Bucyrus International, Inc. is a manufacturer of heavy mining equipment. Founded in Bucyrus, Ohio in 1880, the headquarters were moved to its current location in South Milwaukee, Wisconsin in 1893. It was an early producer of steam shovels. Its products now include large electric rope shovels, walking draglines, and rotary blasthole drills for the surface mining industry. Formerly Bucyrus-Erie, they built hundreds of large mining machines, as well as construction equipment, in an intense competition against competitor Marion Power Shovel. Bucyrus acquired Marion Power Shovel in 1997.
