How drilling tongs work
It is important to note that you need to have sets of tongs used in opposition to one another. This means one set of the tongs will be tied with a cable, or a chain, to the derrick. The second set of tongs will be pulled using mechanical catheads. The tongs that are helping to loosen the drill string are called the breakout tongs, while tongs that are tightening the drill string are called makeup tongs.
