LeTourneau Technologies, Inc. is an American manufacturer of heavy construction equipment founded by R. G. LeTourneau.
History
R. G. LeTourneau founded his company R.G. LeTourneau, Inc. in 1929 in California as a contractor of earthmoving equipment. LeTourneau manufactured products in Longview, Texas.[1] During World War II, the company provided 70% of the Allies' earthmoving equipment. In 1954, it built the first jack-up drilling platform. In 1955, it made the first log-stacker machine. In 1965, the company made the first intermodal crane.[2]
Marathon LeTourneau Company designed all of Rowan Companies' jack-up rigs, and delivered the last one to Rowan as an independent company in 1986.[3]
In 1994, Rowan Companies acquired the assets of Marathon LeTourneau Company.[3]
In 2004, LeTourneau formed an alliance with SourceOne Drilling Systems.[2]
In 2006, LeTourneau changed its name to LeTourneau Technologies, Inc.[2]
In 2011, Rowan announced the sale of LeTourneau Technologies to Joy Global.[4] The sale of LeTourneau Technologies to Joy Global was completed in late 2011. Joy Global subsequently sold LeTourneau's Drilling, Marine, and Power divisions to Cameron International in October 2011.[5]
