RATED D SHACKLES

[achjimmy]

dayam @achjimmy
you must have had your "wheeties" this morning.

I am guessing, as a friend of mine is in Manufacturing, that the welds holding the chains on MUST comply with Australian Standard,

if you can video tape you doing that to your chain, and it breaks off, get a good Lawyer, we will be buying Jayco's from you man.... you would be owning that business.

your van stationary weights "X" amount
when travelling, multiply that by the inertia and kinetic energy, and you would be surprised at the weight behind it now.......
having something that is capable of holding X 1.5 the weight of it holding it to your car is not such a drama after all

sorry, I don't subscribe to the "just enough is good enough"
I would rather be "safe than sorry"

my $0.05 worth

Okay col I will do that but before I do. Let me know how many ticketed boilermaker welders Jayco or there chassis manufacturer employ in the manufacture of Chassis. Also as my background is aircraft maybe ask for the "release notes" on the material, chain and welding rods and there certification criteria for ensuring it meets your quoted standard? Chain being of a different tensile strength,what do they do, NDT (non destructive testing, xray or die penetrant) or do they do destructive and sample 1 in 20 sample welds on chassis?

maybe also ask how Stephen Galvins 17:56-2 passed through with incorrect chains welded on?? ;-)


Just joshing mate but if you really think welding half a link on to the chassis is going to hold better than an resonable quality shackle you will be disappointed.


The correct way this should be done, and I have only seen this on some earthmoving equipment trailers. Is to weld on a heavy plate over a large surface area to the drawbar, that extends down with a hole drilled through. Then attach the safety chains with hammer locks or shackles again (although this won't comply anymore I think) then the load is spread over a much greater area.

Agree that when other forces are applied, then the requirement is increased. My query, is if the rest of the components are shock load rated, not just the shackle.

As a note, from my 4wd experience, will only every use load rated shackles.

as I am not a coded welder, I cannot debate the structural integrity of the materials used, nor if Jayco are using Australian Complianced materials to start with, or if they infact use qualified welders.

there is a big difference between the cheap RHS that the Green Shed sells, and RHS supplied by BHP Steel - even I can see the quality difference there.

however, they are manufactured, they must pass certain criteria to be legal.

as for the wrong chains fitted - I think the QA/QC at Jayco need a new job, they obviously don't know what they are doing, for that to have passed.

(welding rods gave away you have not been aircrafting for awhile.... hahahahaha) they use this thing called a mig, with certain flux cored wire fed continuously as they weld.............


I would like to think that for my money, they don't have some Muppet without a brain "whacking" my van together.........

Col you read to much into it mate. I can never recall an aircraft being welded with stick mate, for that matter mig either. And if they did they wouldn't use flux core wire they would use solid with shielding gas. FYI the aircraft that were welded that I knew were tig welded. But most are fabricated with rivets etc and monoquue structure.

Yeah I like to think there not muppets too but then I do something on the van and that thought is challenged. But to be honest most things in a production environment today are built by people with no formal skills or trade. It is the process that defines the assembly and the quality.


Btw I can't weld for crap IMO especially as my eyes detioriate

 

[mfexpanda]

Found this in my blackwoods catalogue

 

[davemc]

kids sick did not get out today.. yes @mfexpanda if I need bigger ones not sure they fit in the towbar

 

[dagree]

Picked up a couple of 2T shackles this afternoon after all this talk and uncertainty!!!!!!
Did a trial fit when hooking up the van to drag it out and fit the rear bed end covers......AND!!!!!!!

With the new towbar the chains are now too short!!!!!!!!
Off to Martins Trailer Parts tomorrow to get some more chain and advise as to best/legal way to extend.

• Hammerlock and extend chain
• Grind off chain and get new ones welded on
• Grind off second link (Leaving one link welded to drawbar) and fit new length of chain with a hammerlock

Always something to sort out when making a minor change/upgrade :baby:

 

[mfexpanda]

What about a length of chain joined using a shackle

 

[dagree]

What about a length of chain joined using a shackle

The easiest option but in WA it's illegal to have more than one shackle per chain

 

[mfexpanda]

The easiest option but in WA it's illegal to have more than one shackle per chain

I didn't know that might be the same here .

 

[dagree]

Wouldn't surprise me @mfexpanda
Want to do it properly as don't want to take any chances with the boys in blue :mod:

 

[Angus]

So the hayman reese d shackles that are supplied with WDH do not comply as all that is stamped on them is the manufactures name?

 

[Four of us]

Now I'm really confused found this on www.myPolice.qld.gov.au/bundaberg

Bundaberg Road Policing Unit would like to advise that no rules have changed in relation to towing shackles. Additionally no related infringements have been issued.

This is an incorrect rumour currently being circulated via social media.

For more information on towing visit the Transport and Main Roads website.

Just found this media release from Queensland Police.

 

[davemc]

@Angus saw that just before and was just about to post.
Lucky as I found some 2t and they where not going to fit on the Disco

 

[Meanderthals]

My take on this:
1. Colour makes no difference as I have 2 pair of 2T rated shackles and one is green and the other is yellow.
2. Too many people confuse WLL (Weight Load Limit) with BLL (Break Load Limit).
3. If anyone wants to use non-rated shackles just because they fit then please don't have your accident near me. The cost for safe proper one's is minimal.
4. Although I'm attaching some info sheets that are specific to the NT they at least explain some of the terms used properly.
5. I'm using 2 Tonne rated ones that fit both the chains and the vehicle points, but if they didn't then I would use suitably rated Hammer Locks to do the link from the car to the shackle or the shackle to chain job.

Thanks @PhilD for the PDF its pretty clear there well hopefully I have it BLL vs WLL.
So the BLL for us has to be 3.2t or more
From this we need a 10mm 1T 6004kg BLL “S” or “6”
A lot less confusing will go out tom morrow and check the one I found today was walking past in bunnings looking for something else was twice the width almost.
I assume these from Bunnings will fit both car and be ok

[dagree]

Sorted the short chain issue this afternoon.....
Couple of hammerlocks and a couple of extra chain links added!

Our local Bunnings didn't have any rated ones when I was there but as I also wanted assorted other stuff to do my cyclone tie downs I went to a specialised rigging supplier where I was certain that I'd get quality gear.
