Question:

How do they use cranes at +600 meters hight to build a building like the Burj Khalifa?

I just wonder they use cranes at such heights, how do they carry the cranes at such height? Helicopter or something? This is a picture of what I'm talking

Answer:

The cranes are jack-up cranes. They have their own self-contained jacks. As one floor is completed, they jack up to the next level. The cranes are on top of the buildings. They are designed by structural and mechanical engineers to loift a given weight.
