ABSTRACT:
An apparatus for rotating a tubular member. The apparatus has a housing with a recess for receiving the tubular member; a latch for closing off the recess; an operating means for the latch; a gear rim; discs within the housing to guide and retain the gear rim; a power means for driving the gear rim; and a crescent-shaped carrier member within the gear rim having means for contacting and gripping the tubular member. Either forward or reverse rotation of the gear rim results in the gripping of the tubular member and the imparting of torsion to the tubular member.
