### Moline Belt Trackers

fabric belts such as neoprene. The unit is designed to accommodate conveyor widths of 24 to 60 inches. When the conveyor belt begins to move out of alignment it contacts the belt tracker actuator located beneath the conveyor bed. The actuator sends a signal to the air cylinder to shift the tracking rollers and realign the belt.

Elastic elongations of a belt loaded with a longitudinal force cause a reduction of forces in the zone where the belt comes off the drive pulley . This necessitates causing much greater forces of preliminary belt tensioning. Permanent deformations of the belt are periodically compensated by moving the tensioning pulley during conveyor stoppages.
