ABSTRACT:
Pipe, bar stock, or other tubular member handling apparatus according to this invention includes means for elevating a section of pipe from a horizontal pipe rack, moving the pipe linearly into operative relation with a machine that rotates the pipe and does work such as machining threads at the end of the pipe, supporting the pipe for rotation during machining operations, moving the pipe linearly in the opposite direction after machining operations have been completed and then lowering the pipe back onto the pipe rack. The machine incorporates operation and control circuitry correlating certain pipe control movements and facilitating pipe handling with minimum control selection by operating personnel and minimizing handling time. An adjustable, limit switch-controlled electrohydraulic control circuit enables utilization of the machine for pipes of different size and further enables simple and efficient positioning of the center line of the pipe in colinear relation with the center line of the pipe handling machine.
