Theatrical rigging system for installation in event hall

Theatrical rigging system using e-chain and chainflex cables

Safely installing and moving state-of-the-art equipment in a modern event hall: This was the task with which Alfa System Sas, a stage technology specialist, was entrusted. To ensure that the complex, specific cabling can be safely moved over long travels up to the hall ceiling, a plastic energy chain that is wound and unwound on an e-spool is used. For cables, the customer uses our chainflex cable range for moving applications.

Problem

The GES2 auditorium is a prestigious venue, for which an elaborate multimedia installation including a special cable winch construction was planned.fa The Italian specialist for stage and theatre technology, Alfa System Sas, was entrusted with the task of ensuring the complete installation and reliable moving of spotlights, projectors, loudspeakers and other stage elements.
The idea: several winches were to be arranged side by side in batteries, each moving a rod onto which the expensive equipment could be hooked. In the case of lights, projectors and loudspeakers, the power and control cables to these devices must also be guided safely.
As the GES2 auditorium is part of a very prestigious complex for hosting top-class events, the multimedia systems installed are all of excellent quality.
In addition to stringent requirements for cleaning the installation, there were therefore also strict regulations regarding the types of cables to be used and their performance. In addition, the cabling of the devices entailed high specifications with few possibilities for compromise. High-resolution cameras, speakers, microphones, light projectors and other devices all had their own cable requirements.

Solution

The numerous cables, such as fiber optic and signal cables, are now guided in their respective specifications in several e-spool systems. An e-spool is an energy chain including a drum that can be rolled up and unrolled safely and, in a space,-saving manner.
The e-spool was used instead of a traditional cable drum because the latter would have required the construction of special cables that would not have been tested in use and whose performance would have been unknown. The e-spool can handle the broad cable mix in full compliance with the project requirements and in conjunction with the multimedia technology.
The e-spool system was installed near the hoisting winches in a machine room. From here, the energy chain is guided to the equipment with a specially designed guide and roller path.
Alfa System also uses our chainflex product portfolio for moving applications for the cables themselves. The wide range of products enabled the customer to find all the required cable specifications in one place. We also offer a 4-year guarantee on all cables in the portfolio.
