ABSTRACT:
A power tong has two powered rings mounted on the tong frame for independent rotation, one ring, a reel carrier, carries a plurality of spring rewind line storage reels. Independent lines extend from each reel and each line is anchored to the second powered ring. An open gap, or throat, extends to the tong center to receive pipe when the lines are all recovered into the reels. The reel carrier ring is rotated to wrap the lines in a spiral pattern around pipe. The second ring is driven to pull the lines and the reel carrier ring is braked to apply tailing tension to the lines but does then turn in sympathy with the second ring to turn pipe. To recover the lines, the second ring is stopped and the reel carrier ring is driven in the direction to allow lines to return to the reels as they unwrap from the pipe.
