  • Patent number: 7104425
    Abstract: A method for loading and unloading of dry bulk freight containers vertically, and a device in the form of an improved intermodal dry bulk freight container for vertical loading and unloading. Standardized corner locks may be used and dimensions may be selected so as to provide a standardized cargo container. The present invention teaches that an intermodal dry bulk freight container may be loaded in either the customary horizontal orientation of such devices, or in a vertical orientation in which one end is opened and elevated. In particular, however, such a container may advantageously be emptied by elevating it into the vertical orientation. The method of the invention is thus to provide only a single hopper and yet allow one hopper to empty the entire container, as well as providing a more efficient gravity feed of bulk cargo as it is off loaded. The present invention furthermore teaches an intermodal dry bulk freight container suitable for this method of operation.
