A scraper chain conveyor has symmetrical scraper bars (12) connected to endless chains extending inboard of inwardly directed lips (64, 66) of the side flanges (8) of the pans (9). Each scraper bar includes a central portion (14) of a width slightly less than the distance between edges (10) of the upper lips (66) across the pan, and, secured thereto by bolts (52, 54), outer portions (16) extending as wings (34) into the side flanges to run on the bottom lip (64). The chain is retained on seatings (17) formed on the central portion (14) by retaining faces (32) formed on the outer portions (16). |
