Abstract
A manhole lock system includes a frame positioned over an access opening, a cover movable between a closed position in which the cover extends over the access opening, and an open position in which the access opening is exposed; and a lock mechanism for locking the cover in the closed position. The lock mechanism includes a lock member that is movable along a path between a unlocked position and a locked position, wherein in the locked position the lock member prevents the cover from moving to the open position, wherein in the unlocked position the lock member is retracted to enable movement of the cover to the open position.
