Not so long ago I was wondering how they build a crane when it would seem they would need one to build one. A suggestion was made which seemed plausible and was bound in fact (witnessing said crane being build counts as primary evidence I reckon). But on Saturday I think I saw another option. In order to build a crane you have a telescopic mobile crane like this:
It's attached to the back of a lorry and has feet which extend out the sides and stand on the ground like stabilizers. So that's that question tied up.
