Old Cranes, are they diesel related? Yes, in fact, most cranes have two power sources, one to move the crane and one to lift the load. Much like these two. I am unsure of the year for both makes. Lorain Crane appears to no longer be a commercial name plate while American Crane still exists in some form. If you know more about these two cranes let me know.
