One of the outfits that sew up nylon chokers makes a sling for a single bottle, it meets OHSA and it's spendy. A choker that is long enough to allow 3 bites on the bottle, One close to the bottom, the second about 1/2 way up and the third about 18" from the top will work if someone can land the bottle and set it uprite and make sure it is stable.
I'm not able to post pics but if you have a fax# I could send a drawing of
a bottle carrage for use with a crane.

Not that this is always a virtue.
Fleas are interested in dogs." -P.J.O'Rourke
