Kaiser Aluminum Crane Runway Rehabilitation—Trentwood, WA

After completing bridge crane runway surveys in two buildings at this aluminum rolling mill, Dix was asked to bring the soaking pit runway back into compliance with CMAA standards. The work included aligning the runway girders, tie back and bolt replacements, weld repairs and supplying and installing 750 adjustable rail clips. Dix also supplied and installed three replacement girders and 2,080 feet of continuously welded 85 lb ASCE crane rail. The work was performed while the plant was operating, requiring close coordination between Dix work and the owner's operations. After the first operational test, the runway was accepted without further corrections. In the words of Kaiser maintenance personnel, "You can't even hear the crane going down the runway".
