| 摘要 |
<p>The invention relates to a heavy duty chain -containing chain- links comprising synthetic polymeric yarns , wherein when said chain is kept at least taut onto an essentially planar surface, each chain- link has an orthographic projection onto said planar surface , said projection having a foot print area (A), wherein the foot print areas denoted as Ai and A2 of every two adjacent links are in a relation 80%A2≤ Ai≤100%A2 with Ai being the smallest of said two areas and wherein the projection is done in such a way that the ratio of the foot print areas A to A is maximized.</p> |
