ABSTRACT:
Apparatus and method for positioning a wing panel or other member for riveting or conducting other operations thereon. The member is loaded at floor level on a plurality of hydraulic cylinders spaced over the length thereof and raised to a position for conducting the operations thereon. The hydraulic fluid flow to and from the hydraulic cylinders is controlled to synchronize the movements of the cylinder piston rods so that each of the piston rods bears its share of the load throughout raising and lowering of the member. The cylinders are also individually operated to accommodate passage of riveting machine heads or other tooling relative to the member.
