The system includes a base and four sidewalls, in which at least one of sidewalls is open. The sidewalls are bolted or welded together in coplanar arrangement on the base. A trident piece with arms and retainer for limiting axial displacement is inserted to the socket formed on the framework of the container to prevent involuntary separation of the system from the container.
