    The engineers who designed that machine were very sure of their math and the crews that work with that machine are very trusting.

      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 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.

  • @dragonite986

    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.

    • @Genny207
      @Genny207 2 года назад +82

      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.

    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.

    I worked right near this very machine when the Channel Tunnel Rail link was being made through Kent to London. It was used to build a bridge over the M25 at Dartford without closing it to traffic. I believe it may have been the first use of the machine, but not certain.
