  • Mobile automatic sandbagger and method of use
    Publication number: 20010032442
    Abstract: A mobile, automatic sandbagging machine includes a source of sandbags and a guide track positioned adjacent to the source of sandbags. A hook attached to a chain of the guide track selectively removes a sandbag from the source of sandbags and advances the sandbag along the guide track. An end of the sandbag is opened under a fill chute, and the sandbag is partially filled with fill material. A closing mechanism closes the open end of the sandbag and the sandbag is removed from the machine.
