This is getting somewhat off topic of practical coils, however, it is an
interesting aspect of large coil construction.  You would probably do well
to research how other large structures are built and maintained, Tesla's
tower at Wardenclyffe being only one example.  Technology has advanced
somewhat since those days, too.

Imagine a large cylinder some 20-30 ft in diameter..  Or more accurately, a
framework of structural members, cross braced, etc.  If it can take seismic
and wind loads, it can take the load of a 500 pound scaffold hanging on one
side.  I'd research the curved fiberglass walkways available to make a ring
catwalk.  Rig it with suitable hoist cables and you're done.

Do the calculations and figure it out... you need to tradeoff losses,
mechanical strength, and cost..
