Abstract
The track is equipped with a plurality of bands, which extend parallel to one another in the direction of motion and which are interconnected by a large number of steel crosspieces in the transverse direction. The crosspieces have a U-shaped cross-section and are equipped with a U-shaped yoke composed of two U-legs and of a connection web extending therebetween. The first U-leg has a connecting leg as an extension, said connecting leg extending inwards via a bend and being followed, after an additional bend, by a sword, which extends approximately parallel to said U-legs. Offering the advantage of economy-priced production, said steel crosspiece is intended to show more advantageous resistance values. This is achieved on the basis of the features that the second U-leg is welded to the end of the first connecting leg via an inwardly bent, second connecting leg and that a house-like hollow space is thus formed in the interior of the U-shaped yoke.
