Aside from the obvious gravity defiance those magnets can only lift about 5 tons while those machines weigh 30-40 ldo.
There are no magnets tbh.
So what is the function of that gigantic square thing then? I don't see how it could be anything else.
I believe it's all mechanical.
So you don't know what its function is? The point of the mindfuck is that the magnet is supposedly strong enough to lift the machine up the tower. Those machines are actually made to allow junkyard workers to move several tons of cars, car parts, etc. at once among other things.
Kil, you're wrong. You can see in the first pic that the 'gigantic square thing' slots perfectly into four sections of the tower plus the top angled section. In the third pic you can see that the tracks of the excavator lock into the other custom built sections of the tower, allowing it to lean and sit as the scoop/square thing slots into the next highest section. No magnets would be required, it would rely solely on gravity, the skill of the driver and the strength of the hydraulic arm to be able to climb the tower as shown. It wouldn't surprise me at all if it was real.
