Bucyrus-Erie was an American surface and underground mining equipment company. Founded as Bucyrus Foundry and Manufacturing Company in Bucyrus, Ohio, in 1880, Bucyrus moved company headquarters to South Milwaukee, Wisconsin in 1893. In 1927, Bucyrus merged with the Erie Steam Shovel Company to form Bucyrus-Erie.
Renamed Bucyrus International, Inc. in 1997, it was purchased by Caterpillar Inc. in a US$8.8 billion transaction that closed on July 8, 2011. At the time of its acquisition, the Bucyrus product line included a range of material removal and material handling products used in both surface and underground mining.
The company changed its name to Bucyrus-Erie in 1927 when it merged with the Erie Steam Shovel Company, the country's leading manufacturer of small excavators at that time.
In 1930 Bucyrus joined with the English firm of Ruston & Hornsby Ltd Lincoln, England, to form the Ruston-Bucyrus Ltd firm in England. Ruston & Hornsby Ltd were the pre-eminent manufactures of Steam excavators at the time, having started in 1874; the merger gave the company access to previously unavailable world markets.
Ruston & Hornsby Ltd sold their share in Ruston-Bucyrus in 1985, during a period of recession and consolidation in the Mining industry, as they divested themselves of non-core businesses to survive.
For a time in the 1980s the company was known as Becor Western following its merger with Western Gear.
On February 22, 1993, Bucyrus-Erie filed for Chapter 11 bankruptcy, and remained under bankruptcy protection until December 14, 1994.
The company took its current name, Bucyrus International, Inc. in 1997.
On May 4, 2007, Bucyrus completed the acquisition of the DBT Group, a Lunen, Germany based manufacturer of underground mining equipment, from RAG Coal International AG of Herne, Germany. Bucyrus acquired DBT because DBT's underground mining equipment complemented Bucyrus' surface mining products.
In February 2010, Bucyrus International completed a US $1.3 billion acquisition of the mining equipment division of Terex Corporation.
On November 15, 2010, Bucyrus agreed to be acquired by Caterpillar in a transaction valued at US$8.6 billion. Caterpillar said it intended to create a new mining business headquarters at the former Bucyrus headquarters location in South Milwaukee. The transaction closed in mid-2011.
