And don't forget to taken them with you!

I made some milk-crate-max-tracks and the only time I've been out and needed them I'd left them at home. D'oh!

like them?

2m x1.8m of shade cloth folded into fours or 5's also works surprising ly well if you anchor it in a couple of places and better again if you screw a couple of short lenght of conduit to it.

Wonder if Dairy Farmers or Parmalat are equally impressed.

the force path tends to lift the front wheels out of the rut (like pulling a billy cart ), rather than trying to separate the chassis from the front suspension by driving the wheels further into the bog... which if you analyse it... is what happens with a JATE ring.

attachment to the axle is simple... the existing bolts had plenty of thread left so I simply bolted BIG 3mm thick steel washer in place with an extra nut. I slip an end of the sling over each washer BEFORE I get into the rough stuff. Can do same for the rear.

Then, you simply gather the wire sling in the middle and form a loop which you fix in place with a proper u-bolt wire clamp. Use the loop to secure a rated D shackle


The sling is held off the ground when not needed using a bungee cord. If you have a bull bar, all the better for tying it off. doesn't look as "tough" as a Jate but it's just as effective/ if not more so...


I found this great idea on the web when looking in frustration for ideas about recovery points on my P38 ...it's the "science" of it which appealed! see also
Technical Review of ADR for a full explanation

A 2.5M bridle strap seems much too short for your application, the angle formed by attaching the 2 eyes to the radius rods would be close to 90 degrees, which will Double the load on the sling, if you apply 2 to 3 tonnes of pull to your setup you will impart 4 to 6 tonnes of tension to your bridle sling, you should aim for an angle of less than 45 derees to avoid dangerous loads on the sling. Using a Bulldog clamp as you suggest makes the angle even worse with the possibility of the clamp being torn apart, bulldog clamps should only ever be used on Standing rigging (guy ropes) and never on slings, Regards Frank.

Thanks for all your replies, amazingly my jate rings arrived this morning, I got them posted to my work to make sure I got them.

I have not looked at where they go on the defender yet but was wondering if anyone new if the bolts holding the tie downs would be long enough and strong enough, as the jates did not come with bolts I will have to buy some, does anyone know what type I should get given they have to be strong and where in the Brisbane area I would get them?

thanks

Use 8.8 high tensile steel bolts - available from the Bolt shop on Evans Road Moorooka or Deshon Street Wooloongabba.
