ABSTRACT:
A tool which is suitable for lifting a manhole lid that has spaced attachment notches in its top surface is disclosed. In one embodiment, the tool has a substantially rigid support beam. The beam has a first hook adjacent to its forward end which is adapted to be inserted in one of the notches. The beam also has a pivot attachment point adjacent the rear end of the beam. There is provided a second hook which is mounted on the pivot attachment point, the second hook being adapted to be inserted in a second of the notches upon a pivoting of the hook relative to the beam. The hooks will then act to grip the lid between them. To provide a secure grip on the lid, there is provided a catch which prevents the second hook from pivoting back out of the second notch until the catch is released. This catch automatically locks the second hook in the second notch upon movement of the second hook into the second notch.
