Maybe you don’t recognise it immediately as an elevator, but it is.
Only for transporting kegs one level up or down.
We used it ourselves also. Standing next to the kegs. It saved some time.
Sometimes I’m using it when during the tour there is an old lady who can’t descend & climb the steep stairs we have.
But it is forbidden!
It says on the sign too: Forbidden for people, Max lifting capacity 1000 kg.
So just 1 old lady. Not more than that. Maybe her stick. Not more.
