Shackles

[louis fourie]

Watse groote shackle gebruik 'n mens vir recovery? Is die 3.25t shackle groot genoeg of moet 'n mens eerder die 4.75t shackle gebruik

[Thunder02]

Go heavy duty,never know when you have to pull a Landy

[CasKru]

Ek gebruik gewoonlik die grootste shackle wat die recovery punt toelaat.

[Stubs]

for the price diff go for the bigger ones, check out the ones we have on the 4x4 direct website.....

Neil, I tend to agree with you. The biggest shackle that I can lay my hands on is a 150t... Problem is they weigh 140kg each with a pin diameter of 108mm

Cassie, ek is besig om 'n bumper te ontwerp/bou vir my IFS, so ek is oop vir voorstelle. Ek is nog nie eers by my hardboard model nie - alles is nog net op papier

Stuart, I did and.... I rest my case

The right rigging practice if you snatch is your vehicle weight x 3.

Rudi, If I then use the 4.75t shackle and always use both recovery points I should be save?

Yes more than safe . the only problem with the smaller shackle is to fit some slings or recovery straps .

I have realized. I have 2X 3.25t shackles and it is difficult to get the kinetic strap in.

Are there any preference to any of the two shackles below (Pins differ)?

You'll have to upgrade your suspension for those boys

Yip, but I know Darrell

The top one...less tools to get it loose when it's tight (screwdriver or a Freestate vernier)

The bottom one needs 2 spanners

[pietpetoors]

Agree, top shackle. The bottom one will be nice for a more permanent fixture, that is why it has a split pin. For quickly on and off the first.

[Stubs]

hahaha, thanks louis !!!!! I will have stock in a week or so........quality takes time !!! LOL

Meet die grootte van die gat waar die shackle moet vaskom.
Maak seker die pin kan daar deurgaan. Baie ouens koop die groot shackle net om uit te vind die pin is te dik om deur die gat te gaan.
Indien jy jou eie hegtingspunte bou of jy bereid is om die gate groter te maak (indien te klein), gaan dan vir die grootste een.

Nee dis reg Pieter. Ek gaan 'n 32mm gat maak en dan 'n bush in sit met ID = 22mm, i.e. bush se wanddikte is dan 5mm

[pietpetoors]

Daai gaan kwaai werk
Die nuwe voorraad is tans by die poeierbedekkers en ek hoop om dit teen einde van die week of vroeg volgende week terug te kry.

Where can I find rated D-shackles in Cape Town?

[pietpetoors]

Not sure, try Safari Centre

Talking about ratings, I see on our supplier's rating sheet that the Safety Factor on our shackles is 6:1
The way I understand it, it means that it can actually take a load 6x more than what it is rated for, but they rate it at a 6th of the load to be on the safe side.

Ja, ek kan so iets onthou van my studente dae. Gewoonlik as lewens in gedrang kan kom gebruik hulle 'n veiligheids faktor van 6

Maak sin, ek koop die shackles by 'n plaaslike maatskapy wat hyskraan toerusting verkoop, dus moet dit dan juis ge"rate" wees omdat lewens in gevaar kan wees as dit breek.

I now have stock of rated bow shackles, check them at

I am sorted thanks

[WayneSchalk]

Bigger is better

[pietpetoors]

There is a white IFS in Langebaan which has almost that size shackles on the back. They just a little bit smaller, but almost that size.

I got one that I want to put on the detachable tow bar on my Vigo, just got to get that size square tube off-cut.

Just for the fun of it

[pietpetoors]

Cool idea, then you ready to recover a G6

That kind of shackle has a 5:1 or 6:1 Static Safety Factor or a Safe Working Load Ratio. They are designed for use in industry (cranes etc). The breaking point of the shackle is then 5x or 6x the working load indicated this provides some margin for error as well as the ability to withstand small shocks. They are not actually designed with dynamic loads in mind (that is sudden shocks) but rather gradual increases in load (when picking up a container for instance) hence the rating in kilograms or tonnes.

Shackles designed for dynamic loads (sudden shocks) are used more typically in the rope access area, they have a 10:1 Static Safety Factor and their breaking strain is given in kiloNewton (kN), which measures the force they can withstand.

Anyway, with that in mind, the kind of loads placed on these shackles even during recoveries using kinetic snatches do not exceed the Static Safety Factor and they are safe to use.

Thank you Nic, that is interesting to know.
