Abstract
A pan for a scraper-chain conveyor has sigma-shaped side walls and a floor plate extending between inwardly facing central flanges of the side walls. An opening is provided in the pan which interrupts the floor plate and an upper region of one of the side walls. A detachable unit is then inserted into the opening to close the latter. The unit has a plate portion matching the floor plate and a side portion matching the upper region of the interrupted side wall. A support on the outside of this side wall engages with a bar carried by the unit. To lock the unit in place securing which acts solely on the side portion and the remaining side wall of the pan is used.
