Tests for the actuator/transmissions system and for the shock-absorber.

Tests	Results
ACTUATOR/TRANSMISSIONS GROUP
Functional test with no load Upward and downward cycles (overall stroke 50 mm) of the moving slider at the maximum speed, 15 mm/s, and acceleration, 800 mm/s2, continuously for 10 h.	No stop or overheating has been recorded.
Functional test with load In the same conditions of the previous test, an axial 1.000 N tensile load (2 masses of 50 kg) has been applied to the mobile slider for 2 h.	No stop or overheating has been recorded.
Stiffness test of the screw and the guide bar In the plane containing the axes of symmetry of the screw and the linear rail, a static compression 200 N load has been applied perpendicularly to the moving slider, moving at a constant speed equal to 4 mm/s.	No jamming has been recorded along the stroke of the moving slider.
Test of the irreversibility of motion At not powered motor and starting from the position corresponding to the center of the stroke of the moving slider, a compression and a tensile 600 N load has been alternately applied to the moving slider.	No motion of the slider has been recorded.
SHOCK-ABSORBER
Test to check for any jamming of the rod of the shock-absorber At shock-absorber placed in vertical position with a fixed fork, a compression 600 N load has been applied to the other fork.	No jamming has been recorded along the stroke of the rod.
