Tragic for the family and friends, another young life lost :( :mad:
The flying towball often gets mentioned with snatch strap incident. The really dangerous bit of equipment is the snatch strap.
Too ealy to say but the article from Tasmania talks about the towing assembly and other bits as well as the ball. The one common item here is the snatch strap. Snatch straps need a big warning and perhaps buyers should be licenced to use them.
The towball is rated to 3500 kg as a max towing weight. Including a suitable safety factor on top of the acceleration/deceleration force when the trailer pushes against the towball (reduced with braked trailers) and the ball should be able to handle significantly more. Have a look on the front of 4wds that have lifting eyes on the bullbar. What are they rated to? Are you any better off using them to recover with?
Perhaps what would be useful is for someone with real expertise in this area to write an article, with pics, demonstrating how to recover a vehicle that does not have a specialist recovery point fitted. They are the vehicles most likely to get into trouble, and are the least prepared for it.
If such an article already exists, it might be useful to have a link to it.
Moderators, might it be worthwhile having a 'table of contents' page with links to such resource articles that are either part of this forum or on other useful websites?

Not all tow balls are rated, and of those that are, not all are rated for 3500kg. A lot of the cheaper tow balls don't have a rating, along with a lot of the older ones. The majority of 4wds have a hitch receiver type towbar, remove the hitch, put the strap through the receiver and use the pin to locate it. I have seen bent pins before, but never heard of one snapping. If it did happen to snap both sides of the pin would still be stuck in the receiver and only the strap would fly out. A strap on its own is not particularly lethal, but attach a solid object to the end of it and it's a whole different ball game. If I had a towbar that wasn't a receiver type, I personally would be removing the towball and then inserting a rated shackle through the hole to attach to. Even a 3.2T rated shackle will not self destruct until more than 16T of force has been applied to it.Quote:

I don't know if receiver pins are 'rated' either (never seen any evidence of such). Without doing the sums, and assuming similar metallurgy, would suspect a towball in single shear has a greater capacity than a receiver pin which is loaded in double shear due to much greater section size. Howeve the consequences of towball failure are probably greater, (unless you use the ARB insert)Quote:

Such a sad loss, I doubt people would have been thinking clearly about where they were recovering from that early in the morning.
A hard lesson learnt about recovery points and 4 wheel driving.
Blaze sorry to hear, your community has more than its share of tragedy involving young people.

That last sentence says it all. Most think that they are using the snatch strap to pull the vehicle out whereas what you should be trying to do is to put enough stretch into the strap for it to do its work on its own using your vehicle as the anchor.Quote:

Another thing to remember is for those of us who go on AULRO trips is that AULRO is not a 4wd Club and therefore has no public liability insurance if something goes wrong. I know that safety is paramount in any case, but if the worst happened because an AULROian did something like recover off a tow ball then the administrators could be liable???
As we represent an organization whilst on AULRO trips, we are required to do the right thing, so if you cant follow some simple rules, you have no place here.

A terrible loss, but totally preventable. incidents like this are really not 'freak accidents', they are just waiting to happen with incorrect recovery techniques.
Condolences to all feeling the loss.
