A lid lifter mount is installed on the hinge pin of a conventional manway lid, and has a compression spring assembly engaging a lever which is also installed on the hinge pin. The lever has a bar engaging a lid hinge arm. A spring force adjustment screw connected to the mount enables adjustment of the amount of lift assist the bar applies to the hinge arm by cam action against the arm as the operator lifts the lid. Two embodiments are shown for attachment to two types of lid hinges.
