The chain is attached to the Tow vehicle as a load spreader for the strap.

The chain fails and launches backwards.

I thought that people had moved away from using chain to using steel wire cable for hauling stuff in mines, industry, and even for hanging the roadway from in suspension bridges due to chains failing suddenly without warning whereas cable would supposedly fray, unravel, etc as an early indicator. I only carry a length of chain to drag logs, trees out the way as it should bite better than a strap and won't be damaged, unlike using a strap as a drag chain.

I feels sorry for this bloke.

It happened to me once. I was doing advanced recovery course at club land and
The recovery involves a chain sling.
A block was setup on the top of the slope and a chain attached to both cars so that one car does downhill, while the other climbs up

The chain snapped and can't bt found anywhere. Luckily no one was injured.

Since then I decided to try my best not to be rescued or rescue another 4wd unless necessary.

Meaning if some idiot really want to go into that bog hole and knew he is likely to be Bogged. I will leave him happily

At that time we were all very picky about rated shackles and chains and believe if we use properly certified and rated chains and shackles, nothing bad will happen.
Unfortunately Not the case.

We used to spend days winching out stumps,when i was a young one, with the Tirfor.

I recon we pulled out hundreds over the years.Us kids used to have a comp,try to be the first to break the brass pin.

And hope the old man didn't have another one so we could go off and do what we wanted

We still have it,first Cape trip we thought we wouldn't need it.Anyway we tossed it in,and sure enough got badly bogged in a creek,it got us out easy as.Havent used it since.

Steel rope and Steel chains are nasty when things go pear shaped.

Steel is elastic.. it will certainly store energy...

Still use plenty of chain here in the mines for lifting operations. Its main benefit is they are durable compared to soft slings and wire ropes. But yes chains can fail suddenly - I remember a few years ago we had a lift where a chain failed with a 32t load. Lucky the load had only lifted a few inches when the chain failed which turned out to be a manufacturing defect - SWL of the rig setup was around 50t and the chain was practically new having only done 4 lifts in its life.
