I can't see from your photos how you're stopping the main structure lifting off
the base.
Correct me if I'm wrong, but crane turntables hold the superstructure down so
the load moment is transferred to the crawler base. I've seen photos of cranes
tipping and they don't fall off the turntable, they take the base with them.
I've had a couple of (incomplete) goes at a crawler, and I've 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 can't detach from the base.
Great looking model so far though.
Regards
