View Full Version : Snatch strap vs Snatch rope
What's the difference between the two?
The strap needs 5 to 10 hours recovery time. The rope doesn’t.
The strap can be used 10-12 times while the rope can be used 50 times.
Is this true?

As far as I know yes, but I may be wrong. That is the reason the rope is more expensive.

The fibre used in both is the same and comes from France so I don't think the recovery time would be that different. The key difference lies in the ropes ability to release trapped dirt while the strap often gets grains of sand or mud trapped between its fibres. The rope should last longer.
I would not be so specific on the number of pulls either because there are many forces of varying degree during each and every recovery. The simple rule of thumb is let the rope or strap settle for 24 hours and then measure it. If the rope hasn't returned to it specified length e.g 9 meters, it is damaged and should be used as pull strap and not for kinetic recoveries.
Here are some previous comments regarding this subject by Micheal Green, of Securetech/Spanset, who's also a member of this forum.
There is some more and I'll post it when I find it
no two recoveries are the same
each recovery is dependant on the following factors which will shorten or lengthen the kinetic recovery strap or ropes life span
(1)mass of the stuck vehicle
(2)mass of the tug vehicle
(3)speed of the tug vehicle
(4)how badly is the vehicle stuck
(5)stuck in mud is not the same as been stuck in sand
(6)how the kess / kerr is stored after recovery
(7)how many times in a 24 hour period the kess/kerr is used
a rope and strap is made out of the same material and therfore have the same or similar properties
(1)they will or must eventually wear out
(2)both require a recovery time period
how a kerr / kess works
(1)a kinetic recovery works because of the conversion of potential energy into kinetic energy
(2)imediate recovery ( the part that does the work)
(3)latent recovery ( the part that requires 12 to 24 hours to recover)
(4)these rules apply to both types of equipment
it can therefore be concluded that in principle there is no real difference between a strap and a rope and the rules for the strap applies to the rope and visa versa
difference between a kess and kerr
(1)kess is cheaper (kerr is about 2 or 3 times more expensive)
(2)kess has slightly less elongation 20% - 30% (kerr is about 30% - 40 %)
(3)kess packs into about 1/4 of the size of a kerr
in europe more ropes are used (as they have not had webbing available) while in australasia more kess are used (this is trend we follow here is south africa)
there is different elongation between a wet and dry strap/rope, there is also a different break strength between a wet and dry strap/rope
kess = kinetic energy snatch recovery strap
kerr = kinetic energy recovery rope

Makro sell a 16 ton 10m Spanset / Secure-tech kinetic snatch strap and rope. No other independant dealer except Safari Centre in Cape Town believes that there is demand / requirement for such an article. If you have no success in locating one please reply and we will assist further in trying to locate one or deliver one to you.
As far as using two snatch straps in parallel we would NOT recommend such for the following reasons:
1- They would have to be the exact same length
2- As these items are made made/woven no two batches are exactly the same ellongation
A snatch strap/rope is worn out by the following:
1- Used more than once in 24 hours
2- Incorrect storage
4- Incorrect material finishing
and many more
#1~ Spanset/Secure-Tech have launched a NEW snatch rope with a minimum break strength of 8000kg and 16000kg / 9m and 10m supplied in a heavy duty Cordura type storage bag
#2~ Snatch strap/rope must be manufactured from high tenacity high elongation polyamide yarn. One cannot tell the difference between a snatch rope/strap and tow/pull rope/strap by feel or appearance. If the strap/rope is not labelled for application then treat it as a pull/tow rope/strap, because one will do major vehicle damage if you use a pull tow as a kinetic snatch recovery as polyester elongates by only 5-8 % at break.
#3~ A snatch rope/strap needs to be no shorter than 9m metres because one needs to be able to obtain a speed of between 15 - 30 km/h to energise the strap/rope.Snatch straps/ropes are available in any length up to 100m. With a 6m strap/rope you will not be able to create enough energy for the strap/rope to work effectively. Remember a snatch strap/rope works for one reason only - the towing vehicles kinetic energy is converted into potential energy of the stretched rope/strap. The energy is transfered by the rope to the bogged vehicle.
#4~ The individual who secures his strap/rope temporarilly or permently around his/her bull is looking for short to long term trouble. As straps/ropes are manufactured from textile they degrade over time with continuos exposure to weather and UV. Kinetic ropes/straps are especially susceptible to rotting as they absorb moisture and will rot if kept wet. Store in a cool dry place out of direct sunlight.

Many thanx in advance
I thought I'd add this as well if anyone wants to question Micheal's knowledge:
24 years production experience and 15 years offroading...........
.........the manufacturers of the relative equipment who like myself would give information free of charge
So what would the suggestions be for a place like Mudslingers, where we can recover anything from 1 to 20 vehicles in a day. Some of them requires 2 or 3 pulls, per mudhole, and there's 3 mudholes. 20*1*3 = 60 ropes/straps
Would we therefore need between 20 and 60 snatchropes/straps ???
nu uh, you use only a few repeatedly... making sure you did your stretches beforehand in case that snatch breaks or a recovery point is ripped off (
It is mud after all... taai soos boomgom) and comes flying your way. :D
Maybe practise your Matrix type moves at home beforehand.
Normally on a trail we are between 5 and 8 vehicles with about 5 kinetic straps between us, never broken one... have broken recovery points before though.
I don't know if your average 4x4 guy can afford to buy a new snatch that often, stuffs expensive >:( >:( >:(
They should use their own straps/ropes ???

:) It is only good manners to have your own recovery gear if and when somebody need to recover you. It is like BOB says. The stuff is expensive. The other day I was asked to try and recover a LC with my winch. The winch cable broke and was replaced by Thys the owner of the LC within two days. I am more than willing to help a man like that each and every time. ;)

Jy het 'n Duke op jou bakkie? Wat was die lengte & diameter van die kabel op die winch wat gesnap het. Wat se grote winch het jy?
14-09-06, 04:36 AM
Duke 9500 met 35 m x 9.5 mm kabel. ( By Dune Off Road gekoop )
Die rede hoekom die kabel gebreek het. Ek het al 10 moeilike recoveries gedoen en die kabel het 'n paar platgedrukte plekke gehd.
Nog 'n rede is dat ek nie naby genoeg aan die LC kon kom om die kabel deur die katrol te sit nie. Die LC was amper uit toe die kabel breek. Ek weet tenminste dat my winch is sterk genoeg. :)
Myne aan die linker kant. Een van die moeilike recoveries.

Ja Willem, ek weet nie van jou nie maar ek haat eintlik die staal kabels. Moeilik om mee te werk, man moet altyd handskoene dra sodat die ding jou nie sny of steek nie, as die ding breek....kan potensieel groot skade en pyn aanrig.... :-[
Plasma tou is die "way to go". Sterker, ligter, dryf op water, kan gewoonlik meer tou op jou drom kry, maklik om mee te werk en as die seun breek...boef...val net grond toe.
Die foto van jou steek lyk dit vir my 'n lekker storie weg...moes julle gelyktydig winch?
14-09-06, 08:20 AM
:) Ek wens ek het nou oor die R2000.00 gehad vir 'n 30 m plasma tou. Dis net uit die 10 recoveries wat ek gedoen het was net een op my eie voertuig. As daai tou iets oorkom terwyl ek iemand anders help kan ek mos nie van hom verwag om die ding te vervang nie. So ek bly maar eers by staal.
Ja ons moes altwee gelyktydig trek. Johan en ek teen Eugene se Trooper :)
