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.
Claims9
A sewer cover lifting tool comprising an elongated lifting arm, a cross-body connected to the forward end of the lifting arm and having supporting wheels journalled thereon;
- a depending fulcrum extending from the lifting arm for engagement with the ground to be effective for the initial lifting action close to the cover, a fitting attachment adapted with a sewer cover forward end of the lifting arm forwardly of the ground-engaging fulcrum and adapted for detachable engagement with edges of a sewer cover, said fitting attachment being so constructed as to have lifting engagement at one point on the sewer cover and dependent for further lifting engagement with the lifting arm at another point on the cover whereby the sewer cover will be bodily lifted from two points out of its opening when the lifting arm is lowered.
