No. The joint isn’t threaded, it’s a slew ring. Think of it like a wide diameter ball bearing (rod bearing? Pin bearing? Not sure about the English word…) with some extra locking mechanisms to hold the top part in place.
What happened here is most likely a damaged or worn slew ring.
Source: I helped replace the busted slew ring on a ships crane once.

So is it possible to swing infinitely any way? Or is there a limit because of electric cables or something?
Unlimited, other than wear and tear of course. Electricals and hydraulics go via a slip ring.
