Barnhart was hired to remove and replace a 20,000-pound scrubber at a chemical plant in Arizona. It was 34’-8” tall and 6’-6” diameter and inside of a 70’ tall structure. The team used a Liebherr LTM 1220 crane and 75-ton temporary trunnions to lift the scrubber vertically out of the structure.
The scrubber needed to be tailed from vertical to horizontal for hauling. The existing scrubber’s head lugs were unsuitable due to corrosion and other factors. No tail lug was present.
To tail the scrubber, shackles were connected to two anchor bolt chairs and a second crane assisted in bringing the vessel into a horizontal position. It was then set to cribbing prior to being loaded onto a trailer.
