If the top channel section is what I think it is, it will contain sets of 4 wheel trolleys, which roll along the inside of the channel. The metalwork is quite expensive, for 18ft of it I was quoted 250 pounds, but it does last a long time.
If you put the door in the most stiff position, there may be lock-nut adjustments that can be made to ease the binding. Hopefully that will not make the door too loose at the other end of its travel.
Best of luck..
Thanks for the reply scifi. It is a nice hangar and I should add that the photo was taken some time ago. These days, any attempt to swing a cat in there would result in feline fatalities. I.e. its full!
What you suggest about four wheel dollies sounds likely. Its how to access them to make adjustments that's not obvious.
Crash one The channel in which the top of the door runs is part of the structure of the hangar, so raising it would not be a simple matter.
