Moving lighter but cumbersome equipment

Cool, I think that is a reasonable price for that!

I'm wondering if the adjustment for the aprons is that big nut on each side towards the bottom. It looks that if that is loosened or tightened it would adjust the height of each side of the apron.

We might need a couple of close up pictures and of the apron half swung up....

There is no information or manual in print/ online.
A nut is either side each apron; I think it restrains a heavy coil spring, so must be part of adjustment, sprung or not.
There are milled angle irons bolted to each apron, they have slotted holes. Aprons have tapped holes for 'back gauge', haven't Ouija-ed them around to see how. I do NOT want having to layout runs of identical parts.
Patent drawings indicate hydraulics in similar configuration, things look related but not as expected in patent applications. Sorting out that magic hat, way different than previous work.
