FIELD: construction.
SUBSTANCE: crane rail is manufactured from a steel tape produced by form rolling. The crane rail has an upper belt and a lower belt. On the upper belt there is an additional carrier belt, which is triangular in cross section. Edges of the steel tape are welded to a crosslink by means of laser welding. Special reinforcement is designed to fix the crane rail.
