ABSTRACT:
A system for making and breaking connections between the pin ends of sucker rods and coupling sleeves employs a hydraulically powered system of radially driven gripper heads which are interchangeable to accept different sucker rod sizes. A torqueing system adjacent the gripper head system is also hydraulically driven, employing a pivotally coupled free end on a torque wrench which engages the wrench flat on the sucker rod at its opposite end. The coupling is securely retained without marring the coupling surface while the torque necessary to make or break the connection is applied rapidly and controllably. The system can also be used to advantage in preassemble sucker rods into couplings with precise prestress, using an improved connection design. A sucker rod string can then be assembled readily in the field with invariant optimum prestress conditions at each connection.
