This type of storage operates on the FI-FO principle, includes layers of conveyors next to each other, and with additional layers on top of each other.
Each conveyor will be designated to one specific product, and the trays will be accumulated in each of these.
The feed of trays are handled by a crane mounted with a feed conveyor. The crane moves in the X and Y direction. The out feed of trays is also handled by an identical crane.
