Winch plate. Apparently the pin has a shear strength of about 6 tons, but you can get ones that are rated to 11 tons, both will handle a lot.

So, my Hilux with the Loop on the chassis rail in the front is NOT a recovery point?
Are there any factory fitted recovery points then?

Correct.
Fearless had the same loop. It was the first thing to break off...

OK XJ. I am referring to the thingy in the photo where the arrow is pointing to.

Raait. I had my beer or two and now I want to mention a few things about this 'rating' thing mentioned a few times.
We 'rate' engines, horse power and torque. So we all buy buy the vehicle with the strongest engine. (like the Amarok V6 and Tuareg. :lol: )
But the guys that lift heavy things needs to know how strong eye pads and shackles and cables have to be to safely lift stuff. They rate their lifting gear. There are two ratings. Onshore and offshore ratings. Offshore ratings are more strict. There is very little little info on these ratings. But the Danish ratings and guidelines is the most complete. They have have standards for this stuff.

There are two kinds of shackles. Rated and non rated. It is like buying Nike tekkies. Cape Union Mart and the Chinese Nike tekkies. One off these two suppliers tekkies have no credibility. They are not 'Rated'. True Nikes are good. Chinese Nikes are not good.

There is a lot of tech specifications being thrown around here. Having "rated" recovery points fitted to a vehicle means absolutely nothing if the mounting method, -materials and -point are not "rated" as well. Who "rates" the recovery points on an aftermarket bumper?

There is nothing wrong with using a professionally built SABS (or similar) certified towBAR (not the ball) for recoveries if a decent recovery point is fitted to it properly. Those that fit into the receiver are great as long as they are fitted with the correct pin/bolt.

SABS certification means the towbar needs to undergo a 100 000 cycle stress test. This means the towbar is mounted as it would be on a vehicle and a hydraulic ram is attached to the hitch point and the bar is flexed through 100mm 100 000 times. Any cracks or damaged welding after the test and it goes back to the drawing board. Very few locally manufactured towbars are SABS certified - the suppliers and fitment centres bluff clients by fitting a SABS certified tow ball. The SABS logo will be stamped on the towbar itself if it is certified. BOSAL and one other, that I cannot remember the name of, used to be the only local manufacturers of SABS and OEM certified towbars. The smaller manufacturers just cannot afford the certification.

RooiTjiep has an OEM "recovery point" attached to the chassis - closed loop 10/12 mm, welded onto a 12mm base that is bolted onto the chassis with 3 12 mm HT bolts at 2 angles. Fred Bartens, the training officer at the AWDC at the time when I was a member, was quite happy to approve this for snatching and after being snatch recovered from belly deep mud on at least two occasions, there is absolutely no distortion or deformation, so I am also quite happy to use it. The "recoverer" will have the last say if it needs to be used, though

I am a HSE advisor/medic on a Norwegian vessel in the seismic oil and gas industry. Let me know if you want the Norwegian lifting standard. As you say, it is very very strict! Even out slings and shackles are on a lifting register that requires annual re-certification by a governing body.

I think all this talk about 'rated' stuff is to ensure one gets good quality things like shackles and bolts. A lot stuff is available out there but we don't know the quality of these things. See the 'towing hook' on my Jeep. It looks good but I am not sure if one can snatch from it. Therefore I won't.

The biggest issue is people use equipment without understanding exactly how to properly use them .
Recovery points as stated above need to be as wide as possible .
Shearing of a bolt hasnt been seen or experienced by many .
Its scary .
Spreading load under stress is very important .
Now that you mention this. AndreasR went on an overlanding trip a few weeks ago and he wrote an lovely trip report. This happened to them on that trip.
I hope Andreas don't mind me quoting this. It is all in the name of science. :)

I have actually done a pretty decent recovery of those Oom Chris, but a pull and not a snatch.

Have winch will use though.

I think I should have mentioned that those things of mine is on top of the front bumper and not at the bottom underneath the vehicle like the others are.
It seems that they are meant for recovery.
