  • SWING-OUT MANHOLE COVER
    Publication number: 20080063471
    Abstract: A swing-out manhole cover assembly having at least one ramp to facilitate opening and closing the cover. The manhole cover assembly includes a frame, a cover, a swing assembly and at least one ramp. As the cover swings open away from the frame about the swing assembly, the ramp imparts linear translation to the cover separating the cover from the frame slightly. As the cover swings back to close the manhole cover, the ramp reverses the linear translation and the cover returns back to the frame. A spring may be included to bias the cover in the closed position.
