Scissors Truss Overhead Door Help Needed

[L+10]

I had my Conestoga pole building built with scissors trusses in one bay to accommodate a four-post car lift so I could store two cars in the bay.

The wall height is 10’ -4” with 8’ high openings.

I’m encountering a problem getting overhead doors installed so that that’ll provide the 12’ clearance needed for the lift. Seems the standard installation doesn’t take advantage of any of the added vertical space provided by the scissors trusses.

Evidently, the Conestoga sub-contractor Wayne Dalton can engineer and provide a solution but for an additional $2500.

Anybody out there encounter and solve a problem like this? How was it solved? How safe is it? Pictures of overhead doors installed within scissor’s truss spaces would help.

I’m actually tempted to cancel the overhead door and go back to a carriage style swinging door but have an idea that that option is really expensive.

What is the floor to ceiling height where the lift will be ?

I think you've come to the right place....there are numerous posts on this board discussing the exact topic.

If you are not looking to do this yourself, I would call around your area to places that specialize in overhead/garage doors. Tell them you want a garage door to follow a sloped or cathedral ceiling rather than going straight back. This involves a little bit of figuring out in terms of the drum used on the cables but it has been done many times before and shouldn't required $2500 for garage door "experts" like Wayne Dalton to "engineer". If you find someone who really knows garage doors it won't be a big deal and then I would bargin with your contractor to ditch Wayne Dalton and go with the company you find.

If that doesn't work, there are a few guys here that can tell you exactly what drums you will need to work with your slope and we can help you through installing them yourself. Do some more searching an you should fine some posts of exactly what you are trying to do.

Holy ****!!! Don't walk away from this contractor, RUN.

Try your local garage door company. I installed scissor trusses in one bay of my garage and had the installer run the channels as close to the bottom of the truss as possible. If I remember correctly, they ended up about 4" below it. It was a whole $20 extra. It's not rocket science and door manufacturers do it all the time.

My Wayne Dalton installer just gave me a price of $ 670 to covert my existing standard lift door to a high lift. I bet your quoate was to add another section, which you don't need.

I just ordered about $300 in parts from American Door Supply and plan on converting mine myself, just like I found on this site.

Most of that cost in the new tube and springs.

You can't use the crappy Wayne Dalton "Tourqe Master" torsion spring, you need standard 1" tube and springs. Then you can use a LM3800 jack lift opener. If nothing else, make them put the standard springs on it, call Doug at American door and convert it latter. Not worth $ 2500!

5wndwcpe -- At the point the scissor's truss joins the header, it is 10'-4" above the floor. At the interior peak of scissors truss, the height is 15' 9"

I really appreciate all the quick responses and help

Gotcha. Sorry, I had assumed they were like mine (which run perpendicular to yours). Carry on. http://www.garagejournal.com/forum/attachment.php?attachmentid=17797&d=1208535123
