    摘要: The present invention provides a system for automatic operation of a top hatch cover for a container, comprising a hatch cover, a cylinder mount, a main operating lever, a connecting link, and a hatch locking lever. The cylinder mount is configured for pivotally connecting a piston to the container. A lower portion of the main operating lever is connected to a cylinder rod of an air cylinder. A first extension of the connecting link is rotatably connected to an upper portion of the main operating lever and a second extension of the connecting link is coupled to the hatch cover. The main operating lever and the hatch locking lever are rotatably coupled to a main shaft mount, where the hatch locking lever is configured to pivot around the main shaft mount to move between a locked position and an unlocked position.

    摘要: Systems and methods for actuating automatic sliding doors on railroad hopper cars are disclosed. The system includes a cylinder having a first cap end mounted on a hopper car, and a second rod end having a clevis. The cylinder has a piston rod which extends, causing an actuating reinforcer coupled to the clevis to rotate around a coupled main shaft. The rotational motion of the actuating reinforcer causes an operating lever, also coupled to the main shaft, to rotate. A connecting link translates the rotational motion of the operating lever to a door pan fulcrum mounted to a sliding door, causing the door pan fulcrum to pull the sliding door open. The system also enables automatic locking in an analogous way, with the door pan fulcrum pushed to close the sliding door, when the cylinder piston rod returns to its original position.
