Is this a common way to install a tower, and does it make sense?

Some towers have a swivel to allow for twisting
but the base under the swivel is firmly embedded
in concrete.

Hi All:

I've seen profesonal towers put up that way, sorta. They had a single pin
that a hole in the flat tower base set over. The pressure of the guys keeps
the base on the concret pad and the pin keeps it from kicking out to the
side. With out the pin, it's going to come done sometime.
