The mother-child shuttle system is a fully automated and equally versatile storage and retrieval mechanism for multi deep pallet storage. It consists of a Mother shuttle powered by bus bar, which runs on a track perpendicular to the pallet storage in the racking system. It has a pallet shuttle aka child in it which performs the function of storage and retrieval. This system is integrated with vertical lifts that carry the load to its destined position. Once the vertical lift reaches its designated position, the mother shuttle reaches there along with the child. The child takes the load and gets inside the Mother shuttle to again move on the track in order to reach the next destination. Retrieval of loads also happens through the same process.
