Demtec has a simple palletization system for stacks of crates and/or trays. The stacks are placed in a particular configuration and then pushed over. When the packet is ready to be put on a pallet, the system pushes all stacks forwards. Simultaneously a pallet moves away from underneath the platform and takes up stacks. With a simple pallet carriage or a forklift truck the loaded pallet is removed while the system continues its operation. No waiting time for the stacker and the operator is free to perform other activities.
