<p>A link for a tyre chain (10) including a tread portion and flanking side-wall portions with at least the tread portion comprising vertically extending links (12), three or four of which are interconnected by horizontal connectors (14) to form a mesh of a desired shape. The link comprises a base portion (16), a medial portion (18) and a head portion (22), with at least one traction member (15, 30, 32, 36) of a material that is relatively harder than the material of the link partially embedded in the head portion and partially exposed on the surface of the head portion. The traction member may be in the form of tungsten carbide buttons (15, 30) or plates (32) secured in holes in the head portion of the link or may be in the form of a plurality of particles consolidated in a cemented compact or steel matrix (36) that is secured to the head portion of the link, either by being cast or formed on the head portion or by being provided on a body (38) that is weldable to the head portion.</p> |
