I cant see from your photos how youre stopping the main structure lifting
off the base.
Correct me if Im wrong, but crane turntables hold the superstructure down so
the load moment is transferred to the crawler base. Ive seen photos of cranes
tipping and they dont fall off the turntable, they take the base with them.

Yes, that is correct.

Ive had a couple of (incomplete) goes at a crawler, and Ive used two
turntables, one inverted, with the centres tied together and to the
superstructure, and the outer rings locked into the base. That way, the
superstructure cant detach from the base.
