It’s the cross member that the stub axels mount to. It’s not the best picture but it looks like a standard sub assembly to me. There is a piece of box section welded to it at each end which is then "U" bolted to the longitudinal trailer sides.
No markings on the trailer to suggest a manufacturer and as it’s only a yard trailer don't want to spend a fortune.
That's an original Indespension roller coaster, from what I can see. They used to make them like that about 20yrs ago - independent suspension units, mounted to a v cross member. This was prior to them fitting the full beam torsion axles.
To be honest, you'd likely be fine just using a bit of square box, as the hull would likely clear the cross member, due to the swing cradle rollers. If its a bit close, just raise the rollers.
