Thread: Where to put the winch vehicle?

Next point is the bumper/roo bar arrangement interfering with the recovery strap. The principle component of force fully in the direction of the recovery strap. If the strap is deflected by the bumper there will be a minor component of force in the vertical plane away from strap in towards the bumper. As the angle of deflection increases then the minor component of force in towards bumper increases.

Would your bumper/roo bar arrangement be capable of lifting the front end of the disco by using a hi lift jack? If yes then I can not see a problem with the bumper. If no, then should that bumper be on your vehicle?

Possibly I'm not sure...have never tried but it is a smart bar!
its an ADR compliant bullbar brendan I see no reason why it shouldn't be on the vehicle even if a hi lift wont lift it....not eveyone is confident to use a hi lift and not everyone carrys one.

just out of interest where are you suggesting I put the jate rings?

for anyone that doesn't know what the bar looks like

Well I couldn't really answer that unless I was in the situation but I bet we would find away But remember I never said I didn't have recovery points in the front I just said someone suggested not to use them as they looked thin! if push came to shove I would bridle off the two to spread the load and use them
This has happened in Gembrook on a trip I wasnt on but freinds of mine were with a D2 with no recovery points.

They destroyed the front bumper and tiedowns trying to extract it from what it slipped slowly into due to not being able to get traction on the shinny wet rocks on AT tyres.

They ended up wrapping a tree trunk protector around the chassis rails and using that as a bridle to connect the snatchy to and pulled it out.

That D2 now has a bull bar and adaquate recovery points.

There was not a scratch on the vehicle other than what was caused by the recovery.

Sooooooooo....

Have you thought of making a bridle type set up that can be hooked on somewhere under the car, Ive seen photo's on here somewhere of a cable type one on a D1 with standard front bar.

i think its the bar that gets in the way to be honest but I would always bridle if I had to recovery points on the front anyway or somewhere to attach as its less stress on the chassi
That would be cheap and strong and wouldnt interfere with anything else.

You could also get another plate welded up against the one you have to make it a bit beefier but this also depends on design etc weather that is possible

Phil did look at them and the way they were made we are not sure this is possible, I did how ever contact the guy I brought them off to let him know he said he might maje some longer ones to trial....he never got back to me


I dpont like hookjing up to Jate rings that are bolted to the bull bar, they are normally only rated for a straight pull to about 500 to 600kgs and even with 2 of them a snatch recovery will more than likely exceed that.

Hooks bolted on to the chassis or 10mm plate and reated bow shackles like what I have on mine (built into the bar mounts) are in my opinion better suited to snatch recoverys.

If were talking a normal line pull, not a snatch then near on anything would be adaquate as long as it is stronger than the tie down points.

the bars eyes would be stronger than tie downs for sure I reckon.

DB, those 2 straight bars with the holes in them which are well below the bottom of the bar, are they the recovery points your taling about, iff so, they are plenty long enough and depending on how think they are, from the second photo and not knowing any more than that I would think they would be plenty good enough as long as you didnt do too much (or to violent) sideways recovery.

I dont think that it would come close to hitting the bar with a 3m sling as a bridle

I have no idea what a smart bar or an ADR compliant bullbar is.

Having a look at the photo I would be surprised if your bumper would cause much proplem for front recovery.

The recovery point and front bumper on our Disco is like this




The front recovery points are bolted to chassis and welded to the bumper like this




Use two shackles with the bridle passed through loop in rope/strap spreads the load and reduces chance of a shackle flying.

I think there is confusion/misunderstanding over the term Jate ring. Jate rings are fasten to chassis legs where lash down eyes go. They are not mounted on bumpers and the strength is far in excess of 5-600 kg

In the photo below on the left is a lash down eye on the right is a JATE ring



The strength of the Jate ring depends on twice the shear strength of the 10 mm bolt. Assuming strength is on screwed section then strength is

Grade 8.8 7.5 tonnes
Grade 10.9 10.5 tonnes
Grade 12.9 12.5 tonnes

This is per Jate ring!

One problem with Jate rings is that unless you prep a bridle first then it can be a bit messy attaching the recovery gear when you are stuck in mud. One advantage for bumper recovery points!

no problem with the length of these it was the strength! the problem with the length is the recovery points in which I brought to use instead of these, they are what don't hang down far enough.

bendan I can't weld my'n the bullbar in plastic with a metal internal sketelon. so the recovery loops I have are all part of that metal skelton.......do you hsave pictures of where you are talking about the jate rings attaching to the chassi as I don't understand where you are talking about....not that it really matters as I would imagine tehy would havng down as far as the recovery points I already and no doubt again would caus the strap to interfer with the bar...the base of my bar does hang down quite low. I'am looking to chage the bar as soon as my money allows which will be a while as its not got a great approach angle

Now that is a good point because it shares the load through the bolts evenly.

where the which vehicle travels in the group is allways under the influence of Mr Murphy...... when things go pear shaped, it's a good bet the winch vehicle will either be unable to help or have to turn around!
