    How do they erect those huge cranes that are taller than buildings that you see on construction sites?

    Self erecting tower cranes. The mast is raised using hydraulic rams and another section is lifted using the same crane and hoisted into position. Once securely bolted in place, the process begins again.

    Liebherr do some great mobile ones too...
