Roll Up Warehouse Door Woes

If it's an electric drive, there should be limit switches in the control box for upper and lower stops. At least that is how my doors are set up.

If it's manual then I am not sure how it is supposed to stop except for stop pulling on the darn chain.

If there is an angle at the bottom of the door you could put stops on the top of the track to prevent it from going farther up.

I'ts manual, old and been in use for 30 years, AFIK.

The numerous tenant's workers were just careless, I'm sure. Common sense was not abundant.

I can have it replaced, but it still appears to be serviceable.

The current tenant is old like me, pays in advance, and understands how to keep this from happening again.

It's the next occupant I'm worried about.

If that is the case , have it replaced. Maybe it's reached its service life and a replacement is due. Besides, you have a red barn to think about.

"Common sense was not abundant." ……. Seems to be common when it comes to roll up doors. I just spent $13,000 on a pair of our doors because the hilo driver was pulling something out and went too high and lifted a door with the mast guard, backed out, ripping both doors down along with the block and a half wide column between them and both headers above them.

She said she didn't know what happened, bricks just started to fall for no reason.

The same driver messed up a dock door last year by hanging the 3 foot long hook used to pull the dock plates up, on the track for the door. Then she tried closing the door. Always fun getting a call back to work at 11pm because they can't close up shop do to stupidity.

Does she still work for you?

Unfortunately..... she came with the foundation, she has been with us for almost 40 years, longer then I have been working. I think she would have to burn the building down before management would get rid of her. I just wish they would take her hilo license away.

Along that same line, I just had these installed over three roof drains at another warehouse because fork lift drivers tend to drive forward until the hit something that stops them before they drop a load.

Find a local lad who knows live from neutral, and has a bit of the clevers. Even with a manual system, a limit switch and a contactor ($30?) and some rewiring should stop this ever happening again.

Thanks, but the mechanical stops need to be reinstalled/replaced.

George will be out next week. He's installed complete doors for us and is reasonable.

And it lasted 30 years, kudos to the people that work there.

when I worked in the ship yard, we had a 20’ door that was beat up, we replaced it and on the first day after it was replaced, a 3rd shift forklift operator raised the door just 4’ short for clearance for the mask on the forklift. Coming into work the next day and seeing the result, one could only shake your head.

1st shift operators worked on project fire drills,

2nd shift was our most productive shift

3rd shift workers.. I’ll just leave that blank…

Not your every day limit switches. Usually they are rotary type for both upper and lower position. I've never adjusted one. Best call is to someone who knows about them.

Might need to make it.....can't find em anywhere....

Like these.

Clarification. "I" am not going to "do" anything except call George, or not. If I call George, he will come out and either repair the old door or install a new one. If it's a matter of installing a $5.00 stop on the chain, I might do it, or I might not.

I'm just looking for Doorman to say if he thinks it's simple, or not.

The current tenant can deal with the door, because he's old like me and understands mechanical doors.

Thanks!

Yeah probably just a service charge and some small part....

The edit system is a bit buggy. Trying to take advantage of the extended edit time, said I had 8 minutes left - cool! A minute or two of editing, submit... sorry, out of time.

Anyway, an image of the suspect piece can be seen in step 22 of these general instructions:

OK! I'll call George and have him come out.

No need to replace the entire door.

Thanks. I knew you would know what was wrong.

George will have his own ladder so I won't have to use the fork lift and a pallet to lift him up to work on the door.

Lynn, you didn't say if this was your warehouse,

I would call George. More than likely he not only has the needed tools, but he might have experience with your system.

Was the dent on the cover housing from reinstall or initial ?

It belongs to an out of state friend. AFAIK, the dent was from a former tenant.

I very likely will call George, just waiting to see if my friend wants a new door installed.

He just spent $30K having this and the adjoining building repainted, so money is not the issue.

Is this the first time it has happened in 30 years?

Something simple just gone wrong. It seems to be an easy job of fixing the limit switches or the door stop - or a notice on the switch that say 'stop when open'

It's a manual door.

My history with the building only goes back 17 years, but yes, first time.

Yeah, but have you tried limit switches?
Del (scampers off stage left)

He could wire the limit switches to a power source so when made, it sends a "mild" electrical shock through the chain to tell you to stop pulling on it.

Mystery solved; door fixed.

It was some $20.00 doohickey at the top. Probably that bell thing like Doorman said.

Thanks!

Cool beans!

I enjoy complicated, marvelous and wonderful solutions, but sometimes the simple, sensible and mundane solution is the one to roll with.

At the end of the day, it’s just a door, man.

These guys are the kind of guys you want to deal with.

They came in, looked at the door, saw the problem and fixed it.

I asked him if he wanted to quote a new door and he said, "no, there's nothing wrong with this one."

Thanks.

Well, at least it wasn’t the upper limit switch - those are pretty expensive!

Yeah. I tried to find the breaker for the door circuit, to see if it was tripped but couldn't, so I called George.

I still really like the limit switch connected to a power source idea, think I will implement in my shop. Maybe I can figure out how to configure it to the fork trucks and prevent our psycho hilo driver from ripping any more walls/doors down.

Can you just get those "shock collars" that are OSHA approved?

May be teaching my grandma to suck eggs, but remember to only cut the power when driving up (otherwise it won't drive back down!).
