I want to build a 38' folding hangar door and I am looking for plans or someone with practical experiance who could give me some tips. 

I have noticed that there are at least two types of lift systems: winch/cable and hydraulic. Where do they get those long hydraulic rams and what size are they? Or is there a better way?

Have you ever heard of a Ladd door?  Bob Ladd was an early EAAer who designed a simple, low-cost, DIY hangar door.  Plans and parts kits are available:

There are a lot of hangars with Ladd doors around the Milwaukee area (the craddle of EAA) and they all seem to be holding up well.  Give it a try.

Thanks Jeff and no, I had not seen this door, but I would prefer to build a steel framed door. Tubing is inexpensive in my area and welding is easy and fast.

I built a 37ft bi-fold door out of 2x2 tubing.  Welded it up on a 40ft flat semi trailer turning it with a loader tractor.  Hung the door with the same loader tractor.  Used heavy pin hinges in the fold, and used strap hinges with 1" pins on the top.  Since I have no electricity at the hangar, used tractor weights to counter balance and raise it up and down by hand.  Simple lockover latches secure the door.  Tractor weights weren't my idea....saw several doors like that at Salem, IN.  Works fine and has for 15 years.

 Mel,

 Here is a page from my website that describes a strong, lightweight set of easily made doors that require no weights, motors, or electricity to open or close.

 

Here's the URL:

Sorry, I don;t have plans, but the webpage should give enough information to adapt the idea to your situation.

Thanks everyone, I will check all of these out. Keeping mice and rats out is a worthy goal so we need some great sealing doors and the bi-fold doors certainly look like they could do that. /mel

I have big Deere with a loader and it's true you can build just about anything with it.  Do you have any photos you could share?

Thanks! /mel

This is what I came up with for a door design. We are going to start on the two sections in a couple of weeks and hang them from an 8"x5" "H" beam that will go in after we open the end of the shop up. We will lift it with 2 - 110 volt winches.

Still looking for these big hinges - would like 3/4" or 1" pins.
