Mooring device for coal extraction equipment constituted by a conveyor on which a scraper slides, this conveyor being fixed to a carriage mounted in turn on a mooring beam that extends in the direction of the gallery and that can be moved along the beam during the progression of the extraction by a piston placed under the action of a fluid under pressure, characterized in that the displacement of the carriage is ensured by a relatively short advancing or pushing device and constituted especially by a short stroke piston in turn joined to the carriage by a push rod whose point of connection with the carriage can be moved.
