A lifting fork intended to be suspended from a lifting member, e.g. a lifting hook (4) of a hoisting crane, and which includes forks (2), a lifting shank (3) to which a movable attachment (7,11,14) for the lifting hook (4) is attached, and a connecting bar (5) extending between the forks and the lifting shank. In order to facilitate the withdrawal of the forks (2) from the load the point of action of the lifting force at the lifting fork by moving the attachment (7,11,14) is movable from the position at the lifting shank (3) to a position close to the rear end of the forks (2). This can be achieved in many ways, i.e. by means of the attachment (7,11,14) being displaceable from the lifting shank (3) down along the connecting bar (5) or by the connecting bar (5) or a part thereof possibly together with the lifting shank being pivotable backwards - downwards.
A lifting fork adapted to be suspended from a lifting member and which is substantially U-shaped, where a multi-tined fork constitutes one shank of the U while the other shank of the U, constituted by a lifting shank, is adapted to receive a movable attachment means for said lifting member, and where the intermediate portion of the U, extending between the two shanks, comprises a connecting bar, said lifting fork further comprising:
