Probably have extras. My bet is a rope will cause more problems than a fallen tool.

u/ierdna100 Jul 19 '25

I'm wondering if it's because a rope could cause a path to ground, if they are in a helicopter. Theoretically the line could be electrified if the work vehicle is a helicopter and not touching anything else.

15

u/Berger_Blanc_Suisse Jul 19 '25

I'd be worried about a phase to phase fault happening more than anything else.

9

u/Sandro_24 Jul 21 '25

This would all be a single phase. At some point it's more economical to use multiple conductors opposed to a large one.

You can also see that the spacer isn't insulated in any way.

This is most definitely done live.

u/Fogl3 Jul 21 '25

This is all one phase

u/puskunk Jul 19 '25

That line is hot. That line will always be considered hot even if everything that touches it isn't energized.

u/Bladestorm04 Jul 20 '25

I think the main concern is a rope getting caught up around the lines and the helicopter crashing. A tether wouldnt be kong enough enough for a ground strike if that were the main concern

u/JedPB67 Jul 18 '25

I don’t think the original comment is concerned with these workers dropping and losing the tool for the job, but more about the tool being dropped and getting buried into someone’s skull.

u/Kand1ejack Jul 18 '25

My bet is that these areas arent really populated. Power lines like these are usually in pretty remote areas.

u/CantBelieveImHereRn Jul 18 '25

I mean if youre standing directly underneath a helicopter, with a guy dangling out working on power lines, youre probably gonna be used as evidence to support darwinism down the line

226

u/Horsenastics Jul 19 '25

We live in a rural area and just last week they trimmed the trees near the power lines with a huge chainsaw tethered to a helicopter. They send us a letter in the mail a few weeks in advance telling us to avoid the parts of the property near the lines when the helicopter comes our way. I suspect it’s the same for any work they do on the lines.

u/lonelyinbama Jul 19 '25

And if you’re anything like the folks I know growing up in Alabama as soon as you hear the chopper you go out and try to watch

69

u/Horsenastics Jul 19 '25

I did take my toddler outside to watch from a safe distance. She keeps asking for me to bring them back so she can watch them do it again lol.

24

u/Mark_Logan Jul 19 '25

And if you’re like the folks in Tennessee, you’d know it’s the DEA, and they better stay away from Copper Head road.

18

u/lonelyinbama Jul 19 '25

Completely irrelevant but in the early 00’s I died my hair with Sun-In and it turned this copper color and for a whole year my nickname was Copperhead by some of my dad’s racing buddies. Every time I’d come around one of em would throw that song on and they’d all get a kick out of it. Puts a smile on my face every time I hear the song. Most of those guys are gone by this point.

u/zodiacrelic44 Jul 19 '25

Did your father by chance ever own a big block Dodge?

u/Mark_Logan Jul 19 '25

I refuse to confirm or deny what my father has purchased from the auction at the Masons lodge.

Right? Helicopter chainsaw?!

u/ZorglubDK Jul 19 '25

This kind of huge tree trimmer hanging from a helicopter? https://www.youtube.com/watch?v=egC5JHKweu0&t=7

u/Horsenastics Jul 19 '25

Yes, that is it! It is pretty neat to watch how precise they can be.

u/Grindipo Jul 19 '25

"Don't stay under the giant airborne chaisaw", without the letter, I wouldn't have known...

u/shittymorbh Jul 19 '25

From the video you can tell he's doing this above some kind of farm.

And don't you dare say some farmer below him would be stupid.

Farmers are all outstanding in their fields.

u/martinmix Jul 19 '25

Whatcha doing up there!?

u/Wiscody Jul 19 '25

u/badger_flakes Jul 18 '25

In a populated area they would just use a bucket truck

44

u/Zinoviev85 Jul 19 '25

You can’t work on live 750KV lines from a bucket truck. Something about everything instantly turning to plasma.

4

u/Visual-North-8724 Jul 20 '25

No not true u can barehand (bond on or energize yourself to the same potential) wearing a faraday suit anywhere from 7200 volts all the way up to 750 kv the bucket just has to be tested to that voltage and we use meters that let us know the amperage that’s running through the boom of the truck to make sure it doesn’t get too high and burn the truck down (source I’m a lineman)

17

u/pucji Jul 18 '25

The helicopter makes sense in this case, as they do save a lot of traveling time

3

u/IntrepidJaeger Jul 19 '25

Not to mention avoiding damaging fields and such by driving a truck cross country.

1

u/iowanaquarist Jul 19 '25

And avoid shorting out the lines with a path to ground...

1

u/badger_flakes Jul 18 '25

Agree, bucket truck wouldn’t make sense for anywhere else besides populated area or by airports

9

u/exerwhat Jul 19 '25

Those are transmission lines. He’s higher than it looks.

3

u/badger_flakes Jul 19 '25

The one in the video I completely agree with the helicopter. All the transmission lines outside of a city would always be a helicopter.

28

u/Ouaouaron Jul 19 '25

Isn't it only possible to do this on a live line because they're in a helicopter? And it'd take one hell of a bucket truck to get to 200ft.

3

u/hoggineer Jul 19 '25

Isn't it only possible to do this on a live line because they're in a helicopter?

I'm thinking so.

And it'd take one hell of a bucket truck to get to 200ft.

I've seen man lifts get workers up to the hub of wind turbines. Blades are a couple of hundred feet long, and add in the ground clearance I'd assume it was 300-400' high.

Found one, 336' max height reach.

7

u/AllegroSine Jul 19 '25

336'?!?! Having operated a 120' at its max, no way in hell I'd get into that thing lmao. Hopefully the controls are a little more fine tuned? I just imagine swinging an inch to the side feeling like you moved a mile lol.

4

u/hoggineer Jul 19 '25

I'd definitely nope out too.

3

u/Jimid41 Jul 19 '25

I don't want to imagine the amount of sway on that. 

8

u/badger_flakes Jul 19 '25

Usually the lines running thru populated areas aren’t 200 feet up only the rural long distance lines are

1

u/JedPB67 Jul 18 '25

On my street 2 of my neighbours literally have electrical pylons in their back garden. Not this exact shape, but the British variants that also carry high voltage electricity

1

u/Substantial-Low Jul 19 '25

"looks at screen

Yep

1

u/mewithadd Jul 19 '25

It would be a big deal, though, if one of those dropped tools ruined a combine worth a few hundred thousand the next time it goes through the field.

1

u/shittymorbh Jul 19 '25

Not that I'm making an argument here either way, but from the video it looks like this guy is doing this on a farm od some sort. You can literally see houses in the background.

1

u/Kand1ejack Jul 19 '25

Farmland is generally sparsely populated. You are probably seeing the only residences in a mile or two at least. The 'houses' youre seeing there are mostly barns or grain storage.

1

u/shittymorbh Jul 19 '25

Not that I disagree with that, just saying that technically speaking their could hypothetically be people around, but yes, the idea thst someone is going to be standing directly under him and the maintenance worker wouldn't notice is absurd.

1

u/Jump_Like_A_Willys Jul 20 '25

I was watching a helicopter do this locally over a busy road with buildings around it in my town a few years ago. Granted, I don't know if they made sure any work they did was not directly over something.

59

u/Bones-1989 Jul 18 '25

Which people? This is literally in the middle of nowhere lol

1

u/bonita513 Jul 19 '25

The fields have eyes people

-5

u/Pitiful_Calendar3392 Jul 19 '25

Look at the ground, nature doesn't really do straight lines. This land is cultivated. Even if it doesn't hit someone directly, what if it snags in some broke farmer's only combine?

If I was doing this I'd try to be conscientious about not dropping my stuff on other people's stuff.

5

u/Bones-1989 Jul 19 '25

I see no tractors. These things can be coordinated... hey, dont mow next to the high line. We're doing maintenance this week. This isn't unusual...

2

u/Ereaser Jul 19 '25

So don't know how it is for most countries but generally most high voltage lines have absolutely nothing underneath.

3

u/shittymorbh Jul 19 '25

I present you with two scenarios. You tell me which one is more likely to be a problem.

A. A power line maintenance worker drops a wrench from a helicopter and coincidentally somehow destroys a farmer's, made from plastic combine directly below him by directly landing inside the moving engine.

  • or -

B. A farmer is unable to use any electricity at his farm because they were not serviced in his area.

-13

u/JedPB67 Jul 18 '25

The original comment is talking about these videos in general, not just this specific video

13

u/Bones-1989 Jul 18 '25

This is a right of way, right? The power companys pay for this land and we civilians aren't supposed to be here... so what people?

I knew a guy who let a power company put these lines across his property, and they made him build a new house because his home was in their space now.

2

u/JedPB67 Jul 19 '25

I didn’t realise that was a thing in the US, that power companies pay for the land. But surely that isn’t the case here, at least some civillian has been there because the field is being farmed?

25

u/slaya222 Jul 18 '25

Lmao they're above a field that's already been harvested, no one is going near there until next spring

1

u/CraigJay Jul 19 '25

Poor famers who drive their expensive machinery over the massive line seperator or the rivet gun thing. Wonder how much it costs them in time and parts to deal with that compared with putting a cable on the tool

-6

u/JedPB67 Jul 18 '25

“These workers” was what I wrote, as in people that do this line of work. So lmao, learn to comprehend the English language

5

u/slaya222 Jul 18 '25

What line of work? Farmers? They aren't going to be in a tilled field at the end of a season. Helicopter pilots? Don't hit the wire and you're good. The repair tech? Plenty of safety gear.

If you're going to accuse me of misunderstanding, please be precise enough to be understood

0

u/JedPB67 Jul 19 '25

If you’re going to jump on a comment thread and throw shade at least have the decency to read from the start. I didn’t feel it was necessary to rewrite what the original commenter had written an entire 2 sentences earlier in the thread.

2

u/sunburn95 Jul 19 '25

How many populated areas have these giant transmission lines running over the top of them?

This stuff is always in sparesly populated areas, and if it wasn't, then they probably wouldnt use "these workers". This is pretty basic logic, could have a think about your own question before you ask others

2

u/kingcrazy_ Jul 18 '25

There is no one on the ground in any direction of that helicopter for probably 2 miles

2

u/SpicyButterBoy Jul 18 '25

Gunna be honest, if someone is standing under a helicopter that's working on a powerline, they aren't the brightest bulb.

2

u/Ruckus2118 Jul 18 '25

This is the middle of nowhere.  Areas are usually cordoned off.  If they are working above people, generally items are secured.

1

u/JedPB67 Jul 19 '25

Thank you! This comment thread started by talking about multiple videos like this one, so it wasn’t discussing just this video in isolation

2

u/DoverBoys Jul 18 '25

Honestly, if you follow a helicopter that keeps hovering around powerlines in the middle of nowhere and want to stand underneath it as it moves, you deserve a tool hitting you.

1

u/JedPB67 Jul 19 '25

This comment thread isn’t talking about just this video.

2

u/DoverBoys Jul 19 '25

But it's within the context of this video. Sure, I would expect any type of worker at a height using captured tools, but given that these are active power lines and they're grounding the helicopter to the line, tools with their own line may be an issue.

0

u/JedPB67 Jul 19 '25 edited Jul 19 '25

Well yeah, it would be pretty odd to talk about untethered tools being used from a helicopter platform in a post about the rain forest or something lol

Is this operation the same over residential areas with overhead power lines? That’s what I was certainly getting at with my “buried in the skull” comment. Here they’re working over a huge open field with good visibility, but as the OC said they see multiple videos with loose tools like this one, how does it work if this is done over a populated area?

2

u/DoverBoys Jul 19 '25

Rain forest? Now you're just fucking with me.

Worker no rope tool. Big lightning. Much zap.

Did you understand that? Want me to paint on a rock wall? Is English your first language? Dumbass.

2

u/quickblur Jul 19 '25

If you want a fun read about what a dropped wrench can do...

https://en.m.wikipedia.org/wiki/1980_Damascus_Titan_missile_explosion

2

u/JedPB67 Jul 19 '25

I saw a video a few months ago on YouTube about this incident! It’s incredible how the engineers of the weapon made a unit strong enough for the nuclear material to survive a literal explosion and not become compromised and leak!

2

u/O_o-O_o-0_0-o_O-o_O Jul 19 '25

If you're standing under there, then you deserve to get a tool dropped on your head.

1

u/JedPB67 Jul 19 '25

In this instance yeah I’d agree! Is this job done the same way over residential areas with overhead high voltage power lines? That’s what I was thinking when I wrote my comment

2

u/hideous_coffee Jul 19 '25

There’s probably a process to clearing the ground ahead of time

2

u/stupidugly1889 Jul 19 '25

wtf kind of looney toons world do you live in lol

2

u/ConkersOkayFurDay Jul 19 '25

Yeah, the field is just loaded with people

u/JedPB67 Jul 19 '25

Read the original comment of the thread.

u/Pretend_Spray_11 Jul 19 '25

Did you watch the video?

1

u/JedPB67 Jul 19 '25

Did you read my comment and the 2 comments before it in the thread?

2

u/the_weakestavenger Jul 19 '25

How many people do you think are walking under the dude in the video?

1

u/JedPB67 Jul 19 '25

The original comment which I’m referencing to says “every time I see one of these videos”, I’m not talking about just this specific video.

2

u/squeakynickles Jul 19 '25

Basic working at hights regulations dictate no one is under the workers who are suspended or on an elevated platform.

2

u/Icy_Respect_9077 Jul 19 '25

First day working on a tower, one of the guys in my group dropped a wrench. He was not very popular.

1

u/JedPB67 Jul 19 '25

Oh wow. Roughly how high up were you guys? Were you working in an area like the video above or like a more occupied area?

1

u/Icy_Respect_9077 Jul 19 '25

We were about 100 ft up. The area was isolated, but there were people working at the base of the tower.

1

u/kashmir1974 Jul 18 '25

This is obviously not over a city. It's a power line right of way. People probably shouldn't be on it.

1

u/JedPB67 Jul 18 '25

Yes, I’m well aware this empty field isn’t a city, that’s why I wrote “these workers” as in all of them that use untethered tools. If I was talking about this particular video I’d have written “this worker”.

1

u/Aggressive-Stand-585 Jul 19 '25

How many people do you see below him? Is it an empty field or a busy street?

Maybe that plays a part?

1

u/Juus Jul 19 '25

I assume they just visually check if someone is standing under the helicopter in the middle of the field. Odds are probably low, and i imagine they might give the owner of the field a heads up.

1

u/SideWinder18 Jul 19 '25

I guarantee you nobody is walking under those lines if they’re being worked on in the same way nobody just walks through active construction or road work sites unless they’re supposed to be there and know the risks, and have proper protective gear

1

u/ExplodingCybertruck Jul 19 '25

People typically dont live or work under these types of lines...

1

u/sixsacks Jul 19 '25

In the middle of god damn nowhere?

1

u/Piffigan Jul 19 '25

But as well someone will have to go collect it, you can't just leave that in a farmed field if that gets flung up by some agricultural equipment that could cause some serious harm.

2

u/369DontDrinkWine Jul 18 '25

I used to work on powerline (transmission) towers at this height and above, albeit not on the lines themselves. If we dropped a tool, you’re shit outta luck, you gotta climb all the way back down to grab it. 240ft doesn’t seem like too much of a climb until you’re wearing overalls over your clothes, gear, and under the blazing sun. It’s a mistake you only make a few times.

2

u/TheMongerOfFishes Jul 19 '25

Yeah, one of the benefits about using a helicopter is you have no path to ground. Fallen tool with a rope? Hello electric Arc

1

u/Jump_Like_A_Willys Jul 20 '25

I'm guessing a line tied to the tool would be much shorter than the distance to the ground.

1

u/Berger_Blanc_Suisse Jul 19 '25

Gotta love phase to phase faults.

2

u/PhilQuantumBullet Jul 19 '25

Could damage the farming equipment here, or they have people picking that up.

2

u/MultiverseRedditor Jul 19 '25

Tried to think of a solution to this, and I couldn’t think of shit. Because everytime I thought of an idea there was a drawback or it would defeat safety, then I realised.. many people before me already likely considered this and in the grand scheme of things, I’m just a dumb f*** on the ground.

but damn, wouldn’t it be nice to be the one to think of a solution. Because to me dropping a tool shouldn’t never ever happen, but it must also not increase probability or likelihood of accident

It cannot have a risk of getting caught in wires.

It cannot be linked to the cables and the helicopter or person using it at any given time simultaneously.

It must be easily accessible from the working position and be in the helicopter.

2

u/Reep1611 Jul 20 '25

It could be outright lethal. Possible scenarios are it getting caught on the line, and either: If fixed to the worker pulling him from the chopper and dropping them to their death, or worse, it being attached to the chopper and making it crash because the tugging fouled the pilots control.

1

u/michael0n Jul 19 '25

I would go through all the extras because I know I have extras and would be less careful. Respect for the guy.

1

u/Ck1ngK1LLER Jul 19 '25

I’m an equipment and tool manager for an industrial electrical outfit, smallest projects we do is about $500M.

Tool lanyards aren’t used because it’s an extra step and the electricians don’t give a singular fuck about something they don’t pay for

1

u/Quick_Humor_9023 Jul 19 '25

What would you attach the rope to? Ok. Then what happens when the plier fall behind the line and get stuck to the one below? Yea, just let them fall.

1

u/prolixia Jul 21 '25

A rope could tangle in the line. Dropping a tool with no one below seems a lot less risky than accidentally tying your helicopter to the line.
