Allied Locke Industries was founded in 1965 by Robert L. Crowson, as Allied Chains. In 1978, Allied Chains purchased Locke Steel Chain Co., a manufacturer of Agricultural chains since 1897. With this acquisition, Allied Chains broadened its offering and became one of the major producers of agricultural chains in the United States. At that time, the name of the company was changed to Allied-Locke Industries.

Allied-Locke Industries now includes five divisions: Agricultural Chain, Precision Roller Chain, Industrial Chain, Sprockets, and Environmental Products.

The company is comprised of a group of experienced and dedicated employees, committed to customer satisfaction through excellence in quality and service.
