Crews are replacing an old 10,000 pound chilling tank with a 16,000 pound one.
SIOUX CITY, Iowa (KTIV) -
If you were driving through downtown Sioux City, you might have noticed part of 4th Street was blocked off Wednesday morning.
That's because a giant crane was working to take an old chilling unit off the roof of the Ho-Chunk Centre.
The old tank weighs about 10,000 pounds and is being replaced by a unit that's 16,000 pounds. As a precaution, parts of the building were cleared of workers and streets were closed during the operation.
The big tank had been up there since the building first went up more than 30 years ago. Workers say it's a fairly simple procedure, if you've planned ahead.
"Pretty simple procedure. Right equipment, right guys. It goes like clockwork," said Kurt Hansen of The Dunham Company.
