    Abstract: Embodiments of the invention relate to a gripping apparatus for supporting a tubular. The gripping apparatus may include a housing, a slip assembly disposed in the housing, and a leveling ring operable to move the slip assembly in the housing. The gripping apparatus may further include a guide member and a mating member operable to couple the slip assembly to the leveling ring. The longitudinal movement of the leveling ring directs the mating member along the guide member to radially displace the slip assembly relative to the housing.

    Abstract: The present invention generally relates to methods and apparatus for improving top drive operations. A method of ensuring safe operation of a top drive includes operating a top drive, thereby exerting torque on a first tubular to makeup or breakout a first threaded connection between the first tubular and a second tubular. The method further includes monitoring for break-out of a second connection between a quill of the top drive and the first tubular; and stopping operation of the top drive and/or notifying an operator of the top drive if break-out of the second connection is detected.
