Since introducing the "freight industry's" first Edge-of-Dock leveler in 1962, DLM has continued to provide innovative ways to improve productivity and safety at the loading dock. Since that time DLM has expanded its manufacturing capabilities and become a world wide distributor of loading dock equipment. In 1994 DLM was acquired by Systems, Inc. and continues to provide superior structural construction and a national network of knowledgeable sales and service representatives.
