I.D. Type of Pin with Ring & Slot + Ridge + Empty Slot

I could not find a match for these in any generic online catalog of pins so I am thinking they may be specific to a particular vehicle or piece of machinery. Is there a specific name that applies to this type of pin?

The tops are flat. The bottoms have a divot in them.

They look like hydraulic porta power extension couplers with the ring, not on both ends as it should be for that purpose

That's weird...the pic shows up on my tablet, but not the big computer. And yeah, it is huge...no help on the pins, as Gary said, maybe porta-power or maybe scaffolding? Some application where quick breakdown is needed...
