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 24):
A method comprising:\n providing a lifting apparatus according to  claim 1 ; passing a substantially tubular element through the central apertures of the upper and lower support elements, so that the substantially tubular element extends continuously through the central apertures of the upper and lower support elements; and removing the substantially tubular element from the lifting apparatus in a generally lateral direction by passing the substantially tubular element through the slots of the upper and lower support elements so that the substantially tubular element is entirely removed from the lifting apparatus.
