Safety Webinar: Proper Use of Shackles
HTML-код
- Опубликовано: 31 июл 2024
- Shackles are often used for rigging, whether you are lifting, tensioning, pulling or securing loads. This month, we will discuss how to properly identify, inspect and use shackles. We will define shackle types and configurations, take a look at shackle identification and markings, and review shackle inspection procedures and safe rigging practices.

Excellent training aid!!!!
The question is about GAC Flex (misspelled as GAK) it stand for Galvanized Aircraft Cable, which is the material used to make the sling. They look very much like poly roundslings but are built of a single strand of GAC (often 1/16") wrapped endlessly inside of a poly cover. GAC flex is quickly gaining market share in the entertainment industry due to the perceived improved performance in cut resistance and in high heat vs standard roundslings: as in keeping a load safely suspend longer in the event of a performance venue fire. GAC Flex is a fine choice for overhead lifting as long as WLL are adhered to like any other sling.
great lesson. thank you
Great video.thank you
Great video. Thanks
Thank you
What is the proper way to tighten a screw Pin on a shackle. I have a customer that is saying the top of the bolt is breaking it after using a wrench to tighten it. Should you only hand tighten a screw pin in a shackle?
I have a question,
Do you use the "mode factor" of 0.7 when using shackles ? Or is that only applicable when using slings and chains etc ?
Thanks in advance 👍
Good Video. Very useful for riggers and safety personnel .. thank you for sharing video.
Srinu, thank you for your kind words!
nice breakdowns
good job

We are so glad to hear your feedback. Thank you!
so helpfull
Hello Alberto, thank you for your kind feedback. Glad to hear that you found this resource helpful!
I have a question.
If i don't have 2 meter 5ton Swl wire sling, i can bring 15 shackles and connect them between each other to reach the 2 meter length which I need.
Its a safe or not safe, and there's a lifting standard for this practice........ If anybody have an answer so his reply will be appropriated
Technically you can as long as you account for the load angle factor, stay under capacity of shackles ofcourse
No tag lines installed by the crew which was a major no no. The footing (dunnage) wasnt secured which caused the load to slide and slip out. The strap was questionable but i feel it broke when the load was dropped causing more weight to be put on one side vs the other. Probably overloaded its capacity. Lastly them straps were on a bar with nothing preventing them from coming off. Why didnt they use a secure lifting lug with a shackle?
what are the three parts of a shackle? and how is a shackle measured to determine the size?
Hi William,
Ok, shackles used for lifting are screw pin shackles and nut, bolt & cotter shackles.
The screw pin shackle only has two pieces, the shackle body & the screw pin.
The nut, bolt & cotter shackle has four pieces - shackle body, the bolt or pin, nut & the cotter pin that keeps the nut from backing off.
The cotter in a nut, bolt & cotter shackle does not see any load.
All shackles, regardless of the manufacturer, must carry three markings on the shackle per ASME B30.26
:
1) Manufacturer's name or trademark
2) Size
3) Capacity
The size is what you’re looking for and that size will be the diameter of the body of the shackle, not the pin size.
Thanks for reaching out to us!

@@columbusmckinnon what factor of safety to be used sir?
good one for those that realy knows what it takes in lifting operations
Are your shackles equipted w/ a tonage rating? retired 537 p.f.
how to find crack on shackle..? what using method
Hello Elvin, magnetic particle inspection is the best method. It is non-destructive and cracks will be exposed - large as well as small.
- Henry Brozyna
Ok.thnks your information.
So the galvanized layer must be removed?
besides the mpi method are there other methods? because, there is someone giving the method in the way at the shackle. and he will find cracks through the sound of the sound produced, is that true right?
@@elvinrowanda8749 You do not have to remove the galvanized coating to do an inspection.
Abnormalities will be exposed with the plating in place.
As for other devices used to detect abnormalities, yes there are others.
As long as the method used does not damage the shackle, in any way, you can use it.
There are a number of non-destructive tests that can be used.

Why does everyone prefer the 7/8" size?
No special reason. It may be just a more popular size since it fits the majority of applications.
this helps most off roaders with winches to be safe.
