The Superior-Lidgerwood-Mundy Corporation (SLM Corp.) is the result of the combining of three companies who were engaged in similar activities. The Lidgerwood Manufacturing Company (Est. 1873) was originally located in Brooklyn, New York. Subsequently, additional plant facilities were necessary and, as a result, Lidgerwood purchased the Superior Iron Works (Est. 1895) of Superior, Wisconsin and Mundy Hoisting (Est. 1879) of Newark, NJ. Now all manufacturing and administrative activities of Superior-Lidgerwood-Mundy are accomplished at Superior, Wisconsin, which has over 65,000 sq ft of manufacturing and warehouse space.
