Abstract
A scraper unit for a scraper-chain assembly is composed of a scraper and a clamping strap which define beds for receiving one or more chain links. The clamping strap is fixed to the scraper with the aid of nuts and bolts and one or more pivot joints formed between the strap and the scraper ensure that when the nuts are tightened onto the bolts, the clamping strap pivots on the scraper to clamp the chain link or links into position.
