I need to hang a section of tubing to a ceiling for use with a light weight chain hoist.
The tubing will be 7 feet long and mounted at each end. I can't have a center mount support on the tubing because the hoist will need to be slid over the tubing to reposition for another lift.
This will be to lift a light load of no more then 180 pounds and no load will ever be made anywhere except at each end where the mounts are, never in the middle.
I'll use the hoist only to lift a MAXIMUM of 180 pounds on the ends. The hoist will be slid over the tubing unloaded to reposition at the other end before lifting anything.
I'd like to use heavy wall aluminum tubing due to rusting issues.
Question is, what is the recommended size of tubing to prevent bending of the tube?
I can get 1 inch, 1 1/4 inch, and 1 1/2 inch T6061 T6 tubing with wall thickness of 0.25".
What's my best choice?
