ESCO Corporation is a manufacturer of engineered metal wearparts and components for industrial applications – including mining and construction. Since 1913, the privately held company has been headquartered in Portland, Oregon, USA, and has manufacturing sites throughout the world. The company designs and manufactures a host of products including ground engaging tools (GET) for mining, construction products, conveying, rigging, dredging and other industrial applications. The company also owns two companies that design and manufacture specialty drilling tools for the oil and gas industry. ESCO was founded in 1913 by Oregon businessman Charles (C.F.) Swigert as a local source of steel castings. The Electric Steel Foundry Company was founded on property once occupied by the 1905 Lewis and Clark Centennial Exposition. The foundry used an unusual modern furnace that was fired by electricity rather than coke, making it the first of its kind in the western United States. During its first 30 years, ESCO was mainly a regional supplier of cast steel alloy products for the logging, construction, and pulp and paper industry throughout the Pacific Northwest. In the 1920s, the company expanded production to include cast steel alloy products like the Bardon choker hook, widely used in forestry. Further growth was sparked by the use of Hadfield manganese steel and the production of dragline excavator buckets. The ESCO trademark was first used in 1926 and eventually became the company’s new name.
