    摘要： A manhole cover includes a base with at least one opening therein to define a grate portion. A lip extends axially from the base along the outer circumference thereof, the base and the lip defining a recess. The manhole cover also comprises a composite portion comprising a composite material, the composite portion including a composite body defined by a top surface and a bottom surface. At least one aperture extends through the composite body, the top surface, and the bottom surface, the at least one aperture configured to receive at least one fastener, the at least one aperture configured to align with the at least one opening. The composite portion is configured to fit within the recess.

    摘要： An example manhole cover assembly includes a manhole cover and a latch assembly. The manhole cover is supportable by a seat of a manhole frame. The latch assembly includes a latch housing fixedly coupled to the manhole cover. A latch plunger is slidably coupled to the latch housing. The latch plunger includes a follower arm. A latch lever is rotatably coupled to the latch housing. The latch lever includes a stop. The latch lever is rotatable relative to the latch housing between a locked position and an unlocked position. The stop is structured to engage the manhole frame when the latch lever is rotated to unlocked position so as to force the manhole cover away from the frame.

    摘要： A manhole cover assembly comprises a base frame, the base frame comprising a base body and a base flange extending laterally outward from the base body. The assembly further comprises a top frame, the top frame comprising a top body disposed annularly about at least a portion of the base body, a top flange extending laterally outward from the top body, and a lip extending laterally inward from the top body.

    摘要： A manhole cover assembly includes a manhole cover supportable by a manhole frame. The manhole cover defines a latch bore having a longitudinal axis. A latch housing extends from the manhole cover, and a latch assembly is positioned at least partially therein. A first end of a latch yoke extends through the latch bore and slidably couples the latch yoke to the manhole cover along the longitudinal axis. A latch member is rotatably coupled to the second end of the latch yoke about a first transverse axis perpendicular to the longitudinal axis. The latch member is also rotatably coupled to the latch housing about a second transverse axis spaced from the first transverse axis. The latch member is selectively rotatable relative to the latch housing about the second transverse axis, between a locked position and an unlocked position, via sliding the latch yoke relative to the manhole cover.

    摘要： A manhole cover assembly includes a manhole cover and a latch assembly. The manhole cover is movable between a seated position in which the manhole cover is supported on a seat of a manhole frame, and an unseated position in which the manhole cover is displaced relative to the seat of the manhole frame. A shock absorber includes a housing fixedly coupled to the manhole cover. The housing defines a cylinder. A piston is slidably coupled to the cylinder. A rod is fixedly coupled to the piston. A spring is positioned within the cylinder adjacent the piston. A latch is fixedly coupled to the rod. In response to a pressure applied to the manhole cover, the latch assembly is configured to permit limited displacement of the manhole cover relative to the seat of the manhole frame, and to controllably dissipate energy relating to the pressure.
