Abstract
A link component is adapted for interfitment with like link components to form a flexible chain free of hinge pins and cooperable with a drive sprocket. The link component has complementarily-shaped end parts (10, 11; 10' 11') whereof each is the true or inverted image of the other. Each end part comprises a transverse recess (20) located between transverse walls (21, 22) of which the longitudinally outer wall (22) is shorter than the inner wall (21). The shorter end of the outer wall (22) and the recess (20) have complementary rounded formations so that when the end part of one link (10 or 10') interengages with the end part (11 or 11') of an adjacent link, the respective outer walls (22) locate in the corresponding recess (20). Parallel side braces (12, 12') space the end parts (10, 11; 10' 11') apart through integration therewith and have external surfaces spaced laterally beyond the width of the end parts. A scraper-chain conveyor comprises conveyor line pans (26) and a mining machine movable therealong, said pans having elongate channel sections (13) in which a haulage linkage is located for engagement by drive sprocket means (35) on the machine, said haulage linkage comprising a plurality of link components as above defined, each component interfitting with adjacent components and being held captive in the channel section by flanges (14) of the channel section which overhang the spaced parallel side braces (12, 12') of the link components.
