The force was verified on the pin of part "27620_1020", which was thought to be one of the critical points. It suffers a tension of around 40MPa (any steel resists).
Changes:
Normalize to 10 mm the maximum of components
Change the shape of the large bars (PerfilRedondo_20)
As purchased components (exc. "27624-10") must not be changed to obtain a greater working range, the inclination of the large bars can be changed.
In order to obtain a greater working range, it was not decided to change the inclination of the large bars as initially stated, it was decided to change the length of the upper arms from 100 mm to 120 mm.
