Iron roughneck

An iron roughneck is a piece of hydraulic machinery used to "handle" (connect and disconnect) segments of pipe in a modern drilling rig.^[1] The segments can be manipulated as they are hoisted into and out of a borehole. This type of work was previously performed manually by workers using tongs,^[1] and was one of the most dangerous jobs in a drilling operation. However, with iron roughnecks and modern technology, much of this can be done remotely with minimal manual handling.^[2]

Automated roughnecks became common in deep-water drilling and were later adopted by onshore rigs.^[1]
