Unified Industries, Inc. was founded by John Miller as a small fixture and gaging shop in Eaton Rapids, Michigan. In 1953, Unified became incorporated and moved operations to Howell, Michigan, where it has produced patented rail trolleys and bridge cranes widely regarded as the industry benchmark ever since.

Increasing demand for its innovative material handling equipment led to the introduction of the "ETA" line of aluminum enclosed track bridge cranes and monorail systems in 1985. Unified became the first in the industry to offer customers an aluminum track system while utilizing trolleys with high-impact nylon rollers for unparalleled ease of movement.

Since then, Unified has established a reputation as a worldwide industry leader in providing material handling equipment that systems installers depend on. Unified joined the Columbus McKinnon family in 2017 and in 2019 moved to a high-technology, state-of-the-art facility in Brighton, Michigan.
