This is really cool.  How cranes are assembled is one of those things that would never have occurred to me to think about. As it turns out, it’s a pretty complex and creative affair.  Engineers must have spent some serious time thinking through the implications of trying to ratchet such a monstrous and durable item way up in the air.

Watch animations of two different types of cranes going up.
