Tower crane 4808 is used to lift building material such as concrete, steel bars vertically and horizonally.
All tower cranes consist of the same basic parts:
1. The base is bolted to a large concrete pad that supports the crane.
2. The base connects to the mast (or tower), which gives the tower crane its height.
3. Attached to the top of the mast is the slewing unit (large ring-gear and motor) that allows the
crane to rotate.
4. Attached to the slewing unit is the jib (or boom), the machinery arm, the counterweights
and, the Operators cabin
