ABSTRACT:
A wheeled hand lever tool for lifting, transporting and installing heavy sewer covers that will lift the cover from its side edge. In one form, a T-fitting lifts from an elongated slot through holes in the cover allowing the cover to tilt forwardly for its edge to engage a stop plate on the tool so that the cover is rigidly held by gravity upon the tool. To have added lift advantage, a depending ground-engaging fulcrum is located forwardly of its wheels. For peripherally-notched covers direct engagement is had with diametrically-opposite notches by use of a secondary lifting arm that is lowered from the lifting arm of the tool.
