    摘要： 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.
