Abstract
Apparatus and methods for engaging and gripping a tubular, with the apparatus including a sleeve having a body defining an internal chamber therein, with the sleeve configured to receive the tubular through the internal chamber. The apparatus may also include a laterally translatable spider disposed at least partially in the sleeve and including a bore to receive the tubular.
Claims20
A floating spider assembly for engaging a tubular, comprising:
- a sleeve having a body defining an internal chamber therein, the sleeve configured to receive the tubular through the internal chamber;
- and
- a laterally translatable spider disposed at least partially in the sleeve and including a bore to receive the tubular,
- wherein the spider is coupled to the sleeve such that the spider is laterally translatable relative to the sleeve.

An apparatus for supporting a tubular, comprising:
- a tubular gripping device defining a bore for receiving the tubular and one or more gripping members configured to selectively engage and support the tubular;
- and
- a sleeve including a top, a bottom, and a body extending therebetween, the top and bottom each defining a bore, the bore of the top and the bore of the bottom being substantially concentric, the body defining an internal chamber sized to receive the tubular gripping device at least partially therein and to provide a radial clearance between the tubular gripping device and the body, the tubular gripping device being free to translate in a lateral direction relative the sleeve such that the bore of the tubular gripping device is configured to be moved off-center with respect to the bore of the top and the bore of the bottom.
A method for gripping a tubular, comprising:
- receiving a spider in a sleeve;
- receiving the tubular through a bore in the spider and through the sleeve;
- gripping the tubular with the spider;
- and
- laterally translating the spider with respect to the sleeve.
