STORAGE SYSTEM

A storage system includes a framework structure in which storage containers can be stored, a container lift device, and a container transfer device. The framework structure includes at least a first port column through which a storage container may be transferred to or from the container transfer device by the container lift device. The first port column includes an upper end, at which the container lift device is arranged when a storage container is to be lowered or lifted through the port column, and a lower end at which a container buffering assembly is arranged. The container buffering assembly features a container holder frame including a plurality of supports. The container holder frame is horizontally moveable between a first position under the lower end of the first port column and a second position away from the lower end of the first port column. The supports are actuatable between a holding position, in which the supports are configured to support a storage container, and a release position, in which a storage container may pass through the container holder frame in a vertical direction.
