There's usually lots of steps and ladder climbing involved, most of it carrying big wrenches, hammers, and pry bars. Most cooling towers seem to be built with the assumption that no one will ever need to get to the fan, gearbox, or shaft again, so there may not be a place to stand inside of the cell. And it's a long way down to the basin.

Rolling (metalworking) - Wikipedia
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough.Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its ...
