I hauled coils for 10 years, and I can tell you the reason that coil let go and hit the truck cab is because it was improperly secured. They should be double or triple chained in a coil rack. There is considerable training involved in hauling steel. You can't just throw a chain over it and go.
Edit: best answer I've heard so far: uncoiling is a greater concern than poor securement. Putting it that way allows it to be secured easily but more importantly prevents explosive uncoiling. If you think loading/unloading them is harder, that isn't the problem of the folks on the road. Their safety supersedes your convenience. The uncoiling argument satisfies the only concern that matters.
Original: Why don't they transport them flat? They seem like a cube in shape [I don't mean it's a literal cube for people who keep misunderstanding this. A cylinder can be described as a cube / cubic inches / "it goes in the square hole", get it?] or are they taller than wide so they wouldn't fit? I know it's make the loading/unloading slightly more of a pain but then you avoid this whole rolling loose problem. It's easier to handle them in a stable location than rolling down the road with randomness around.
Damn, I'm glad we have a professional here. I would have thought it slipped because the driver didn't chant the magical incantation properly.
@@TrahlocI think the main reason why you want them rolled is that it does not have a fixed lenght: you can establish how much of it you need, depending on the work to be done.
@masafromhell I don't think he's debating rolling steel, but transporting the rolled steel on its rolling surface instead of tipping it on its side. I imagine at least one reason is that it seems harder to secure them to the flatbed. Tho with that said you could probably make a specialized pallet for them that you could basically weave numerous chains through, so I don't know.
@@Raigosai their own weight would secure most of the load imo. I'd imagine two strong chains Xed over would help resist the initial slip and gravity would do the rest. The example video wasn't a truck flipping over, it just braked hard.
As my trainer told me:
You can over-secure a load as many times as you want, but you can only under-secure it once
Why not lay the coil down flat? Seems a bit daft to chain it down on the round side, such that it wants to roll forward every time the truck hits the brakes!
@@Mr.Ekshin How would you get it off afterwards?
@GoranXII why aren't they rotated so they would roll sideways instead of forward and backwards
@@RichieKrol Harder to get off. In an 'eye-sideways' configuration, a forklift with a spindle can load them, but a 'eye-forwards/backwards' setup would be more difficult.
@GoranXII makes sense. Would it be safer though, I wonder. And if so would that increased saftey be worth the increased difficulty or even custom machinery. I'm guessing these accidents aren't so common that proper training and chains are good enough.
As I was typing this I started thinking about the mass of one of those rolls. If it were sideways even a small wiggle from the roll would be enough weight shifting side to side it might be hard to control
Those spools are insanely heavy, it's basically a solid piece of metal, not to mention the dangers of unbinding them and having the spring out, you can get a good demonstration of this of (and don't try this at home) you were to take a 25ft tape measure apart and dropped the coiled tape out without holding it it will practically explode because it unwinds itself so rapidly
i operate a heavy gauge level line, heaviest coils i deal with are up to 70k lbs
its not that serious if you aren't a baby about it

@@Loothy88no, no… let him do it…
But. My tape measurer only got a laser pointy thing in the front when I digitally uncoil my tape measurer
I’ve known these to be called suicide coils, for the reason shown in the video.
I’ve known an owner/op in the industry that hauled a LOT of these. He had bought a flatbed and he personally welded a steel frame on the front of it with angled supports and gusseted t-joints. Then he would have the loaders put the coils on with the first one butted up against that steel frame and each coil butted up on to the next.
Lastly, everything gets chained down and if I remember correctly, he used G80 - 1/2” chains with a minimum of 4 per coil with 6 used on the coils located on the ends. 4” straps were used to secure any loose chain ends, and were used to help keep the coils tight to each other. Something to do with the fact that the coils manage to do a rotational slide sort of thing sometimes, causing a touch of slack. I don’t know, but that’s what he told me when I asked 6 years ago.
He also said that he rather go overkill on the securement than getting run over by his load. Did a lot of heavy haul, and moved more coils per load than some drivers were comfortable with.
Well, in the uk we have trailers with a bid 'v' in the centre running along the trailer, you drop the coils in and strap. Can't roll forward or backwards because they are stuck in the v.

Ha only if morons chain bind them
I live near Pittsburgh, we had so many of these fall off the flatbeds hauling them over the years that the high school driving instructor would give warnings about driving next to them. We had a horrific accident when a truck carrying 3 rolls lost its brakes coming down a hill. There was a T intersection at the bottom so the driver had no chance, either he was going straight into an occupied building or he could try to make the left turn and know he would flip the truck. He tried to make the left. The truck did flip and took out a few parked cars but the rolls did a lot more damage. The first roll smashed through the cab of truck killing the driver and only stopped when it soft dirt and a concrete wall , the second one buried itself in a building, and the 3rd landed on top of a car that was traveling through the intersection. The woman in the car was was killed and her car was flattened to about 6 inches.
This was back in the late 70s and I still can't drive near a truck carrying coils without thinking of it. I never drive next to one unless I can pass it as fast as possible. If you get behind a truck carrying coils, pipes, logs, or anything strapped down, look at the straps, if they are loose, call a cop. After working around a lot of different shippers I've found that a lot, not all, of them don't secure their loads properly and they never learn until they are hit with a big fine.
JESUS IS COMING SOON🔥🔥🔥 REPENT TODAY AND TURN AWAY FROM YOUR SINS🙏🙏
Don’t call the phucking cops, alert the driver! As a former flatbed trucker myself, I guarantee you he is the one ultimately responsible for securement and would care to know immediately if something is loose.
I tried to comment something here but ytb seems to block it.
Since the risk is death for a bystander, I think losing a license as a punishment is the only way to make sure these are secured properly.
carrying steel coils on these flat bed trailers should be illegal. I am German and did my apprenticeship 3.5 years at ThyssenKrupp and worked there an additional 4 years. And I worked at a city port were they load/unload these coils from river ships to trailers. I have never heard of an accident with these coils. They are always only transportet on special frames that are like classic door stoppers on each side of the coils, if you know what I mean, and the stoppers are welded to the trailer. So they would need to roll up-hill to move. I have NEVER seen them transported on a flat surface
I seen a picture of a group trying to steal one...rolled it off the dock into a pickup bed...flattened the pickup...😂.

My brother hauled these for a time. Said one of the most aggravating things was being told he'd have to tarp them only to get the delivery point and seeing all their other coils sitting in the yard rusting.
That aggrivated me too, until I asked one of the people at the plant I was delivering it too he said the reason they need to be tarped is because the chemicals used in/on roads can weaken the steel on the molecular level. He said the rust on them is only surface level and has no effect on their process, road chemicals however can completely destroy a coil.

I worked at a factory that made wheeled tool boxes, ten foot shelves, etc; all made out of sheet metal. Met a guy missing half his hand and parts of his face. He said one of the rolls “blew up” because it wasn’t rolled right. Didn’t know metal could just BLOW UP from its own pressure.
I work in Shotton steelworks in the UK and we make cold rolled coils, we have very strict strapping procedures that have to be carried out before we let a trailer head out, some of the videos you see including the first one is shocking how poorly some countries secure their loads, a few years ago we had a trailer tip over onto it's side as a driver went too fast around a corner, every coil was still firmly strapped to the trailer despite being on it's side, it's really not hard to put a few extra straps on these coils yet it will probably save your life or other members of the public in the event of an accident

It's the same energy as "if human trafficking is illegal, why there still human trafficking everywhere".
Coils are safe to transport IF you strap them correctly, whenever hauling thlse death traps overkill is the norm, use all your chains ( I have used 9 when it required 6 to haul 46,000 lbs coil) then throw a couple of straps,cross them around the front of the coil and take it easy, it is a heavy single item being moved so plenty of caution is required.
And remember not to slow down too slowly. If someone cuts you off that's their problem not yours.
*not to slow down too quickly
So.. it's not practical to transport those on the flat side down, because you'd need fancy cranes for that?
@@stalinmceizn You would need more intelligent loaders and unloaders, to figure out the center of gravity on them to tilt them, instead of the grunts they are willing to pay.
@stalinmceizn
Eye to the side is the safest way to transport a coil. If it’s cinched down properly it isn’t going anywhere. The trailer will flip over and still be attached to the coil. Standing up on its side is actually the hardest way to tie it down because you don’t have as much control over forward movement.
Absolutely destroyed that diesel cab. Crazy.
It's very heavy but that was 100% on that operator. You can see no blocks and no chain on that roll.
Many traffic accidents occured where I’m from due to these not properly tied up during transportation.

"If steel coils are so dangerous to transport, why do we keep making them?" Is such a ChatGPT question
Steel coils were recently added to the physics-sim BeamNG. These things were terrifying in a virtual environment. I tip my hat to those that handle them on a daily basis.
Hot and cold rolling has nothing to do with how it's spun into a coil. Even flat sheets are either hot or cold rolled, it's a process of making sheets regardless of the form of delivery.

We haul coils on a regular. Currently gave a 30,600lb coil strapped to the deck for an overnight delivery. Never had a problem with coils. Always over secure the load. This coil has six 5,400lb rated chains, a coil tarp and two 4" straps. She's not going anywhere.
obviously that should be manageable, but based on descriptions in these comments of using many chains, I think an issue may be that these many chains are tensioned unequally or become tensioned unequally as the load shifts on such a way that they break one by one.
@Ass_of_Amalek Thus the reason to do load securement properly then initial load check after 30 miles and every 3 hrs or 200 miles till the destination. If your Binders loosen up after your second check, your doing it wrong
@@TruckingToPlease yeah that makes sense, then you're using the shaking of the drive to settle the load. that makes me wonder though: are there automation systems yet that measure and adjust tensions of fasteners on trucks? I imagine it could possibly speed things up and save money if it reduces occurrences of accidental damage to trucks, goods, and personnel. but then again, it wouldn't really be possible to promise such savings to early adopters, and one could certainly imagine giving an electronic system control over the fastening of the load to be a potential point of catastrophic failure.

Instead of asking a stupid question like why do we still make them why don't they figure out a smarter safer way to haul them
There's 3 ways to transport them, in relation to the flat bed that transports them:
Front to back
Horizontally
Vertically
What defines they way you transport them is the unloading equipament they have at destination
Horizontally and back to front positioned coils can be unload with a simple crane and straps or with a "hook" unloader
Vertically oriented coils (which are the safest way to transport as they wont roll) need a clamp unloader, which is not found everywhere.
most coils get transported in rail cars, only the lighter coils come in on trucks, and only on trucks to smaller company's that do low volume
Are you actually implying that the one shot of a truck getting smashed up by a roll happens more than a blue moon?
@@KamalaChameleon if it's chained badly yes, I'm more saying that trains do the bulk of coil transport, I work on a level line that works exclusively with coil we get 100s of coil cars a year and like 5 trucks in that same time, truck transport is far to pricey and inefficient. A truck brings in one, coil car can bring up to 8 depending on width of the coils, you'll also never see a truck with a coils that has a weight much more the 45k
Because we already have smart ways of transporting them?
Why wouldn’t the trucker carry the steel loop on its side so it can’t roll?
Much harder to load and unload safely. Only safer for the transit stage, and if you properly secure it, it's not an issue. Problem is that people get sloppy or lazy with their loads, and sometimes end up paying for it dearly
Some coils will unroll if their on their side the vibration will break the ties so when WE transport them we have special blocks and do them on the side only but I always put extra chains cuz chains might not fail but if I break hard enough the trailer itself has aluminum hooks that I don't trust had them break on me so I put 3 chains for 13k roll or 5 chains for one 28,700k roll and that's one sketchy roll to transport on a semi you have it tight but after an hour the vibration still loosens the wood inside the coil so you need to stop every 30-45 mins like once or twice until it's forsure not going anywhere especially bringing it down from Ohio or Michigan to Tennessee or Georgia roads 😅 its sketchy and sometimes not even worth the price but beats having some other sketchy load
I drove forklifts putting these on flatbeds...
Yeah, they kinda get loaded sideways, much easier to fit more and pick them back up.
@@RSAgilitywhat do u mean "kinda"? It's either laid on its side or not
It can still slide, and even in the very best possible circumstances, where the bed of the truck and the coil are both completely clean and free of lubrication, it only takes a braking force of 0.8g to overcome the static friction and the coil will start sliding. That’s a fairly strong braking force but not crazy - you’d expect to experience stronger deceleration in an emergency brake.
Now consider how much harder it would be to tie down a coil on its side. You don’t have the convenient hole through the middle to attach it, all you can do is add ropes over the top to increase the static friction, or maybe some kind of complicated netting to try to brace it against the bed.
Now you have a new problem: did you tie it down tight enough? How do you know? If it could roll, you’d be able to tell instantly - it starts rolling when you take off. Its movement is governed entirely by rolling resistance, since it’s essentially already rolling. But on its side? You could not tie it down at all and it won’t budge - until it starts sliding. The static friction is so much higher than the sliding friction, you’re not going to find out if you tied the thing down tight enough until it starts sliding, and then it’s definitely plowing through your cab.
Imagine if instead of loading these on trucks, we put them on hundreds of flatbead trailers connected together with a giant engine in front, then we took that special vehicle and made special steel roadways for them, and isolated them from areas where they can do significant damage as well as giving them special crossing zones.
Now imagine they already do this.
they already did, but not all factory that needed this close to a railroad station
@@rentokawaii1216 funny thing.....my factory is close to some rail lines, but they are not used.

It’s only hazardous transporting coil if you do not follow the well established safety procedures.
Seeing that sheet metal flying through those assembly line machines gives me instant terror of deep arterial lacerations.
I worked on a line that made metal door skins out of these coils. The line itself had a light curtain so you couldn't do that, but you still had to be careful when feeding a new coil or clearing a jam. One slip and it's like the gloves weren't even there. I contemplated getting chain mail gloves after slicing my fingers several times.
Instead I just found a different job. Stuck between two women operators that hated each other on 1st and 3rd shifts sucked more than the metal itself, and cleaning the press plates never felt safe.

I do transport the coils with a truck regularly from ThyssenKrupp in germany. It's not a big deal for me
I'm Italian and work with those coils in a factory and you're right, they are not a "big deal", just pay attention and use the right tools (and some of the people in the video totally DIDN'T use the right tools)
some of the coils i work with are to heavy for most trucks, we have to get them by rail. Coils in my heavy gauge level line are up to 70k lbs, one rail car can bring in 5 of them and we get 40 railcars a week.
The issue is that the workers in those shitty countries like in first clip aren't cared for and don't have workers rights 😊
My dad hauled these in the 90s and 2000s in Canada and the US. Great memories. 😊
Hart like Krupp-Stahl.
Where I work, we work with mostly 35 ton or less, coils. Typically painted or glum, that's 24GA or less, for making panels for roofing and flat sheets for "trim" like gutters, flashing, etc. We re-coil after slitting the coils down to 40-42" for the panel lines, and re-sell the waste. We are like 8 months now with no incidents (knock on wood).
On another note, hot roll and cold roll is how the sheets are made, not how it's wound onto the spool. It should be called hot press and cold press instead of rolled, it makes it confusing for some people. Rolling is shaping the steel, not coiling it.
Nucor?
I hauled a coil recently. 47,950 lbs. It had 12 chains and two straps tying it to my deck. I never felt in danger while I took it from Dearborn MI to Lebanon TN.
Fun times.
That's a big boy. When I worked a coil line for door skins, I never loaded one over 25k. Most were more like 15-18. The 25k one barely fit on the loading lift 😂
Hot and cold rolled steel can both come in any thickness. Both exist for different applications, not for different thicknesses. You can get cold or hot rolled bar stock.
I think its more a generalization that cold rolled is the finishing line, where it is down to our customers specs.. hot band straight off the hot strip is definitely thicker but not trough the finishing process.

Redundancy and repetition. When one of these things cuts loose, the driver typically was rushed for some reason. I don’t know how long you worked in any steel mill, but all the ones I’ve been in, safety is third, not first.

I always hated hauling 35-40,000 lbs coils. Not only does the thought of someone pulling out in front of you constantly on your mind while loaded, but when it does happen, those chains could break and go straight through the cab like in the video😂😂😂
Well at some steel mills there is demands that you transport those coils in lowered truck beds.
Typically one roll weighs 80,000, reason you typically only see one on a large semi trailer going down the road. With blocking and multiple chains to secure.
80,000 what?
My mistake, sorry. Large Rolls are 40,000 pounds, that’s 20 ton on one loaded semi trailer.
Transport them better. Thats why vudeos like that truck getting demolished by one its carrying exist. U have to better secure them
that's a genius idea!
id say the majority of coils comes on trains, trucking them is way to expensive, the ones on trucks are locally sold from one company to another for various reasons. the place i work at buys them from competitors selling them cheap cause of defects that wont for them but might work for us
@Loothy88 the company I work for ships coils on trucks all over the country
@chiefusb465 still more expensive then railcar, I've also never seen a truck transport a 1/2in 96 wide coil that can weigh up to 70k
@Loothy88 that wasn't the point, you said the ones on trucks are sold locally. I was just saying that's not always true. But yeah its cheaper to ship in bulk by rail
I will absolutely never work with steel coils ever
In heavy industry work they say a simple rule of thumb: "Use your head or lose your head."
Worked in a stamping factory for 5 years as tool and die, if we didnt have stamping, we wouldnt have the majority of products you see today. All the non moving metal components of a vehicle are stamped, and still even some of those are stamped, fuel tanks, air compressor tanks, chaor parts, your AC unit is housed in a stamped box. Any bracket you pick up is guaranteed a stamped part.
On railroads coils are always locked in cradles. There is no way it can roll, both sides, front and rear are sloped. Heavy coil has very limited ability to climb, also lock holds it in position. Drive slower, like with hazmat, secure it proper way and everything gonna be ok.
Cold rolled steel tolerance dimensions is much more accurate than hot rolled pipes and everything
They aren't dangerous. The coil that exploded was a high strength grade that was further processed cold and they are known to have a lot of stored energy. Hot rolled coils that aren't cooled excessively to make properties don't explode like that. Truck is the worst way to ship coils, but a lot of product manufacturers don't have the infrastructure or location to have the coils barged in or brought in on trains.
Next metal to cover:
Modern day usage of lead. Where it’s applicable and where it shouldn’t be used.
Cold rolled and hot rolled steel does not refer to the way it is rolled into a coil. It refers to the way that the steel is processed. Either can be made into sheets, rods, bars, and other shapes that aren't necessarily coiled for transport. T posts, for instance, are rolled from larger pieces of steel.
Like most things in life, it's only dangerous if handled incorrectly.
I was 16 and working in a sheet metal factory where rolls of steel like this would be delivered. They ranged in weight based on the thickness - between 1-3,000 kilograms. The foreman (my 16 year old friend - no joke!), would use the very tip of the forklift to raise them and install them on the press. Wild.
I worked at Lifetime on a pipe rolling machine, it would take various smaller slices of these massive rolls and feed them into the machine into a large drum. Then I would weld the end of that reel of metal to the next one before the machine pulled too much of that prior reel out of the drum.
It was often quite high pressure because I'd only have enough time to get the weld done right the first time. Else the machine would have to slow down or stop entirely which makes it hard to hit quota.
It was also incredibly satisfying when you pulled off a near perfect weld and with how standardized the operation is you get pretty good at doing that 90% of the time.
While I was doing that, most the rest of the machine was automated. It was something like 20 ft of dies that would bend the strips of metal into the round or square shape, then welded, plunged in a cooling bath, and then cut to size and stacked into large racks.
They use a majority of that pipe to make their famous tables and chairs.
The question is not why we still make steel coils, but rather why we still load them on trucks phucking suicide coil style. I’ve hauled coils among many other things on a big rig, steel and aluminum. And despite best efforts to secure them, the binders do pop loose from time to time. Those are the pieces used to put tension on the chains. Without secure binders, you have no securement.
Have you tried screw binders? Or screw sintches as we call them on west coast of Canada. They screw tight and unscrew to loosen. No "pop"
If secured right, it's not dangerous to transport.
I install and troubleshoot coil processing machinery that turns the coil into cut straight flat sheets for sheet metal processing, and let me tell you they are no joke. The edges are razor sharp, and on our machines the coils are 15,000 lbs. Cutting the bands to release the coil is the sketchiest part lol
i worked in steel company in production! (voest alpine) the coil the first clip weighs around 30 tonns
I worked in a plant that used these coils.
I unloaded them from trucks and then loaded them into presses; machines that formed specific items. Never once had an accident. Totally professional.
For those who seem to keep asking why they're loaded like this instead of on their side, 1: easier to load and unload and less likely to damage the coil and 2: it is a lot easier to properly secure a coil loaded eyes to the side because you can run chains and straps through the eyes. I've hauled coils eyes to the sky and honestly trying to secure them kind of just felt wrong and I felt a hell of a lot more comfortable when I could just run the chains right through them and know for damn sure they'd be as secure as could be if I did my job right.
i work at a firm using such coils in packs (some are about twenty centimeter large,some are 8centimeter) and the dangerous part of those coils is nearly only the inaproppriate securing for transport.second danger from these is if they get unwrapped in stupid ways.if those are secured properly,both for the wrapping and the securing on transport,it's perfectly fine.some of our providers using two to three plastics straps to secure them from unwrapping ,along with a strong scotch to stick the external end of the coil.some use metallic straps which are much more resistant as the plastic ones tends to get cut by the side of the sheet while moving them.the only decision behind these straps is the cost of metal straps.it's just someone thinking it's too expensive,just like the appropriate supports to transport such coils.most often they're just strapped to the trailer instead of having anti-roll blocks between them
All of a sudden RUclips has me running in the opposite direction of steel coils, my feed is full of this
Not a trucker, so real question out of curiosity: Why dont they put coils on their sides when placing them on a trailer? Damages or deformations at the edges of the sheet should be very minimal and would most likely be irrelevant anyway due to further processing that follows.
Another video where the main question is never addressed 🤣
I worked manufacturing for 17 years I can't tell you how many times I seen this happen I watched 2 coils come off the truck on way too work wow what a mess
Coils weigh 20 t each when full, in the UK we have special trailers for transportation. The coil is placed in the bed which is channel running the full length of the trailer, the core points forward. They still secured but that is to hold them if the vehicle tips over. Braking and cornering doesn't allow them to move. One of the worst RTCs I ever saw was a coil that broke free, it rolled through the cab, removing the driver's arm. Onto the road and the rear of a car, the engine block stopped the coil. The driver and the four passengers didn't slow it down. The recovery was not easy.
The transportation of steel coils has always been dangerous.
I never understood why they do not make a trailer that has a pocket where the coil is secured and literally becomes part of the trailer.
Not all trailers have them but some steel companies demands those lowered truck beds but they wanna cheap out on cheap truck drivers cheap trucks cheap transport. And then wondering why they dont have workers anymore...
We use them in the UK - both trucks and trains. I worked for an automotive manufacturer at the pressing plant. All our steel coils were delivered this way from British Steel (and this was over 30 years ago)
Why wouldnt they stack the coils on their side so they cant slide like that?
Why doesn’t the steel industry have a base crate designed and built for those rolls to reduce accidents? They could be stackable so that a number of them could be returned to the mill in a single trip.
1 Reason why they are still made is because the other option is useing premade blanks, and those slow down the process of stamped metal machining. Coils are more continuous and therefore speed up the manufacturing process.
I was the GM for manufacturing company that used large coils for our product. A piston on one of the tow motors let go and the coil fell to the floor. It's amazing how badly it rattled a100,000sq ft building. It felt like a bomb went off! The driver got shot in the face with the hydraulic fluid, but was ok. They are VERY dangerous.
Why they don't just transport the rolls with heavy duty chocks?
The means to stop round things from rolling have been around basically since the invention of the wheel. Chocks are a stupidly simple, absolutely effective, and dirt cheap solution that's been used...forever.
I worked in a steal coil plant for 3 days and they threw me away for nothing
1)Unless I'm mistaken, steel sheets are just cut/formed from coils somewhere else, so if you can do that in house, it'll save money.
2) Cutting steel into sheets creates a lot more waste. Think about cutting 45" parts from a 100in sheet vs a 1000ft coil. every sheet will have ~10in waste (100in total), whereas the coil will just have 10" at the end.
TLDR: Coils save big businesses money.
Steel coils are dangerous af, also some may look cold but still be scorching hot
“If it’s so hard to transport, why do we keep making them?”
Because we need them
I work in a steel factory in France and the coils are not loaded this way at all. They are turned 90°, in a V shaped trench against 2 metal poles and strapped to the bed. Brake as hard as you want, it will never roll into the cab.
I work for a company in south carolina that makes everything from panels to trim with the coils. It's fascinating process.
Just use a specialized trailer like Krone Coil Liner with "Coil troughs" and the transport will be no problem
Most shippers will not allow rebar, coils and other dangerous items to be transported unless a headache rack is installed! I had a trucking company with my dad so I personally came across this issue when they refused to load rebar on his flatbed until we got a headache rack. Thankfully we found one for $500 on Facebook marketplace years ago.
On highway 31 near where I live, years ago, a roll broke off a truck and punched 3 big holes in the `bridge over the creek and one broke loose on I-65 making many holes in the road. Really glad no car was under them when they went.
Can you make an eight hour version of this video? I can't get enough of this subject.
These coils are what my job uses to make large metal culverts to irrigate water for all sorts of construction. Those coils are dangerous, but necessary for everyday life.
We still make them because they're incredibly useful and convenient. When things go wrong, it's because people screwed up, just like anything else. I worked in metal fabrication for a decade, and any time anything went wrong with coils or flats, it was because the person handling them (often with a forklift,) did something stupid. The steel isn't trying to kill anyone, it's the operator or handler taking shortcuts that get people hurt.
Perhaps if they designed a flatbed type that have wells so the sheets are kinda cradled in place for safer transport. Or some type of chalks large enough to prevent rolling. Idk just ideas off my head
Wow what a genius you are... Just figured out what we already knew for almost 2 centuries
I've hauled those, I was always very careful when securing them. They can kill you easily.
"Cold rolled steel is made from a hot rolled steel sheet."
The coils are not dangerous, it's how you handle them.
Worked milling metals for 5 years, was the lead operator when I got laid off a year ago. A job I miss.
Why not leave it so the inner hole is vertical? You can also add a pole to the truck to hold it
they do that, but not all of them does, it’s also expensive to buy a specific trailer just for that so a lot of people carry them suicide.
Why aren't the crankshafts and gears just splined together from the factory?
They see me rollin.. they hatin..
Not risky if done properly. Not more than radioactive or NLG at least. PLARD: Pack it, load it, attach it, reinforce it, drive carefully.
They should look into transporting these rolls via hot-air balloons.
Yeah let's lift that outrageously heavy hunk of steel way up in the air... so that when there's an accident It comes falling down out of the sky and absolutely flattens anything unfortunate enough to be in its path. What a brilliant idea!! 😂😂
That clip with the steel coil unwinding like that definitely shows just how high the tension is when wrapped up like that. ABSOLUTELY INSANE! 😬
that only happened because the driver forgot to flick the straps, and say that's not going anywhere.
Haha. Only truckers will get this humor. So true. But yea chains required here.
I loaded and unloaded these coils for 10 yrs,You definitely gotta respect the weight! Sied note our coil came straight from China, after processing them i put the made in USA sticker on them😅!
There are more than just steel coils. You have aluminum, copper, and others. Used to make sales drawings for a company that made equipment and full lines for processing them. Some were very elaborate and some very simple.
Why transport them on the round side? Lay them down on the flat side, that way they dont roll.
I worked a coil line for a couple years. 19ga grey Sani steel was horrifying to work with. We wrapped the coils by hand with plastic wrap when not in use. Then, when needed the coil in use again, we would have to cut the plastic with a box cutter and have to literally jump out of the way of the metal unraveling before it slams down against the floor where you previously stood. I’ve had my fair share of almost getting clean clocked by metal.
Hauling coils in that direction is nicknamed a suicide load if you load them longways it's still dangerous because they can roll off the sides but if the chains break in a hard braking situation or a collision it will not send them through the back of the cab of the truck it's also not legal to haul them without a headache rack in the US
It’s the fact that the transporter is not using the right equipment to strap it down or in this situation the semi had an emergency stop. Could have been going to fast, tailgating and not leaving enough room or any other reasons why but still came down to safely strapping the load correctly.
Company i worked for would band huge coils to pallets. Then they would get strapped down dont see that happen alot. But it definitely made it easier when id have to unload them
That first clip was Chuck Norris' toilet paper delivery. He wasnt happy it was delayed.
They’re pretty useful and play a big roll in making tanks for storage. I work in asphalt containment and we build your large tanks by rolling the sheets out with a roller and welding them into shells. We then put those shells together on a large fit up machine and weld them to create the body of the tanks.
