p3schwa Posted January 27, 2009 Share Posted January 27, 2009 Hi. We need to mark up our skackles. We have a dremel on the job, but it's not ideal.Any other great suggestions would be most welcome!!!!!! Mark Link to comment Share on other sites More sharing options...
ianl Posted January 27, 2009 Share Posted January 27, 2009 marking to indicate ownership or individual ID marking for inspection records? Link to comment Share on other sites More sharing options...
AndyJones Posted January 27, 2009 Share Posted January 27, 2009 Hello, DON'T use a Dremel! You need to be looking at some sort of surface marking. A logo/ID printed on paper and held in place with clear Heat shrink is the best option I have seen. Although arguments have been made that this doesn't allow inspection of the area underneath the marking.... Whatever solution you come up with there should be no writing or marking directly onto the shackle OR engraving. HTH AndyJones Link to comment Share on other sites More sharing options...
jonhole Posted January 27, 2009 Share Posted January 27, 2009 If it's just to indicate ownership, then a small cable tie should be fine? You can easily mark different weight loads via different coloured cable ties. Link to comment Share on other sites More sharing options...
Al Cain Posted January 27, 2009 Share Posted January 27, 2009 if your woried about not ebing able to inspect underneath the heatshrink, then another idea might be to make up little tags for them- say even lamiated pieces of paper, which are cable tied - loosely to the shackle. not ideal I know ( I mean having bits of shinny shinny haning in your rig etc) but it solves the 'non visable inspection problem I would have thought?! - note that this is mearly a random thought rather than someting I have tried. Most place I have worked - or work at use the method Andy Jones recommends - dymo label and heat shrink. However I can only echo his comments about not for love of anything technical, using the dremel! - think about what its doing to leave that mark - remiving that material will possible result in weaknessing of the whole shackle - something that makes me and most riggers, and I suspect most technicians with a small ammount of intelligance- leave nasty things in their boxers/y-fronts/thongs/girl boxers/granny knickers/you get the idea!

Seano Posted January 28, 2009 Share Posted January 28, 2009 If it's just to indicate ownership, then a small cable tie should be fine?Cable ties on shackles are a pain in the thumb. Especially if they're cut so as to leave a razor sharp pointy plastic triangle right where you don't want it. I must have lost a pint of blood to LSD/PRG's shackles over the years. Well, maybe not quite a pint; but very nearly an armful. You can easily mark different weight loads via different coloured cable ties.If a shackle doesn't already have its WLL clearly and permanently marked on it, it shouldn't be used for rigging anyway.

oli Posted January 28, 2009 Share Posted January 28, 2009 we used to use airfix paint, place a little dot on the shackle and pin in a certain colour for each year inspected. It also scrubs off fairly easily so that you don't end up with a polkadot shackle after a while Link to comment Share on other sites More sharing options...
jonhole Posted January 28, 2009 Share Posted January 28, 2009 If a shackle doesn't already have its WLL clearly and permanently marked on it, it shouldn't be used for rigging anyway.Indeed, but it's also a quick and easy reference point if they have been muddled up. I don't find many problems with them, as long as they are small, and cut right back. we used to use airfix paint, place a little dot on the shackle and pin in a certain colour for each year inspected.This is something else you could do with the different coloured cable ties, although I quite like the idea of using paint.

Chappie Posted January 28, 2009 Share Posted January 28, 2009 A set of small stamping pins works very well on shackles. You must be careful when stamping though to make sure the area is suitably supported and you don't place undue pressure on any part of the component. A Dremel or something similar can work very well on items that don't take well to stamping, such as painted or powder-coated surfaces, where the majority of the material removed is actually the coating. I usually only engrave items of a suitable size where any metal removed is negligible in terms of the overall size (or SWL) of the item. If you are in doubt, give a specialist rigging supplier a ring and talk it through with them. Or just ask the qualified engineer who comes to inspect your stock periodically.

Rexeltw Posted January 28, 2009 Share Posted January 28, 2009 We've been advised by Mr H&S that there can be no obstructions to vision on any rated steels or shackles. This bizarrely includes not pvc taping up the fray on steels where they are crimped! We now have had to present our shackles for test without the small cable ties we use to check retest dates or they get failed on sight! Not sure how this will affect people like Summit who have always painted their whole shackles or the fact that Crosby's come with the pin pre-painted. More dullness on the horizon I guess.

Chappie Posted January 28, 2009 Share Posted January 28, 2009 We now have had to present our shackles for test without the small cable ties we use to check retest dates or they get failed on sight!That seems a bit harsh. Can you get someone different to do the inspecting? Link to comment Share on other sites More sharing options...
Rexeltw Posted January 28, 2009 Share Posted January 28, 2009 To be fair they have to be removed anyway so its not a major bother. I'm sure all these rules stem from the days when people would wallpaper over a crack on a ladder to avoid having to throw it. Our rigging testers are fine about it but we do put a lot of work their way, it was more of a "you do know this is how its supposed to be " statement that people like to give to cover their arse. Still it could be worse. I have seen people stitching back together roundslings after they got caught in a motor with the FOC hotel sowing kit!

One piece of guidance that I was given was that it was ok to engrave the galvanising on the shackle as long as you didn't hit the metal underneath :D Sounds a bit tricky to me!

GRisdale Posted January 28, 2009 Share Posted January 28, 2009 This bizarrely includes not pvc taping up the fray on steels where they are crimped!Surely it would be otherwise difficult to check if the crimp was slipping (the dead end moving to inside the crimp). Unless I'm misunderstanding you... Gareth. Link to comment Share on other sites More sharing options...
Chappie Posted January 28, 2009 Share Posted January 28, 2009 I could see stamping being frowned upon quite severely given that it's altering the structure (albeit in a very minor way) of the metal.This was the method I was instructed to use on a training course at one of the larger rigging companies, so I have used it ever since. Also, any shackles I have ordered from rigging companies that I have asked to be marked with serial numbers have arrived stamped. I was also stamping and engraving this morning, whilst our 6 monthly inspection was taking place and the engineer had no problems with either of them.
