- 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.)

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
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? 🧐😳😁

I worked on the Jamestown bridge project in Rhode Island.

We were told that the operation was the heaviest lift over water ever done at that time, early 90s.

@@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.

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!

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?

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.
What i found most amazing were all the workers clambering up and down without any safety gear. No way would I do that!
It's likely china without safety regulations heh
Chinese, one drops down dead and is immediately replaced.
They don’t have OSHA

so they have to first design the bridge for weight of this machine as well, this definitely increases the wastage of materials used in bridge.

Sure but look at all of the wheels it has. The pressure per square foot is probably manageable and may not require much additional engineering as long as the machine moves slowly and smoothly.
