Recovery Points - Load Ratings

[Arkaig]

I was interested in finding out about the load ratings for both straight and angled pulls of the recovery points on the Grenadier and have been given the following information which may be of interest:

Clearly built for purpose!

Very interesting. Thank you

@Arkaig
Where can you find drawings like this?

When I look at the headlights, it seems to me, that they achieve the asymmetry by just installing bezels (the green things).

This wastes some light, but on the other hand allows for 'unisex' design for both, LHD and RHD traffic.

The front towing eye centres are some 800mm apart and the rears some 1110mm, for anyone interested having seen Robert Pepper's video:-

I measured the distance between the recovery points to determine the ideal length for an equaliser rope.

Front = 780mm so a 5m equaliser rope would be fine.

Rear = 1130mm so a 5m equaliser rope would be OK, but you’d need a 7m if you want to keep the angle to 20 degrees.

That would be nice, but are you referring to the small cutouts? Aren't they for the headlight adjusters?

In all the factory footage I've watched, I've only ever seen them on the lower right hand side.

And whilst these units appear bespoke for Ineos, the low and high beam elements appear very similar to their catalogue items which, unfortunately are all handed.

Excellent: but what is the sideways load limit when using a bridle to distribute the load? (as per

View: https://www.youtube.com/watch?v=V13ARMYoAos
). Have Ineos calculated this?

 

[Arkaig]

Have Ineos calculated this?

Probably not, why should they? It's pretty theoretical with infinite variables and of extremely limited practical worth.

When using a bridle, there are significant side loads on the anchorpoint. And simple "sideways" pulls are sometimes required in recovery. I am sure the Grenadier recovery points can take them: just interested if they had done any calculations

Just received two of these Beauties from George 4x4. Crazy that these were cheaper (including postage!) than any I could find in the US (seems like here, people are using tree saver straps, which are not ideal!)

Australian made Sheathed Bridle Rope 13mm*14000kg, 4WD Recovery

Bridle Rope is made of a unique ultra-high molecular weight polyethylene material(UHMWPE), also known as Dyneema/Spectra. Extremely high-strength and low-stretch. UV resistant, waterproof and more durable Very light, can float in water. Both ends have protective sleeves and are fully sheathed...

George 4x4 is where I buy my recovery gear from.

The info. I gleaned on the recovery points was that they have been designed such that individually they can support the full GVM and that the chassis torsional design will accommodate this without distortion.

Indeed...."clearly built for purpose" !!

Is it possible to have figures. The attacment from #arkaig gave horizontal (I guess front) and vertical, but lot lateral (sideways). I would like this quantified also! (I am sure it is more than adequate, but why not quantify, as sideways pulls may be more common than vertical!

I searched in vain for a front 5m and a rear 6.5m proper bridle here in the UK. In the end I I floated it past Red Winches as was ordering other bits n pieces from them and they said one of their 6m tow straps would be adequate for bridle. £19.70 + VAT. Should be ok for occasional use.

Yup: That seems to be the position here in the US as well. No one is bothering to mahe "proper" bridles. The problem with using a tow strap is that the main line will not be able to slide as easily to accomodate sideways pulls.
But it is "doable"...... (and certainly a cheaper solution!)
