Abstract: A torque head (100) for gripping tubular members has a housing, grip mechanism secured within the housing (102) for selectively gripping a tubular member, the grip mechanism including at least one jaw (141, 142, 143) selectively movable toward and away from a portion of a tubular member (12) within the housing, the at least one jaw having mounted thereon slip apparatus for engaging the portion of the tubular member, the slope apparatus including die apparatus movably mounted to the at least one jaw, the die apparatus movable with respect to the at least one jaw so that relative movement of the tubular with respect to the torque head is possible to the extent that the die apparatus is movable.

Abstract: A system (10) according to the present invention includes a top drive (20), a torque wrench assembly (30) used for back-up, an elevator (40) (which may also be any suitable known suspendable selective clamping apparatus or device), a pipe handler (50), and a torque head (100). The elevator (40) is suspended by bails (42) from eyes (22) of the top drive (20). The torque wrench assembly (30) is suspended by a support (32) from the top drive (20). A joint compensator (224) is positioned as desired, e.g. but not limited to between the torque head (100) and the top drive (20).
