  • the lower plate 6 ' is raised by the jacks 62 so that each pair of plate 61' comes into contact with the corresponding coupling sleeve 14 ', in the position shown in FIG. figure 16 which corresponds to the first level H1 for blocking the lower extensions 36 '.
  • this transverse plate 7 comprises on its underside, six pairs of plates 71 'respectively corresponding to the lower coupling sleeves 14' of the six lower rollers 11 'and, on its upper face, five pairs of plates 71 corresponding to the upper sleeves 14 .
  • the upper plate 6 is provided on its underside with five pairs of plates 61 respectively corresponding to the coupling sleeves 14 of the upper extensions 36.
  • first level H1 in the position represented on the figure 17 .
  • This first level H1 is identified by keeping in memory, in the control system of the machine, the positions of the cylinders 62 at this time.
  • the lower crew 1 ' can then be removed from the frame by means of the jack 16, as indicated on the figure 10 and in step B of the figure 9 .
  • the lower rail 60 ' can be raised by means of the mechanical cylinders 62 bearing on the bed 32, driving the lower coupling members 14' which remain tight between the lower plate 6 'and the intermediate plate 7 which is also raised by the lower rail 60 '. Indeed, the two pairs of jacks 82, 82 'being blocked, the vertical displacement of the lower cross member 60' controls a corresponding uplift of the intermediate plate 7 whose support members 81 slide along the slideways 84, and that of the upper cross member 60 whose ends slide in the slideways 83a, 83b.
  • the assembly formed by the lower cross member 60 ', the coupling sleeves 14' and the intermediate plate 7 is thus raised until the upper plates 71 of the intermediate plate 7 come to support the coupling sleeves 14 of the upper extensions, centered at the H2 level.
  • the cylinders 82 then control the lowering of the crosspiece 60 so that the plates 61 forming the upper plate 6 come to tighten, in the position shown on the figure 18 and also corresponding to the figure 12 , on all the upper sleeves 14 resting on the intermediate plate 7 and the lower cross 60 'maintained by the cylinders 62.
  • the upper cross member 60 is spaced apart by the jacks 82 to release the upper couplings 14 and the new crew 1a is lifted by the pressure frame 34.
  • the mechanical cylinders 62 then control the lowering of the lower cross member 60 'and the intermediate plate 7 with all of the lower sleeves 14' which are thus brought back to the first level H1, previously identified, as shown in FIG. figure 13 .
