A PIPE HANDLING APPARATUS (10) HAS A BASE (214), A MAIN ROTATING STRUCTURAL MEMBER (16) PIVOTALLY CONNECTED TO THE BASE (214), A PIPE HANDLER (218) CONNECTED TO THE MAIN ROTATING STRUCTURAL MEMBER (214) FOR MOVING A PIPE (18) FROM A GENERALLY HORIZONTAL ORIENTATION TO A VERTICAL ORIENTATION, AND A JACK (200) CONNECTED TO THE PIPE HANDLER (218). THE JACK (200) EXERTS A DOWNWARD FORCE IN GENERALLY PARALLEL RELATION TO THE PIPE WHEN THE PIPE IS IN THE VERTICAL ORIENTATION. THE PIPE HANDLER (218) HAS A GRIPPING STRUCTURE (26) FOR GRIPPING AN OUTER SURFACE OF THE PIPE. THE GRIPPING STRUCTURE (26) HAS A STAB FRAME (28). THE JACK (200) IS AFFIXED TO THE STAB FRAME (28). THE JACK (200) HAS A PISTON-AND-CYLINDER ASSEMBLY POSITIONED RELATIVE TO THE STAB FRAME, AND A HYDRAULIC ACTUATOR (212) CONNECTED TO THE PISTON-AND-CYLINDER ASSEMBLY. THE HYDRAULIC ACTUATOR (212) IS SUITABLE FOR PASSING HYDRAULIC FLUID TO THE PISTON-AND-CYLINDER ASSEMBLY SO AS TO MOVE THE PISTON-AND-CYLINDER ASSEMBLY FROM A RETRACTED POSITION TO AN EXTENDED POSITION. |
