  • Patent number: 10640288
    Abstract: In accordance with presently disclosed embodiments, systems and methods for managing dry bulk material efficiently at a well site or other location are provided. Present embodiments are directed to a rotary clamshell gate actuation system and method, where the gate is separate from the one or more actuators used to open/close the gate. The disclosed system may include a portable bulk material container with a clamshell gate for easily dispensing material from the container. The system also includes a support structure equipped with one or more rotary actuators used to actuate the clamshell gate of the container between a closed and open position when the container is positioned on the support structure. The disclosed clamshell gate actuation system is easy to operate, low cost to manufacture, and reliable even when the portable container is not precisely aligned on the support structure.

  • Patent number: 6261043
    Abstract: A material moving system is disclosed for use in a plant such as a metal foundry. There is an overhead gantry for moving a main hook and auxiliary hook. The main hook carries a container such as a scrap charge bucket. The auxiliary hook carries a multi-function auxiliary tool such as a magnet with a tool hook affixed to the magnet. The scrap charge bucket carries a target member on a saddle on the outside of the bucket. The bucket also has a hold out stand that positions the target member for easy accessibility. The target member is attached to actuator cables that are attached to clam shell bottom members of the scrap charge bucket. The auxiliary tool may be used to lift and pull the target member to open the clam shell members without removing the magnet from the auxiliary hook, saving time. The hook on the magnet is positioned so that the hook does not damage the scrap metal bins or electric arc furnaces when the magnet is used for its usual purposes.
