Abstract
A storage tank includes a floor, a roof, a sidewall extending between the floor and the roof, an access hatch provided on the roof and having a base, a lid pivotably coupled to the base, and a latch configured to secure the lid to the base in a closed position, and a system for remotely opening and closing the access hatch. The system includes an elongate arm having a proximal end operatively coupled to the lid, a pull cable attached to a distal end of the elongate arm and extending toward a ground adjacent the storage tank, and a latching cable attached to the latch and extending toward the ground adjacent the storage tank, wherein pulling on the latching cable when the lid is in the closed position actuates the latch to secure the lid to the base in the closed position.
