OT anyone know anything about elecrtic gate openers?

Been looking at several options on these but I am looking for brand recomendations and guidance.

Jeff, with your great fabrication skills you could easily build one.

No, you probably can't. I've been a dealer for industrial gate operators for fifteen years and can guarantee that there's a lot more to doing it right than meets the eye. There are standards now for entrapment protection that are pretty loose for prisons and industrial plants, and get mighty complicated for residential applications. You can install something without the protections, but will really have your butt in a sling if someone gets hurt.

If you're talking about a slide gate operator, there are chain-drives, cable drives and rail drives. The chain-drives (Stanley is the cheap one that gets installed most often in light-duty applications) are a royal pain because the chain needs to be lubricated regularly. When it inevitably isn't, it rusts, kinks and gets bound up.

Go to www.hy-security.com to see the line that I represent. Look for the Slide-winder line.

Yeah, I'll PM you some price info. The Slide-Winders are more than Stanleys, but I think not a whole lot.

Looked the link over Larry after I figured out it was there and that is pretty inginuitive. My problem is I don't have time to tinker anymore. Time has turned into money for me and I just have to get something I can throw on and go, although I am going to re read the link whaen I get a chance.

Jim brought up good points about the law... I'd not even considered those points. I've been tinkering with making my own automatic gate for years, but never have gotten around to it due to the expense.

Yeah, for a residential gate operator to meet UL standards it has to keep track of its problems. If it bumps into something as it closes it has to reverse to open, and can apply no more than some small force on the object it hits. After some period of time it can try again. If it again bumps into something it has to reverse to open and then shut itself down until a reset button is pressed on the operator. And it has to have at least two methods of determining that it has bumped into something. The operators I sell use a bump strip on the ends of the gate and a pressure switch in the hydraulic circuit, and some installations also use one or more photo eyes.

The rules are the same if it bumps into something when opening, except that it has to reverse itself for two feet and then stop. I might be off on the details, since it's been several years since I went through a class on that, but they're at least that complicated. That's to receive a UL listing, but if someone gets hurt by a homemade operator that isn't up to those standards there's going to be a mess of lawyers involved.

So does that mean having a hot wire on the gate to discourage intruders is out? Electrocuting thieves is Politically Incorrect now?


Seriously though. I've been wanting to put one on my chain-link fence gate.
Right now I wrap a chain around it with a lock. It's a PITA. Get out to open the gate, get in to drive through it, get out to close and lock it, get in to leave.


The automatic gate openers I've looked at have a key lock box so you can lock the electrics when you leave, but the motor chain/gear system is what keeps it closed. They have disconnects to manually override it.
That's not secure - a thief simply pops the pin and comes in.

I want to be able to physically lock it when I leave, not just electrically lock it. But that negates the whole idea of an electric gate - I still have to get out to do it.

Any suggestions? (Other than a guard with a shotgun?)

Brush up on your understanding of the Mantrap laws. I remember back in the 50's and 60's when the rage in California was to protect your vehicle by electrifying the door handles. It discouraged thieves, but if a little ol' lady with a heart condition brushed up against it, it could kill. Guess who'd be liable for that death?
