Portal cutting system bridges civil
engineering
ESAB's Suprarex cutting machine is used in the fabrication of a giant steel bridge known as the Berliner Brucke by a German civil engineering fabricator.
A major German civil engineering fabricator has been reaping the benefits of ESAB's Suprarex cutting machine in the fabrication of a giant steel bridge known as the Berliner Brucke The 73 metre high and 650 ton all-steel construction has two base piers which meet at a height of 35 metres and form an A-shaped gate above the road

Welding and cutting machines in an easy package
The recently extended ESAB Origo range offers affordable welding and cutting machines for customers who require reliability in an easy to use package.
The base piers are topped by the pylon peak where the cables are anchored.
The openings, through which the diagonal cables were suspended, had to be ultra-precisely cut into the steel plates.
The cutting task was very complex because elipse-shaped inner contours had to be cut into complicated steel plates.
For these highly demanding cutting tasks, the Suprarex portal cutting system was adapted to the company's specific requirements.
Not only did they need a high-performance plant for cutting material of a thickness of up to 150mm, but also an extremely flexible oxy-fuel cutting unit, for the complex elipse cuts.
The Suprarex features a continuously turning three-burner unit with which any geometries could be realised with double-bevel grooves, Y-as well as V-grooves by oxy-acetylene cutting.
The other features of the portal cutting machine included a single oxy-acetylene cutting torch as well as plasma marking.
During the planning of the production process, ESAB's Columbus programming system proved to be a very sophisticated and flexible tool.
After a brief introduction, the customer was able to program the cutting processes required.
The program, which was developed on a PC, was simply downloaded from the company network and processed by ESAB at the cutting machine via its VISION controller.
It was even possible to integrate easily complex geometries such as the elipse cuts and bezel cuts in the program sequence.
High-precision work was required for the assembly of the peak of the pylon from individual components.
Both side elements of the pylon were placed on the assembly bed in the workshop to insert the tubes, which were already equipped with flange and ribs, through the elipses and then welded. Request a free brochure from ESAB ...
