The apparatus includes a lever body having a pair of operating arms. The operating arms each have an eccentric hanging hook pivotally mounted thereon and a press member which is adapted to abutted against a manhole cover to horizontally support it during the lifting operation. The hanging hook comprises a vertical support member pivotally mounted on the operating arm to be pivotally moved in the longitudinal direction of the apparatus and a hanging member connected to the support member to inwardly extend therefrom in a manner to be offset in the direction opposite to that of a point of force. The apparatus has a manhole cover lifting position which is offset toward the press member with respect to the centre of gravity of the manhole cover.</p> |
