Self-propelled cranes ("locomotive cranes") go all the way back to 1859, when the first one was built in England. First US-built locomotive crane was built by Weston Crane Company, a subsidiary of Yale & Towne, in about 1884, but they were rare until the late 1890s, when sales took off, propelled mainly by private industry. Many thousand have been built since.

Self-propelled wreckers began about 1892, first built by Industrial Works. As Frank points out, not all wreckers were self-propelled, but the majority were. They did not develop enough tractive effort to move more then a couple of cars, and in practice self-propulsion was usually used to position the wrecker for minor work. The propelling mechanism was not that robust, and there are cases on record of a wrecker "stripping its gears" and running away on a grade.

With locomotive cranes, which were much lighter, the propelling mechanism had to be robust, as being able to move about and switch cars into position, without the services of a locomotive, was fundamental to the crane's success.

Tim, I think you suspect the response you got was bovinus manurem, and
you would be right. A Southern Railway "List and Description of
Derricks" (not the best copy, may be dated 1945) shows that most of
them, including Bucyrus and Industrial Works derricks, were

any definite answers about self-propulsion.

A crane ain't a caboose, or a passenger car, or a loco -- so it
must be a freight car! :-)
