Help me out here please, if you can. I'm trying to figure out when the below type of crane was officially invented, and used. My findings do not match the official version. I am probably looking in the wrong places, so I need some assistance figuring this out

KD: In general it appears we have something weird going on with these tower cranes. The official date of the invention of this type of crane is listed as 1910-1913. May be the crane above is not considered to be a tower crane, I don't know. It sure does look like one.
The photograph pertains to 1894-1897.
