G’day Rangerjack, Have the same setup but using 6mm kermantle, us old Navy guys must have the same ideas. Jake G’day Jake, must be the good old Navy training; if you don’t have the kit ……improvise 😄 |

G’day Haitch,
Kermantle ropes are high strength and very little stretch. The outercore is braided and basically a protective sheave and the inner is usually strands. This type of rope is usually used by climbers and rescuer work. For rescue it is either 11 or 13mm.
I found 6mm to be sufficient as its breaking strain is about 800kg., 6mm is compact for me and although its thinner I think will work well.
Dynemer rope at 6 or 8mm will also work well.
Jake

Thanks Jake. I think some 4x4 guys use similar sheathed stuff as winch rope. The sheath is basically a protective cover, they claim, preserving the load bearing fibres from rocks etc.Just didn't know its name. Is it the same stuff?

Looks good Keith. I would imagine some form of anti reverse or a means of safely jambing and releasing the rope would be desirable. Don't want to be anywhere near a 400kg outfit careening backwards down some gnarled slope. Either going up or lowering down.

If you want “compact” rope......you can always remove the sheath and the remaining Aramid is about 1/3 the diameter. We do this on our boat because it runs easier.......just one tip...do not nick it......it will break explosively.
3mm Dyneema has breaking strain of 1100kg
4mm 2000kg
6mm has a whopping 4000kg. I have this on both my winches. The one on my truck has hauled Urals up the steep ramps for 7 years. I also sling over tree limbs and have used it to lift heavy logs, batteries and the odd body.

All this talk about recovery gear has got me worried. I’d better start thinking about some kit myself. Only been stuck once!...on a beach in Tassie, and all it took was a tip from Lee to get it out without any help. l tell a lie, Bobsie got stuck in one of the Condamine river crossings in the Cambanoora Gorge. No recovery gear so I was it!...pushing like buggery from the back up to my ass in water, mud and rocks. I said to Bobsie “keep those revs up and give it a handful when I lift and push” Jesus wept! Bobsie shot out of there like a Polaris missile, up a steep muddy bank and didn’t stop for at least 50metres leaving me covered in water, mud and on my ass in the middle of the river. 😎    |

....."leaving me covered in water, mud and on my ass in the middle of the river. 😎 ".......
That is called 'payback' 😇
