Mosaic Company, Colonsay Mine - UNDERGROUND BIN REFURBISHMENT
In this project Fortis leveled the bin structure and replaced the suspension cables that supported the bin. The new cables were equipped with load cells for uniform and controlled tensioning. The load cells will allow for close monitoring of the loading on the cables. Fortis built a cat walk to enable the maintenance personnel to check the cables and the load cells. The maintenance personnel can visually inspect each cable and load cell and make adjustments as required.
