I have jate rings fitted to the ns and os chassis rails on my defender 90,i had to get recovered last week and upon washing my landy today i notice 2 dents on the underside of my chassis were a shackle which was attached to the os jate ring has been pressing against it during recovery,is this normal? what can be done to stop further damage? apart from not getting stuck! :D
thanks phil
 
thats pretty good,but i use my towbar regulary,and i thought jate rings were designed for recovery???!! anybody?? :)
 
I would wonder about the method of recovery, sepecialy if this has only happend after the one recovery, or the soundness of your chassis....never have noticed this before on mine or anyother that i have worked on.
 
the chassis is sound,its happened on the crossmember replacement piece,so no rot there at all! its were the shackle has pressed into the chassis as the jate ring has moved around :eek:
 
Chassis is only 2mm I think,maybe less.

The box construction is strong, but the plate itself is easy to dent.

Monitor it but a non issue of you ask me (which you are)

:D

Ya wrong then.:p

Jate rings were never designed to be used for "recovery" they were designed for Air transportation. As in been slung underneath an helicopter.. However I've never heard of a forged Jate ring failing during a recovery And have fitted most of my landies with them and always carry a spare set in my recovery gear. In case I have to recover someone, who doesn't have proper recovery points.

As said if they've dented ya chassis then it's probably a weak (rusty) chassis or over exuberant recovery techniques.
 
Has been known to tube the mounting point on Team recovery vehicles but they will only ever use the jate ring to recover a propper stuck motor as the last resort instead of the normal towball because its far quicker as your against the time. Never heard of anyone breaking owt unless as above fooked chassis. occasionally making the hole oval slightly but never ripped out unless fooked
 
the chassis is good,its a new 1/4 chassis! :D and its dented the underside of the chassis rail,the shackle attached to the jate ring has dented it :eek:
 
Maybe the repair panel isnt as strong as it should be? Often the repair sections are thinner.

OR it's just normal. If you took a hammer to the chassis you would dent it. A shackle under snatch load could do the same thing...
 
I would think that it might have something to do with what you were being recovered with. Perhaps a strop would deliver more of an impact to the chassis member as the recovery vehicle surged forward than a rope with a little elasticity would.

Under those circumstances it is quit possible that the impact from the moving jate ring might be comparable to a swiftly moving hammer, and the shackle attached to the jate would concentrate all that force into a single point of impact.

I know that on my V8, the holes where the jates were bolted in got a bit elongated.... but then I did get into one or two positions where a judicious use of power and torque was necessary in order to restore forward motion!:rolleyes:
 
i was properley stuck! :D i think the shackle dented it, gonna use my towbar for recovery from now on.
 
Very little aftermarket is suitable for snatch recovery, be it add on rings or even a factory towbar. The loads can be immense. Axle deep in mud a disco1 has an effective weight of at least 5 tonnes double that or more for chassis deep. That's the straight pull loading, add in the shock loading of a snatch recovery and 20tonnes upward would not be surprising. With suction and friction the effective weight for pulling can actually be greater than the lifting weight, so a 4.25 tonne lifting shackle will be well over its rated load and into the safety factor. A proper kinetic rope/strap is preferable as despite the immense loads possible there is less shock loading due to the stretch.

Jate rings are for lashing to the deck of aircraft or ships, just after-market versions of the peardrop lashing rings on many LR products. Just consider the position Jate rings are fitted, and the angles involved in using them for recovery.
 
Jate rings the ones you got which are typically £12-15 each and are not the tie down loops nor the inferior J A T E rings that the military sometimes use which are again for lashing down by those that go through the chassis with a bridal is usually more than acceptable for general recovery inc competing. Any dedicated recovery comps like Team
Recovery require a tow ball with appropriate spreader plates and strengthening.

But for laning, play days, RTV trials and CCV trials Jate rings are usually more than ok
