So over the years i've had more than my fair share of D-Shackles being done up WAY too tight, and needing pliers or a screwdriver through the hole to undo them
And i've lost 2 or 3 D-Shackles because they weren't done up tight enough, and rattled off over a day of wheeling

So i had an idea, i took the bolt from the D-Shackle, and stretched a rubber O-Ring over it, and pushed it to the end
Use a reasonably sized O-Ring, it only needs to just squeeze on so you won't lose it

Then you put the D-Shackle back together, nip it up.. It'll never vibrate off, will stay firm.. And never be too tight to undo by hand

This probably isn't an original idea.. But damn i've never seen it before, and some of my friends think it's genius.

its better to not leave em on all the time as it wears and weakens the pins but industry came up with the solution

I could totally see myself losing that split pin

And those assholes, i thought i had a good idea here!

[alien]

yeah i wouldnt leave mine on - theyd rust up and be noisy =)

i have 2 shackles around the passenger's seat belt clip thingo on the floor, and 2 on the straps of the backpack that has my compressor hose and strap in it. each of the locations has a large one and a small one attached to it.

[jonno_racing]

i put mine round the grab bar on the pasinger side when we go wheeling...
other than that i leve them under the seat.

[lump_a_charcoal]

I had shackles once...

[matty87]

i dont use cheap Chinese yellow pins.

[MrRocky]

these days i only seem to need those when recovering another vehicle, and normally make the most of there recovery gear.(mine live under the seat)

How does paint colour make something cheap or chinese?

[303zuke]

Yellow Peril? I thought that was Japanese?

the manufacturers of rigging equipment have different ways of defining their product one of them is by the color of the pin. for example crosby use a red pin and van beest use a green pin (they are actually referred to as green pins in the industry just shows how well the color works).

as for the others we used a few cheap Chinese shackles on a job in Vietnam once and they failed big time and from memory they had yellow pins thats what that observation was based on. it is actually policy for most international and Australian companies to only use particular rigging manufactures we were however in a bind at the time and they were only used for a vessel tow and not lifting.

on that note dont buy cheap shackles they are just that and nasty.

You should be using bow shackles not D shackles.

Thats the other thing i forgot to mention.

[alien]

^^ my larger ones are bows, my small ones are d's... d's are the only ones that fit through "stock vehicle" recovery holes =/ i have to carry and use them on occasion as theres no other option, but its only in a tow situation, never a snatch.

[DarkHorse]

In theatre we use cable ties through the hole in the pin and then through the body - stops the pin turning.

Great for a show that stays put for months, not so convenient for doing every time you go wheeling.

Bit of antisieze and a welding rod. Use the welding rod thru the pin hole, around the shank and around itself. Mariners have been doing this since before jesus was a baby.

as long as they are rated and don't exceed there rating there is no problem.

Blackwoods source Chinese Shackles that have both Yellow and Green pins

you would think so. this however is not the case as alot of places are never audited and as such a rating means nothing.

also on the d vs bow they seam much the same but d shackles are really subject to side loading when used for snatches etc and are not designed for this. bow shackles are much better but you need a bigger one to meet the same load rating.

Im not saying that all chinese stuff is rubbish im kinda saying be carful because iv seen the aftermarth of snatch straps letting go and that was bad enough without a shackle attached and iv seen the aftermarth of these shackles failing at well under what they should have and if someone had been in the way it would have been a mess.

The problem with some chinese shackles is the amount of power outages that they get.
During production, if they lose power, it can compromise the quality, but there is no way of knowing for sure if it has been.

We deal with Chinese Factories daily, power shedding isnt something that jsut happens, people know and plan around it.

Like anything made anywhere, if the plant holds the correct certificates applicable to the manufacture of their goods and 3rd party approved and audited QC controls, chances are the product will be ok, who flung dung cheap shit can be made anywhere by anyone in any country

I've never understood the difference between a bow, and a d shackle
I think i refer to them as the same thing?

My 2 of the back look like this, 16mm bolt.. Most 4x4 places sell 'em rated for 3.5T you can also buy the 4.5T 19mm version


My one on the front (That i use alot more often, i have a Hayman Reece reciever on the back, so i use the pin)
Its rated for 6T! And its huge! Looks roughly the same shape.. But a good 50% larger than the other ones

D shackles yes?

[royce]

thats a bow shackle

So i've been lied to my entire life, even by google.

Is it perhaps a NSW thing to call it a D? Because noone i know calls it a bow.. Hell it even said "D Shackle" on the reciept!
AND on the image link i just posted

Why is life so cruel

[shep]

the one on the right is a 3.5 ton rated bow shackle and the other is a 4 3/4 ton
rated D shackle.

the difference in rating is due to the larger hoop even tho it lowers the effect of side loading it has a lower breaking strain. they are also easier on webbing as the webbing can lie flatter in them than a d shackle.

also as a piece of info for you all. Most might i iterate most d and bow shackles have a safety factor of 6 on them that means a 3 tonne rated shackle has a break load of 18 tonne

(you can not be sure of the sf of a shackle without actually looking at the specs on it tho)
