摘要

The gang planks (45) have longitudinal beams (53), hanging means and transverse reinforcement sections (50) with opposing wall parts of which at least one prior to connection is formed free of holes. The connecting means for connecting the beams to the reinforcements are designed to be made fully automatically directly with electrically or pressure-induced hot or cold material flows of connecting structures formed by at least one of the wall parts . The long beams are fixedly connected under the tread surface plate to the lower arm (84) of the cross reinforcement with a connecting tab (75) connected to at least one of the connectors having the connecting structures (191.1)
