These high-capacity units feature a lagged drive roller, troughing idlers, rubber disc return rollers, and an automatic belt tensioning system. High quality CEMA rollers with sealed bearings are used throughout the conveyor. The tri-rollers are mounted on a heavy-duty channel frame, capable of supporting a tripper in an overbin application, eliminating the need for additional framework or bracing.
