FIELD: machine building.
SUBSTANCE: link chain for scraper-chain conveyer consists of movably connected to each other vertical chain links (1) and horizontal chain links (2). Vertical chain links have similar cross section along the whole perimeter equipped with flat on an external side, and with arc of circumference on an internal side. Horizontal chain links (2) have fore parts (6), external width of which (B2) is bigger, than external width (B1) of vertical chain links and which have straight end zone (7). Lengthwise shoulders (5) of horizontal chain links (2) connecting fore parts (6) have recess (18) on their external surfaces. Horizontal chain links (2) are equipped with gripping devices (21) on both sides in recess (18) for form closure gripping scrapers attached to horizontal chain links (2). A taper is made on profile of cross section of vertical chain links (1) on transition zone of flat into arc of circumference.
EFFECT: improved characteristic of link chain motion with low specific pressure between chain gear and horizontal chain links.
