In the development and engineering of the product, of the utmost importance was providing the metrology lab with a mechanical and pneumatic machine equipped with a load cell and a dynamometer. By setting the reference values and applying a given force with predefined parameters, both in compression and in traction, it is possible to carry out tests (such as the stiffness test) to keep the axial play of the knuckle pin under control both on loose pieces as well as on joints already assembled on the arms.
The values obtained, compared with reference tables and with the standard values required by customer specifications, allow us to provide the results of the stiffness test with the technical documentation that is attached to the normal certifications, something that is now required by the most demanding customers.
