Abstract
A manway assembly features a nozzle defining a central opening. The nozzle has a groove or a plurality of grooves. A hinge pivotally attaches a cover to the nozzle so that the cover may be pivoted between an open position, where the central opening is generally uncovered, and a closed position, where the central opening is generally covered by the cover. Retainers secure a plurality of latch segments to the cover so that the latch segments may slide with respect to the cover. A latching mechanism moves the latch segments into engagement with the groove of the nozzle sidewall when the cover is in the closed position. The latching mechanism also removes the latch segments from engagement with the sidewall groove when the cover is to be opened.
