how are cranes built?

Answer 1

i know this sounds daft but when i worked in the building trade usually by the crane itself and a smaller crane onsite.

Answer 2

No. They are lifted into place in sections by one or more other cranes, the telescopic arm kind, which are either in a nearby street or on the building site. I watched several being built and then dismantled over a period of three years at a large development across the street from my house. However, I saw a TV programme about how they built one on top of a mountain, and there they used helicopters to lower the sections into place.

Are you talking about the bird or the piece of construction equipment.

If your talking aboout the piece of construction equipment, there are about 20 major types of cranes. Each having a different purpose. Some are fix and move on a linear track, some are placed on top of buildings to move construction material.

Basically they are made of steel, that utilize pulleys and steel cable, which is reeled in and out by a motor.
