Abstract: A belt conveyor for a road-finishing machine or a charger. The belt conveyor includes a conveyor belt in which a displaceably mounted support element abuts the conveyor belt, and a first and a second piston cylinder unit operate to displace the support element. The first and the second hydraulic piston cylinder units can be pressurised independently of each other in order to move the support element into a desired inclined position. If the conveyor belt of the belt conveyor runs laterally away from the support element, the out-of-true running of the conveyor belt can be counteracted by an inclined position of the support element which moves the conveyor belt back into its original position.
