Mining conveyor chain closure link - has central gradually thickened inwards part, with bowed periphery, and narrowing cross section

摘要

Chain closure link for mining conveyor edge chains, which comprises a stirrup-shaped component and one or more connection components connecting the two end parts of the stirrup. The central part of the closure link has a thickened shape (3,4) which is inwardly directed, which is bowed outwards gradually so that in its very centre part it is most curved and has a central rounded part. - The cross-sectional shape of the thickened part (3,4) narrows increasingly with the thickening of the central area.
