Inlet closure system

The invention relates to an inlet closure system for covering an inlet (I) formed in an upper region of a container body (12). The container body may a storage region of a hopper, a hopper vehicle (10) such as a hopper railway wagon or other storage devices. The inlet closure system comprises at least one closure member (14a, 14b) arranged substantially above the inlet and moveable between a first closed configuration in which the inlet is substantially closed and a second fully open configuration in which the inlet is substantially open, and at least one actuator (18a, 18b) mounted on an end wall (12b) of the container body for moving the closure member. The actuator remains below an upper edge (12be) of the end wall when the closure member is in the second fully open configuration.
