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.
