Auto Carriage / Barn Door Opener

Auto Carriage or Barn door opener for my E39 540iA

Just a short post on how I rigged a lift door opener to open barn doors.
Wanted to keep the existing garage doors as they are the original when the house was built in the early 1950's.
Not many places in Australia have barn doors, but it may interest some folk.
Picked up a Securalift unit from Ebay and a few parts laying around in my shed.
Total cost around AU$140.00 including two new aftermarket remotes.

1. Shortened the chain rod by about 600mm as I didn't need the full lifter length.
2. Mounted the controller unit facing the doors.
3. Welded a bracket to fit the shuttle and allow mounting of the two door rods. (these I bought from the hardware shop and cut them down to about 2.2 mtrs long.
4. I then turned down some nylon stock to fit tightly in the ends of the tubes and drilled out holes for the pins on each end.
5. On the doors I used some C section steel with a few holes drilled in to allow adjustments and fine tuning of the opening and closing. Likewise there are 2 holes drilled each side on the bracket that attaches to the shuttle.
6.Made sure the doors are free moving and then set the open and close limits. (Note these work in reverse to the STD. lifter arrangement as the whole thing works in reverse).
7. Set the collision forces close to the minimum amount.
8. There she goes! And with winter approaching- couldn't be happier.

Note: As the system works in reverse the collision force detect will close the doors if it detects force as the doors are opening and so proceed to close doors. If it detects a force when the doors are closing they just stop. While not a problem really and still safe, I are trying to get a schematic to reverse this process.

I recon my old 7 would have fitted with 2" to spare if the garage wasn't full of old printing equipement at the time

Good point. i. Weird thing is I dont even think I have a pix of it. In 14 yrs! Wil do some hunting. I do have pix of my previous rides. A 1967 XR Falcon GT. 1 of only 500 made. THAT I should have kept, but sold it when I got the Giocattolo.
