18 ABSTRACT OF THE DISCLOSURE A lifting device includes lower arm and upper arms and an intermediate portion bridging between the arms. A suspension link is pivoted at its bottom to the upper arm, and has a hook latch at its upper end for engagement with a crane hook. A telescopically guided spring exerts a separative force between a location on the link and a further location on the upper arm, which force tends to pivot the link toward the closed end of the hook. The latch has a strike panel which can be contacted by the crane hook in order to bring the latch into engagement position. The intermediate portion of the lifting hook is provided with a horizontally slidable shock absorber casing.
