D3/4 front and rear OEM centre recovery point rating?

[winaje]

Hi all, does anyone know what the centre recovery points at the front and rear of a D3/4 are rated to? Is there an actual rating from LR for these 2 points?

This may give you an idea Will, the 57sec mark of the vid:)

Geez some people are brutal to equipment they don't own or care about.

I'm particularly interested in knowing the load limits and strengths. As an example I might wish to recover a truck that's spinning wheels in mud but is not bogged to the axles. I'd use a couple of 4.75t rated shackles and a 12t tow strap, with no shock load. Using a tight strap gentle pull, am I likely to break the loop off the back of the chassis?

I realise that there are a lot of variables to the question. I suppose I'm just asking how strong the loops are for low stretch applications such as a tow strap or a chain, used sensibly without shock.

I pulled a bogged cement mixer up a slight hill on the rear tow point, using his recovery chain. The unofficial rating is 6 T.

And that would be SWL ( safe working load) and not failure load.

And that would be SWL ( safe working load) and not failure load.

As I understand it, failure load is normally 5 to 7 times the SWL. So realistically pretty much anything could be recovered provided it's not too badly bogged. Sounds to me like you'd have trouble with traction before you broke the rear loop, provided there was straight pull load without any shock.

This might give you an idea of the static load.

Judging by the covers over the panels I'd have a guess and say LR testing

Hope you weren't using a snatch strap. :p:p:p

:o:oNo Brian, it was a chain, 1st low nice and slow;). The car thought it was bogged and went into super extended mode! It won in the end.

Drive it like you stole it !!! :wasntme:

Notice, by the chassis rails, not the recovery point!

[Fred Nerk]

The reason you are not getting a straight answer is because there is no rating for recovery points. Shackles etc can be tested and rated, but there is no standard for recovery points.

At our 4WD club a year or so ago we had an ARB presentation. One product discussed was the ARB recovery points that can be attached to a variety of 4WDs. The presenter was at pains to explain that the supplied equipment could be rated, but not its attachment to the vehicle. Since they have no control over the angles that the recovery point may be pulled they are not prepared to guarantee that the recovery point will achieve a specified load.

I think the best advice is to keep the forces as low as possible and as straight (in line with the vehicle) as possible. And keep everyone well back.

You may want to look at the above video, because at the 1.47min mark, it tells you the rating for a snatch recovery on the Discovery 3!!

This is from all the testing from the first video, which is just a small glimpse from a LR test facility.

I have watched the video. The "rating" for snatched recovery load refers to the chassis/body frame . Not the recovery points. And as has been stated previously ,they do not use the recovery points in the video.

I stress again, there is no such thing as a rated recovery point.

True, this is not a recovery point test.

In the first video it is, if it's not, then the guy who does the training for the LROCS, is training people wrong, this is where I saw the full video of the one I posted on page 1, looks like they are using the recovery points, but I could be wrong, but it sure looks like they are.
