Abstract
Abstract An elongate-material transport system including a cross transport for loading elongate material onto a roller way into which horizontal guide portions of the roller way extend; the cross transport has a power driven wagon system mounted on a horizontal guide system which is elevatable on a vertical guide system made jam-resistant by special contour of the moving portion, which is fixed to the horizontal guide portion; the roller conveyor has a longitudinal rail above one edge with a space beneath for receiving an end of the wagon system to align elongate material carried on the wagon system, and the wagon system has edges adapted for driving elongate members against the rail in aligning them.
