摘要： A manway cover assembly can be used to control access to the interior of a railroad tank car or other type of tank or structure. The manway cover assembly can have a tightening system, such as a screw tightening system and an attachment system. The attachment system can have a ledge configured to engage a flange that surrounds an opening. A cover can control access to the opening. The tightening system can secure the ledge to the flange and lock the cover over the opening. A manway cover assembly can also be used for selectively sealing an access passageway of a tank. The manway cover assembly can have an internal seal that remains sealed independent of movement between the cover and the opening within a set range of movement.
