Frank Bauman started Bauman Sign in 1965. The sign business needed a crane to install their work, so they purchased a pole crane. These cranes were very basic, but functional and inexpensive for light work. As time went on, demand grew for crane services, and Frank started focusing on the crane service and dropped the sign work.

Frank continually grew the fleet and the staff to handle work in the surrounding areas. Focusing on a high level of service, Bauman Crane swung a lot of building trusses and various mechanical installations. As tree removals began utilizing cranes, Bauman Crane began this service as well.
