D4 Recovery points

After some research
ARB recovery points are rated to take a 4750 kg rated bow shackle and using a 8000 kg snatch strap.
This gives me confidence in using the D4 "on road tow points" as off road recovery points - fingers crossed.

Which means if you use a standard 8000 kg or greater spec snatch strap you could have a shackle flying through the air.

Your standard recovery shackles are only 4.5T/4.75T

Hi Will
On the video didn't hear any mention about recovery points rated to 6 tonne.

In the full length version Land Rover Discovery / LR3 The Big Lift - YouTube at 1:43... "we already know that it's integrated body frame has a 6ton snatch recovery loading".

Rylee,

There are definitely folks here more qualified than me to explain about " rating".... but part of what makes the rating conversation confusing is that some "rating" that people discuss is a breaking strain.... e.g. snatch straps... my understanding is that that is the safe limit at which to use them, after which they are likely to break.

Other things, like "Rated" shackles are a safe working limit.( SWL or WLL) - this is related to cranes and lifting and I think has something like a 5 times safety factor built in...

Every wondered why you can use an 8 tonne snatch strap with a shackle rated at 3.5 tonne?... That's why.... the shackle is not going to break at 4 if pulled in the correct direction.


So I'm quite comfortable using the 6 tonne recovery points on mine if needed......but if you have to snatch very hard.... I'd suggest you should have used a shovel for a while before hand..[bighmmm]



Hopefully someone more qualified than me will chime in re the difference between breaking strains and safe working load limits

Thanks everyone for your input, it's been very helpful and informative.
It's good to have sites like this and people who are willing to help with their experience.
