Client: Infrabuild & Liberty Primary Steel South Australia

Overview of Job:

Cassaform was engaged to develop and design a system to support and suspend the 150 tonne Reclaimer Truss Beam at the Whyalla Coal Blending Plant in South Australia.

Originally designed in the US and built in the 1967 the Reclaimer Machine required maintenance and refurbishment.  The Northern and Southern end support frames of the Truss along with the roller system needed to be replaced.  Cassaform were engaged from the initial conceptual design phase right through to the final design and installation phase.

Supported on a grillage of spreader beams on the ground to distribute the load and minimise movement, Cassaform designed an intricate support structure on either end of the Reclaimer Truss.  Each support consisted of a frame of 4 x 100t props on either side of the triangular truss and connected by a series of horizontal and diagonal bracing for complete stability.  A structural steel frame was designed and installed on top the propping system to equally distribute the load back to each vertical support during the lifting process.  Two 100 tonne Hydraulic jacks were then installed on the steel frame, one on either side of the triangular truss. The top cord of the triangular truss was stabilised back to the main supports and the jack lifting synchronised to ensure a perfectly vertical lift of Reclaimer Beam.
