Zusammenfassung: | A spider for handling/gripping well components of various sizes can include multiple slip assemblies distributed circumferentially about a central axis, each slip assembly including a slip carrier radially displaceable relative to the central axis, a slip displaceable relative to the slip carrier, and a slip actuator operable to displace the slip relative to the slip carrier, the slip actuator being disposed at least partially internal to the slip carrier. Each slip assembly may include a slip carrier actuator that radially displaces the slip carrier. A table assembly may mount to a well rig with an upper surface of the table assembly being flush with a rig floor of the well rig. Another spider can include a pipe guide assembly with multiple guides and guide actuators. Each guide actuator rotates a respective one of the pipe guides about a respective guide axis that is parallel to the central axis. |
