Abstract: In transport containers (3) of this type, in particular spent fuel elements from nuclear power stations are transported to the reprocessing plant. When it is being manipulated in the nuclear power station, this heavy transport container, which weighs over 100 tonnes, must be prevented from falling. To this end, a platform (5) is arranged at a distance "a" below the transport container (3). The platform (5) slides in guide rails (6) while overcoming a certain frictional resistance. A lever system (13) is arranged between the supporting plates (8, 9), which together with the webs (10) form the platform (5). The linkage (35) of the lever system is connected to the transport container via straps (21). If the lifting gear carrying the transport container fails, the transport container will fall more rapidly than the platform (5) overcoming a frictional resistance. The linkage (35) is actuated and presses the brake blocks (15) fastened to the rod end (16) between the guide rails (6) and the abutment (11).
