Installation in general

We safely handle even the most unique installation!

The planning process is the key to success

Upon receipt of the tender documents, our staff in the sales, installation and technical departments go into action. In close cooperation, quantities are calculated and technical specifications are generated. Installation methods are analysed, tested as to their feasibility and described down to the last detail.

A host of things have to be carefully considered: Roads and streets that have to be bridged or crossed are often subject to certain requirements, the same applies to watercourses or waterways, rough terrain, existing structures, precipitous working heights or ongoing sporting and other events in stadia and sports grounds.

For the final construction planning, the load-bearing systems are disassembled into their individual components, the construction process is accurately planned, and the production of adjoining building components is predetermined. Together with the planners, the framework conditions necessary for the installation i.e. intermediate stages of installation, connection of the cables to the structure connections, guidance of forces and tensibility are depicted and calculated.

Installation of cables is often carried out in precipitous spots under the most difficult of circumstances.

Installation Calculations

During the individual installation steps various load cases occur (i.e. when lifting the radial cable system of a stadium roof) that are closely examined in our installation calculations. This guarantees that maximum admissible forces are never exceeded during installation. The installation calculations provide geometry and forces for individual construction phases and at the same time serve as parameters for force and geometry measurements carried out by our installation team later on.

On the construction site

With our sophisticated installation equipment we are in a position to apply tension forces in a controlled manner, even if we work with large cable diameters, tension forces can furthermore be accurately recorded at any time. In addition to that, we develop and produce special tools, based on the respective requirements in the installation of load-bearing structures, which – if need be – are examined and approved by the authorities. Using hydraulic systems and cable tension metres we can take force measurements also of already finished load-bearing structures. All forces measured and the final geometry are entered into the structure file.

The hands-on experience that we have acquired covers many areas, from the construction of the most varied types of bridges, via the construction of stadium roofs, the construction of fixed and movable roof segments, cablesupported glass curtain walls or membranes to the construction of purposebuilt structures such as vivariums, open air enclosures for birds and climbing paths. A high degree of prefabrication makes short installation periods possible.

General installation instructions are documented in our “Instructions for the installation“ documentation. The documentation provides an overview of minimum requirements when working with cables. Disregard of the general installation documentation can lead to damage of the cables and the whole load-bearing structure.
