Narrow escape from serious injury - a very worthwhile viewing.

I trust this is treated as educational and not turned into a witch hunt on the poor bloke this happened to. I read into his report and clearly see his mistake but thought proof of the failure of an inappropriate recovery technique is a worthy reminder to the casual/unwise.

I POST THIS IN THE HOPE THAT IT MAY SAVE SOMEONE, SOMEWHERE, SOMEDAY.

Take care out there folks.

Sorry people didn't realise it would be password protected. I don't know the technique required to get arond it - if anyone can advise me, I will endeavour to get it set up.

OK - can't grab the images that go with the report but the text is -
"Went for a weekend trip with a couple of friends last weekend down around the Arthur River region and had a good time until 2 mates got bogged in the sand nose to tail, i reversed back unrolled my ARB 11000kg snatch strap put one end on my bus and hooked the other loop on the cast iron tow hook (no shackles used) on my mates flat tray cruiser.
Went through a normal text book snatch procedure and "TWANG" the snatch strap hit my back doors and the hook which had broken went through my back window,ripped my roof lining,went through the sunvisor hit the roof, bleep tered the front window and smashed a hole in the dash and landed on the seat behind me.
My missus and i was the only people in the car and are very lucky to be alive. Everyone was so shocked on what had happened we packed up and went home with a horrible gut feeling of what could have happened.
Upon closer inspection of the tow hook we found that it had a tiny fracture where it had let water in rusting on the inside making it weak. After the trip all 4 4wd owners have removed there old hooks and replaced them with new ones.
Even though we used all the correct recovery equipment accidents still happen. I have sinced learnt from this accident that i will no longer carry passengers on a recovery mission and am installing a cargo barrier to hopefully stop any objects from coming through from the back (hopefully never again) .
The over all damage was $9000 which is nothing compared to someones life.
I urge to everyone check your recovery gear and hooks regurlary because i would hate this to happen to anyone else."

obviously you are a member or registered to get access to the 4wd site.
contact them and see if they will release the details and images as a community service.
we all hear about incidents like this but without the "proof" a lot think they are urban myths like the winching of vehicles in half.

regards peter.

on a recent trip we came across a group of 4wders that had a vehicle very stuck and noticed them using a d shackle to connect the snatch strap to the car.
we suggested they not use the shackle and received a serving from the group, they became very aggressive and repeatedly told us we had no idea and to go away, in much more confronting terms.

this is the kind of people who end up doing damage to there vehicles or them selves but they wont hear the opinion of others because they know everything already.

there is no teaching people like this and i have taken the opinion to leave them to there own devices and stay far away from them.

Keith if the 'D' shackel has a WLL rated to 3 tonne or more (approx 25+ tonne breaking strain) can you please explain what the problem is with connecting the strap this way? Other than a suitably rated 'D' or bow shackel, what other options does one have for connecting a snatch strap to a recovery loop or ring?
Cheers Craig.............

For example Keith how does one attach a snatch strap to the red rated recovery point without a shackel?
Is the 2nd photo of a popular after market recovery hitch dangerous because it uses a bow shackel?
Personaly I have never heard or seen of a rated 'D' or bow shackel failing that was connected to a snatch strap simply as straps have far lower tested breaking point of around 8 to 9 tonne where as a 3 tonne rated shackel (with a safety factor of 8) is known to break between 25 to 30 tonne!
It's not the shackel that is the problem rather it's when they are attached to under sized tie down loops or damaged recovery points that they can become a missile.
It doesn't surprise me that you were told to go away :-)
Cheers Craig..................

Craig is correct joining the strap to the proper recovery points with a shackle is fine.

Its the habit of joining two or more straps together with a shackle thats not the done thing.

"Most" people should not weld anything to their chassis. The red bracket is supposed to be bolted (you can see the bolt holes) so why has it been welded ? I have seen many welds fracture due to both bad welding and where heat weakens metal around the weld. Also, in some places welding onto a chassis is not legal. Unfortunately it can be difficult to distinguish between cast and forged tow hooks.

Recieved the same dint in the tailgate of our old 60 and that was with out a d on the end just the end of the strap. Puts shivvvers up the spine when looking at the above pics.
Stopped some idiots years ago from hooking on the the front of their bull bar. Should resend the pics on the forum.

1. Get an extra tree trunk protector & thread it through the loop in the end of the snatch strap (& or shackle if one is used) - do each end of the snatch strap.

2. Attach the two loops of each tree trunk protector to another point on their respective vehicle. Ideally a second recovery point/tow point on bull bar, but a tie down point will do if thats all that's left.


If the attachment point on the snatch strap fails then the tree trunk protector arrests the motion of the loaded snatch strap.

Another alternative is to triple the tree trunk protectors up and use a few cable ties to keep it that way. You end up with a 1 metre strap and if it gets loaded up the cable ties will let go giving a three metre safety tether.

Works well. Takes very little extra time to setup.
