Abstract (en)

[origin: EP0540931A1] A parallel arm-guiding system for the parallel displacement of supporting arms as well as a method of adjusting parallel supporting arms laterally are designed in such a way that the supporting arms, displaceable in parallel, do not undergo different deflection under load. This is avoided by the parallel arm-guiding system having an intermediate supporting plate (1) which has at least one horizontal (2, 4) and two vertical (3, 5) legs (2 - 5). It can be fastened to a stacker or transporter via a lifting plate belonging to the stacker or transporter. Two double-spindle systems (10 - 13) are provided which are arranged one above the other on one of the vertical legs (3, 5) and have double spindles (10o, 10u - 13o, 13u). An outer supporting arm (20a, 21a) is mounted in a horizontally displaceable manner on one spindle each (the bottom spindle) of the double spindles. With the other respective spindle (the top spindle), each of the double-spindle systems (10, 11; 12, 13) provided one above the other is mounted via second bearings (6o - 9o) in such a way as to be horizontally displaceable relative to the intermediate supporting plate (1). The method relates to the adjusting action of the aforesaid parallel arm-guiding system. <IMAGE>
