Robust energy chain system for oversized outdoor screen

Robust energy chain system for oversized outdoor screen
Located at the Victory Plaza in Dallas, Texas, just outside the American Airlines Centre, You'll find an oversized moving-screen LCD display, visible to everyone passing by. The Belgian Barco Group, a leading designer and developer of solutions for large-screen visualization has developed the display with eight 26ft screens. Robust Igus E4/4 Energy Chains of the series 4040 with Chainflex fibre-optic cables, motor and control cables guarantees safe energy and data supply. 

The maintenance-free plastic Energy Chain System and its cables are exposed to harsh environmental elements: extreme heat, sun, rain and snow with an operating schedule of the LCD screens for up to 18 hours per day, 360 days per year. "The Igus team rose to the occasion to help us find a perfect solution," said Lawrence Allen, senior engineer of Barco. The cables of a competitor had failed and the cables were not rated for temperatures dipping below 5degC, which then began to corkscrew and compromise the performance of the system. Lawrence Allen continues, "That could have been a potential disaster for our customer."

Eight corrosion-resistant E4/4 Energy Chain Systems, one for each LCD display, have been installed for one year now. The E4/4 Energy Chain Systems of the series 4040 are used worldwide in long travels and also where high and unsupported filling loads need to be laterally guided. A form fitted back stop and a second solid bolt provides optimal interlinking of the chain links and lateral stability. Pressure forces and torsion regidity of the energy chain are generally increased and also the resistance against wet and rough environmental conditions.

The chain links which consist of four parts can be opened from both sides and is available in four inner heights (32 to 80 mm) with an outer width of up to (600 mm). Due to the large modular kit of the E4 system, the E4/4 series can be configured for numerous applications and cable fillings. In addition, there are variable interior divisions, extension frames for large hoses, elements for variable connections to the machine, a aluminum trough system for long and very long travels.
