LeTourneau Technologies, Inc. was an American manufacturer of heavy construction equipment founded by R. G. LeTourneau. In 2011, the company was acquired by Joy Global.


R. G. LeTourneau, also the founder of LeTourneau University, founded 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 rig. In 1955, it made the first log-stacker machine. In 1965, the company made the first straddle carrier.

In 1970, just after the death of the founder, the company was sold to Marathon Manufacturing Company and was renamed Marathon LeTourneau Company.

In 1994, Rowan (now Valaris plc), which had used the company to manufacture its drilling rigs, acquired the company from General Cable for $50 million.[2][3]

In 2011, Rowan (now Valaris plc) sold LeTourneau Technologies to Joy Global.[4] Joy Global subsequently sold LeTourneau's Drilling, Marine, and Power divisions to Cameron International.[5]

In 2016, Keppel Corporation acquired LeTourneau Offshore Products (jackups, cranes, and elevating units) from Cameron, while Cameron retained the LeTourneau Drilling Products division.[6]
