A clamping device for supporting a well string in a borehole includes a base plate with a central opening and primary clamp body clamp body supported for linear motion relative to the base plate. The clamping device further includes other clamp bodies supported for independent linear motion relative to the base plate. In certain embodiments, the clamping bodies are supported for pivoting motion to open and close the central opening. Each of the clamp bodies carries a gripping member on a face thereof for engaging a well string component received in the central opening. A drive mechanism is coupled to the clamp bodies and configured to move the clamp bodies relative to the base plate.

Apparatus for suspending a downhole well string

An apparatus for handling a pipe having a body, the body defining an open throat that is adapted to receive a pipe, a plurality of jaws hingedly mounted to the body that are adapted to engage a pipe while preventing the pipe from engaging the body, each of the jaws defining a concave portion that is adapted to engage the pipe, the apparatus further including respective over-center mechanisms that are arranged between and operatively coupled to the body and each one of the plurality of jaws, each respective over-center mechanism being adapted to inhibit a respective one of the plurality of jaws from closing when jaws are open and to inhibit a respective one of the plurality of jaws from opening and disengaging from a pipe when the jaws are closed on the pipe.

Apparatus and method for facilitating handling pipe

Generally, the present disclosure is directed to wellbore tubular running systems and methods of their use. In one illustrative embodiment, a tubular running system is disclosed that includes, among other things, a torque frame, a main shaft extending through a top opening of the torque frame and rotatable by rotation apparatus, slip setting apparatus connected to the torque frame and including a levelling beam and a plurality of slip assemblies, each of the slip assemblies connected independently and pivotably to the levelling beam, and movement apparatus connected to the levelling beam for moving the slip assemblies in unison with respect to a tubular projecting into the torque frame.
