Abstract:
1. Chain assembly for plow systems in underground mining, the chain assembly comprising: vertical chain links; and horizontal chain links comprising two chain legs linked at first and second head ends by arrow-shaped bows that in operative use of the chain assembly form power transmission zones with sprockets, the bows each including bow flanks linearly tapered towards each other in a first plane, wherein the first plane is defined by an equatorial line at which the horizontal chain links are symmetrical above and below the equatorial line, the bow flanks being on opposite sides of a curved bow center section and comprising flank surfaces facing outwards, wherein the bow flanks of the horizontal chain links have concave troughs in the flank surfaces in a second plane, the second plane being orthogonal to the first plane, the concave trough being at least below the equatorial line.
