Tower cranes

I know that we have at least one member knowledgeable about cranes, so my question is about tower cranes.
When a tower crane is installed on a construction site, do they sink a foundation? If so, how is it fastened to the structure?
Are modern tower cranes operated remotely from the ground? Are they electric?
Attached is a photo of one with little obvious visible support (IMO).

One of the largest crawler cranes in Asia, a 1,600t lift capacity Terex Demag CC 8800-1, is being used to erect a gigantic polythene reactor at Dagang, China.

A Derbyshire home is back on the market seven months after a 26-tonne mobile crane smashed into it.

What is reputed to be Europe's largest mobile crane has come to Scotland.
The components of the 1,200 tonne crane were transported to Scotland in 45 lorries.

It will take an hour-and-a-half to move and secure each beam. The 190ft machine will be used to lift eight large beams
At least that brings the hourly rate down . . .
