Broadwind Energy Inc., the fabricators and manufacturer, will produce welded sub-assemblies for Caterpillar’s large draglines, crawlers, and excavating equipment, according to a new contract. The value of the assignment was not announced.

Illinois-based Broadwind said the work will be carried out at its plants in Abilene, Tex., and Manitowoc, Wis. Broadwind is recognized as a fabricator of structures and components for energy and construction projects. Examples include windmills and structures for oil-and-gas drilling, and mining operations, as well as gears and gearing systems for those installations.

Together with a large volume of new work assembling wind towers, Broadwind estimated the Caterpillar contract would cause it to hire up to 50 new workers during 2012. Broadwind has about 800 workers currently.

“This collaboration fits well with our strategic initiatives to leverage our core competencies beyond the wind industry, and diversify our revenue base,” stated Broadwind Towers president Paul Smith. “We believe this is the first step in expanding our relationship with Caterpillar as we continue to collaborate.”
