Installing a chain hoist on roll up door?

[Hobby_Man22]

I looked at videos on YouTube and most people have the shaft sticking out more in their door. Mine only sticks out an inch or so.

 

[PoorUB]

Huh?

 

[Hobby_Man22]

I want to know how to install a chain hoist on a 10x10 roll up door.

 

[Dagny]

I dont get it

 

[racecougar]

Why?

EDIT: Are you talking about a chain operator to open/close the door?

No, a chain to open the door.

 

[racecougar]

If both sides are cut that short, I'm not sure that you'll be able to install one without getting creative.

 

[Hobby_Man22]

Why are they so short? Did someone go back afterwards and cut them?

 

[brownbagg]

thats fine, i did it with mine, the chain fall slips over the nub and you drill a hole and add a bolt

How hard are these thing supposed to be to open? It's pretty hard to both opening and closing. Of course it doesn't help that the rope broke off.

So that should slide over the tiny 1" nub that's sticking out?

has long as there enough material to add a bolt

Two things come to mind looking at your photo.

Does the shaft turn as the door opens? In the photo it appears that the shaft has a through bolt holding it to the bracket. Some are not engineered to accept a chain fall.

The insulation is also likely adding to the drag opening and closing.

It added a little bit, so I tightened the spring some and that helped. It wasn't staying up all the way before I added the insulation. How hard should it be to lift? It feels like I'm lifting 50 pounds when it's at the bottom and I'm bending down to open it. Gets a little easier as it goes up.

In the ideal world it would be so balanced a finger would open or close it. As far as what it should be, that's subjective. You don't want it to move too easy either direction.

So I can go ahead and tighten the spring more?

On that style door you have to order a different door set up to use a chain lift, the shaft does not turn the door operator spins on the shaft.

 

[brownbagg]

if the nub not long enough , just add a piece of pipe to inside of nub and fasten unto it with the chain hoist

Ah! Confirmation that I wasn't hallucinating.

 

[Hobby_Man22]

Are these just some cheap *** doors the previous owner used.

 

[Wrench97]

No they are actually a pretty decent door, but if hit and bent they do get hard to open and close(my experience with them is on a freight dock where they get hit by forklifts and freight)

 

[Hobby_Man22]

They aren't damaged.

 

[Hobby_Man22]

I just wish they weren't so heavy to lift

 

[Wrench97]

When working correctly they open without a issue, if they are old and seldom used there could be a corrosion issue in the operator or the spring has stretched and needs to be adjusted.

 

[mogandave]

It should roll up and down easily. I would figure out the make and model, and get the documentation to service the door. It likely needs lubed and adjusted, including the spring. DO NOT overtighten the spring to overcome a lubrication/bearing issue and do not remove anything unless you know what you're doing.

Or, you could get a tech out to do it. We used to have a service that came out, checked and adjusted all the doors a couple times a year.

 

[Hobby_Man22]

The spring was barely tight enough to hold it up before I put the radiant barrier on. Then that made it not want to stay up on its own, so the spring isn't that tight. It tightens when you close the door and has less tension when it's up all the way.

Okay I turned my brain on. I installed brush seals and it's the brush seals making it hard to open. I still don't see why I can't get a garage door company to weld a sprocket to the shaft to install a chain style opener.

The shaft is fixed. It does not rotate. A standard chain operator will not work. If you want to be fancy you can get one of these:

Automatic Technology Dominator EASYROLLER Sheet Door Operator 86063

It will require a longer center shaft to attach to. I would just weld some steel tubing on the end to make it longer.

Here is my thread that has some details that may help you:

Residential Roll Up Door

Figured I would make a thread about my roll up door install. My workshop was built by the original owner for a woodworking shop and I guess he decided there was no need for a garage door. He had installed 2 French doors. I need to be able to have a bay to work on vehicles and I am installing a 2...

Gargae door companies aren't welding companies. You are talking to the wrong people if that is what you want done

unless your insulation weighed a ton or its hitting something you should be able to tighten that spring so it opens with a couple pounds of force only. no exertion. just be careful as it can kill you if whatever you have stuck in the holes spins and wacks you. i have those doors and i don't have any issues with either of them after years of use. a chain style is for ones that don't have a spring inside.

It's the brush seals i installed

I did give the spring a few turns to make it a little easier, but I'm not sure how good of an idea it is to tighten it up to overcome the friction of the brushes. I don't want it to break when I have my hands on it trying to tighten it up.

 

[adsinnott1]

I have brush seals installed on mine and they did not add any noticeable amount of friction. Are they installed too close to the door?

It's possible.

 

[Hobby_Man22]

I'm going to just have a garage door company look at it. I've seen videos of people lifting these things up with 2 fingers. Maybe the people who installed the doors didn't put enough tension on the springs.

Unless I missed where you changed the doors, you still have the problem of the fixed shaft. You simply cannot rotate the shaft to operate the doors.

The system posted by adsinnott1 is a solution that would not require a door change but would require lengthening the shaft some how.

 

[mogandave]

The door should open easily.

If the door does not open easily, it's not a design issue, something is wrong with it.

Having a door guy look at it is a good idea.
