Tower Cranes

0


Tower cranes are a common fixture at any major construction site. They're pretty hard to miss. They often rise hundreds of feet into the air, and can reach out just as far. The construction crew uses the tower crane to lift steel, concrete, large tools like acetylene torches and generators, and a wide variety of other building materials.

Tower cranes rise 150 feet in the air and lift up to 19 tons. Plus, they actually build themselves! They're simply amazing. Learn how these structures accomplish such feats.
