Triangulation defects

They are very common after years of operation and successive settings with inadequate tools. The angle of the roller is defined relative to two criteria:

  • it defines the horizontal force (structural design) and the vertical force (load on foundations)
  • the driving requirements (1 or more drive rollers, for example)

In cases when the angles exceed 35 °, it is not uncommon to tilt the bases at 45 °.
