Apparatus for holding and discharging drums

An interface device for an apparatus for holding and discharging drums comprising:

• a cylindrical tubular element extending along a predetermined longitudinal axis and having opposite open ends, respectively, a first end and a second end;
• a first closure located proximate to said first end, and
• a second closure located proximate to said second end,
• wherein:
• each of said first and second closures can be operated to reversibly move from a closed state to an open state in which it respectively shuts and clears a passage defined by the respective first and second ends, and
• each of said first and second closures comprises:
• a respective first portion rigidly joined to said cylindrical tubular element by a releasable fixation means, to be removed from the cylindrical tubular element and replaced, and
• a respective second portion rigidly joined to an operating member to allow each operating member to actuate the first and second closures, respectively, between said closed and open states,
• wherein said releasable fixation means comprise quick-release fixation means selected from the group consisting of pneumatically, hydraulically and mechanically operated means.
