The history of Kelley Atlantic is uncertain. It is surmised that former employees of Kelley left and started their own company and their own line of dock equipment. This would explain why many of the Kelley parts fit the Kelley Atlantic dock levelers. It's not unusual for new start ups to build on the name of other, more established companies. After a time the company was unable to sustain itself financially and the assets appear to have been assumed by Kelley Manufacturing. Kelly Atlantic dock leveler parts are still available through Kelley and after market suppliers who manufacture OEM equivalent replacement parts.
