<p>A link (1) of a conveyor chain, comprising means for articulated connection to a similar and adjacent link (1) and a main base body (2) which comprises two shoulders (10a, 10b), which protrude upward from the ends of the transverse sides of the main base body (2) and are arranged parallel to the direction of advancement of the chain, the ends of a pair of first and second shafts (9a, 9b) being associated with the pair of shoulders (10a, 10b), first rollers (14) being rotatably associated with the shafts. Second rollers (15) are associated on the pair of first and second shafts (9a, 9b), have a smaller diameter than the first rollers (14), and are supported in a loading condition by at least one pair of first supporting elements (12a, 12b, 12c, 12d), which can be activated when a load passes and protrude from the main base body (2) and lie on the same plane or on a different plane which is transverse with respect to the pair of first and second shafts (9a, 9b). The link (1) further comprises a slider (9c), which has an upper surface (60) which lies on a plane which is approximately tangent to the adjacent lateral surfaces of the first and second shafts (9a, 9b), the slider being supported by at least one pair of second supporting elements (51a, 51b), which protrude from the main base body (2) and lie on a plane which is parallel and distinct with respect to the plane of arrangement of the first supporting elements (12a, 12b, 12c, 12d), the ends (52a, 52b) of the slider (9c) being free and being supported on the main base body (2).</p> |
