GROUND OPERATED ROOF-BASED ACCESS HATCH FOR A FRACKING SANDBOX
A ground operated roof-based access hatch for a sandbox associated with fracking includes a door panel positioned atop the sandbox and movable between an open configuration allowing access to an interior of sandbox and a closed configuration preventing access thereto. The access hatch includes a linkage having an access control portion operatively coupled to the door panel and configured for moving the door panel between open and closed configurations when actuated and an operator control portion positioned at a bottom of the sandbox that is configured to transmit movement data from an operator to the access control portion, whereby the operator is able to control movements of the door panel from a ground surface. The linkage may include a sprocket and gear assembly having an elongate rope or chain that is both operable a bottom at of the sandbox and operable to open or close the access lid.
