3. It is specially designed for testing heavy duty springs of railway rolling stock such as hi-speed railway springs or locomotive suspension springs or vehicle coil springs.Spring vertical & lateral drive and spring vertical force , spring lateral force deflection and spring stiffness measurement are available
4.Drawing of axial load , displacement or deflection , lateral force displacement curve is isochronous. Force sensor and ac servo motor and high precision ball screw vertical and lateral load , the whole process is automatic.
