Conductix-Wampfler in cooperation with its South Australian distributor, Noremak Industries has supplied a large pre-assembled festoon system for Onesteel Whyalla.
The objective of the project was to upgrade the festoon system on the export shed distribution tripper system to achieve reliable operation. The process of installing the replacement system in this operating environment was a major challenge, which has now been successfully accomplished with much of the work being done off-site.
The system supplied was a Conductix-Wampfler heavy duty square track festoon system (running on a 100mm square track) with a travel length of 270 metres in addition to 42 trolleys as well as supporting power and control cables to facilitate the reliable 24/7 operation of the Onesteel Whyalla export shed tripper.
The festoon system is fully automatic so reliability is of utmost importance.
The festoon system was pre-assembled and delivered in a sacrificial frame including a lifting beam. Pre-assembly of the system was performed by Conductix-Wampfler at its Melbourne factory with tow ropes, cable cleats and all system elements fitted under ideal conditions.
Pre-assembly of such festoon systems is quite common but this project included the added challenge of the 18m length.
In order to facilitate transport, the assembly frame was designed in an articulated manner with a hinge mid-span so that the assembly could be completed and the system quality checked in its full 18m spread. The system was hinged into a 9m long frame for transport.
Once on the site, the transport frame was again opened up to its full 18m length with local support from Noremak Industries.
Installation of the system was performed by Onesteel essentially by raising the complete lifting beam with festoon fitted, holding it adjacent to the pre-installed track and rolling the trolleys progressively from the lifting beam onto the permanent track.
To add to this challenge, the installation was performed through a temporary opening in the building wall approximately 27 metres above ground level.
Conductix-Wampfler is an established supplier of heavy duty festoons to the mining and manufacturing industries. In Australia, the company operates from facilities in Melbourne, Sydney, Brisbane and Perth as well as through distributors such as Noremak Industries in South Australia.
