  • Manhole cover safety device
    Patent number: 8449216
    Abstract: A manhole cover assembly includes a frame that includes a central opening and a safety stop portion, and a cover hingedly attached to the frame such that the cover is pivotable between a closed position covering the central opening and an open position providing access to the central opening. A safety device is connected to the frame and the cover for locking the cover in the open position. Movement of the cover to the open position automatically moves the safety device to a locked position in which said safety device engages the safety stop portion and prevents movement of the cover to the closed position. When the cover is open, the safety device is manually movable between the locked position and an unlocked position in which the safety device is disengaged from the safety stop and permits movement of the cover to the closed position.
