FIELD: transport.SUBSTANCE: belt conveyor drive comprises first and second driven drums (2) and (3) for conveyor belt (1) to run there over, deflecting drum (4 and tensioning drum (5, extra deflecting drum (7) and compensation drum (8) for pressure belt to turn there over and tensioners (9, 10). Extra deflecting drum is arranged between first and second drive drums to be pressed to conveyor belt. Pressure belt runs over extra deflecting drum, second driven drum and compensation drum. Compensation drum reserve is larger than that of tensioning drum.EFFECT: higher drive thrust.2 dwg |
