A plate-link chain formed from short plate links and long plate links. The long plate links have an extension at one end. The installation direction of the long plate links is such that their extensions overlap plate links in an adjacent row and that are next in order in the longitudinal direction of the plate-link chain, when viewed from the side of the chain. The overlap permits the plate links to have defined positions relative to adjacent plate links by minimizing the ability of adjacent plate links to shift laterally relative to each other.
