Abstract: A container handling and flow system comprising a plurality of base elements (1, 31) for mounting on top of containers and fasteners for locking the base elements on to corner fittings (14) of a container. The base elements are elongate and have a length corresponding to the width of the containers to be handled, said system possibly including base elements of different lengths corresponding to different container standards. The fasteners are arranged one at each end of the base element at a distance corresponding the distance between the corner fittings. The base elements have sufficient strength and stiffness for allowing the load of a second or more container(s) resting on top of or moving across a pair of base elements mounted on a first container.
