Close enough for government work as they used to say. They both move and
grind what is beneath them.
Given enough weight from the tower the surface concrete will turn into a
fine powder by the motion of the steel base plate. This will act as a
lubricant.
Remove a plate that has been in place for many years and see for yourself.
