Abstract
A fluid-driven hatch for a bulk material container includes a cover is opened by a fluid-driven cover actuator and secured by a fluid-driven lock actuator. A fluid conduit connects both the fluid-driven cover actuator and the fluid-driven lock actuator to a pressurized fluid source. Pressurized fluid is selectively supplied to the fluid conduit such that the fluid-driven lock actuator is actuated at a first pressure to unlock the cover, and the fluid-driven cover actuator is actuated moments later at a second, higher pressure to open the cover.
