This 3.5 km long, 1200mm wide carries 3000MTPH of iron ore with a total connect power of 1050kW. Because of the unique profile, this conveyor required special attention when stopping. However, a relatively inexpensive capstan was added to the take-up to increase take-up resistance during stopping which provided a simple solution to a potential problem.
