ABSTRACT:
An adjustable height beam support (11, 12) is fastened to a frame (1) mounted on wheels (6 to 9); a vertically moveable sliding carriage (14) carries a rotatably mounted pressure beam (13). By means of double-acting hydraulic cylinders, two pressure arms (13a, 13b) slidingly mounted on the pressure beam (13) can press outwards against the container side walls or--with the pressure beam set vertically--against the bottom and the top of the container. Deformations of the container walls can, in this manner, be corrected without large expenditure of time and money. A mobile hydraulic cylinder (23) can be applied to both the frame (1) for moving the equipment into the container and to the pressure beam (13).
