  • Patent number: 6418841
    Abstract: A system and method for compressing scrap metal. The scrap metal is compressed in a portable container. The container rests on two scales that rest above the ground surface. The fullness of the container is primarily evaluated based on the weight of the container. The scrap metal is initially delivered to a static compactor to which the container is mated. The compactor includes a ram that forces the scrap metal into and compresses the scrap metal in the container. The weight of the container is continually monitored while the container is mated to the compactor. The actuation of the ram is controlled so that, as the amount of scrap metal in the container increases, the frequency with which the ram is actuated increases. After the volume of scrap metal in the container increases above a certain level, each actuation of the ram actual comprises running the ram through plural extension and retraction cycles.
