FIELD: transport.
SUBSTANCE: belt conveyor consists of closed on drums belt resting by load-carrying branch on cylindrical roller bearings. Roller bearings of inoperative branch are shifted relative to roller bearings of load-carrying branch along conveyor and installed with possibility of inoperative branch belt to interact with rollers of load-carrying branch. End drum is made driving with synchronisation of its circumferential speed with circumferential speed of head drum. Rollers of roller bearings of inoperative branch of conveyor belt are shifted in vertical plane relative to rollers of roller bearings of load-carrying branch with possibility to provide maximum angle of wrapping the rollers of load-carrying branch from below by inoperative branch. Rollers are placed from the side of belt inoperative branch running on roller bearings of load-carrying branch.
EFFECT: increased conveyor length, its productivity and lifetime of conveyor belt.
