Well i now have a nice big 9 ton rated tow rope and 10 000lb tow hooks, I went for the highest rating I could find. Now I want to know how hard I can pull? Assuming of course that the person im towing has the same gear how hard can you go for a snach recovery and not risk breaking hooks etc?

Cheers Pete

Theres a real good page in Ken Siblys 4wd handbook (pg 195) that gives resistance calculations and the total weight that will be taken up when extracting a stuck vehicle its a bit much to type out lol

Cheers

Its got to be the golden rule of the minimum force thats nessecarry

The more force the bigger the risk of something breaking.... and the faster the bits traveling when they break :oops:

Im sure we all found that out back arround the age of 15!
And yes I know that you should use the smallest amout of force when recovering someone when 4wding (trying to cover everything there wopass) but when should you give up on snatching and try something elce. I want to know when to stop before I break stuff and someone gets hurt.

I think it comes down to common sense really and if it doesnt feel right then stop and fix what doesnt feel right ( dig a bit to remove some of the obstacles ) change angles, change recovery vehicles, inlist the help of another vehicle to reduce the shock loading, use a winch etc plenty of things to make things safer.

just my 2c

Remember if it dont feel right then something is probably wrong or going to go wrong.

if a gentle pull wont do it, find a winch. much safer.

3 vehicles linked together to pull the others up a steep sand hill

A few years back we were removeing some 100 year old Macrocarpa's on a property up the road, one of them was leaning over their stock yards so we were using a snatch block up in the tree and a couple of cruisers to de-limb the tree and lower the bits down and away from the stock yards before we cut and tirfored the main trunk down.

I was sitting in my truck looking at the short length of steel cable and a large shackel joining onto the main steel cable thinking that it dosent look too good for me if the cable breaks.... that was just before the cable broke and sent the shackel through my windscreen. I came away unhurt but with a new knowledge from that incident and have never attached anything to my vehicle that could potentialy put me or anyone at risk ever since. I don't even use the drivers side recovery hooks anymore either.

It didnt feel right and it wasnt right :oops:
