<p>An articulated track is disclosed. Each unit of the track includes a link (1) and a road pad (15) and the invention provides simple methods of retaining the latter on the former whilst allowing easy release. In one embodiment, the pad (15) is retained by passing a rollpin (21) through aligned bores (13, 14) in the link (1) and the pad (15). The two are released by pushing the rollpin (21) further into the link until it comes free of the aligned apertures. In another embodiment, a spring clip (25) on the pad engages a detent (30) on the link when the pad is offered up to the link from below. The detent is preferably an aperture which allows insertion of a tool to free the clip from the link.</p> |
