2016.11.01 – Elevator Shaft Reline

Fabrication of the top of a 930 ft. elevator shaft reline (92 shells x 14’ – 6’’ dia. x 10 ft. long.)  Starting from the bottom the shells are more heavily constructed and as we get nearer the surface the shell thickness lessens as do the number of external stiffener rings. The average weight per shell thru the first 30 has been about 46,000 lbs.
