Attaching a bridle to Jate rings ...

[mojo]

Just wondering if any of you use Jate rings as front recovery points, and if so how do you go about attaching a bridle to them? I don't like the idea of using a shackle to attach each end of the bridle to the Jate rings - it seems to me that would create a very small and highly stressed contact point of metal on metal.

The other option would be to attach one end of the bridle strap to a Jate ring by looping it through itself, but you wouldn't be able to do that with both ends ... do you use two short straps looped through each Jate ring, then join them (and your snatch strap) with a shackle? :confused:

Hopefully someone out there has a Jate ring setup and can answer my silly question ... I'm sure there's probably a simple answer staring me right in the face ...

Cheers

AS a dogger and a crane operator I wouldnt be worried about that little contact patch...

On a regular basis I see shackle to shackle doing exactly what your worried about doing and not with the paltry loads that a bogged rover is likely to generate (well maybe if it was down to the roof but then how are you going to hook it up anyways?)

on that note chain does pretty much the same thing anyway.

The ADF doesnt get paniced about it either and they do things like strap em down in aircraft using shackles and straps to the same points...

If its good enough to hold it in a multiple gazillion dollar star lifter, galaxy or hercybus I reckon it'll do ok for a recovery job.

Thanks for your opinion Dave.

arent jate rings slipped over a pin and held with a spring clip....?

you cant thread the ring through the ends of....say...a tree trunk protector........?


got a pic of the jate rings.....?

No, Jate rings are generally attached to the chasis as a recovery point - most people use two of them, with a bridle hung between them to equalise the load, and the snatch strap then attached to the bridle. My query is how best to attach the bridle to the Jate rings.

Sorry Defenderzook, I just re-read your post and I think you might be thinking of these? I would like to use one of these but it's going to be alot simpler for me to mount the Jate rings to the chasis than one of these suckers ...

I agree with Dave .. there is very little chance of a rated shackle breaking before the actual recovery strap or rope.

The problem with running a loop through the jate ring is with water and mud it might pull so tight that you can't release it again without effort.

I've used shackles on my jate rings on a number of occasions without issue. The only place where you don't want to use a shackle is to attach the bridle to the main strap. This increases the risk exponentially as you now rely on the strength of a strap to keep a shackle in place.

Dont see any option but to use shackles on that setup. As said should be Ok as long as its a properly rated shackle and you don't go silly with the snatching.
You can use a tree trunk protector as a bridle - thread it through the loop on the end of the snatch strap - then there's no third shackle needed.

You could unbolt the ring from the chassis then thread the snatch strap through the bridle and the bridle through the rings and then bolt them back on again.

You'd have to be keen though.

Thanks for the advice guys. Sounds like rated shackles are the go then.

Of course, I am driving a Landy, so I should be able to avoid having to use them at all :p

Thought about that, and yeah, I'm not that keen ...

Go to a lifting/crane supplies place and get a couple of proper Bow Shackles. I picked up a couple of 4t ones for $15 each. They cost a heck of a lot more at 4x4 joints and they my not be correctly rated.

And thats 4t, with a vertical lift, more than enough for my 1.9t series 2a. Besides pulling horizontal is less of a load than vertical.

One of them and a 8000lb winch and I should be able to climb a tree in the old girl :D

By looping the strap back through itself you are reducing it's Safe Working Load (SWL) or Working Load Limit (WLL), in this case looping around a "round" object reduces SWL or WLL by 1/3, if it was looped around a square object it's SWL would be reduced by 1/2. Using rated shackles (with SWL or WLL stamped on body) will be the way to go.
Keep your bridle as long as possible, keep the angle formed below 45 degrees if possible, increasing (using a shorter bridle) the angle above 45 degrees puts extraordinary strain on the strap as the 2 anchor points are trying to pull your chassis rails together. Most people think that by doubling the bridle strap they are doubling it's weight capacity, if the 2 anchor points are together, i.e. no gap between the ends then SWL capacity is doubled, but if you spread the anchor points wide apart then the greater the angle created the greater the tension is, which reduces the SWL or WLL, so be careful and think about what you are doing when doing recoveries, Regards Frank.

no.....i was talking about the jate rings......but i thought they had a pin that ran through the chassis rail......
with a little locking pin running through that.......very similar to a tow hitch locking pin.......
i just thought that jate rings were free to swing back and forth for some reason.......

so....you can scrap what i was thinking......it wont work...
