Hi All, The copper "ladders" on one of our Cu plating tanks (500 gal.) are due for a rebuild. Currently, each "ladder" consists of a rectangular Cu frame with cross bars bolted/ welded in place (the anodes & panels hang from these crossbars). Current is supplied from the rectifier to each crossbar via a separate cable. Our equipment maintenance guy suggested that we can remove the rectangular frame (cost consideration) without reducing plating consistency/ efficiency. He would attach U shaped blocks to the tank rim to support each crossbar. (I think the frames are a carryover from the old days when we used fewer cables). Seems to me that this should work fine. What do you think?
