We operate a remote booster station several miles away via line of site microwave ethernet dish. The comms tower out at the booster tends to get hit every now and then. We recently replaced the ethernet line going out to the tower with fiber. Apparently, the voltage was jumping or induced into the ethernet copper cable just enough to fry our network switches at the tower and in our control room. It would either shut us down or cause faults. It fried our security camera on the tower twice this year. No issues since switching to the fiber. (we don't have a crossed fingers emoticon. tin foil hat seems inappropriate)
On cranes, standard practice is cranes don't operate and we clear people off steel structions and platforms for lightning within 8 or 10 miles. I have never seen a crane get struck though.
