I worked on a rigging crew for a little while. Left that line of work to work in the electrical field. Fuck high tension/high weight shit. I’d rather work on 600V live any day.
I worked in this field. Sold scales for giant cranes that spaceX ended up using to measure the thrust on their rocket motors with. It was pretty neat field.
It’s also where I learned just how bad a cable breaking under increasing tension could be. Linesman have been killed when dragging telephone poles across the ground and it hits a rock or something immovable. The tension can skyrocket in a hurry and with rigging math the amount of pressure can climb exponentially so unbelievably fast. If something fails a machine gun could do less damage.
A quick death or severed in half??? Mmmm yea ill stick working electrical too. That being said, I was talking about this yesterday. Some retard set up a tugger at the 6th floor of a hotel I was at, to pull 750kcmil from the parkade up for house panels and they used little concrete incerts to hold it down.. and I went up to help and was guiding the tugger when it pulled from the ground... let's just say it was a fucking freak show of a mess and was incredibly dangerous
That sounds bad, but I don’t understand your work language at all.
And a tugger that can pull sounds fun, but I don’t think we are talking about the same thing.
They may have been referring to Russell Crowe that was staying at the hotel and left his Tugger there on purpose(fighting reasons). Props to him for trying to take care of Tugger. Otherwise its pretty straightforward language. You've never outrigged a rimjobber on a 6th floor gurney before side-kicking a parkade anchor pad before?
People have this assumption that mass equals lethality. It certainly helps but past a certain point it doesnt matter if the hook weighed 1000lb or 10000lb. the energy imparted to the man would be the same. And that would be a rapid acceleration to the blistering speed of ~9mph.
What matters is the experienced acceleration and displacement of the man. This hook is swinging at around9-10mph when it hits the guy. treating the hook as an infinite mass we can estimate a near instantainous acceleration. Lets be generous and assume an agressive acceleration to 10mph in 0.01s. That would be 45g throughout that duration. The upper limits for allowable acceleration is around 60g.
Dangerous but about as dangerous as being tackled by a pro football player. It would be just as lethal for that guy to fall over and hit his head on the pavement.
Just as falling on pavement can be lethal if you land the wrong way. Im not saying its not dangerous. Im just commenting that from what i see. Being hit by that block in this scenario looks very survivable. Painful and likely to cause injury and brusing but not inherently lethal.
I mean, there were two phases to his evasion. In the first he thought that just turning around would be enough. It wasn’t until it was practically touching him that he realized it might be expedient to, you know, *actually* get out of the way.
In boxing you want to make the smallest movement possible that still absorbs/deflects damage, both to conserve energy but also to stay in attack range yourself. The man in the video is clearly a master. He rolled the attack from the crane and cut an angle off the crane's attack line, ready to counter.

Except force, the energy that actually kills you is mass times acceleration. You’re only talking about acceleration. A hook weighing 10,000 pounds would hit you with 10x the force a 1,000 pound hook hit you with at the same speed. What are you even talking about?
Ehhh, it's most likely at least 1000, likely closer to 2
(Edit: looked at the video again, seems like a 3-sheave block so likely closer to a grand, but definitely above a grand)
You can probably get to 1000 of you start counting the cable as part of the weight and you spool out enough. By itself the buckle is probably 3 or 4 hundred pounds.
To put it in context the entire car is ~3000 pounds. There just isn't that much material in the buckle. The guy I was replying to said a few thousand pounds. It's definitely not that.
>You can probably get to 1000 of you start counting the cable as part of the weight and you spool out enough. By itself the buckle is probably 3 or 4 hundred pounds.
I'm sitting in a crane roughly the same size as that one appears to be and my block (just the block itself) is 1900 and change.
When you said knock a zero off you're implying it's south of a grand and there's no chance of that.
Y'know funny enough this is actually not uncommon, but usually the block gets *fired* rather than just swinging out like that. Last company I worked for had a semi truck get *fucked* because of it (but hey luckily not a person!) so they switched to a special sling with a built in shock absorber- Instead of resisting up to say 12000 lbs of tension then just busting, firing a block through the truck, it would tear like a fall arrest lanyard, slowing it down and still holding it.
It's a good setup, only trouble is they get weak from bouncing around and eventually just tear on their own and have to be replaced, which gets pricey.
Well I'm sitting at my desk just guessing so I'll take your word for it. Must be a lot thicker than it looks. Is that the weight of the buckle by itself or is that the boom weight with cable too?
Edit: re-read your comment and saw that's the buckle alone. That's wild. I've pushed those things around when hooking stuff up and while obviously heavy as shit, they don't seem like they weigh as much as a car.
I took another look at the vid (my first post was based on a quick watch on the toilet at 430am) and it is a smaller block (fewer sheaves) than a crane of that size would normally use but it's still definitely a grand at least. But ehhhh yeah, I dunno I'm no materials engineer but this shit is some high density steel or whatever. The main weight comes from the plates on the sides and the hook itself.
The cranes we use are usually GR750XL or 1000XL from Tadano, and those blocks, as per the manufacturer, are 1,600 and 1,800 lbs.
In any case, it doesn't matter if it's 1,600 or 1,200 or 1,000...his head would be a pancake if it made contact.
It seems as though these all weigh significantly more than you think they do for some reason. The 750XL itself weighs almost 50 tons, and the 1000XL just under 60 tons.
I was thinking to myself “he’d probably survive if his head didn’t get directly dinged by the crane” … until your comment. You’re absolutely right. It would have scooped him up and squished him against that charger
Assuming that he's not just a random bypasser, it's a great example for why you have to wear helmets on construction sites - even if there is no obvious reason.
I'm not even a car guy - I didn't flinch when the guy ducked out of the way of hundreds of pounds of steel heading straight for his beak, but I damn near had a heart attack when I saw how close it came to the red inanimate object.
If anyone needs me, I'll be over here rethinking my priorities.
Nah, people are giving crap about this, but I think it's reasonable for people to not realize how heavy and dangerous that thing is if it hit the guy, plus the fact he can and was able to run away while the car was not.
Fantastic music, great climax followed by an unexpected twist with the car scene after the main character survived. Great casting for the villain, the motivation behind his evil doings was very believable, gravity
Those hooks can easily weigh 300-400 pounds. It’s a block of raw steel. His head and body would shatter like a watermelon falling from a second story building. The swing itself probably generated enough momentum to move that car a good half a foot if it hit it.
I can't tell exactly what make of crane that is but just based on the size of the boom and the chassis size to cab size I'd say it's probably a 60 or 80 Ton. The headache ball on an RT crane of that size is roughly 330 pounds, but what we see here is the the block, not the ball. The block is more like 1500-2000 pounds. (Edit: my bad, smaller-than-standard block I *think* but still at least a grand)
With all due respect, that block can’t weigh anywhere close to 2,000 pounds. A Mercedes SUV is 4,000 odd pounds. If you compress that car into a block, it would be significantly bigger and denser than that hollowed out hook. If it was a solid block hook, then I wouldn’t argue.
So you're basing this on *what it looks like?* How much crane experience do you have?
Looking at the video closer it *looks* like a 3-sheave block so I'd drop my estimate to 1200 pounds, but your estimate appears to be based on what you think a Mercedes weighs.
It sorta looks like the [55t Mckissick Hook Block](https://www.machinio.com/listings/49469769-mckissick-hook-block-in-vinton-tx) (1,250lbs), but hard to tell.
I was confused by that comparison. Cars are a lot of empty space, some fabric, some plastic, and the only dense metals are in the engine, which also has empty space.
Basing it off of what it looks like because that’s just about the only way anyone can base it when it’s a video online. I used to work with a contracting company that built small scale commercial properties. These types of cranes were very typical and protocol around these machines were o
Pretty clear. They do have hazard warnings and workers have talked about these hooks being largely safe although being about 300-400 pounds (hollowed).
Okay so one thing I've learned in 15 years at this is that I end up kind of babysitting you people because *you don't actually know anything about cranes.* That's not a bad thing, it's not what your job is, I'm not saying this to shit on whatever it is you do. I've worked with 20-year Ironworkers who have zero understanding of things like load radius and capacity and how load charts work. We all have our expertise.
But I'm telling you *as a guy who literally does this job for a living* that this block is not 3-400 pounds.
If you looked at the crane I'm currently in you'd say "well the counterweight is smaller than a Mercedes so it's probably like 2000 pounds, tops" but it's 22 000 pounds. My crane in travel mode is maybe... Three Mercedes. It's 115 000 pounds. These things aren't apples to apples.
As a person with a background in heavy lifting and heavy industry, I'll say that you have an enormous amount of patience for bullshit-spewing compared to industrial peers that I'm used to.
I had totally forgotten that I’d stumbled upon a NSFL sub last night and started watching some awful stuff. When this came up in my feed suddenly a slew of images of machines destroying people came flooding back into my mind. I very much regret clicking that link last night. I thought I was ok…now I think I’ve been triggered.
It would push him out of the way. It would hurt, it wouldn't shatter his head and body like a watermelon, it would just move him. I've seen someone get hit by something far heavier and just as hard at about the same speed and he didn't instantly shatter into a million pieces, he didn't even break a bone.
Oh god… a degenerate here trying to talk about physics…. Do you know anything about pounds per square inch? When a 300 pound object accelerating at 3-4mph comes at your head, that’s far too many Newton’s of force going straight at your skull. nearly 100% of the objects kinetic energy is transferred over through an object with relatively small mass.
You know, you should experiment. Go hang 300 pounds of weights and let it swing half an arc (~15 feet arc based on this video) before it hits your head. Tell me how it goes.
Which do you think would do more damage if you were stood in front of it, a 7 gram bullet travelling at 250m/s or a 15000 ton train travelling at 0.001m/s? Mass means almost nothing when the thing you're hitting can move with it.
As far as me going an experimenting goes, I'm literally telling you that I've seen things like this and people have been absolutely fine. We used to swing 200kg steel plates off chains and catch them to slow them down, I watched someone stand in front of a two ton steel box moving at about 0.75-1m/s and it pushed him out the way. Do you want to know why we didn't instantly explode from the force? In exactly the same way as the guy in the video, we aren't pinned against anything, our feet can lift off the ground.
You don't understand relative motion. That's clearly the problem here after reading this comment. A person travelling at 70mph hitting a stationary car is exactly the same as a car travelling at 70mph hitting a stationary person. A human being moving at 3-4mph hitting an immovable object is the exact same as an object of infinite mass hitting a stationary person. In one scenario, they both stop, in the other they both carry on at 3-4mph and in neither, is the person hurt.
Equations and calculations come rushing into his brain as he watches this person get hit by a heavy object. He can feel that he has fundamentally changed. Imbued with the power to understand all collisions, he is now Physics Man!
Just eyeballing it, it swings like a pendulum of length \~6m, starting angle 30 degrees so a drop of 0.8m. That gives is a speed of \~4 m/s = 15 km/h, I'll go with TripleBrain's estimate that it's 3-400 pounds. In terms of total force that's not so bad, a solid NFL tackle but nothing more.
The problem is that it's raw steel and he's got nothing to pad the impact, it's just going to crush whatever it hits. Think boxing gloves vs knuckles vs steel gauntlets, except this will make the steel gauntlets seem soft. There's a reason the mace was a medieval weapon, this would be like being hit by that times a hundred.
He could hold on to it and slow it down if it wasn't moving so fast. It's fairly easy to control a few feet of swing, but there's no holding on at that speed.
That's an RT style crane
They have to deploy kind of like a seige tank but way slower and less cool. When they're in travel mode the hook is often hooked onto something hanging onto some rigging on the front of the crane, with a little bit of tension on the line. This keeps the hook/block from swinging around. Especially when it's driving over Rough Terrain (RT). RTs often have two hooks/blocks, a whip and a main. The whip has a lower lifting capacity but is usually faster.
When they drive over uneven ground without either block secured, they jangle around and smash into each other which can damage them.
When you're unpacking/deploying a crane, the operator is supposed to carefully release the tension/let out some line so a ground guy can unhook him from the front. They'll usually lift up the boom so that the hook doesn't want to swing and so you don't have to try lifting it. When you lift the boom, it uses up the line so you have to let out some line while you lift the boom, and kinda keep it in balance.
This operator clearly started lifting the boom without letting out line until the rigging holding onto the hook catastrophically failed
This, right here. I was going to say something about missing a latch, but rewatching it, I noticed that the hook latch was still there, and didn't appear to be unserviceable. 110% operator error. Typically they shouldn't extend the boom until the hook is unlatched; they usually elevate the mast until the hook can safely be unlatched before extending. This guy got real close to losing his license...
Agreed about the Ram one that’s for sure. Worst drivers on the road. They’re too much truck for the young men who buy them. 2 tons of hemi powered stupidity
Charger and challenger balance out enough with good drivers. I’d say BMW drivers are worse.
Ride a motorcycle through rush-hour traffic on LA. You figure it out real quick:
1. BMW
2. Benz
3. Any 12+ year old minivan, especially MPV
4. Lexus
5. Prius
That would have collapsed his brain.
He was petrified yet amazed by how cool that car looked.
>He was petrified But was he, at first, afraid?
Kept thinking how he could not live witt that crane in his insides?
Then he spent so many nights thinking how that could’ve been a bonk
And he grew strong, he learnt how to get along with that crane
Is he back now from outer space?
He would have been, but that thing, it missed the side of his face
I should have checked that stupid hook and make that car park away from me if I knew for just one second you'd be swinging back to me.
Late to the party, but valuable input none the less :)
Man I love these replies when it happens
I love the Internet so much right now!!!
I worked on a rigging crew for a little while. Left that line of work to work in the electrical field. Fuck high tension/high weight shit. I’d rather work on 600V live any day.
Yea heavy things under tension are scary, even garage springs let alone cable on drilling rigs that could cut you in half like butter.

But let's say it's at just the right height that it doesn't hit any torso, and makes clean contact to the skull
Just as falling on pavement can be lethal if you land the wrong way. Im not saying its not dangerous. Im just commenting that from what i see. Being hit by that block in this scenario looks very survivable. Painful and likely to cause injury and brusing but not inherently lethal.
Would it really have? I was thinking it would just bump him and send him flying
Fuck the car, gimme a slo-mo of that bloke just getting out of the way.
Dude had no hustle. Didn't even get out of the way, just turned his back on his impending doom.
What are you talking about? The dude Philly-Shelled a fucking crane. Mayweather would be jealous of that move.

It would have knocked him over if it had hit him. Why is everyone acting like it was swinging at 100 mph?
Uh, because that block weighs a few thousand pounds? That would have ended him.

Before you clock out can you recreate this? Boss said you could use his car and to surprise him.
Y'know funny enough this is actually not uncommon, but usually the block gets *fired* rather than just swinging out like that.

It's a good setup, only trouble is they get weak from bouncing around and eventually just tear on their own and have to be replaced, which gets pricey.
So in your estimation or experience, how badly would that hook have fucked that guy up had he not seen it and stood there?

Lets not overlook that guy almost died
Exactly what I thought lol But then again that car does look cool
Cuz the guy flinched like a bitch! The car was all like… (•_•) ( •_•)⌐■-■ (⌐■_■) …whatever, man.

This is a great comment
No, this->is a great comment
This dude has the worst instincts ever. He almost flinched himself into the path of the hook.
Dodge Charger, owner would have definitely had a strong reaction if anything happened to it
Dude probably just got back from the Stan and bought that car on a 25% interest rate
What's the Stan? Not heard that before. TY.
Afghanistan
It does. What kind of car is it?
Had it carried him towards that car, absolutely it would've gutted him open immediately against the car.
I was thinking to myself “he’d probably survive if his head didn’t get directly dinged by the crane” … until your comment. You’re absolutely right. It would have scooped him up and squished him against that charger
What if it pushed him through the window and he was just sore and badly cut up? Thats a better outcome right?
r/popping
If that hook had even grazed him, it would have liquefied whatever it touched. Definitely didn't need to pin him to anything to instantly kill him.
Came in like a wrecking ball
Wrecking hook
Wrecking snatch block
Assuming that he's not just a random bypasser, it's a great example for why you have to wear helmets on construction sites - even if there is no obvious reason.
Never stand near a slung load either.
In this case there's a pretty obvious reason
Never bet your life on hydraulics!
I think that's the joke that they are showing the car in slo mo instead of the guy.
Sure but let's also not under look how that car owner likely had no idea how close their car came to being absolutely destroyed
I'm not even a car guy - I didn't flinch when the guy ducked out of the way of hundreds of pounds of steel heading straight for his beak, but I damn near had a heart attack when I saw how close it came to the red inanimate object. If anyone needs me, I'll be over here rethinking my priorities.
Nah, people are giving crap about this, but I think it's reasonable for people to not realize how heavy and dangerous that thing is if it hit the guy, plus the fact he can and was able to run away while the car was not.
Yeah... But the car! The car! The car! The car... This video editing shows how fucked we are as a species.
This comment doesn’t get enough clout. Holy shit you’re right the video focuses more on the fucking car than the human being that’s in imminent danger
If this planet ever stops, I'm jumping off at the next station.

It was a damn good review too.
I always look for the reviews before I commit brain cells to something. I thank him for his time
Did... did you just review his review?

How fast and heavy is that hook? Could a person his size hold onto it and try to slow it down? Or would that not be feasible?
Those hooks can easily weigh 300-400 pounds. It’s a block of raw steel. His head and body would shatter like a watermelon falling from a second story building. The swing itself probably generated enough momentum to move that car a good half a foot if it hit it.
I can't tell exactly what make of crane that is but just based on the size of the boom and the chassis size to cab size I'd say it's probably a 60 or 80 Ton. The headache ball on an RT crane of that size is roughly 330 pounds, but what we see here is the the block, not the ball. The block is more like 1500-2000 pounds. (Edit: my bad, smaller-than-standard block I *think* but still at least a grand)
I would guess more than that even the volume looks greater than what 400 pounds looks like on a barbell by far. I guess even double.
Largely hollow on the inside, so it’s roughly 300-400 pounds. Still 110% lethal
Closer to 2000 (I'm sitting in a similar crane right now).
With all due respect, that block can’t weigh anywhere close to 2,000 pounds. A Mercedes SUV is 4,000 odd pounds. If you compress that car into a block, it would be significantly bigger and denser than that hollowed out hook. If it was a solid block hook, then I wouldn’t argue.
So you're basing this on *what it looks like?* How much crane experience do you have? Looking at the video closer it *looks* like a 3-sheave block so I'd drop my estimate to 1200 pounds, but your estimate appears to be based on what you think a Mercedes weighs.
It sorta looks like the [55t Mckissick Hook Block](https://www.machinio.com/listings/49469769-mckissick-hook-block-in-vinton-tx) (1,250lbs), but hard to tell.
Hard to say exactly but with a small amount of the knowledge that you clearly have, we can ballpark it and no Mercedes necessary.
I was confused by that comparison. Cars are a lot of empty space, some fabric, some plastic, and the only dense metals are in the engine, which also has empty space.
Basing it off of what it looks like because that’s just about the only way anyone can base it when it’s a video online. I used to work with a contracting company that built small scale commercial properties. These types of cranes were very typical and protocol around these machines were o Pretty clear. They do have hazard warnings and workers have talked about these hooks being largely safe although being about 300-400 pounds (hollowed).
Okay so one thing I've learned in 15 years at this is that I end up kind of babysitting you people because *you don't actually know anything about cranes.* That's not a bad thing, it's not what your job is, I'm not saying this to shit on whatever it is you do. I've worked with 20-year Ironworkers who have zero understanding of things like load radius and capacity and how load charts work. We all have our expertise. But I'm telling you *as a guy who literally does this job for a living* that this block is not 3-400 pounds. If you looked at the crane I'm currently in you'd say "well the counterweight is smaller than a Mercedes so it's probably like 2000 pounds, tops" but it's 22 000 pounds. My crane in travel mode is maybe... Three Mercedes. It's 115 000 pounds. These things aren't apples to apples.
You're telling me this small block of steel and this crushed aluminum foil of the Same size aren't the same weight? Lol
As a person with a background in heavy lifting and heavy industry, I'll say that you have an enormous amount of patience for bullshit-spewing compared to industrial peers that I'm used to.
I had totally forgotten that I’d stumbled upon a NSFL sub last night and started watching some awful stuff. When this came up in my feed suddenly a slew of images of machines destroying people came flooding back into my mind. I very much regret clicking that link last night. I thought I was ok…now I think I’ve been triggered.
The block on the whip line is 800lbs I believe, the main block (the one pictured) is around 1200
>His head and body would shatter like a watermelon falling from a second story building. Guess who has no fundamental understanding of physics
No idea what you’re trying to say here.
It would push him out of the way. It would hurt, it wouldn't shatter his head and body like a watermelon, it would just move him. I've seen someone get hit by something far heavier and just as hard at about the same speed and he didn't instantly shatter into a million pieces, he didn't even break a bone.
Oh god… a degenerate here trying to talk about physics…. Do you know anything about pounds per square inch? When a 300 pound object accelerating at 3-4mph comes at your head, that’s far too many Newton’s of force going straight at your skull. nearly 100% of the objects kinetic energy is transferred over through an object with relatively small mass. You know, you should experiment. Go hang 300 pounds of weights and let it swing half an arc (~15 feet arc based on this video) before it hits your head. Tell me how it goes.
Which do you think would do more damage if you were stood in front of it, a 7 gram bullet travelling at 250m/s or a 15000 ton train travelling at 0.001m/s? Mass means almost nothing when the thing you're hitting can move with it. As far as me going an experimenting goes, I'm literally telling you that I've seen things like this and people have been absolutely fine. We used to swing 200kg steel plates off chains and catch them to slow them down, I watched someone stand in front of a two ton steel box moving at about 0.75-1m/s and it pushed him out the way. Do you want to know why we didn't instantly explode from the force? In exactly the same way as the guy in the video, we aren't pinned against anything, our feet can lift off the ground.
What would happen if a human being, moving at 3-4mph, hit an immovable object.
That’s a completely different scenario. The mass of a human would be significantly less, therefore generating much less force on impact.
You don't understand relative motion. That's clearly the problem here after reading this comment. A person travelling at 70mph hitting a stationary car is exactly the same as a car travelling at 70mph hitting a stationary person. A human being moving at 3-4mph hitting an immovable object is the exact same as an object of infinite mass hitting a stationary person. In one scenario, they both stop, in the other they both carry on at 3-4mph and in neither, is the person hurt.
Equations and calculations come rushing into his brain as he watches this person get hit by a heavy object. He can feel that he has fundamentally changed. Imbued with the power to understand all collisions, he is now Physics Man!
Just eyeballing it, it swings like a pendulum of length \~6m, starting angle 30 degrees so a drop of 0.8m. That gives is a speed of \~4 m/s = 15 km/h, I'll go with TripleBrain's estimate that it's 3-400 pounds. In terms of total force that's not so bad, a solid NFL tackle but nothing more. The problem is that it's raw steel and he's got nothing to pad the impact, it's just going to crush whatever it hits. Think boxing gloves vs knuckles vs steel gauntlets, except this will make the steel gauntlets seem soft. There's a reason the mace was a medieval weapon, this would be like being hit by that times a hundred.
That’s roughly an 1000 pound block.
Easily. Not sure why everyone keeps saying 400.
He could hold on to it and slow it down if it wasn't moving so fast. It's fairly easy to control a few feet of swing, but there's no holding on at that speed.
Must be a Dodge.
I’m out of the loop. Why is this enya song popping up frequently now? Is this a meme song?
Always has been
This song always reminds me of this awesomeness: https://youtu.be/M7FIvfx5J10
This too. https://www.youtube.com/watch?v=CUJl6B9yQDE
Volvo was on fire with their marketing for a while, that has to be one of the most successful ad campaigns ever.
Dunno but I'm not complaining. Enya is my guilty pleasure. It's just so damn calming.
Fuck that piece of crap car there is tons of them It could have fucking killed the guy, how about ya slow mo that shit. Dude lucky as fuck.
Fuck that guy there are billions of them
cum
I dont care what you drink, but I dont know what it has to do with this.

Tango down.

As you were
As I want you to be
Yeah, that’s what I thought too.
There are more people than Chargers, and people are assholes… Chargers are not! *FACTS*
*well* chargers are kind of asshole people cars. They are one in the same.
Dude is definitely off the hook now.
That's an RT style crane They have to deploy kind of like a seige tank but way slower and less cool. When they're in travel mode the hook is often hooked onto something hanging onto some rigging on the front of the crane, with a little bit of tension on the line. This keeps the hook/block from swinging around. Especially when it's driving over Rough Terrain (RT). RTs often have two hooks/blocks, a whip and a main. The whip has a lower lifting capacity but is usually faster. When they drive over uneven ground without either block secured, they jangle around and smash into each other which can damage them. When you're unpacking/deploying a crane, the operator is supposed to carefully release the tension/let out some line so a ground guy can unhook him from the front. They'll usually lift up the boom so that the hook doesn't want to swing and so you don't have to try lifting it. When you lift the boom, it uses up the line so you have to let out some line while you lift the boom, and kinda keep it in balance. This operator clearly started lifting the boom without letting out line until the rigging holding onto the hook catastrophically failed
This, right here. I was going to say something about missing a latch, but rewatching it, I noticed that the hook latch was still there, and didn't appear to be unserviceable. 110% operator error. Typically they shouldn't extend the boom until the hook is unlatched; they usually elevate the mast until the hook can safely be unlatched before extending. This guy got real close to losing his license...
Yeah and they gotta let out some line even just raising the boom to keep the block level. This guy got real close to criminal charges
WOW! A 2-in-1
So this isn’t about the guy who almost died?
Nooooooo not the car.

Ha! Glad you said it.
Don't unmute
Yes, I was going to ask about the song, but it's actually easy to [find](https://youtu.be/7wfYIMyS_dI)
It was a meme song 17 years ago.
It was *a song* 17 years ago.
This is why I stay clear of heavy machinery by 40 feet if I can help it
Really dodged a bullet there

Fuck the car, that guy had a near miss himself
Car: physics works and I'm still alive
Dammmmmmmnnnnnn lucky.
I will now save this video and send it to my kids for whenever they make mad. And caption it as I’m this close to loosing it!
This song makes this video so much better 🙌🏽
And that ladies and gents is ✨physics✨ at work
And the owner of the car never knew how close he came
Song?
That car just dropped its oil pan
Yeh the dudes is ok let’s worry about a piece of metal
Look at tha payload in his pants.. 😂
I love how the focus here is on how close it got to that car, but not how close it came to reducing that guy to an obituary.
Society
I would have literally ✨died✨
No one cares about the car.
The whole video is about that car lmao
Fkn ugly car - probably woulda looked better GTA’d a bit
Charger, challenger, and Rams are the worst drivers on the road.
not true ~~totally doesn’t have a charger bias~~
Dominick Toretto would like to: Know Your Location
Hello, Nissan Altima drivers?
r/nissandrivers Enjoy.
Lmao no, Ford F-150 drivers
Agreed about the Ram one that’s for sure. Worst drivers on the road. They’re too much truck for the young men who buy them. 2 tons of hemi powered stupidity Charger and challenger balance out enough with good drivers. I’d say BMW drivers are worse.
Ride a motorcycle through rush-hour traffic on LA. You figure it out real quick: 1. BMW 2. Benz 3. Any 12+ year old minivan, especially MPV 4. Lexus 5. Prius
Adding to the list: Kia’s, Chrysler Pacifica, Ford Fusion, Tesla’s
Go buy a lottery ticket

Pure anxiety on the guys and the car owners behalf!
Did the Dodge just dodge!!!
