Help identifying this??

Bought this at an antique shop last weekend. I was it was a lineman seat but I think it’s too heavy. Thought maybe it’s train rung seat or military vehicle seat. Thank you for the help.

Does it fit on a ladder?

Looks like a platform for a ladder.

some kind of table for scaffolding?
Locking hooks to secure it makes me think used high.

didn't think about a scaffolding but the sturdiness of it makes it possible. Thank you
