An octabin turner is a device designed to completely and cleanly empty bulk material from octabins. The process is carried out by placing a full octabin in the station and an empty hopper trolley underneath in the raised position. Once the two are joined, the entire assembly is rotated 180° to transfer the material into the hopper car. By opening the outlet, the octabin can then be completely emptied without risk of contamination. The machine is designed for easy handling with a forklift truck.
