Here is a view of the backshop of the Big Four at Mt.Carmel IL. Interesting that the crane operator is posing on the main beam. Larry Baggerly and a picture from Gene Millspaugh whose father worked as a Stationary Engineer here.
That's a great photo. The design of the locomotives and the men's clothing appear to date it as 1880-1890. But the crane appears to be electrically powered, so it may be after 1900. I don't know when electric motors were developed that could handle 100 Ton cranes.
