The mobile crane then adds the counterweights. To rise to its maximum height, the crane grows itself one mast section at a time!

What is a self erecting crane?

A Self Erecting Tower Crane (SETC) is a Tower Crane that can be easily inserted on a site with restricted space in a short period of time. These cranes operate from a fixed position and must be safely placed on site by qualified field engineers familiar with the mechanisms that they are using.

Are cranes built into buildings?
