Dear Friends,
I am looking for some information about Dee shackles. Is there any formula or thumb rule to calculate the SWL of the same? I have seen some different grades of Dee shackles. What are the differences between those grades?
Thanks in advance.

Dear Vijay,
You are right. In the market, there are many grades of D-shackles available. D-shackle grades are differentiated by IS standards, tolerance, etc. I am not sure as I don't have much exposure to D-shackle grades and the differences between those grades. I will discuss with some experts and provide you with the information as soon as I can.
Mr. Vijay, I hope we will get the solution from our active and senior members. Thanks for raising a technical query on our forum. Keep on asking. . .

Dear Vijay,
As per my knowledge, there is no such thumb rule to calculate the SWL of Dee Shackles. In all the Dee Shackles, SWL is clearly marked. Therefore, you can select the appropriate one based on this information.
Please refer to the attachment on Dee Shackles; it may be helpful to you. Let me know if you need any further assistance.
Dear Raghu,
Thank you for the posting. Keep up the good work.

Dear Dipil/Raghu,
Thank you for the post. I probably have the IS standard for this. I shall post the IS Standard Number by Tuesday. However, as correctly stated by Dipil, the SWL is marked on the shackle. Thank you, Dipil, for the ppt.

@ Raghu: Thanks for the follow-up.
@ Dipil: Thanks for the PPT.
@ Sudhir: I have IS 6132. Thanks for the reply.
Herewith, I have attached the SWL chart for the Dee shackle. However, how do I determine the grade of the Dee shackle?

Dear Vijay,
As per my understanding from IS 6132 chart (you shared), the grade must be available from the manufacturer. We need to ask them whenever we buy such items. I have never seen any grades written on Dee or Bow Shackles. Is the IS 6132 standard only two pages?
Dear Dipil,
Thanks for sharing the presentation with us.
Dear Sudhir,
If you have standards other than IS 6132, please share them with us.
Keep on going...

Dear Raghu,
My case is different. Suppose the subcontractor has purchased the items and is hiding the details, how can we find out the grades? He may choose to hide the information or simply not know the specifics. IS 6132 is not only two pages, but I am concerned that publishing it in a forum may lead to potential legal issues. If anyone needs it, I can send it via email.
Thank you.

Dear Vijay,
You’re exactly right. What we are doing in our projects whenever we offer a work to subcontractor in our contract its clearly states they need to submit the required documents at least 14 days prior to commence work its mandatory. My understanding in our work culture also they need to submit required documents if yes means they should submit test certificate for Dee Shackles. You can get all required information; it’s clearly addressed on all test certificates (see the attached extracted test certificate ).
Just ask them to submit test certificates if they don’t have it you can get it from manufacturer, but you should need Serial # and manufacturer details (I know it’s very easy to say but very hard to implement specially in our culture).
As long as the IS standard doesn’t have a copy right material no one can’t do anything not only IS standard’s its applicable for all materials.

Dear Raghu,
Here, we are also keeping test certificates, but they seem meaningless. The certificates are obtained from an approved person, likely a factory inspector, and only display the ID number and capacity of the Dee shackle. No other details can be found on them. As you mentioned, acquiring test certificates directly from the manufacturer is very challenging. The subcontractor is reluctant to disclose purchase details since they do not procure items from either the manufacturer or original sources. They simply invest some amount and obtain a test certificate from a qualified person.
Thank you.

Dear Vijay,
One of my seniors, whom I had worked with a very long time ago in India, recently obtained a competency certificate through an examination. Nowadays, he is issuing certificates for lifting accessories, etc., without following the recommendations provided by the manufacturers and government authorities. This lack of implementation of procedures by government authorities is concerning. In such cases, even if management asks us for test certificates issued by competent individuals, it seems futile.
Could you please share IS 6132 via email? Unfortunately, I accidentally deleted it myself by pressing Shift + Delete on my desktop.

Dear Anonymous,
Thank you for the information. I just want to know if "Form-10" is the same for the whole of India and if it differs for states according to State Factory Rules.
Thanks and stay safe,

Don't ask me to compromise on even a small thing for safety; this may ruin my attitude.
