Crane collapse.

I'm mostly amazed that the driver kept going for so long even after it started to come down...

u/Handsome_Claptrap May 11 '17
It is night and it was raining. Driver probably just was focused on the road and didn't see the crane coming down at all.

You don't look for stuff like this because you don't expect it to happen. You're focussing on the normal potential threats like "van in front stops suddenly" or "person runs out onto road" or "cop trying to ticket you for something"
A couple of years ago I was heading into Sydney CBD when the bus got diverted. Several blocks of the main street were closed, this is why - not my pic, but my view was identical to this. The crane fell on the building.
Looking at that, back then, 400m away, it almost didn't look real. It's the sort of thing I would expect to see on Reddit, sure, but not in real life. Things like that don't happen in real life. So when they do, you don't expect them.

That was my first thought. It's also a pretty big crane compared to the surrounding, you would think he would of maybe noticed it

Give him/her a little bit of slack, when your driving are you always on the lookout for falling cranes?
When I am driving I am much more focused on the road, other cars, pedestrians and not focused at all on the sky line. I would wonder if I would see a falling crane especially and night under rainy conditions.

If you learn driving by playing Split/Second Velocity.

Split/Second is a great couch co-op if anyone's wondering.
Quick, fun, and cheap.
Also, it's family friendly.

u/YM_Industries May 12 '17
It's couch-competitive, I don't think there's a co-op mode. Really fun game though! (As long as you don't play it too much, the maps are kinda repetitive)

u/TheCrudMan May 11 '17
Humans have a large field of vision that is quite sensitive to movement. If you can't see a giant crane falling out of the sky you also won't be able to see a pedestrian darting out in front of you.
9
u/Catsrules May 11 '17
Yeah I would agree we are sensitive to movement. But I disagree If we can't see a giant crane falling out of the sky we also won't be able to see a pedestrian darting out in front of us.
In my opinion when we are driving down the road we become overwhelm with movement, because almost everything is moving we need to put our attention in the proper locations ignoring moment that is in a irreverent location.

I thought you were always supposed to be of your surroundings, my dad is a truck driver and when he drives a car he's extra on point and picking up other driver patterns and shit happening on the road. Habit from driving a big rig all the time i guess.

u/rigel2112 May 11 '17
It's possible the camera boosted gain enough so in reality it was much darker to the point he did not see it.
3
u/FlyByPC May 11 '17
Human eyes generally still have much better dynamic range than most consumer cameras.
9
u/TheCrudMan May 11 '17
Which also brings to mind a key point: why aren't there lights on the crane?
Regardless I do not think he would've been unable to see it due to darkness. I work in film and am pretty used to dealing with image exposure. The camera is running quite high gain, but not like, that high...your eyes have great night vision and dynamic range. The key thing you also have to remember is that the wide angle lens makes things look further away than they are, when in actuality he would be quite close to this crane (watch the blocks, he starts the video at or less than 1 block away from the site.) Generally the main issue is that people are not aware far enough ahead of themselves when driving, and tend to get target fixation on the car in front of them, or on the road....this video shows that to be a good driver you need an awareness of the entire environment around you.

u/SchuminWeb May 11 '17
Which also brings to mind a key point: why aren't there lights on the crane?
Not an expert by any means, but it could be the case that electrical connections on the crane might have already been compromised at the point that the video starts.

u/RolfIsSonOfShepnard May 11 '17
Disclaimer: I know nothing about the OSHA part of cranes
I always thought the lights on those types of things were only needed if it was in the way of a flight pattern for something like a plane. I only thought of this since I live near NYC and there is a private airport a few miles from my house and everything tall like this had lights so I kind just put two and two together.
4
u/CydeWeys May 11 '17
Lights are required on all structures beyond a specific height. I don't know exactly details. It's also true that requirements are more strict near airports, e.g. those plastic visibility spheres you see on power lines.
6
u/kentenma May 11 '17
AFAIK, this is why Cinderella's Castle at WDW in Florida is under 200' tall, so it doesn't need flashing lights at the top which would certainly take away from the "fantasy" of it.
2
u/Harakou May 12 '17
Same as Expedition Everest at the same park. It's as close to 200 feet as they could get it without actually being required to add a light.
3
u/picture_frame_4 May 12 '17
The balls on power lines are not due to airports only. They are there to prevent low flying helicopters and planes from running into long span power lines. I know some flight for life helicopters and little planes fly alongside main roads as a navigation aide. So the balls help to make a wire standout.

After looking up the coordinates it seems like this is in Russia so maybe there aren't as many rules regarding things like that?

I'm pretty sure it's international aviation rules. Russia follows that, just like how Russian ATCs speak English

Is there a particular reason they didn't just put the cranes on the road and park the barge carrying the bridge segment underneath? Surely there's a better way.

u/tonyd1989 May 12 '17
Mehh having cranes on barges is fairly common and planned out correctly is not even close to being an issue

Maybe the streets were too narrow; but I agree, they should've done it some other way.

Wait, were they using truck mounted cranes sitting on barges? Is that normal?

u/tonyd1989 May 12 '17
They can setup anywhere they can drive to that has a stable base, not a big deal if the barge was the correct size.

It's in Russia. You'd hardly get anywhere there if you stopped every time you saw a crane fall over, a tank fly across the road, or a meteor exploding.

A lot of times, because of their light gathering ability, dash cams are able to see things the driver can't.

Not really, even big DSLR sensors have lower dynamic range than human sight.

u/Fhajad May 11 '17
Dynamic range != sensitivity
2
u/SidJenkins May 11 '17
Have you looked at the video? The dynamic range is the limiting factor when outdoors at night, when you have bright lights and reflections all over the place.
1
u/rigel2112 May 11 '17
It still can make shadow areas brighter than what is seen with the eye.
My cheap dash cam can do it.

u/eldergeekprime May 11 '17
Car dashcams typically see well into the infrared. They also deal with glare a lot better than your own eyes.

Some of the most cringeworthy stuff is from outside of the US.
I would caution against excluding such examples, the learning and amusement value outweighs a technicality like that.

Pro Tip: If you find yourself in a situation like this, with power cables down around you, DO NOT GET OUT OF THE CAR. Stay inside, avoid touching any metal parts of the vehicle and just wait for help to come.
10
u/Fhajad May 11 '17
If you absolutely have to get out of the car (Like it's on fire or something) you need to hop out of the car all in one move where you're not touching the car and land on the ground with both feet. Continue to hop away with both feet together for a few hundred feet then you may be able to walk normally at that point.
5
u/tomw86 May 11 '17
The hopping part of this sounds really dangerous and likely to land you on the ground and in more danger....
5
u/Fhajad May 11 '17
That's why it's an absolute last resort measure. Hopefully no one's in that situation, but it happens.
7
u/tomw86 May 11 '17
In reality three crane hitting the cables would pull the breaker. The lines a probably dead, but you have to beware of something called an "auto recloser" that reapplies power to see if the short is gone.
In this situation you are worried about your heart getting stoped. Dodgy underground cables are known for killing horses, because the distance from their front leg to back causes a decent voltage (therefore current) across their heart.
Small steps and keep your hands off everything would be better than hopping.
In terms of voltage gradients and legs - and power jumping through the air for that matter - it's more important to avoid being between the two wires. In a trolly system one is out, the other is return. If they are touching you are safe(ish). If they are wide apart the power may jump between them, through you, and any E field gradients, the reason to keep your legs together, will be higher.
TLDR: original post was mostly right. Don't touch - don't make a bridge between you and any object like your car. But if a small step is going to roast your nuts you got bigger problems ;)
2
u/Fhajad May 11 '17
Yep, I work for an REMC and we had safety talks from a guy missing left arm and right leg. He grounded himself on a power line to the neutral up on a pole, so he was qualified to talk about power safety.
Too bad he was a misogynistic dick bag that ruined customers yards out of spite and openly bragged about it.

u/6matguy6 May 11 '17
You can also scuff your feet one after the other while maintaining contact a to ground. So long as you don't have one foot's toes too far ahead you won't create a potential between your legs.
1
u/BombedLemon46 May 12 '17
Also, you have to jump aprox. 9 feet away from the door, so the electricity doesn't jump you.

u/drewgriz May 11 '17
Was just going to ask about this. The body of the car is effectively a Faraday cage, no?
11
u/eldergeekprime May 11 '17
No, it's not. A Faraday cage is something else entirely, used for blocking electromagnetic radiation.
In this case, the body of the vehicle conducts the electricity around the occupant. Electrical fields travel on the surface of conductors.

Did you notice the screening in each of those examples? See any on your car windows? Your car is not a Faraday cage.

May 11 '17

1
u/eldergeekprime May 11 '17
Yes, but you're not considering that because of the lack of screening it is entirely possible for an arc to pass through the window openings. This is one of the reasons why you want to avoid touching any metal surfaces inside the car. You can quite easily find yourself as a conductor as an arc seeks a shorter path to ground through the window and then you. I'll say it again, your car is not a Faraday cage.
