The pallet storage tower is designed for the purposes of storage and decoupling in engine production as well as for quasi-automated/fully automated workshop operation. It combines a high storage capacity with a small footprint, is suitable for the most varied workpieces and meets the most diverse production requirements. The workpieces are loaded into the storage tower on pallets and provided for loading/dispensing via flexibly arranged gantry or robot systems. An SPC tray or manual loading/dispenser tray can be integrated where required. The automatic control cabinet featuring standardised software simplifies commissioning and facilitates easy retrofitting.
