Perhaps contact a garage door repair place.? To help lift, they might be able to rig up one of the of those spring arrangements like are used on sectional rollup doors.? But the bulk of the long parallel spring would encroach on the door opening some.? At a minimum, they might be able to give you an idea or two.? It might even be the sort of thing they have seen before.? But even if not, this sort of thing is sort of in their "wheelhouse." I
Another thought.? I don't know how the weight in the wall cavity is arranged.? But it might be possible to affix lever arms to the door that would protrude into the space below and affix heavy counterweights.? It doesn't look like there is much room between the hinge point and the wall so those lever arms (which would probably have to be bent creatively to get around what looks like a beam along the hinge edge of the door) would probably have to be pretty short and the weights heavy.? And with the door open, they arms and weight would be straight down into the room area below.? With the door closed, up near the ceiling of the room below.
If you could move the hinging of the door to the other side, maybe there is more room but there seems to be a wall there, too.? But perhaps it could have a couple of openings made in it to clear levers and weights.? Or maybe the wall with the REA sign can have openings made.? I imagine the wall on at least one side of the stairs has space behind it..

Over the past 20-30 years that I've "been work'in
on the railroad--all the live long day" and basically having a
blast in creating the monster.?? I'm starting to have regrets
over 2 things other than; too small of a room and no
water/bathroom (both beyond my control financially)!?
My isle became a bit cramped due to not planning
for a couple inches for view-block/background+wood trim and my
slightly increased waistline!? The other thing is my
floor-door!? That has become increasingly an issue.? I've
attached a couple of photos.? I wanted to avoid an outside
entrance/stairway, I also wanted to have a clear view of most of
the layout so I wanted to avoid a walled entrance.? So I
surprised the city permitting people, the member who helped with
the room plans not to mention most of my visitors too.? I
laminated two sheets of plywood to make it strong enough to
support at least a couple of guys standing on it, but still open
wide enough to accept a 4x8 sheet of material as it was used for
many photo sets for the NASG, SHS and several other clients.?
To help in raising the door, I used part of a
steel plate cut and welded to make a 60+- lbs counterweight that
I put in the wall cavity. It was never a body building exercise
but over the years it's become more so!?
So I'm looking for a helping hand as I age--any
suggestions?? I've got more photos.? Off hand I've thought about
garage door openers, automotive rear hatch struts and ... (out
of ideas here!)?
