Abstract:
A pipe handling apparatus has a base, a main rotating structural member pivotally connected to the base, a pipe handler connected to the main rotating structural member for moving a pipe from a generally horizontal orientation to a vertical orientation, and a jack connected to the pipe handler. The jack exerts a downward force in generally parallel relation to the pipe when the pipe is in the vertical orientation. The pipe handler has a gripping structure for gripping an outer surface of the pipe. The gripping structure has a stab frame. The jack is affixed to the stab frame. The jack has a piston-and-cylinder assembly positioned relative to the stab frame, and a hydraulic actuator connected to the piston-and-cylinder assembly. The hydraulic actuator 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.
