Surely you’ve seen a crane at least once in your life, especially if you’re near an urban area with lots of construction. If you don’t know what a crane is, it’s a tall machine used to lift heavy objects to high places using a system of pulleys. They’re amazing machines if you think about it.
The thing is, there’s no crane when you leave for work, and when you come back, there is, leaving us all puzzled. How did the construction workers get the crane up so fast?
I have a proposition:
No, but seriously, the real method is just as good. I thought my friend was joking when he said it, and I’m pretty sure he was, but he was correct. Cranes build themselves!
The crew uses a smaller mobile crane to assemble the initial components of the crane, then the crane builds itself up to the desired height.
There’s yet another mind-boggling question that’s unanswered: with no support wires, why don’t these cranes topple over? You have this really tall structure with a relatively small base, and if it didn’t have a good way of securing itself, it would certainly topple with the slightest wind.
Can you take a guess? It’s a really simple solution.
Weeks before the crane arrives, the construction workers pour and set a large concrete base on which to set the crane. When the crane arrives, they bolt it into the base with really large bolts.
Cranes are simply fascinating. They help us lift large and heavy objects to high places, all without toppling over. Everything from their construction to their operation is just mind-boggling. You’re free to think that this is all the work of aliens, of course, but I think that the tower crane is one of the best specimens for showcasing some of the amazing things we humans are capable of.
