Abstract

See full text

A hand-operated tool for removing and replacing a wide variety of different manhole covers is disclosed. The tool includes a handle which extends upward from slip-resistant feet. A collar with forward extending ears attaches to the lower, central region of the handle. An S-hook is positioned within the ears so that its hook extends downward and frontward, and a clevis is positioned outside the ears. The S-hook, clevis, and ears are all bolted together. One end of a chain attaches to the clevis, and another end of the chain attaches to a link of an elongated link-up unit. The link-up unit's link is dimensioned for snug, but hand-removable, attachment to the S-hook. The snug attachment resists rotation between the link-up unit and the S-hook. A hook pivotably couples to the link-up unit at an opposing end from the link-up unit's link. The hook is coupled so that is can pivot up and down only, and cannot freely rotate around the general direction of elongation of the link-up unit. The hook extends downward and forward. The link-up unit is further configured to include an integrally formed claw. This claw extends rearward and slightly upward from the lower region of the link-up unit.
