1.The spring lateral rigidity tester is researched by Wintime Machinery Co.,Ltd for secondary suspension for locomotive or vertical and lateral of railway spring also called

stiffness testing machine which obtains proprietary technology .

2.It is corresponding with the European Standard EN13298 and is used for testing the spring free transverse deflection,spring free bowing ,spring transverse stiffness or lateral stiffness(rigidity)

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.
