A method and apparatus for aligning the longitudinal margin of a loose sheet piling section above the mating margin of a set piling section to permit the piling sections to interlock. A base which supports a movable jaw mechanism is positioned on top of the set piling section. The jaw mechanism receives the loose piling section and includes rollers which guide the loose section as it is raised. When the loose section clears the top of the set section, a camming roller forces it laterally to align its margin above the mating margin of the set piling section. A further embodiment includes gripping elements on the base and interchangeable templates on the jaw mechanism which accommodate piling sections of various configurations. The templates carry universally rotatable rollers which guide the loose section and shift it laterally by camming action when it clears the top of the set piling section. A third embodiment provides a pair of jaws, one on each half of the device, so that piling sections can be interlocked with either edge of the set section. Each jaw opens and closes about a horizontal hinge axis to resist any tendency of the jaw to twist open if the loose piling section is out of plumb. Masts extend above the platform and alignment legs extend below the platform to assure accurate alignment of the piling sections.
