Abstract

Das Hebegerät weist zwei längs einer Grundschiene 5 verschiebbare Schwertklauen 33 auf, die mit ihren Schneiden 40 einander zugewandt sind und in einer auf den Boden abge­ senkten Stellung wahlweise hydraulisch aufeinander zu und voneinander weg sowie hydraulisch angehoben werden kön­ nen. Vor dem eigentlichen Anheben einer Last werden die Schwertklauen 33 zwischen dem Boden und der Last unter diese eingefahren, wobei die Last über geneigte Gleitflächen 39 auf die keilförmigen Schwertklauen 33 aufgleitet. The lifting device has two along a base rail 5 sliding sword claws 33 with their cutting edges 40 are facing each other and in one on the floor lowered position either hydraulically towards each other and away from each other and can be raised hydraulically nen. Before actually lifting a load, the Sword claws 33 between the floor and the load beneath these retracted, the load over inclined sliding surfaces 39 slides onto the wedge-shaped sword claws 33.
