![]() A total of 525 tonnes of MSH sections, made in the V & M TUBES production plants at the Düsseldorf-Rath, Mülheim, Aulnoye and St. The superstructure rests on seven pairs of round, reinforced concrete piers built on shallow foundations. The bearing support of the framework on the piers is provided by V-shaped struts made of MSH sections, which are connected to the superstructure framework by cast steel joints. The reinforced carriageway deck, which is longitudinally prestressed, ranges in thickness from 23 centimetres at the cantilever arm end to 106 centimetres over the diagonals. Both top chords consist of Isections with welded stud shear connectors and are concreted into the carriageway as composite girders. The bottom chord of a 4.40 metre high three-chord main girder consists of a structural hollow steel section with a diameter of 610 millimetres, while the diagonals, which are also made of MSH sections, have a cross section of 299 millimetres. Two separate composite framework superstructures define the four-lane viaduct over its whole length. The height of the structure is 5.0 metres and the total width is 28.5 metres. The bridge consists of a total of eight spans with widths 55.35 m, 5 x 61.5 m, 49.2 m and 36.9 m, and rests on parallel tubular lattices, 14 metres above pairs of slim reinforced concrete columns. After consideration of the technical and architectural aspects, the variant presented by structural design planner Prof. The increased sensitivity of clients, local residents and countryside campaigners were decisive factors influencing the decision in favour of the slim and elegant, and above all light and transparent, steel composite bridge. In Switzerland, as on the A 73 federal autobahn to the north of Schleusingen, in Thuringia, an especially harmonious solution was sought. Composite steel bridges, whose carriageway deck is supported on a filigree steel tube truss structure and slim piers, which carry it overvalleys and bridges, are especially preferable to normal prestressed concrete bridges when a “soft” compromise is sought between protection of the landscape on the one hand and hard transport necessities on the other. Usually it is a question of the location and the natural surroundings. The result gives reason to hope – and not simply from an aesthetic point of view – that this may mark the start of a trend towards high-quality bridges with visible structural hollow steel sections. Kilian viaduct at kilometre 14.2 of the A 73 is one of the few autobahn viaducts to be constructed as a composite steel tube truss structure. 16”, which refers to the upgrade of the A 73 federal autobahn in Thuringia, is one of the most exceptional bridges in the German landscape. Kilian viaduct: Superior lightness Behind the bureaucratic-sounding title “Verkehrsprojekt deutsche Einheit Nr.

Market driven right from beginning and strictly focused on lifting and transport of goods, CargoLifter has broadened -up its product range. This new entity owns the patents of former CargoLifter AG and has been continuously creating additional expertise. ![]() ![]() Hit by the downturn of the aviation industry after 9/11, CargoLifter AG had to stop activities during the financial crisis in 2002.Īfter the insolvency of CargoLifter AG, a core team founded CL CargoLifter GmbH & Co. Faced with significant challenges to transport their heavy and large components to the construction site, a group of global players was urgently looking for an innovative transport solution capable of lifting more than 100 tons and oversized units up to 50 m in length.Įstablished in 1996, CargoLifter AG managed to build the world's largest hangar, design and operate the world's largest balloon and start the production of the largest airship ever. The CargoLifter project was initiated by industrial partners in 1994.
