Really；
3) steel wire (4) lower end passes through the center bolt (11) of the anti-steel wire pendulous device (8) of sill (6), by adjusting
Whole anti-steel wire pendulous device (8) makes center of the steel wire (4) in support (1) bottom plate endoporus, it is ensured that steel wire bottom is looked for
Center position is accurate；
4) steel wire (4) is exceptionally straight by scale pan (9) gravity tensioning, realizes in operating process all the time with a fixed tension
The exceptionally straight steel wire of power, when overcoming conventional steel wire two ends bolt tension, because steel wire elastic deformation is to the transformation of plastic deformation
The reduction of the Wire pulling power for causing, current process causes steel wire elongated in centering center；
5) center bolt (11) of anti-steel wire pendulous device (8), top center has hole, the latter half to have a skewed slot, hole and tiltedly
Groove causes steel wire to pass through by side hole wall and opposite side cell wall along broken line, so plays steel wire (4) position and does not uniquely swing
Effect, steel wire swings brought certainty of measurement problem when overcoming measurement；
6) the steel wire crossbeam of this invention, during positioning bar (2) centering of some months and welding post-equalization is up to, steel wire
(4) as reference measurement data redundancy very well, measuring speed and precision are fine.
