The AP EC 20 PANTOGRAPH series of palletizers is composed of automatic palletizers with mobile heads. The product is picked by the magnetic head (PM), or vacuum head (PV). The picking head movement is achieved using a horizontal trolley transfer system. A pantograph system lifts the product. The magnetic head is equipped with photocells to detect the picking layer level during operation. The Pantograph series can be integrated with automatic layer pad and top frame picking devices to increase the degree of automation during the palletization process, thus reducing downtime.
