A universal joint-link chain comprising a plurality of chain links, one end of each chain link being provided with a hinge body and the opposite end with a hinge socket, the hinge socket of one chain link receiving the hinge body of the neighboring chain link. Each hinge socket and each hinge body is formed as an equatorial spherical segment, and a respective shaft mounts each hinge body. Travelling wheels are provided at opposed ends of the shaft. There is also provided a substantially C-shaped guide channel which is downwardly open, has spaced apart confronting flanges and a rear channel wall oppositely spaced from said flanges. A guide wheel is arranged at the region of the travelling wheels, said guide wheel having an axis extending essentially perpendicular to a related connection element and through the center of the associated spherical segment. The confronting flanges both guide thereon the travelling wheels and therebetween the guide wheels. Support means carried by each chain link include means for the attachment of a conveyed material, and said attachment means of the support means comprise a lateral offloading attachment element. The offloading attachment element extends substantially parallel to and in vertically spaced relationship from the axis of the shaft. The lateral offloading attachment element, when loaded by said conveyed material, exerting a moment upon the travelling wheels such that one travelling wheel at an end of the shaft bears against its related flange while the other travelling wheel at the other end of the shaft bears against the rear channel wall to provide a stable position for the universal joint-link chain. |
