The springs need to be inspected regularly to check their load capacity, elasticity, and energy absorption.
These tests are carried out by track and rolling stock maintenance personnel. The test mainly includes the analysis of the impact force on the springs and the resulting correlation with the compression achieved in relation to the height of the helical springs, and, in the case of leaf springs, in relation to the arrows when the force is applied and removed.
The universal spring test bench allows the operator to perform all tests required by applicable regulations and to control force/distance curves.
