Why do 90% or more of people, even those that should know better, calls them clevis?! It drives me crazy,, but I don't correct them, but just go out of my way to use the proper terminolgy as often as I can. Shackles, not a clevis.

This is great info, the clarity and conciseness is appreciated. It's also good to know what is appropriate by US standards, because that's going to keep us safe and reduce the chances of successful lawsuits should anything bad happen. OSHA is a concern from fines of course, but more importantly if someone gets hurt and you're intentionally doing things wrong, pretty much it opens you up to suits that your insurance doesn't cover and that could be found to be criminal. To those saying "it's just the way we do it", I've only seen 3 ways shackles get locked up. One is somebody cranks them down like they're torquing down the ball on a hitch. It just has to be snug. Second, and most common, is somebody shock loads the system and you go WAY over working load. If you're using heavy lifting equipment, heavy cables, and light hardware, that's easy to do. If the crane is way heavier list than the load, consider bumping up the hardware to be 2x+ heavier than what's required for the load. Third is obvious, someone lets a fixed setup rust. I grew up with rigging a daily part of the business, and in 50+ years of operation we never had to cut a shackle off, and we never ran them loose. Use the right gear, use the right procedures, train your crew.

I deal in sea containers. I delivered a sale box to a gentleman once he picked the m/t 40ft standard box off the chassis with a 25 ft a 30 ft and 2 20 ft straps with a shackle at each corner. Oh. To connect everything he ran a log chain thru all strap eyes and hooked it to a 5 ton Galion crane. He got it lifted. I got the trailer out from under it. But that was the strangest rigging job I've ever seen.

The only thing I'm not comfortable with is it looks a bit half ass maybe to my customer, while I'm rigging it all up, a single 4 point, dedicated to container lifts, with a central load ring, wire rope bridle arrangement would just look better, like I seen before and used , when my customer had one and the container rigged when I showed up. Without Googling it, I'm thinking 4 to 6 hundred bucks for the setup, the rest of the time it'd be dead weight and in the way, whereas my slings combo are used all the time in various configurations.

@LiftingandRigging
@LiftingandRigging 2 жыл бұрын
You are correct, galvanizing is a process of coating the metal. It is best to check with the individual manufacturer to find out what base metal they use for their shackle. You pose an interesting question on the difference between a shackle and clevis. A Farm and Utility clevis is not used for overhead lifting. Farm and Utility Clevises are often used for towing applications. However, the terms clevis and shackle are often thrown around interchangeably in the world of lifting and rigging. No matter what you call it, shackle or clevis, it is best to pay attention to the WLL and follow the best practices discussed in this video. Thanks for watching!

If you have any angle in your sling, then the bow should be used as the sling collector. If you are connecting a shackle to your hook and you have multiple sling legs, then the bow should be collecting your slings with the pin facing up. Always make sure your pins are tight before you lift.

There are a whole pile of points that would be very diferent outside the US. Most of the world outside the US has standards harmonised with european standards. 1/ we generally refeer to "bow shackles" and "D shackles" 2/ we pretty much use screw pin shackles unless it will be permanently fixed or semi-permanent. We never use lose pin shackles for anything. I would not tie my dog up with one. 3/ screw pin shackles should not be tightened, because they are prone to getting jamed under load. The pin can and in some situations should be "moused", that is secured with string, wire cabe tie or such if there is any risk that it may come undone. 4/ outside the US it is a "split pin", because that is what it is. A cotter pin is something completely different. 5/Here, I have never seen a rated lifting shackle that is not galvanised, alloy steel.. 6/ We don't use carbon steel shackles. I have never seen a stainless rated lifting shackle either in person or in a catalogue. 7/ we do not tend to derate shackles from their markings, however, bow shackles are generally rated lower than the same size D shackle. Like so many other things, the US does this different to the rest of the world. . just as a matter of interest what is the minimum safety factor applied to shackles in the US. Here it is legeslated as 4:1 minimum, but most reputable manufacturers far exceed that, often publishing 6:1 or 8:1.
@LiftingandRigging
@LiftingandRigging Жыл бұрын
Lots of great points here! The majority of these translate to US standards as well, with the exception of a couple. To your 3rd point, that screw pins are not to be tightened all the way, as they may get jammed. Jammed or not, a screw pin must be fully tightened according to manufacturer recommendations. If needed, a tool can be used to un-jam them. Outside of the US, pretty much everyone refers to a cotter as a split pin, agreed. There are a lot of linguistic differences in the lifting industry as you move from country to country, and even regionally here in the US. Most shackles that are manufactured in the US by reputable manufacturers are developed to meet US and European standards, but it is always important to check that they are still in compliance with all local regulations. The minimum safety factor in the US is a 5:1 D/d ratio. Great points! Love to hear perspectives from those in the lifting industry across the globe.

@@LiftingandRigging All good riggers back the screw pin off by a quarter turn, from fully tight. Beginners learn this lesson pretty early on. It’s just good working procedure. The reason Crosby and other manufacturer don’t say to do this is because their attorneys (who know nothing about rigging or good working practices) forbid them to say it in the official literature, for liability reasons. It’s just one of those things you will never read in the manual but it’s just passed from tradesman to tradesman, year after year.

@@psidvicious I agree with you that this is passed from tradesman to tradesman, and I understand the reasoning behind why it is done. Unfortunately, though, OSHA does not care about any of that. OSHA states that we must abide by the manufacturer's requirements for use. Even if the reasoning is coming from an attorney, this is because it has been determined that even if unlikely, there is some danger involved in backing off a pin. If an accident were to occur, all OSHA would care about was that the manufacturer's recommendations were not followed.

@@LiftingandRigging That’s because OSHA and Crosby et al. are in the same boat. Their attorneys have told them, because of the exponentially remote liability issue, don’t say that, say this. That way we’re covered. [Especially] OSHA would never say, “Yea, I know what the manual says, but I’m telling you it’s alright.” Never in a million years. If you are properly verifying your rigging after each pick, you will never have a problem, backing the pin off a quarter turn, from tight. It takes about 6 or 7 FULL turns to completely unscrew a shackle pin anyway. I would challenge anyone to show causal effect evidence that this practice has ever caused a failure. That’s why tradesman continue to pass this practice on to the next generation. We know it’s safe AND it’s good working practice. You’re just not allowed to write it down or say it out loud.

@LiftingandRigging
@LiftingandRigging Ай бұрын
This was a very common practice in the past and is often knowledge that is passed down from older riggers to younger riggers, but it is now considered an unsafe practice, and here is why. Yes, the shackle may tighten down more when you lift; that is why there is a hole in the pin. A tool can be used to pop it loose. When you back off the pin you leave a small gap. If the load shifts to one side of the shackle while being lifted you run the risk of widening the spread of the shackle. Now the pin no longer fits the way it was designed to, the shackle body has been compromised, and the shackle needs to be removed from service. It is no longer safe for use. There is also a slight risk that the shackle can loosen more, if not hand-tight when the initial load is lifted off the ground. ASME B30.26 states that the shackle pin needs to be hand-tight and we need to comply with ASME standards and the manufacturer's recommendations for use.

The reason SWL is no longer used is that it implies you might be able to exceed this limit. Working Load Limit tells you that you shall not exceed the weight specified on the shackle.

“Alloy steel shackle”? Steel is an alloy, so what is alloy steel?
@LiftingandRigging
@LiftingandRigging 6 күн бұрын
The majority of shackles are made from two different types of steel. Alloy Steel and Carbon Steel. Alloy Shackles are made from steel that contains an "alloy" component, this means mixing other metals with iron and carbon. I'm not a metallurgist, so unfortunately I can't break down for you what that mix is to create alloy steel. Carbon Steel is made from a mix of carbon and iron without adding the alloy component. Alloy steel is stronger than carbon steel, so you can have a smaller-sized shackle with the equivalent WLL of a larger-sized carbon steel shackle. You also see this in chain. If you are using a chain for lifting it must contain an alloy component, either grade-80, grade-100, or grade-120. Lower-grade chains are made from carbon steel and can be used for things like tie-down applications but cannot be used for an overhead lift. This is because the alloy component will allow the chain to stretch before breaking if overloaded. Carbon steel will not stretch as much as alloy steel.

What crap, anyone who uses bolt shackles with a cotter pin for anything other than a permanent or semi-permanent situation or for a lift with high vibration doesn't know what he's talking about. Same for tightening the pin on a screw shackle, its common practice to back the pin off half a turn, otherwise it will often bind up and you might need a tool to take apart your rigging, wasting time, and depending on how your rigging is set up it might be a pain in the neck. Anyone who goes around and tightens the pin for repetitive lifts is a greenhorn, the pin will usually only start to back out if the load is picked up and set down multiple times, not even if there is a lot of wind or vibration, there is tto much friction to budge the pin while it is loaded. A shackle pin could back off if for whatever reason the load is being dragged or you are using come alongs (lever blocks) or winches, etc. and the load on a shackle is going from tight to slack multiple times. Real world experience.

It is not condoned by shackle manufacturers to ever back off a pin. This is an unsafe practice. The pin always must be fully tightened, even if that means using a tool to loosen it after a lift. It may in fact be inconvenient and add extra time, but should the pin loosen and an accident occur you may find yourself in some extra trouble with OSHA.

Overall safety is a combination of every aspect of a job. Yes we all know shackle manufacturers say to tighten shackle pins. For liability reasons, it is easiest for them to go that route. Ok, understandable. Is it unsafe to back off a pin an 1/8 or 1/4 turn? Is it safe to wrench down shackle pins each use? Depends on the job and who is doing the work. My point is, there is no perfect world, especially when work needs to happen. Also, manufacturers usually do their best to protect themselves. Of course Mazzella can't go around telling the public to disregard manufacturer guidelines. Theoretical work and actual work are different things. A rigger should be able to safely rig a load, tighten down shackle pins wrench-tight, set the load and remove the rigging. However, working efficiently is always a good thing to promote safety. More time spent on the job is more time a worker can get hurt. For a simple lift and set, there is zero concern the shackle pins will come loose. Rigging disconnect can become much more difficult when the riggers have to reach with tools to undo shackle pins. Potential for dropped objects increases exponentially. A rigger could die if he falls and is caught by his harness and is not recued promptly. Sure, riggers should be able to disconnect without dropping something but now you are comparing increased work and difficulty with the chance that a shackle pin will come loose and fall out. Crosby does publish pin shoulder gap allowable clearances. These gaps are allowable even after the pin is wrench tight. I have not seen similar information for other shackle manufacturers but then I haven't asked for it. I would surmise that Crosby had to show this information because generally speaking, their casting are pretty rough and their shackle pins do not always shoulder out on their shackle ears. On a small shackle you might have a 1/8" gap. This could equate to backing off a shackle pin a certain amount. I recently returned Crosby shackles for what I consider excessive shoulder gap. I typically now buy Van Beest Green Pin shackles, or if I can justity it - Skookum shackles. Anyway, some things to think about. There are times and places where shackle pins are tightened down or even moused. However, general lifting operations are not that place. Elliot is correct yet I understand what Mazzella and shackle manufactures have to say.

WTF You left out a Big No No, Never use a Shackle that says China or made in China, they’re usually painted red. Use only Crosby shackles made in USA 🇺🇸

This is often true but a common misconception as well. Only some shackles made in China should be used for overhead lifting. At the same time, many shackles made in China should not and cannot be used for overhead lifting. The best way to ensure your imported product is safe is to check the vetting process of your supplier as well as the shackle markings and identification. Many shackles made in China do not have a company trademark on them. This is required identification. "China" is not a company trademark. ALL shackle bodies MUST have the company name, WLL, and size forged or stamped on the shackle body if they are to be used for overhead lifting. If any of these requirements are missing, the shackle cannot be used for overhead lifting. Here is some more information on import vs. domestic rigging products. www.mazzellacompanies.com/learning-center/import-vs-domestic-rigging-products-how-to-choose-the-best/ And here is a downloadable shackle identification guide. resources.mazzellacompanies.com/shackle-markings-identification-guide -Ben

China is perfectly capable of making good quality shackles, IF you pay for them and you supervise them. Here is AU, where a lot of stuff is imported from all over the world, all lifting equipment must comply with and be marked according to local standards AND must be at least batch tested in country. Pretty much all lifting suppliers here have their own certified testing facilities. The enforcement is agressive and the fines are large. . In all countries including the US, you might be surrised how much gear is actually made in China, under brand names you know.

Highly annoying and wrong. Its called a d shackle because its shaped exactly like the letter D. A bow shackle is called a bow shackle because it looks like a bow and was formed by the blacksmith over a mold the same way bows were formed over a mold. Getting basic nomenclature wrong does nothing but cause confusion and can cause accidents when people are mis educated by self appointed internt loud mouths.

Hi. Self appointed loud mouth here. Bow shackle = Anchor Shackle. Different names. D shackle = Chain Shackle. Different names. Not sure where your complaint is. Feel free to pick up a shackle manufacturer catalogue if you're confused.

You are speaking to your audience like they are a bunch of first graders. Everything you say is hyper emphasized and all your words have upward inflections. This can be very off-putting to people and reduces the credibility of the speaker and the information being communicated. Not sure how aware you are of this, but this is how you come across to me. It looks like you are trying to produce a professional video, but your idea of professional comes across as patronizing in how much your are over simplifying your material. It is not my explicit intention to leave a negative comment, but I thought you might like to know at least how one viewer of your video interoperates your presentation.

Sorry, you aren't a fan. Many people who come to our channel are just starting their careers in the world of lifting and rigging and would like to know the basics. Just because you know everything doesn't mean everyone else does. Perhaps you might want to try some of our more advanced videos where we dive into a bit more complicated subjects. Not sure you are aware of this, but your intention, I believe, was to leave a negative comment... hence the negativity of your comment. I thought you might want to know how at least one creator of videos might interpret your comment. This is how you come across to me. -Ben
