Abstract
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.
