- Here are some more details about it:
This machine weighs 580 Tons, 91.8 meters long, 7.4 meters in width, and 9 meters in height. She is able to lift 900 tons of stuff.
Made by the Beijing Wowjoint Machinery Company: www.wowjoint.com/
Here are some more details:
1, The main support leg adopts the joint-dominated triangular structure. The supporting wheel train 〖JP3〗mechanism is used on the main support leg. Without any anchor measures, the main support leg is designed to realize the structure self-〖JP〗stabilization and can resist overturning moment which bridge erecting machine over the span to the next pier.
2, With the constant drive mode on the main support leg, the bridge erecting machine realizes the synchronization control mode of different driving methods and improves the safety and reliability in operation.
3, Through alternating functional transformation technique of the main support leg and auxiliary support leg, the bridge erecting machine can over the span to the next pier without the need of the guide beam. The operational process is simplified and the bridge erecting machine can erect box girder at the tunnel entrance and erect box girder inside the tunnel.

The engineers who designed that machine were very sure of their math and the crews that work with that machine are very trusting.
EDIT: That whooshing sound? It's the joke going over most of y'all's heads. 🙄
Or they need the job and have to take the risk
But no one using body harness
It's actually not quite as precarious as you might think. If you ever watched a stationary construction crane erected, it's pretty much the same principle. You definitely have to manage the load distribution, but if you do that and make sure that the pillar construction is precise its much safer than the alternative. (Scaffolding...which would also be ruinously expensive.)

Super cool to see this done!!! another one of life's mysteries solved
Haha yeah right!
Kinda... But then you think people made bridges like this/similar over 100 years ago, how did they do it!
What about all those build in the 1800 apparently? 🧐😳😁
@@truthfulfreedomfighter9123 ah fuck, U give me more mystery... Now i can't sleep any more...
Yes u r right 🔥
In the UK we would get around this problem by simply promising the project at election time and not carrying it out.
In the US we would get around it by promising the project after an election and a vote to increase the infrastructure by 50 million and take 20 years to finally get it done
As every another country in america lol
In Denmark, we will promise and talk about allocating the money. Then after 3-4 successive parliaments, eventually the project will get the green light to go into the next stage. This takes 10-15 years, to hear from the 5 farmers in the valley if they have objections or if any other people, for example environmentalist have anything against the bridge. One has! So another round of hearings if the bridge should be converted to a tunnel. Feasibility study says: not possible to build a tunnel trough a valley, they are more suited for mountains or underwater. Finally, a solution is found, but 15 years later, the original budget is insufficient. Back to parliament waiting for another election, so they can raise the budget. Construction of the bridge can finally start - and it doesn't take that long to complete. The only issue, humans stopped using cars and switched to autonomous flying drones.
In America, we just say the woke media is making are bridges too gay.
@@todortodorov940 Imagine taking infrastructure advice from environmental activists. You're basically saying "Yeah, we don't actually want to build this, we just want to make it look like we're doing something".
These (the construction workers) are the men who truly carry the world on their shoulders
This would have been described years ago as "an engineering marvel". Never find a better example than this. Kudos.

This was used to lay the railway that passes under Dartford Bridge and over the Dartford Tunnel road on the Essex side whilst the traffic carried on beneath. I worked on Tunnel Security during its construction to see contractors on snd off the Tunngel site.

Precasting segmental bridging was invented in 1930.
CHINESE MACHINE....SEEN THIS IN CHINA...THATS HOW THEY BUILD SO FAST SO MANY RAILS..AND BRIDGES...
I worked on the Jamestown bridge project in Rhode Island. We pre-cast 150 ft.segments weighing 2400 tons on a pier across the bay where they were floated on barges to the site and lifted into place by a hydraulic jack system. We were told that the operation was the heaviest lift over water ever done at that time, early 90s.

As an engineer, watching this makes me facepalm myself.. What a way to take unnecessary risks just to speed up the build process..
I guess life in China is really cheap.
@@footytube9500 engineer here, doesn't seem that risky, a well designed machine for placing the pre-stressed concrete spans that does the same job as cranes but efficiently.
Think of this like the automated ballast cleaner machines being used on the railways now, they can do the job faster than a team of workers doing it by hand, more consistently, and faster.
Unless you're talking about the lack of safety harnesses for the workers. In which cause I agree.
I never knew this, thanks for posting.

Imagine being the first to operate one of these. I'd be scared shitless.
That was my thought !
Being the first to operate any new machine is extremely terrifying, especially if it's the very first working prototype of the thing. So many things can just go wrong so fast but hey somebody still have to find these problems the hard way
Don’t swear please

Human ingenuity is amazing. Now imagine if human beings worked together instead of constantly being in a state of conflict. We would be in a more advanced state.
Absolutely not, it's when we are in conflict that we are working at our highest level! Take this video for example, we were fighting against nature and had to come out on top! No conflict- no motivation, no motivation- no innovation!
Some really intellectual comments out here
@@ambrishdubey2241 erection machine lol
@@jamesy6867 still intellectual comments ... 😂😂😂
That would require a single world government, and the conflict is in what gets to form the basis of it: complex and nuanced but popular democracy, versus simple and efficient but unchallengeable autocracy. The answer is likely somewhere in between, but then biased in which direction?
Its just incredible, the technology we have in this world today is unreal..
I wonder when we'll get it here in America.
It’s amazing the capacity our brains have to even create such technology, and America has the tech it’s just the humans here are brain dead to understand it the proper way.

I definitely love those bridge girder machines for a certain reason....
Wow...that was so wild I got chills...I love technology, humans can be very impressive from time to time, when they're being constructive.
The way each part moves without interference is amazing. Also the counter balance on one end must be a lot for the other end to not tip over.
On the subject of the counterbalance, preventing tipping isn’t really even hard considering how this works. Before you move the absolutely massive girder, said payload gives you plenty of counterbalance, and after the contact on the far pillar, the back wheels have so much leverage, again it’s probably several times more force than needed to prevent tipping. Not to say the design isn’t impressive, and impressively safe for these reasons.
I think the really impressive part on that subject though is the material science needed to make sure the rig is strong enough to not fail under those forces. I get that it’s “just” (as if this is easy) a matter of making the machine thicker to strengthen it, but even so, imagine how much force is put on the machine trying to fold it at any given point. Imagine the forces on the bridge itself trying to support this machine doing this. Those are also amazing points to think about.
@@jackmeovf4010 not at all related, but okay
It doesn't tip over because the counter balance on the one end works by asking some of the workers to stand at it in order to help weigh it down, lol! Seriously though this is a very interesting video to see this machine at work.
Pretty sure the concrete bridge section is way more dense than the body of the machine and so provides plenty of counterbalance.
It's all about leveraging.
So satisfying when it(concrete bridge pieces) that whole process becomes easier, by an advancement!
? That was awesome to watch!! The 🎶 jam kept me here!
Well i maybe useless to this world but humans are amazing.
U too are amazing!!!!!!!
nah, youre not useless. youre amazing, all by yourself. you just havent figured it out yet. you will, though.

Это считай время на её приезд, время на установку, время на уезд за следующей частью. Кран же поставил, перед ним эти мостовые плиты разгрузил и он катается вдоль моста и расставляет их, тоже не быстро, безопасность превыше всего всё таки, но перемещается он быстрее, да и далеко гонять за перемещаемым грузом не нужно.

This type of construction was used in the building of Wuppertal Schwebebahn monorail from 1899 to 1903 over a 13.3 km line over street and river locations. It still runs today. It was originally designed by Eugen Langen a super refinery engineer. Worth a visit to see something totally different in transport operation.
