Apparatus for aligning two sections of pipe, including a cage means made up of two half sections hinged together on one side and having closure means to close the opposite sides, a first end of the cage is adapted to bear against and grip one of the two sections of pipe, preferably through arcuate shoes, when the cage is closed and at least three independently operable pistons are spaced about the other end of the cage and are adapted to bear against and laterally move the other of the two sections of pipe, preferably through arcuate shoes on the ends of the piston rods, when the cage is closed and the pistons are activated. The ends of the cage are preferably spaced from one another to provide access to the area where the sections of pipe are being aligned and preferably a second set of pistons is longitudinally spaced from and aligned with the first set and a common shoe is mounted on each pair of longitudinally spaced piston rods.
