ABSTRACT:
A lifting tool suitable for lifting and maneuvering utility access covers, especially manhole covers, including a handle and an arcuate receiving means connected to the handle for receiving and securely retaining the utility access cover during lifting and maneuvering thereof. The cover abuts against an abutment means when it is received in the receiving portion, and a hook is pivotally connected to the abutment means for engaging the tool with the cover. When the cover is engaged with the tool, it cannot accidentally become disengaged and injure the operator, and the provision of a support plate on the bottom of the tool facilitates complete control over the movement of the tool when the cover is engaged therewith.
