@DJGahann Well they quite often do not shut the electricity off at all, inconveniencing hundreds if not thousands of paying customers is not in their best interest.
@gailgrove a truck under high voltage and you don't see danger, ok.. Cutting power maintaining life, as I think you're implying, can and should not be fatal as those facilities will always have a means of backup.
i kicked a powerpole and it rattled a tree hangging by a thread,the tree fell taking the powerpole with it..the tree was 50ft it took out a mailbox and some line and the weirdest thing was i didn't even kick hard,i was knocking mud off my boots and it came down,that was the weirdest fucked up thing i've seen in a while the wind was strong today it blew a bunch of trees down so i guess i was just there at the best/worst time. it was kinda funny,it was today.i wish i had a camera,damn! XP
Electrical lines will strike down the "un crane worthy". Man that was just stupid. Here's a clue...regardless of the techie shit....stay the fuck away from powerlines cause they will fry shit up. And for those gung ho foreman who have their head so far up the bosses ass that they can taste what they had for lunch......I won't get just a little closer to energized lines so you either suck my pathetic little dick or fire me.
@kengine7 no its not, earth is neutral with respect to live so any contact is a dead short, ie it does not have a loading resistance to reduce current flow
@TheMrBlinx but potential difference is the differential between the energy available between the phase and the star point/earth/neautral on thesupply transformer secondary coil.
this is high voltage discharge, dry sand is at a low enough potential to easily allow conduction with this level of voltage, even the air which is the best insulator next to a vacuum is ionising allowing large and noisey arcs to form.
Was Mr. "Don't watch that" speaking to the camera man? If so, he was wrong. That camera screen can NOT reproduce light of the intensity required to hurt or blind anyone.
What would happened when this power line would had falled over on the street after a pole would being hit by a car? I doubt that the safety systems (fuses and so on) would had then worked well. There are enough examples of power line threads hitting the ground and still standing under current even several minutes later!
What I'm wondering here is, are there any safety installations on that power line? Because of the outriggerns and nearly everything else on the truck being out of metal must be a low resistance to the ground. But there is still current running thru the truck even after several minutes. This can be either: complete lack of any safety systems (which was quite common on older US electric installations) or the safety systems was faulty or not working.
@Seravajan Too much resistance to trip OCB's (Oil Circuit Breakers). It was like a large resistor. If it were a dead short (to ground), it would have tripped out and reset two or three times (usually three) and then stayed off. But, when it's not a dead short, the power remains on, no matter what protection they have.
hey mr harry 46, do you know the ampacity of the cutouts upstream from the point of contact, if its a busy aera they could be as high as 500 amps, which is definatly more than was grounding out through the crane. this is a prime example of the new requirements in the 2008 edition of nfpa 72 requiring arc fault ocpd's or breakers in dwellings, although the tecnology does not yet exsist for distribution systems, we are on the way. if you dont know what you are talking about, dont comment!!!
does anyone see a reason why he should have that much boom out? doesn't look like anything there has to go that high does it? and it didn't reach away very far out b4 it hit the power lines. ouch!!
WOW the operator hopefully survived, Don't just stand there and watch, start doucing it with water.... !!! Duh Now just sit back and watch all the fluoride drinkerz attack.
Surely they have some sort of mechanism to stop people getting hurt if this happens? I mean why dont they just line the floors in the crane with rubber or something. That way there would be less change of that hurting anyone and they could stay there until they switch the power off...
When the winch cable first hit and everyone knew something not good happened, did they go: "Haw haw haw haw, whoo-hoo!! Har har har har! You fucked up!! Umm, have a problem there son? Sorry, we can't help you. Well, we're outa here you're on your own dude".
It's easy to say why didn't the operator look up but there are companies that don't let you take time to be careful. Get the job done don't waste time checking is their mentality-Fucked Up but they're out there.
there would be gradient voltage around the crane. the network would have seen it as a load on one phase thats why it took so long to trip. at the end the circuit breaker tripped then reset it self i think it does that 3 times before completely shutting down
No shit... I was trying to figure out were the line was touching it, but then I saw the cable. Aren't power lines like INSULATED? Jeez. I hope everyone was okay. That could turn nasty. So THAT'S why they plaster equiptment and ladders with all those warnings about power lines! I get it now....LOL.
Some newer high voltage conducters(powerlines) we install in high bushfire risk areas are insulated, but most are bare wire. Theyre insulated from earth by the air, which isnt much good if you drive a crane into them..
In Europe high voltage lines are insulated but in the USA we use bare aluminum because its a lot cheaper. The USA is a lot larger and stringing cables further costs a ton of cash
i hate that electrical buzzing sound. i was woken up to the start of an electrical fire and thats how it sounded. we got it put out though the wall above the outlet was burnt to a crisp!
forget the cost of delay and the cost of the truck, the operator would have been lucky to live if he was operating the truck manualy (some times are remote controled) and the boom would have seized when it contacted. all the hydrolics have electrical solonoids, they would have been damaged , the company probably got sued by the electrical provider for damaging the system, some can charge milions per day, due to lost customer revinue
"forget the cost of delay and the cost of the truck"
Truck would have been insured like any other vehicle or business assett.
A Canadian OSHA type video here in Youtube shows what to do if this happens and you are inside the cab.
You jump clear and clean of the vehicle and keeping your feet together jump forward and away from the immediate area by "bunny hopping" for lack of a better word.
If you walk and the ground is energized nearby, you can be shocked- each leg acting as a conductor.
I'm curious: why didn't the crane operator simply move the boom away, once he realized he'd contacted a line? (Unless the juice fried the boom controls, of course.) Would have saved the truck from burning to the ground, would have saved the electric company (and its customers) down time, and would have saved the construction company thousands of dollars in delays.
because it is too late wen you hit a power line like that then all of the fuses are toasted. and almost all of the old power lines have no insulation around the wire. (power lines above the ground)
@watchdog68 basically, hydraulic valves are in some case solenoid operated, and heavy machinery like this uses "break valves" that automatically lock the charge in place in case of accident, and finally, welding is using heat of an electrical arc to make a fusion between 2 pieces of steel.... hydraulic valves are made of steel... maybe that will answer your question ;)
@usedcow4sale Thanks, but I don't remember asking a question. If memory serves me correctly, I think I was trying to answer someone else's question, but could only give a "best guess" as to what happened.
@lonewolfintj as uncaljeff said: hydraulic machinery usually uses solenoïd operated valves so shorting a power line to the ground also mean shorting any equipements in/on the machinery including solenoids (wich are electro-magnets to operate valves)
@GREENVK forget about tires as insulators. If the electricity can arc 4 inches to the crane, it can also arc 4 inches from the crane to the ground. So never trust that your tires will save you.
Mr. Jim-Bob: [sarcasm]Duee yuo notace taht wehn yuo missspelll aa warde, YouTueb putts a redd underlien undar itt? Doo yuo knwo whatt taht maens?[/sarcasm] It means you should right-click the word and correct it's spelling. It took me a while to figure out that by "tyer", you actually meant "tyre" (British spelling?), or maybe even "tire". If your spelling errors are too severe, no one will understand what you meant. Spell checking is a good way to prevent that problem.
Delana Rockz: I'm guessing that what you really meant was: "Stupid! It was touching the three lines! That was more than 5000 volts making contact with the ground!" Ok, firstly, no, it wasn't touching more than 1 phase at once, or the line fuses would have blown. And secondly, proper capitalization, punctuation, and spelling would make your writing much easier to understand. Those things being said, though, your statement is essentially correct. Yep, the truck driver did a stupid thing.
@delenarockz by touching the 3 lines at the same time, that would make a huge electrical explosion, assuming each of the 3 phases are "dephased" by 120 degrees so they aren't "synchronized" and shorting 2 phases together is similar to putting one of them directly to the mass (ground).
@delenarockz Sorry for my poor english, i'm an industrial electrician and i usually have to connect 3 phases motors. Connecting line one (L1) to the wire T1 of the motor, L2 to T2 and L3 to T3, we get a motor that rotate forward, to make it reverse we simply invert 2 phases, usually L1 to T3, L2 to T2 and L3 to T1 so doing it need a careful attention, we use 2 contactors (Forward/Reverse) and we put an "mechanical interlock" between them to prevent phases beeing shorted together ;)
@usedcow4sale Things like you mention are why I will not be an electrician or lineman. Even if I'm careful colleagues can make mistakes or equipment can be faulty-BOOM! I'll stick with low voltages and instrumentation.
@usedcow4sale Yes can we say Arc Flash. 480 volts makes nice explosions. Actually shorting a phase to ground is shorting 277 volts (with 480 phase to phase). Still pretty violent. I've had a 277 volt indicator lamp short and even that makes a nice POW!
@Nivicoman yeah i know... i saw someone (maybe a little dumb) shorting two phases of an 600 volts phase-to-phase input wich is 347 volts line voltage.... nice to see but a bit scary ^^
i don't see what the guy was trying to pick up. i'm assuming the guy had already dropped the load and was swinging the boom back to the rack. imagine his surprise! i'm surprised they didn't stop traffic. all that has to happen is the hydraulic fluid to boil off and that whole boom would fall across all the wires.......BOOM!!
Just getting close to the truck would kill you there is step potential in the ground there. If you wanna get close better scoot you feet on the ground.
I got to see this on tape in my training course. At 2:57 you see an outrigger jack completely melted away. It's not really clear in this video, but on tape, it's clear, that thing is gone.
In this type of accident, the non-insulated boom has obviously contacted the power line, the gas tank on the vehicle explodes...somebody is in big trouble...federal minimum approach to the power lines is ten feet.
The ground all around the truck eventually became energized, so forget about saving anyone or anybody. Call the power company, keep everyone away, don't be a dead hero.
@justinaurelius No, not corona. Current is flowing through the steel lift lines, down the boom, through the truck body and to the jackstands. That much is pretty low resistance. But the ground around the truck is fairly high resistance so as current flows through it a voltage drop is produced. Just standing with two feet separated along the current path in the ground could run a good amount of current up one leg and down the other.
Voltage refers to the potential energy of the electrons flowing through a circuit (Speed)
in laymans terms, amperage refers to the number of electrons flowing through a circuit. No matter at what voltage, 5mA (0.05 amps) is enough to stop the heart. 6 mA can kill you, no matter the voltage. Why can you touch your tongue to a 9-volt? Nowhere near enough potential energy. Short a teakettle and try it. You'll fly across the room, if you're lucky.
The 12 volt battery is taking a short path across 2 points on your tounge from the negative to posative side of the battery. It is not passing through your heart. Your skin provides a good deal of resistance to a 120 volt shock, causing the current flow to be lower. There are a lot of variables that go into how dangerous a shock can be.
a dump truck driver near here hit a line with his bed up, was fine until he tried to jumped out and fell back against the truck. wielded him tight to it
So if you stayed in the truck would you get electrocuted? or would the electricity flow through the truck around you? I dont know much about electricity, It really scares me, but I always wanted to know if you would be killed by staying in the truck
No You will become the same votage just like a bird on a wire All it does is find a ground. better to stay put until help gets there. or jump as far as you can with both feet landing at the same time and hop out of its path
The electricity would flow through the truck body around you. You would be save as a bird on a wire. However if you were to try to get out, you would become the path to ground and the electricity would flow through you, killing you. You would have to jump clear a distance of more than 12 feet. Not easy. So stay put until you are rescued.
not true, step potential. meaning when you jump you would have to keep your feet together. if you separated them the difference in potential between your feet would cause a current flow. you can jump just keep the feet together. staying inside is lunacy the arcing across the metal of the car would cook you.
no retard the truck is grounding the power lines. you're thinking about jumping on power lines without grounding yourself, but the truck is grounded and is conducting electricity. you would die.
You're also wrong. Electricity goes through the easiest route, Steel and aluminium are much less resistive than flesh and bone. You'd get a punch from touching the truck and being grounded, but it wouldn't be the full hit.
That half-amp (Asuming there is the required voltage) would have to travel Though the body, i.e. go from one arm to your leg. Standing on a truck is not completing or bypassing any circuit and therefore no current is flowing through the body.
how would a ground on the truck keep someone from getting the boom into power lines? its still a path to ground just not as good path, more restance so more current is drawn
If you think you might be too close to a powerline you probably are.

It took me a while to figure out that by "tyer", you actually meant "tyre" (British spelling?), or maybe even "tire". If your spelling errors are too severe, no one will understand what you meant. Spell checking is a good way to prevent that problem.

Delana Rockz: I'm guessing that what you really meant was: "Stupid! It was touching the three lines! That was more than 5000 volts making contact with the ground!" Ok, firstly, no, it wasn't touching more than 1 phase at once, or the line fuses would have blown. And secondly, proper capitalization, punctuation, and spelling would make your writing much easier to understand. Those things being said, though, your statement is essentially correct. Yep, the truck driver did a stupid thing.
lonewolfintj 1 year ago
@delenarockz by touching the 3 lines at the same time, that would make a huge electrical explosion, assuming each of the 3 phases are "dephased" by 120 degrees so they aren't "synchronized" and shorting 2 phases together is similar to putting one of them directly to the mass (ground).
usedcow4sale 1 year ago
@delenarockz Sorry for my poor english, i'm an industrial electrician and i usually have to connect 3 phases motors. Connecting line one (L1) to the wire T1 of the motor, L2 to T2 and L3 to T3, we get a motor that rotate forward, to make it reverse we simply invert 2 phases, usually L1 to T3, L2 to T2 and L3 to T1 so doing it need a careful attention, we use 2 contactors (Forward/Reverse) and we put an "mechanical interlock" between them to prevent phases beeing shorted together ;)

@usedcow4sale Things like you mention are why I will not be an electrician or lineman. Even if I'm careful colleagues can make mistakes or equipment can be faulty-BOOM! I'll stick with low voltages and instrumentation.
Nivicoman 1 year ago
@usedcow4sale Yes can we say Arc Flash. 480 volts makes nice explosions. Actually shorting a phase to ground is shorting 277 volts (with 480 phase to phase). Still pretty violent. I've had a 277 volt indicator lamp short and even that makes a nice POW!
Nivicoman 1 year ago
@Nivicoman yeah i know... i saw someone (maybe a little dumb) shorting two phases of an 600 volts phase-to-phase input wich is 347 volts line voltage.... nice to see but a bit scary ^^

i don't see what the guy was trying to pick up. i'm assuming the guy had already dropped the load and was swinging the boom back to the rack. imagine his surprise! i'm surprised they didn't stop traffic. all that has to happen is the hydraulic fluid to boil off and that whole boom would fall across all the wires.......BOOM!!

mackjsm 2 years ago
In this type of accident, the non-insulated boom has obviously contacted the power line, the gas tank on the vehicle explodes...somebody is in big trouble...federal minimum approach to the power lines is ten feet.
The ground all around the truck eventually became energized, so forget about saving anyone or anybody. Call the power company, keep everyone away, don't be a dead hero.
Backyard76 2 years ago
That ten foot limit is due to corona discharge, right?
justinaurelius 2 years ago
Probably. And also I'm surprised the engine didn't explode.
krabykevin 2 years ago
@justinaurelius No, not corona. Current is flowing through the steel lift lines, down the boom, through the truck body and to the jackstands. That much is pretty low resistance. But the ground around the truck is fairly high resistance so as current flows through it a voltage drop is produced. Just standing with two feet separated along the current path in the ground could run a good amount of current up one leg and down the other.

Thunderbolt1000T i got shocked with 230VAC and i'm still here, and i even know someone who survived a 900VDC arch. To get killed you need two things:
First one is the current has to go through your heart (it will not always do it)
Second one: your body has to be exposed to a current over 0.5Amps
Renard380 2 years ago

Voltage refers to the potential energy of the electrons flowing through a circuit (Speed)
in laymans terms, amperage refers to the number of electrons flowing through a circuit. No matter at what voltage, 5mA (0.05 amps) is enough to stop the heart. 6 mA can kill you, no matter the voltage. Why can you touch your tongue to a 9-volt? Nowhere near enough potential energy. Short a teakettle and try it. You'll fly across the room, if you're lucky.

Gerrit22041992 2 years ago
you cant have 0,5A flowing through your body at a few millivolts ... your body has 1kOhm resistance
6mA can be deadly
Cryptoz4 2 years ago
The 12 volt battery is taking a short path across 2 points on your tounge from the negative to posative side of the battery. It is not passing through your heart. Your skin provides a good deal of resistance to a 120 volt shock, causing the current flow to be lower. There are a lot of variables that go into how dangerous a shock can be.

So if you stayed in the truck would you get electrocuted? or would the electricity flow through the truck around you? I dont know much about electricity, It really scares me, but I always wanted to know if you would be killed by staying in the truck
animallover017 2 years ago
No You will become the same votage just like a bird on a wire All it does is find a ground. better to stay put until help gets there. or jump as far as you can with both feet landing at the same time and hop out of its path
hotrodpc383 2 years ago
The electricity would flow through the truck body around you. You would be save as a bird on a wire. However if you were to try to get out, you would become the path to ground and the electricity would flow through you, killing you. You would have to jump clear a distance of more than 12 feet. Not easy. So stay put until you are rescued.
kb7rut 2 years ago
...unless the vehicle catches fire...
Renard380 2 years ago
not true, step potential. meaning when you jump you would have to keep your feet together. if you separated them the difference in potential between your feet would cause a current flow. you can jump just keep the feet together. staying inside is lunacy the arcing across the metal of the car would cook you.

no retard the truck is grounding the power lines. you're thinking about jumping on power lines without grounding yourself, but the truck is grounded and is conducting electricity. you would die.
crookednoseisfine 2 years ago
You're also wrong. Electricity goes through the easiest route, Steel and aluminium are much less resistive than flesh and bone. You'd get a punch from touching the truck and being grounded, but it wouldn't be the full hit.
FacialTurd 2 years ago
i'm not exactly sure how that makes me wrong. only takes half an amp to stop your heart
crookednoseisfine 2 years ago
That half-amp (Asuming there is the required voltage) would have to travel Though the body, i.e. go from one arm to your leg. Standing on a truck is not completing or bypassing any circuit and therefore no current is flowing through the body.
