One or several TWS take over products or complete load carriers such as pallets in the high-bay shelf storage area. The TRAPO Warehouse Lift (TWL) receives a TWS in order to store and retrieve in the storage lanes via a rail system at different levels. The TWS covers three metres per second at an acceleration rate of 1.5m/s² and completes the cycle of driving out, gripping and driving in in a maximum of three seconds.
