OREANDA-NEWS. August 28, 2014. This summer sees ArcelorMittal and CFL cargo repeating the feat achieved at the beginning of last year. 14 more jumbo beams were transported by CFL cargo from ArcelorMittal Differdange to Dresden for use in the construction of a railway bridge by German rail company Deutsche Bahn.

Oversize beams...
The beams, from the Grey mill in Differdange, are exceptional in terms of their size: each one is 60.6 metres long. To produce them, two beams measuring 37 metres and 23 metres in length were welded together at ArcelorMittal’s finishing centre for beams and sheet piles (centre de parachevement poutrelles et palplanches, C3P) in Differdange.

In compliance with strict quality standards imposed by Deutsche Bahn, the beams underwent numerous inspections, with particular attention being paid to the welds, which were examined with ultrasound and X-rays to detect any defects. “These beams bear testimony to our expertise and our ability to rise to our clients’ challenges,” said Frederic Weissenburger, production engineer at the C3P finishing centre.

...need an oversize transport
In addition to the manufacturing of the beams, the transport by rail of these 14 jumbo beams, which tip the scales at nearly 190 tonnes, is a challenge in itself. CFL cargo’s task consisted of planning the transportation of this exceptional load, while taking into account the scale of the beams. The loading of the wagons, specially designed for transporting these oversize beams, has to be undertaken with extra care to ensure that the train can travel smoothly throughout its journey from Differdange to Dresden. As an ultimate constraint, the delivery must be made “just in time”; in other words, the beams must arrive at the site precisely when they are needed for installation, as it is impossible to store them in the vicinity of the bridge currently under construction.

“This second delivery proves that the success of last year’s operation was no mere coincidence,” Fritz Crelo, CFL cargo’s loading expert and head wagon inspector, points out. “CFL cargo is an European leader in the transport of extra-long beams – an expertise that sets us apart from our competition,” he continues.

And since this operation sets a precedent, ArcelorMittal has requested an entry in the Guinness Book of Records!
