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.

In this article, you'll find out the answers to all of these questions and more!
