A scraper unit for a scraper-chain assembly is composed of a scraper bar which locates with a pair of coupling pieces at each of its ends. The coupling pieces trap chain links therebetween. The bar has pockets underneath its end regions which locate with the lowermost coupling pieces and recesses open from above which locate with the uppermost coupling pieces. Threaded pins which receive nuts are provided on the lower coupling pieces to engage through bores in the upper coupling pieces and the scraper bar end regions.
