<p>A transporting device (10) of a conveyor for free-flowing loose materials, of the type with a cable (11) forming a closed loop along which are secured radial disks (12) for transporting the material, comprises a plurality of pulleys for actuation, tensioning and/or transmission of the cable. To actuate the cable (12) a pair of driving pulleys (16, 17) having the same diameter are coaxially disposed to be operated in synchronous rotation by receiving, in races (18, 19) along their circumference, disks (12) belonging respectively to a first and a second section of the cable. An additional pulley (20) is provided to receive, along its circumference (21), disks (12) belonging to a section of the cable between the sections wound round the first (16) and second (17) pulley of the pair. <IMAGE></p> |
