Could you not use two metal box section A frames with block
and tackle? Jon

The plan is to winch it up there, then rachet strap it to the
beam (in addition to the winch), and use the space underneth.
Are you planning on keeping the shell suspended for some time?
Do you intend to walk below the suspended shell?
