Superior Industries enhanced the belt tracking on its TeleStacker Conveyors to maintain level movement while in radial travel mode. According to Superior, uneven conveyor structure is a main cause for inaccurate belt tracking. The belt tracking technology allows the telescopic radial stacking conveyor to keep a balanced conveyor structure. Auto-level technology comes standard on all FD Axle model TeleStacker Conveyors equipped with PilePro automation. Additionally, Superior manufactures FD Axle models in lengths of 110 ft., 130 ft., 136 ft., 150 ft. and 158 ft.
