Similarly, from the distances Zi and Z2 and the known distance Xv of the vertical measuring sensors 107, 108, the control unit 111 determines the angle ⁇ , which characterizes a second angular position of the support frame 26 relative to the second pivoting device 31.

  • the distances Xi and X2, as well as the distances Zi and Z2 are repeatedly measured during the positioning of the second support frame end 35, so that the positioning of the second support frame end 35, and thus the alignment of the support frame 26, is monitored and optimized.

L'appareil de traitement (22) comprend également : un dispositif de positionnement (24) pour positionner la seconde extrémité de cadre de support (35), lequel dispositif de positionnement est disposé sur un premier châssis ferroviaire (9) ; et un dispositif de pivotement (25) pour faire pivoter la première extrémité de cadre de support (34), lequel dispositif de pivotement est disposé sur le premier châssis ferroviaire (9). Par conséquent, lorsque le cadre de support (26) est déplacé d'une position de transport à une position de travail, il peut être aligné par rapport à un second châssis ferroviaire (16) d'une manière simple, flexible et fiable.
