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.
摘要（中）：
可以使用人行道盖组件来控制对铁路车厢或其他类型的罐或结构的内部的通路。 人行道盖组件可以具有紧固系统，例如螺钉紧固系统和附接系统。 附接系统可以具有被构造成接合围绕开口的凸缘的凸缘。 盖子可以控制对开口的访问。 紧固系统可以将凸缘固定到法兰上，并将盖锁在开口上。 人行道盖组件也可用于选择性地密封罐的进入通道。 该井架盖组件可以具有内部密封，该密封保持密封，独立于盖和开口之间在一定运动范围内的运动。
