| 摘要 |
The invention relates to a track rail for a suspension conveyor system particularly for the convenience of materials in the textile industry, having a cross-sectional configuration comprising a pair of roof-shaped converging legs each formed with a roller track surface for one of a pair of track rollers on its upper side, and connected to a carrier rail by an upper carrier web extending in the symmetry plane, said track rollers of said track roller pair defining a derail gap and being mounted in a common yoke with their axes in oblique alignment relative to one another, permitting them to be detached from said track rail by lifting said yoke and tilting it transversely of said track rail. Known track rails are formed as a welded construction composed of continuous steel sections and web sections as the carrier web. They are heavy and permit only the use of center-suspension track roller pairs to travel thereon. Due moreover to the material accumulation at the intersection of the legs thay have unsatisfactory load-carrying properties, and their assembly is laborious and troublesome. According to the invention there is provided a universally employable track rail of lower weight and improved usefulness as compared to the known construction by providing between said legs a transverse web formed integrally therewith and extending transversely of said symmetry plane so as to define a closed cavity with said legs.
