Weipa – Amrun Reclaimer BBBWR1001 Slew Bearing Replacement

To facilitate the easier replacement of the drag chain and electrical cabling during the slew bearing

replacement, and to allow for future cable replacements of the working cables in the drag chain, an

upgrade to install intermediate junction boxes at the portal side of the drag chain was required. The inclusion of these junction boxes removes the requirement to rollback cabling to the substation.
