Abstract
A tensioning assembly for a cable drag conveyor. The conveyor includes a head pulley mounted on a head pulley shaft positioned in a head pulley housing and a tail pulley mounted on a tail pulley shaft positioned in a tail pulley housing, infeed and discharge conveyor tubes interconnecting the head pulley housing and the tail pulley housing, and an endless rope having conveying disks attached to the rope positioned in the infeed and discharge conveyor tubes and around the head pulley and tail pulley. The tail pulley housing is positioned in a stationary position in relation to the head pulley and the head pulley housing. The tail pulley shaft and tail pulley is positioned on the tail pulley housing for movement in relation to the tail pulley housing, the head pulley and the head pulley housing. A tensioner moves the tail pulley to maintain the tail pulley at a distance in relation to the head pulley that results in correct tension on the rope during its travel through the cable drag conveyor.
