If I read correctly the problem is that the springs don't work. I
understand that to mean the the door does not go up or stay up.
The problem is as I read it is that the springs are not strong enough to
lift the door. With regular door door the springs do not hold that much
weight since the door is horizontal on the tracks. In your new setup the
spring must hold a bunch more weight.
My solution would be either counter weights, sort of like a sash weight or a
heavier spring. Get the physicist to do the math on what type of spring you
will need.
