Abstract:
A lifting apparatus for lifting drill string components from a wellbore, the lifting apparatus comprising: upper and lower support elements, each of the support elements having a central aperture passing therethrough; a lifting arrangement which is operable to vary the distance between the upper and lower support elements between a first, relatively short distance and a second, relatively long distance; and selective gripping arrangements held or supported by the upper and lower support elements, respectively, each selective gripping arrangement being operable to apply a gripping force to the exterior of a substantially tubular element passing through the central apertures of the upper and lower support elements, wherein the selective gripping arrangements may be activated or deactivated independently of one another.

Claim (Index 1):
A lifting apparatus for lifting drill string components from a wellbore, the lifting apparatus comprising:\n upper and lower support elements, each of the support elements having a central aperture passing therethrough; a lifting arrangement which is operable to vary the distance between the upper and lower support elements between a first, relatively short distance and a second, relatively long distance; and selective gripping arrangements held or supported by the upper and lower support elements, respectively, each selective gripping arrangement being operable to apply a gripping force to the exterior of a substantially tubular element passing through the central apertures of the upper and lower support elements, wherein the selective gripping arrangements may be activated or deactivated independently of one another, wherein the upper and lower support elements each have an inner surface defining the central aperture, and an outer surface, and a slot passing through the entire depth of the element and providing communication between the inner surface and the outer surface, and wherein the central apertures of the upper and lower support elements are at least partially aligned with another, and the slots of the upper and lower support elements are at least partially aligned with one another.
