<p>A lifting fork intended to be suspended from a lifting member, e.g. a lifting hook (4) of a hoisting crane, and which comprises forks (2), a lifting shank (3) to which a movable attachment means (7, 11; 14) for the lifting hook (4) is attached, and a connecting bar (5) extending betwen 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 said attachment means (7, 11; 14) is movable from said 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 means (7, 11; 14) being displacable 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.</p> |
