The bulk container is positioned with the help of a manual lifting trolley or stacker on the hall floor under the magnetic unloader.The magnet then dips into the box at six fixed defined positions. Landing of the magnet is detected with sensors. The magnet is switched on and raised by the lifting mechanism to the required transfer height. The trolley moves the magnet together with the adhering cluster of workpieces and takes the workpieces to the customer's transfer position by switching off the magnet when there.
