| I've seen a few turn table ideas based on the large ring gear but they only
seem to be able to handle large compression loads. I'm looking for a solution
that can also handle tensile loads, at least on one side. For example in a crane
with imbalance between load and counter load, one side of the turn table gets
pulled apart from each other. A smaller turntable in the center that holds the
top part of the larger turn table is not strong enough to prevent this from happening.
Any ideas how to counter this?

Look at
it’s on a big turntable
I think it was pretty stable (though the whole build was not well balanced).
Or you may bracket the turntable with wheels: [=] where = is the turntable,
and the brackets have their bottom fixed to the base of the turntable and their
top have wheels that go over the top of the turntable, so they hold the top but
without (much) friction.
Of course, applicability depends on the size of the turntable you want to build
