Gate that hinges/latches at both ends

[Xiaomi]

Hi.

Looking to get a gate made for handling facilities and to make the most use of the area I want a gate that I can swing from both ends.

Has anyone seen any good implementations of this? I've seen some which have eyes on each gate end, but to open you have to pull a bar up the full length to 'unlatch' it. So, not handy when shuffling stock about.

I had an idea based on a latch like on current gates but it looked like it would jam easily and might not be handy to latch again. So hoping that someone will have already figured out the best solution for this!

Thanks.

If it’s only for livestock then make a 7-8 foot high U shape frame hinged one end with a gate hinged inside it from other end, inside gate opens one way, whole thing opens other way. As long as the internal gate is closed when other one is opened then it will be supported.

leek market has them old as the hill's but seem to work!

Rather than having to pull a pin the full length, just have the eyes on the side of the gate few ft apart so all it's just a 3ft odd pin you have to pull?

The best option which is also the hardest to do is to put the eyes on the posts. Then have 1"-1.5" pins top and bottom each end that move up/down on a lever system. Bit of engineering to get it right but it will pay off in the long run with how easy and quick it is to change which end it swings from.

Used to have an old cattle crush, bush eyes on gate and frame, locking pin was cranked and ran through frame bushes so only had to be moved up 3 or 4 inches. The middle part of the rod was shaped to be the handle.
Have been thinking about this way for a sheep handling gate which would be handy if opened either end, only need it to swing 270degrees or so.

Initial crude sketched of where my thoughts were. Although I do like the gate within a gate idea. Hasn't considered that.


This is just a dropper sketch I done at dinner. I think whatever way it is done there will be an issue with sag and you'll have to lift the point in the gate back on to it's eyes.



The one above is based on a conventional gate latch. I think this would be the most tricky to setup to get right and avoid impingements.

I think that sounds like my sketch above?
Any photos of it by chance?

Maybe sag could be countered by a long hanging post with a steel cable from the top of the post to the end of the gate? I've probably missed the point completely but I am always looking for these features on cowboy films!

Is this the same problem being discussed?

The only way I think it can be countered is to have a wheel in the centre of the gate. I've got a 9" wheel rated for 1000kg, but I'm not sure how you could get the depth correct.
I could probably have it on a threaded sleeve, but it really is getting into serious fiddley engineering for a crush gate.

Yes, exactly the same. However, I'm aiming for a mechanism to latch/unlatch that would be quicker than that setup.
Can't figure out what the setup in the green gate is though.

Looks like the dropper design I had put up and @JockCroft mentioned.

Our market has some gates with hurdle type pins and the bosses like in your picture @Xiaomi on the pins. The gate hinges then have cutouts in them bit like a brake pipe spanner.
Similar to your idea but one straight rod that needs lifting 3-4" to open the gate.

Mkt at Ross on Wye has gates with eyes both end and a lever on the posts which pulls short pins up to open. Probably the same as @bravheart mentioned and @Xiaomi drawing. Would imagine they'd be IAE as everything else at the mkt is

You wouldn't be able to get a photo of it by any chance or if the are IAE as @Bald n Grumpy thinks?

No idea who made them, they are on the loading/unloading pens. Pens can be filled/emptied from either direction. They need to be kept well greased and some need a wee lift before they click home. Gate inside gate may be better if you need them to slam lock.

@bravheart - so the cylinder on the dropper sits snugly inside the eye on the gate and you only need to lift it enough for the cylinder to clear the eye to latch/unlatch it.
That's a really elegant implementation. Not sure though how the eye would hold up to cattle pushing against it - although it does look to be quite chunky.

Gate inside gate - I've thought about this a bit more and for it to work for me, I would want no fixed bottom bar for trip hazard. There would need to be an access hoop at the latching end of the inner gate to walk though without having to duck and there would need to be some type of bump stop on the bottom of the latching end to prevent the gate sagging in on itself when the outer gate is opened.

I've got some options now which is good.

The second drawing looks like the implement locking mechanism on a front loader. You might be able to copy the dimensions from there.

I used the term hurdle pin but the ones in my picture are much heavier built and stronger. Does mean some don't auto latch and need lifting slightly before the pin drops.

As @Mur Huwcun says above make a gate inside a hinging U frame of 7-8 feet high or whatever height you fit comfortably under, no need to complicate further and use threaded hinge eyes to take out any sag.

Chain arrangement looks pure IAE.
