Trade fair construction company Kurt H√ºttinger GmbH was
engaged to create a kinetic sculpture that would hang at a height of four
metres above a water feature in the foyer of a Taiwanese hotel. Consisting of 168
individually positioned metal spheres, the sculpture was a delicate work of art
backed by a good deal of technology.
There were several challenges for Kurt H√ºttinger GmbH
during the execution of the sculpture. The system needed to be easily
accessible for maintenance, even though it had to be installed within a
metre-high inaccessible false ceiling four metres above the ground. Installation
of the work of art had to be completed quickly before the official opening. A
cable lift, which can permanently accommodate the technical unit, had already
been installed in the structural shell of the building.
A highly complex yet reliable and discreet cable
management system for control, audio and energy cables was required to make the
spheres move in time with music.
The igus e-spool with compact twisterband ensured
reliable cable feed in a confined space even under the most difficult
conditions. It also met the requirements for quick installation, easy maintenance
and simple operation.
e-spool: the practical cable drum system
“For our cable problem, we found the perfect
solution in the form of the igus e-spool,” explains Stephan Hessberger,
head of technical design at Kurt H√ºttinger GmbH.
The energy chain is suitable for supplying energy in a
very restricted space and is routed over a roller. Integrated retraction
springs ensure the correct length and tension of the cable management system at
all times. In the home position, the e-chain is completely rolled up to save
space. The compact twisterband connects the roller to the shaft end block,
which serves as an interface to the fixed cables. The cable reel was filled
with cables, mounted on the unit and tested ahead of the installation.
“This was the only way to ensure that a work of
art, made and assembled in Germany, could be flown half way around the world
and installed quickly,” says Stephan Hessberger enthusiastically.
For installation, the complete unit, including the e-spool,
was placed on supporting wheels, attached and lifted by hand. The loose end of
the e-spool was mounted onto the hidden ceiling and connected up. It was then
possible to continue the installation work and set the work of art in motion.
