<p>The present invention provides a chain having links each of which comprises opposed C-shaped end portions connected by joining limb portions. The links are constructed such that when viewed normal to the plane of a link, each link presents a waisted configuration at the joining limb portions. Alternatively, the outer peripheral parts of the joining limb portions can have bevelled edges so that the link presents a waisted or scalloped form when viewed at 40.degree. to 90.degree. to the plane of the link. A central stud is preferably provided in each link. By arranging the chain links to have the above configuration, the stress loading of the chain can be considerably improved, particularly for the case where the chain is passing around a wildcat, fairlead, hawsepipe or other curving chain guide means.</p> |
