Surely that cant be right? So a landy with two wheels spinning in sand will require the same force to recover as one bogged to the bonnet in mud; or did I miss understand ?

think you have misunderstood him. The force required to extract a vehicle depends on many things including weight of vehicl, how vehicle is bogged, gradients etc.

Strongly suggest people read this link

Pirate4x4.Com - Extreme Four Wheel Drive

Extremely useful.

Having a google have found a couple of interesting sites

Snatch recovery

and

Snatch Straps

In the second one there is a diagram showing how to connect straps together which I was trying to explain earlier. Instead of a piece of wood use a rolled up newspaper/ flouro vest/rubber mat etc.

In the UK the swan neck tow ball is more common then the bolt on tow ball. IF you have to use a tow ball get a shackle which will fit around the neck of the tow ball but will NOT come over the ball.

Not all straps are made from the same material, although it is highly probable that all snatch straps are made from nylon. There are many grades of nylon and they all have different properties as a base material. The way the nylon filaments are spun and drawn will result in different physical properties. Then how the strap is woven together will dictate the final properties of the snatch strap.

Therefore it would be unwise to assume that different snatch straps have the same elastic and physical properties. Variability between batches from the same manufacturer should NOT exist BUT if they outsource theit straps/webbing from different sources then you will have differences between batches.

Once had to investigate why certain polycarb components were failing. The company was not happy with our basic conclusions which were ignore your bean counters, stick to one relaible supplier of polycarb and keep an eye on the molecular weight, and finally keep to one good moulder! The quality control had gone through the window as the bean counters did not understand polymer science! Cheap does not always equal good.

good point, so even two 8000 straps will not have the same elasticity.
Never thought about it

Yep, and I am not condoning incorrect application. They can be lethal but if used in the correct application are fine. If there is any risk of the attachment point breaking or the main anchor point is a strap or just joining straps they should not be used.
Like I said if used on a correct closed recovery point they are worth their weight as there is no way the strap can come out apart from breaking.
Oh and yes I do use recovery hooks, ideal if a quick recovery is needed or you are trying to hook up under water or mud.
But like on our trucks etc that have closed recovery eylets I will use the shackle. If a shackle breaks you are in serious trouble anyway.
I have seen them used incorrectly many times and stopped many.

Just got back from Fraser.

I was amazed how many people dont throw anything over the snatch strap, dont use recovery points, use old snatch straps, some with knots in them, use tow ropes to pull 4x4's out..
I even saw one guy about to join two with a shackle.

So many people also use the tow ball as a point. I tried to tell a guy not to use it and he said its fine. He knows how to wrap the strap around the ball so it wouldn’t fly off!

Was very interesting.

I got bogged twice. used MaxTrax both times to get myself out. I was running tyre pressure at 22PSI.. prob should have been at 18PSI

Thanks

That's not the first time I've heard a G string called that.

Depends how energetically you dance I spose, the main problem would be when you go for the big point at the disco ball, are white suits still the go?
