Good video. If you read the Crosby literature, you can side load a shackle and have your slings outside the 90 degree marks. As I recall, the shackle can support its full load capacity within the marks. Outside the marks it's reduced to 80 percent. In a side load it's reduced to 50 percent. For example, we have a forklift with a hole in the end of the fork. We use a 1" shackle through that hole to lift things with a chain or sling. The shackle is rated for 8.5 tons, but reduced to 4.25 tons for a side load, plenty for our application.
Great info. The only thing I would like to mention is the backing off of the pin. I took a course with Crosby and the rep said to never back the pin off. It was standard procedure where I worked to tighten the pin all the way then back it off a 1/4 turn. The reason folks did that is that is sometimes the pin is tough to get out after a lift. The Crosby rep said that there is a possibility that the threads of the pin could stretch more if the pin was not fully engaged. Also you run the risk of exposing your sling to the pin threads which could damage and, in a worse case scenario, cause your sling to totally fail during a lift. The shackle is engineered to have all threads fully engaged. Always fully tighten your pin. You can always use a wrench to loosen it after the lift is completed safely. Thanks again for the video!
Crosby provides a WLL reduction chart that allows you to side load any shackle up to 90* with up to a 50% decrease in capacity. Also if your sling angle is less than 120* if using two or more slings you can use the shackle at full capacity.
Great video bud!!! I have another idea for a video but it’ll be a pain. You can go over some of the different cables, left and right lay, over and under the drum

Very informative video! I had recently heard that shackle manufacturers are stating that the shackle warranty is only valid with the screw pin snugged up. Which could potentially be brought up in a legal situation if something were to go wrong with a pick. I know riggers have been loosening a quarter turn for forever. Any input on that? Thanks for the videos! Keep them coming!
12:32 Well yeah that's what I was wondering regarding your first point. I'm no crane operator but I watch a lot, & I help rigging a bit. Literally everything I've ever seen lifted that has lifting lugs is lifted like that with shackles & the pin always goes through the hole.
I think I know the answer, but I don’t have a set of shackles in front of me to experiment with - Is there a rule for shackle to shackle connection, orientation? Pin-pin, shackle-shackle, pin-shackle?...don’t wanna beat a dead horse here.
I use shackles and slings and straps and chains and stuff everyday operating a tow truck and it is definitely not repetitive back and forth motions certainly not long enough to try to back that screw out so I just snug it down hand tight and back it off a touch and I've never had one come out on its own
Great video. And yes I just Refreshed my Rigging Cert through the International Union of Carpenters and they say now we don't turn back shackle pins at all.
What does a Union Carpenter need a Rigging cert for? On a Union job site the Ironworkers are doing 90% of the rigging with Boilermakers doing their own also. This is the problem that most trades have with Carpenters, they want to be a jack of all trades and they end up a master of none.
It's all about physic's and common sense. Great explanation, thanks. I'd be willing to bet those shackles are rated for X amount but in actuality can handle a good bit more, but not a good idea to do so.

There is in effect a National law from OSHA that all who rig take and pass a basic rigging class and hand signals and keep both cards in their wallet. All States this applies.
Turk 317 Also a man lift and forklift telehander ( Lull) requires such. My buddy got nailed running a lull by OSHA big fine not having card. In NYS you need a license to run crane or arrested in handcuffed. Seriously. NCCCO and Crane Institute has OSHA approved classes all over.
I know some manufacturers allow full load at 45° angle, (greenpin for example) but normally a reduction of 30% or WLL x0.7 is required. You can actually side load a bow shackle though, the reduction factor just becomes 50% or WLL x0.5 Where I'm at we can't use this type of shackle for repeated lifts, a nut with some kind of locking is required, for that reason allone my company doesn't use them (which can be annoying because on some lifting points in the field you can't fit a bowshackle that requires a bolt..)
Hah, I'll be that guy. You said the shackle was designed to be within the 45-degree lines, and you counteract that by saying you "should" back it out even though manufacturer says to tighten all the way. The pin is supposed to be tightened all the way. If you don't have a bar, then smack the fucking shackle on something and it will loosen the pin. Or keep the spud bar on you buddy. If there's any reason you shouldn't do it, it's because of tests, so you should follow the "Best practice". Otherwise, stating that just sets other people up for failure. I don't believe a screw pin shackle will unscrew itself anyways, just stating this for ya.
you tighten the pin and leave it tight. every time you back it off and use it that way it will still be tight after use because you have stretched your shackle, and keep stretching it with each lift. if the pin does not reach the outside of the body when screwed in then it must be discarded as it it to stretched. the pin is the same as a collared eye bolt where the collar must meet the flat surface or it load the threaded part sideways, if you back off a pin slightly have a feel at how much the pin can rock left and right so it leaves a chance the pin can be spat out and i have personally seen this when i was a chain and rigging certification tech for years. those that taught you to back it off were taught badly themselves and keep handing down that bad information to the next generation. it is not just Crosby that say to leave the pin tight and to think that riggers wont take the advice of those that design make and test these things is beyond me. i have assisted in investigations into injuries and death involving shackles and have just dodged being seriously injured myself when going to check on lifting gear that someone had not looked after correctly. it was hanging only by the edge of what was left of the thread on the pin that was fully disengaged from from the threaded part of the shackle and sitting on the square edge of the stringer plate on a push trolley of a sliding gantry.. i have also had them explode in a testbed when not near their test limit let alone being anywhere near a break load. another really important note with shackles is NEVER swap pins between shackles ALWAYS use them as a matched set with original pin. i would see all the time where places had shackles form different ages and manufacturers and some had metric threads some had imperial and yes the pins will screw in but the holding force is way lower in the thread. another was old shackles with CWT marked on them (really old ones mostly) CWT means "Hundredweight" and i would see people with a 60CWT shackle used alongside 6.5tn ones thinking they are the same rating because they are near the same thickness and pin size. if the customer would not let me remove them i would remark them and i would show them the conversion which is remove the last number and divide the rest by 1/2 and you get a safe working load. so a 60CWT shackle you remove the 0 divide the 6 by 1/2 so 3tn was just under the actual lift rating (3048Kg)
I’d love to get your opinion on the rig we used to use for flying tall steel columns. I know you probably would never publicly approve of it but I bet in your head you would probably say “I like that!” It’s a bit complicated to try and explain. I’d have to draw you a picture and I don’t know how to send those on TH-cam comments. You may have even seen it. I’m in So. Fla so I don’t know if it’s just a regional technique or maybe everybody knows it. It never failed.
@1:57 I've ran across many situations where only the pin will fit thru the lifting lug..gotta use it upside down. Or else the shackle isn't strong enough to hold the weight. As experienced as you are I'm surprised you'd take such a strong stance
I have an argument with one of my riggers. He says It Is okey to attach two shakles on a master link then throw it to the hook. Obviously the shakles Will have sling holding the item as gravity pulls down and crane is pulling up.
Gary, I am glad you learned a little on this one. My main concern is...How are you doing? I know you had a few stents put in. Are you holding up ok? Thanks for watching! 🙂👍
Is it legal to join 2 shackles I had to rig up to a door on a steam generator and a a tiny 1T shackle was the only 1 that fit on the attachment point but my slings would not fit so I decided to join a bigger shackle
@@ToTheTopCrane you nailed it 👍👍👍 I was on a boat shrimping net hung down shackle head half an inch of play on pin both sides and now I know way what happened, happened I just learned thankyou and enjoy the weekend

Iam doing fine tks 4 asking. I do pull some times can u put the hook threw the shackle instead of the pin ive been doi g that ever since i can remember my dad did it tks gary
Since you are a truck/tractor puller, I don't know that it would make much difference. You are loading the shackle inline regardless of the direction of hook up.
What does a cream shackle look like? I don’t think I’ve ever touched one before. I have seen several different size carabiners before, but I wonder if this is completely different?
As you could see in my crane video, I did not have reading of any sort because of the type of thing I was lifting, however this would be extremely helpful for moving heavy your containers.
I really wish my big crane would’ve come with some rigging accessories. That’s pretty much the only draw back to it. However if you want some information about where to get the model comment about it on the crane video and I will post The info for you.
A crane shackle is similar in shape to a horseshoe. However it is made from rounded material and has a removable pin that closes the open end. The pin is threaded and screws in. Hopefully that was an adequate description. If not, let me know and try to give more detail. Thanks for tuning in! 🙂👍
my job is rigging. I agree that tips for the safety. i always follow the book.....thats my the best way.. .. rigging the one of the dangeous job. support 100% keep it up boss......
The only time I've seen shackles work loose is doing duty cycle type work- mostly wrecking ball and clam bucket work.. and we wired the shackle pins to make sure they didn't back off...
In those cases you should be using a shackle with a bolt and a castellated nut. We had the draglines connected to magnets with a shackle with a bolt. The material handlers also used one to hang the magnet.
This is a very good video. I'm 32 years crane operator. Local 487B Miami, with them for 17 years. Currently working in Israel, with Intel-Israel. I'm lifting 11.5 ton 50' beams. All day, I use 8.5 ton shackles on each end. With 2, 18 feet 8 ton " High Performance roundsling, hooked to 2, 10 foot 16 ton chains. I keep it long in order to stay within the 45 Degree angle. Also, from time to time I slide my roundslings so the I do not work with the same area. Yes, I keep my crew rigging with the screw in the hooks.
Very informative, makes sense, just never really thought about it. What about putting the shackle directly on the load like with ears, I assume pin in the ear is correct?
The only reason to turn the shackle pin up is if you do have a endless in bottom (towards the load) because when it tightens up on the load it may roll the pin. Yes you can turn a shackle 90degrees (side ways) it’s called a 90 degree offset and the shackle is good for 50% capacity. Why would you though? No idea... Just like “never saddle a dead horse” well why is that? It has nothing to do with the saddle of the clamp on the dead end, it has everything to do with not putting the bolt-end of the clamp on the live end. So basically it’s to keep your ass from crimping the live end of the cable. “fun fact”
Cool Beans. 1. It is confusing to say that just because you take a different angle to lift an object that it increases in weight. I think much better would be to State the actual physics where the force applied on the shackle would increase if the angle-of-pull becomes too parallel to the ground. In a former life I looked to become a rigor working with cranes. My studying off an online Union manual was to state to keep the angle of pull close to 45° to the direction of oull. My affliction with acrophobia pretty much kapashed that dream. 2. While it may take 7 full turns for the pin to unscrew, may you tell me at which turn of the screw that the shackle is no longer rated for 13 tons? One turn, Twontrina, Three...??? Seems to me that a clevis would be a better choice than a pin. The clevis can freely rotate without unscrewing. The pin that goes through the whole of the pen can be pulled out with a finger no tools required faster than rotating a pen 7 turns. But this is just me: what do I know...
Bit late to the game here, but I found another video showing strain tests on shackles, which I think illustrates why you don't load from the sides of the shackle. Hope this helps someone: th-cam.com/video/66BXmM_JuBI/w-d-xo.html
Jimmy, are you going to cover estimating center of load and center of gravity for irregular pieces? For a few decades, I've been putting anti-seize on pin threads, and backing the pin off a little for most lifts. Never had a pin back out even a little. This video was awesome instruction for using shackles! Thanks.
i dont like using anti-seize on any rigging, just bacause it can get onto the strops. And atleast where i work any grease, oil, paint etc. on strops means we dont use it. Norwegian law.
@@mattis537 Makes sense. Grease, paint and solvents destroy synthetic straps. I started using anti-seize on screw pins when I was working on the Pacific coast. Even galvanized pins rusted in salt water after a while. Anti-seize reduced that problem. But, we did have to be careful not to get any lubricants on straps
would you think a 1" Crosby shackle is over kill for use with my jeep and 10,000 lb winch? I bought one encase I needed to use my snatch block on a heaver load.
Yehmen ! I worked “with” many riggers as they were the ones who would move the equipment that I was responsible for aboard naval vessels (surface craft & submarines). I often say, I would enjoy being a rigger if I wasn’t a marine machinery mechanic for PHNSY shop 38 (retired after 35yrs). Needless to say I have many stories to share (both ah ha’s & holy crap).
If straps get a twist in them? Is it a major safety concern or just hard on them with unwanted wear? Thanks for bringing common sense back to the masses!😎
It depends on how much twist. Technically it should all be twist free. However, if there's a few gentle twists that aren't rubbing on something or causing damage to the strap, I generally don't get too concerned. Thanks for watching! 🙂👍
@@ToTheTopCrane I wondered if they got a single twist if it was grounds to start whole rigging over. Sounds like it just depends on situation. Thanks for answering all my questions!
@@ToTheTopCrane I truly enjoy them and they just continue to get better. Hope you were able to rest some today before heading back to rat race tomorrow?!?!🏗
Also a lot of guys look at a sling and see basket configuration rating. But for true basket configuration rating you would need to use a spreaderbeam. Even 1° angle is not a true basket
Great video, great instruction. Excellent representation and comments on "real world" situations and how the theoretical is not always the challenge for practitioners. Not sure how you can teach common sense, though, and that is the problem. Effective learnign and knowledge starts with facts first and then the application of the factual knowledge to the real world................not the other way around. In other words, "book smart" first and then practical experience= optimal and safe operator. He implied this when he said you have to "know where to draw the line" and that only comes with the perspective of factual knowledge combined with practical experience. If you don't have the formal, book knowledge of the physics involved in this, you have "monkey see, monkey do" learning and some of the monkeys do things where only luck or some other variable saves them. Unfortunately, their luck runs out with enough repetition of the faulted procedure.
I only drive a 12k telescopic forklift with a 60' vertical and 47' horizontal reach but have always tightened the pin fully and then back off half a turn. Our work it quick paced and very repetitive and never involves any lengthy picks or overnight slinging. Just found your channel and digging your knowledge ;)
Hey Jimmy! In terms of tightening the pin of a shackle, what’s the length you would consider “awhile” when tightening it all the way. What if something will be up for like 24 hours is that long enough to consider tightening it down plus using something to lock the pin down?
Kyle - if you look at the tag (should be there) on the strap/sling, you’ll see the type of config you’re talking about. But when you look at the load capacity in that config, it drops drastically. I don’t know if -50% is a constant, but it’s way down. Beyond 45°, you’re past the point of gravitational advantage. Past halfway up and halfway down.
Lets say you have a large steel plate thats laying flat. You can blow a hole in it and hook up the shackle. Then to pick it up you would have your sling in one end of the shackle bow which would be well below the 45' mark
Ha! You did do it! Thanks for the effort. Even saw you sweating on that one! I know you said in your 1st video, this wasn’t going to be a ‘how to’ channel but rigging and cranes go hand in hand. I think it’s important to get proper and correct info out there on rigging. How many times has this happened to you: You’re in the seat, working in the blind. Signal man walks over to the edge of the deck and gives you the ‘get high’ sign. You cable up and as soon as you see the load you say OMG! Also, except with structural iron workers, what’s the first tool they go for to loosen up a shackle pin?? THE HAMMER 😖 and they miss a few times and dick-up your sling. Right? I know you’ve seen it. Back the shackle pin off a 1/4 turn. Great vid and info. Thanks again 👍
You asked for it. So, I made the video for ya. It was HOT in the ole crane building. Glad I didn't spend anymore time in there than I did. Thanks for watching! 🙂👍
What if you have a shackle and it’s to a tow receiver where it’s fixed solid and your pulling sideways like out of a ditch on the 45° angle. Is that fine or does a shackle need equal load on both sides?
It probably should be loaded in the center of the shackle. But, it's not being used for lifting. So, you will have to use your own judgment. Thanks for watching! 🙂👍
Novice question. Why don't I see rigging with chains as much as nylon straps? This is heavy machinery and equipment... not trees, so I thought you'd demonstrate with chains.
Great explanation video and said with common sense and safety in mind too!

Some of his info is off. But he is pretty competent, but not a definitive authority by any means
70% reduction at 45° and 50% reduction of capacity outside the 45° marks

Believe me, you can accidentally unscrew a shackle tim very quickly, especially while using continuous loop straps.
Ironworkers will get pissed if you send them a shackle fully tightened

you tighten the pin and leave it tight. every time you back it off and use it that way it will still be tight after use because you have stretched your shackle, and keep stretching it with each lift. if the pin does not reach the outside of the body when screwed in then it must be discarded as it it to stretched. the pin is the same as a collared eye bolt where the collar must meet the flat surface or it load the threaded part sideways, if you back off a pin slightly have a feel at how much the pin can rock left and right so it leaves a chance the pin can be spat out and i have personally seen this when i was a chain and rigging certification tech for years. those that taught you to back it off were taught badly themselves and keep handing down that bad information to the next generation. it is not just Crosby that say to leave the pin tight and to think that riggers wont take the advice of those that design make and test these things is beyond me. i have assisted in investigations into injuries and death involving shackles and have just dodged being seriously injured myself when going to check on lifting gear that someone had not looked after correctly. it was hanging only by the edge of what was left of the thread on the pin that was fully disengaged from from the threaded part of the shackle and sitting on the square edge of the stringer plate on a push trolley of a sliding gantry.. i have also had them explode in a testbed when not near their test limit let alone being anywhere near a break load. another really important note with shackles is NEVER swap pins between shackles ALWAYS use them as a matched set with original pin. i would see all the time where places had shackles form different ages and manufacturers and some had metric threads some had imperial and yes the pins will screw in but the holding force is way lower in the thread. another was old shackles with CWT marked on them (really old ones mostly) CWT means "Hundredweight" and i would see people with a 60CWT shackle used alongside 6.5tn ones thinking they are the same rating because they are near the same thickness and pin size. if the customer would not let me remove them i would remark them and i would show them the conversion which is remove the last number and divide the rest by 1/2 and you get a safe working load. so a 60CWT shackle you remove the 0 divide the 6 by 1/2 so 3tn was just under the actual lift rating (3048Kg)
I’d love to get your opinion on the rig we used to use for flying tall steel columns. I know you probably would never publicly approve of it but I bet in your head you would probably say “I like that!” It’s a bit complicated to try and explain. I’d have to draw you a picture and I don’t know how to send those on TH-cam comments. You may have even seen it. I’m in So. Fla so I don’t know if it’s just a regional technique or maybe everybody knows it. It never failed.
You can reach me by email. tothetopcrane@gmail.com
Great, I emailed you a sketch.
I’ve heard people call it a ‘Manhattan rig’ before but I couldn’t say if that’s where it came from.
@1:57 I've ran across many situations where only the pin will fit thru the lifting lug..gotta use it upside down. Or else the shackle isn't strong enough to hold the weight. As experienced as you are I'm surprised you'd take such a strong stance
I have an argument with one of my riggers. He says It Is okey to attach two shakles on a master link then throw it to the hook. Obviously the shakles Will have sling holding the item as gravity pulls down and crane is pulling up.
Learned alot on that video good one!
Gary, I am glad you learned a little on this one. My main concern is...How are you doing? I know you had a few stents put in. Are you holding up ok? Thanks for watching! 🙂👍
Is it legal to join 2 shackles
I had to rig up to a door on a steam generator and a a tiny 1T shackle was the only 1 that fit on the attachment point but my slings would not fit so I decided to join a bigger shackle
NEVER back a shackle off its old talk which is now advised not to so tighten it up by hand only
B30.26 specifies NOT to back the pin off
Isn't the reason for seating the pin all the way to keep the legs from spreading?
Great video not boring and we'll explained. and now I know why we pulled the threads on one of them shackles years ago.
Smaller bell shackle
Must have been side loading it? Thanks for the compliment and for watching! 🙂👍
@@ToTheTopCrane you nailed it 👍👍👍
I was on a boat shrimping net hung down shackle head half an inch of play on pin both sides and now I know way what happened, happened I just learned thankyou and enjoy the weekend
@@joshwelner1951, hope you enjoy your weekend as well! 🙂
You did a great job explaining it. I sub here about a week ago. Keep up the great videos
+Kenny Mysak, thank you! I try to go as in depth as I can without confusing people. Thanks for checking out and subscribing to my channel, also, thanks for watching! 🙂👍
What about using two shackles together in line?
The right way is you tighten the pin all the way back it off
Very nice
Great information Jimmy, I have always wanted to know more about shackles
+Brandon, thank you. If there's ever anything you want me to talk about, let me know. I'll try to get it in there. Thanks for watching! 🙂👍
50% on a side load manufacturer rating
Very good information Jimmy. Anyone that side pull on a shackle is playing Russian roulette
+John Warren, thank you! That is very true on the side pulling a shackle. That is a terrible practice and habit to get into. Thanks for watching! 🙂👍
Iam doing fine tks 4 asking. I do pull some times can u put the hook threw the shackle instead of the pin ive been doi g that ever since i can remember my dad did it tks gary
Since you are a truck/tractor puller, I don't know that it would make much difference. You are loading the shackle inline regardless of the direction of hook up.
Great video very informative! Thank you sir
Thanks for the compliment. Also, thanks for watching! 🙂👍
Great informative video:-) I have a couple of 4 1/2 ton shackles that I keep in my flatbed, and now I know more about them. Thanks for the video.
What does a cream shackle look like? I don’t think I’ve ever touched one before. I have seen several different size carabiners before, but I wonder if this is completely different?
As you could see in my crane video, I did not have reading of any sort because of the type of thing I was lifting, however this would be extremely helpful for moving heavy your containers.
I really wish my big crane would’ve come with some rigging accessories. That’s pretty much the only draw back to it. However if you want some information about where to get the model comment about it on the crane video and I will post The info for you.
A crane shackle is similar in shape to a horseshoe. However it is made from rounded material and has a removable pin that closes the open end. The pin is threaded and screws in. Hopefully that was an adequate description. If not, let me know and try to give more detail. Thanks for tuning in! 🙂👍
Is there a difference between a clevis and and a shackle?
my job is rigging.
I agree that tips for the safety.
i always follow the book.....thats my the best way.. .. rigging the one of the dangeous job. support 100%
keep it up boss......
Thanks for the rigging lesson.
I've delivered to sites before and some of the rigging has been questionable at best. I'm a driver not a rigger.
The only time I've seen shackles work loose is doing duty cycle type work- mostly wrecking ball and clam bucket work.. and we wired the shackle pins to make sure they didn't back off...
+Michael Owen, same here. It's a pretty safe bet that I won't be clamming or using a wrecking ball on the ole Tadano. Lol. Thanks for watching! 🙂👍
In those cases you should be using a shackle with a bolt and a castellated nut. We had the draglines connected to magnets with a shackle with a bolt. The material handlers also used one to hang the magnet.
I think you hit it on the head. You need to have common sense to start with. Thanks for sharing the video.
Yes, common sense, which should now be called uncommon sense, is definitely a prerequisite for this kind of work. Thanks for watching! 🙂👍
This is a very good video. I'm 32 years crane operator. Local 487B Miami, with them for 17 years. Currently working in Israel, with Intel-Israel. I'm lifting 11.5 ton 50' beams. All day, I use 8.5 ton shackles on each end. With 2, 18 feet 8 ton " High Performance roundsling, hooked to 2, 10 foot 16 ton chains. I keep it long in order to stay within the 45 Degree angle. Also, from time to time I slide my roundslings so the I do not work with the same area. Yes, I keep my crew rigging with the screw in the hooks.
hey idk if this is cheating but can you show how to spin the box or drift a box ???
awesome shaq fitness, I'm not sure I understand what you are asking. However, many thanks for watching! 🙂👍
Have you found a video on this ?
Very informative, makes sense, just never really thought about it. What about putting the shackle directly on the load like with ears, I assume pin in the ear is correct?
Well, I guess in the last 30 seconds you showed that. So never mind.
Thanks for watching! 🙂👍
The only reason to turn the shackle pin up is if you do have a endless in bottom (towards the load) because when it tightens up on the load it may roll the pin.
Yes you can turn a shackle 90degrees (side ways) it’s called a 90 degree offset and the shackle is good for 50% capacity. Why would you though? No idea...
Just like “never saddle a dead horse” well why is that? It has nothing to do with the saddle of the clamp on the dead end, it has everything to do with not putting the bolt-end of the clamp on the live end. So basically it’s to keep your ass from crimping the live end of the cable. “fun fact”
Cool Beans.
1. It is confusing to say that just because you take a different angle to lift an object that it increases in weight.
I think much better would be to State the actual physics where the force applied on the shackle would increase if the angle-of-pull becomes too parallel to the ground.
In a former life I looked to become a rigor working with cranes. My studying off an online Union manual was to state to keep the angle of pull close to 45° to the direction of oull. My affliction with acrophobia pretty much kapashed that dream.
2. While it may take 7 full turns for the pin to unscrew, may you tell me at which turn of the screw that the shackle is no longer rated for 13 tons? One turn, Twontrina, Three...???
Seems to me that a clevis would be a better choice than a pin. The clevis can freely rotate without unscrewing. The pin that goes through the whole of the pen can be pulled out with a finger no tools required faster than rotating a pen 7 turns. But this is just me: what do I know...
With the turning of the pin, I was always taught to engage all threads
One quarter of a turn of a acrew in seven threads is only 1/28th of an turn from fully engaging all threads.
I find common sense is not so common anymore. I was taught to back off the pin also. Good job!
Jim Posey, it should now be referred to as uncommon sense. Given there are so many who don't possess it. Thanks for watching! 🙂👍
You are right on the money my friend.
I see in another video you had a 40/60 , does that belong to your company?
@@jimposey3963, it does belong to our company. We also have a 25/35. They are great machines.
We have a 40/60, we’ve had 10 years now and it still amazes me what that machine will do.
Bit late to the game here, but I found another video showing strain tests on shackles, which I think illustrates why you don't load from the sides of the shackle. Hope this helps someone: th-cam.com/video/66BXmM_JuBI/w-d-xo.html
Jimmy, are you going to cover estimating center of load and center of gravity for irregular pieces?
For a few decades, I've been putting anti-seize on pin threads, and backing the pin off a little for most lifts. Never had a pin back out even a little.
This video was awesome instruction for using shackles! Thanks.
David Sonnen, I will try to make a video on that. Or atleast talk about it in a video. Thanks for the idea, the feedback, and for watching! 🙂👍
i dont like using anti-seize on any rigging, just bacause it can get onto the strops. And atleast where i work any grease, oil, paint etc. on strops means we dont use it. Norwegian law.
@@mattis537 Makes sense. Grease, paint and solvents destroy synthetic straps. I started using anti-seize on screw pins when I was working on the Pacific coast. Even galvanized pins rusted in salt water after a while. Anti-seize reduced that problem. But, we did have to be careful not to get any lubricants on straps
would you think a 1" Crosby shackle is over kill for use with my jeep and 10,000 lb winch? I bought one encase I needed to use my snatch block on a heaver load.
Great video...very educative
Yehmen ! I worked “with” many riggers as they were the ones who would move the equipment that I was responsible for aboard naval vessels (surface craft & submarines). I often say, I would enjoy being a rigger if I wasn’t a marine machinery mechanic for PHNSY shop 38 (retired after 35yrs). Needless to say I have many stories to share (both ah ha’s & holy crap).
Great video I enjoyed this one and learned something new i never knew about the 45 degree limit on a shackle
As with anything, there are exceptions to the 45° limits. However, proper deductions must be made. Thanks for watching. 🙂👍
Is it okay to use a chain fall (as a sling) when picking an asymmetrical load (with no pick point) to shift the center load of gravity below the hook?
This was an excellent display of knowledge. Thanks for sharing brother!
more rigging please
Ill e mail u soon.
If straps get a twist in them? Is it a major safety concern or just hard on them with unwanted wear? Thanks for bringing common sense back to the masses!😎
It depends on how much twist. Technically it should all be twist free. However, if there's a few gentle twists that aren't rubbing on something or causing damage to the strap, I generally don't get too concerned. Thanks for watching! 🙂👍
@@ToTheTopCrane
I wondered if they got a single twist if it was grounds to start whole rigging over. Sounds like it just depends on situation. Thanks for answering all my questions!
@@waynetharp, thanks for watching all of my videos! 🙂👍
@@ToTheTopCrane
I truly enjoy them and they just continue to get better. Hope you were able to rest some today before heading back to rat race tomorrow?!?!🏗
Do you always use Bow shackles rather than D or V shackles or a mix depending on aplicación.
I'm new to your channel. Do you have a video that covers using shackles to choke slings?
Per Crosby you can sideload but derate by 50% the WLL on the shackle
What size is that shackle?
Richard Denis, I don't remember what size shackle I used in this video. I think it is 7/8 or 1 inch. Thanks for watching! 🙂👍
Also a lot of guys look at a sling and see basket configuration rating. But for true basket configuration rating you would need to use a spreaderbeam. Even 1° angle is not a true basket
Great video, great instruction. Excellent representation and comments on "real world" situations and how the theoretical is not always the challenge for practitioners. Not sure how you can teach common sense, though, and that is the problem. Effective learnign and knowledge starts with facts first and then the application of the factual knowledge to the real world................not the other way around. In other words, "book smart" first and then practical experience= optimal and safe operator. He implied this when he said you have to "know where to draw the line" and that only comes with the perspective of factual knowledge combined with practical experience. If you don't have the formal, book knowledge of the physics involved in this, you have "monkey see, monkey do" learning and some of the monkeys do things where only luck or some other variable saves them. Unfortunately, their luck runs out with enough repetition of the faulted procedure.
Thanks for the video, very informative! ....13
Thank you, and thanks for watching! 🙂👍
👍🏻
I only drive a 12k telescopic forklift with a 60' vertical and 47' horizontal reach but have always tightened the pin fully and then back off half a turn. Our work it quick paced and very repetitive and never involves any lengthy picks or overnight slinging.
Just found your channel and digging your knowledge ;)
Hey Jimmy! In terms of tightening the pin of a shackle, what’s the length you would consider “awhile” when tightening it all the way. What if something will be up for like 24 hours is that long enough to consider tightening it down plus using something to lock the pin down?
V nice video ...thanx so much sir.From India
Ive been taught that you can load a shackle past its 45s as long as you acknowledge that it is only good for 50% of its rated capacity.
I didn't go into that much detail. But, you aren't incorrect. Thanks for watching! 🙂👍
Kyle - if you look at the tag (should be there) on the strap/sling, you’ll see the type of config you’re talking about. But when you look at the load capacity in that config, it drops drastically. I don’t know if -50% is a constant, but it’s way down. Beyond 45°, you’re past the point of gravitational advantage. Past halfway up and halfway down.
You can have a sling in full vertical with a shackle on its side. Standing "I beams" is usually where a shackle is on its side
Kyle - Hmm, I’m curious as to the type of rigging you’re referring to. Can you explain it more?
Lets say you have a large steel plate thats laying flat. You can blow a hole in it and hook up the shackle. Then to pick it up you would have your sling in one end of the shackle bow which would be well below the 45' mark
Rigging actual examples would be great. Amazing content.
Why not just get a set of 4WAYS
Ha! You did do it! Thanks for the effort. Even saw you sweating on that one! I know you said in your 1st video, this wasn’t going to be a ‘how to’ channel but rigging and cranes go hand in hand. I think it’s important to get proper and correct info out there on rigging. How many times has this happened to you: You’re in the seat, working in the blind. Signal man walks over to the edge of the deck and gives you the ‘get high’ sign. You cable up and as soon as you see the load you say OMG! Also, except with structural iron workers, what’s the first tool they go for to loosen up a shackle pin?? THE HAMMER 😖 and they miss a few times and dick-up your sling. Right? I know you’ve seen it. Back the shackle pin off a 1/4 turn. Great vid and info. Thanks again 👍
You asked for it. So, I made the video for ya. It was HOT in the ole crane building. Glad I didn't spend anymore time in there than I did. Thanks for watching! 🙂👍
Very interesting. I really enjoyed the video. 😊
+Mary Feiden, I was hoping it wouldn't be boring. Thanks for watching, mom! 🙂👍
You have an awesome son. Ya I know you already knew that. 😃
@@adamgipson6151 Thank you Adam. That means a lot to us. His dad and I are very proud! 😊
What size is that shackle?
Good learning video.
Good refresh.
My aha moment was at 4:25 makes perfect sense
Exactly a good rigger should check the shackle every pick
Edgar Sandoval, agreed! Thanks for watching! 🙂👍
Jimmy great info
Thank you...very informative
Hi
Hello
Hey Jimmy
What if you have a shackle and it’s to a tow receiver where it’s fixed solid and your pulling sideways like out of a ditch on the 45° angle. Is that fine or does a shackle need equal load on both sides?
It probably should be loaded in the center of the shackle. But, it's not being used for lifting. So, you will have to use your own judgment. Thanks for watching! 🙂👍
Hindi me Jankari
Novice question. Why don't I see rigging with chains as much as nylon straps? This is heavy machinery and equipment... not trees, so I thought you'd demonstrate with chains.
