AusGroup (now part of Altrad) was commissioned to fabricate, machine, surface treat, assemble and install the two CV401 & CV402 stacker boom replacements. Each were fully dressed with idlers, guards, grating and handrail and both were assembled to the stringent requirements of the client.


Salt processing has its complexities with constant corrosion, so emphasis was placed on specialist surface treatment on the booms and the isolation of stainless steel from carbons.

The two CV401 and CV402 Stacker Booms were transported from AusGroup Kwinana Operations to site in Dampier ready for the team to install on site.
