In order to be able to lift or deliver and store shaped parts, such as sectional girders, quickly and without an accident, and in fact with a minimum space requirement for the material to be stored, a load-lifting system is proposed which consists of a cross beam with clamping-jaw pairs pivotably mounted by a synchronising device. It is thereby possible to lift or deliver, for example, individual sectional girders or several sectional girders together quickly and without auxiliary forces and at the same time store them likewise quickly and without auxiliary forces in the smallest space; that is, they can be shifted cost-effectively and without an accident.
