Why can't we use British harmonised Standard for shackles above 25 ton why we use RRC-271D standard

Hi Rama, There are a couple of standards that cover shackles, and I’m not sure which you are referring to. If it is EN 13889, this standard only covers grade 6 shackles up to 25 ton. The other standard is BS 3032:1958. This standard has been withdrawn but only went up to 12 ton. Currently we are using RR-C-271 rev. G, it was updated in 2016. This covers both alloy and carbon shackles from a capacity of 65 pounds to 350,000 pounds. We use this standard because it covers a wider range of products as well as sizes. It is a U.S Federal Standard. Let us know if you have any additional questions. Troy Raines Chain and Rigging Product Engineering Manager

I suppose round-pin shackles could be used for guy wires. Why can't we use stainless steel shackles ?

Good morning +Jester Mclarpet! To your question about stainless steel shackles - shackles are not rated in the same way as chain, plus shackles come under ASME B30.26, Rigging Hardware. In that standard there is no mention that a shackle has to have alloy properties or grade for lifting. So the use of stainless steel shackles is not prohibited as long as the shackle is made to the B30.26 standard. That would cover markings & design characteristics. Just to confirm, round pin shackles are not to be used for overhead lifting no matter what material they are made from. Hope this helps.Henry Brozyna

I dont mean to be mean about that comment. I'm new to this industry and for the past 7 weeks I've been watching videos in classrooms and this is pretty much the norm. Your company could do better with the same video but better audio to keep the peaiple watching from falling asleep. No offence just useful criticism

I think that we will delete this one completely so that people will find the newer one with the much better audio quality.
