Abstract (en)
[origin: EP0254752A1] An apparatus for operating and transferring a manhole cover is disclosed which is capable of being applicable to a manhole cover formed with any through-hole type operating hole and preventing the disengagement of the manhole cover from the apparatus. The apparatus (30) includes a lever body (32) having a pair of operating arms(52, 52). The operating arms (52, 52) each have an eccentric hanging hook (36) pivotally mounted thereon and a press member (74) which is adapted to abutted against a manhole cover (20) to horizontally support it during the lifting operation. The hanging hook (36, 36) comprises a vertical support member (56, 56) pivotally mounted on the operating arm (52, 52) to be pivotally moved in the longitudinal direction of the apparatus (30) and a hanging member (58, 58) connected to the support member (56, 56) to inwardly extend therefrom in a manner to be deviated from a pivotal axis (54, 54) of the support member (56, 56) in the direction opposite to that of a point of force (40). The apparatus (30) has a manhole cover lifting position which is deviated toward the press member (74, 74) with respect to the gravity line of the manhole cover (20).
