The swings are a bit different from a playground swing in that they include limit stops to prevent people from swinging dangerously high. I expect that people are abusing the swings and bumping hard against the stops. The short distance between the pivot axis and the stop itself creates a large force multiplying effect - perhaps enough to shear the bolt. The limit stops are hard to see as they'd be located up high near the pivot or even inside the light ring. I'd be curious to see if the swings get redesigned with the stop located outside of the light ring, further from the pivot axis, to beef it up. I'm sure the designers would have resisted that option as it would be ugly and create pinch point etc.
I think it's a lot of what you describe - it's what I was thinking and you explained it much better than I could.
