I mean, yesterday I was walking in the city when I saw a huge crane installed in a field without other buildings or construction near of it. That thing was higher than anything around.
I still can’t understand how they are build. Please help.

Well first we’d have to understand what type of crane it was.
If it was a tower crane, then usually they dig a hole, fill it up with concrete and place big bolts into the concrete that the crane is attached to. They then use a smaller, mobile crane (one that can be moved around easily) to assemble the pieces of the tower crane that are brought in on trucks.
If it was what we call a crawler crane (a crane that sits on tracks or “crawlers”) then all those piece would be brought in on trucks and again assembled using a smaller, mobile crane.
The mobile cranes they use to assemble the bigger cranes are usually what we refer to as truck cranes. These cranes are mounted onto a truck and have a collapsible, or “telescopic” boom. They can be driven from place to place and set up on what are called outriggers to keep them from tipping over. There are also rough terrain or RT cranes that are similar to the truck cranes but don’t usually drive on the road. So, again, they are brought to the jobsites on trucks.
