摘要:
An apparatus and a method for positioning a tubular relative to a tong is provided. In one aspect, a positioning tool may be mounted on a lower portion of the tong. The positioning tool includes a positioning member for determining a position of the tubular and a centering member for engaging the tubular. The positioning tool further includes an actuation device for actuating the centering member. The position of the tubular may be actively adjusted by actuating the centering member.
