Hangar door adjustment
Our hangar has sliding doors which run along what appears to be the apex corner of angle iron set into the concrete base. The wheels at the bottom of the doors have a vee groove around their circumference and are encased in the welded steel structure of the door frame, whilst the top of the door, or rather an extension of it, runs in the open side of a steel channel, probably with guide wheels although they can't be seen. The hangar appears to be a commercial design, has no identifying name on it, and is about 25 years old at the most. It was dismantled and moved to our club from another airfield about nine years ago.
The problem is that the one of the doors binds when being opened or shut.
As there is so much potential for expansion and contraction on a large structure (the door aperture is approx 18 metres x 2.5 metres), one would have expected some adjustment to allow for expansion/contraction and settling. From what I can see, any adjustment would have to be on the wheels at the bottom, as there is only about 6 to 12mm clearance between the top of the door and the steel channel top guide.
Have you come across anything similar, and what is the adjustment method?
