I always think it's funny when people use large planes as a reference for heavy weights, since they're designed to be as light as possible for the volume.

Probably best to compare Arecibo to a suspension bridge instead
Golden Gate bridge is 887 000 tons: https://edition.cnn.com/2013/11/01/us/golden-gate-bridge-fas...

So around 1000 times as heavy.

That sounds like the weight of the whole thing, not just the suspended part.
I think the Golden Gate Bridge is massively overengineered (although nobody really knows) because materials engineering wasn’t super advanced back then.
I don't think the instrument platform was exactly designed to be heavy!
