A carrier head which rides a rail is provided such that when connected by a load carrying member to a second carrier head on a second rail lateral movement is facilitated between the carriers to adjust for differences in distance between the rails. The carrier head has a surface for bearing the load while a pin positioned above the load supporting surface passes through a load bearing connector which permits movement of the load longitudinally.
