divert the surface water of the bridge then the project is completely finished.
