A belt conveyor has a carrying belt unit including a carrying belt which has an upper load run and a plurality of supporting rollers to support the latter, and a friction belt unit having a friction belt which has one run in frictional contact with the upper load run of the carrying belt. The friction belt is guided by a plurality of bearing rollers and deviating rollers, the latter being downwardly offset relative to the bearing rollers. The upper load run is trough-shaped and has two lateral inclined portions supported by inclined supporting rollers, and a central portion with which the one run of the friction belt is in contact. The deviating rollers are spaced from one another by a distance which is at most equal to the width of the carrying belt. |
